Mark Dvoretsky

P reface

Pfamiliar with the fi rst two books, based

erhaps, dear reader, you are already

on material from the Dvoretsky-Yusu pov school for talented young players (Secrets of Chess Training and Secrets of Opening Preparation). Then you will already know the main principles by which we are g u ided . We have held several thematic sessions of the school, devoted to a particu lar aspect of improvement in chess. The aim of the sessions was not to convey specific infor­ mation - for this we had too l ittle time. It was fa r more importa nt to discover the deficien­ cies in the pupils' play and to help them to eradicate them, to demonstrate the most effective ways of studying chess , and to acquaint them with general mechanisms, ideas and methods of play. You now have before you the th i rd book (there are five i n all). It is based on our work at the th ird session of the school , devoted to the problem of improving endgame and tech nical mastery. During recent years the reg ulations for tournaments and matches have changed sign ificantly - now games are hardly ever adjourned . Previously, after taking play i nto an end i n g , you could investigate its subtle­ ties in home analysis, whereas now you have to act directly at the board . Without an excellent knowledge and, what is even more important, understanding of the laws of the endgame, it is not easy to cope with this task, especially if account is taken of accu mulated fatigue from the preced ing battle. And yet endgame mista kes are the last in the game - it is no longer possible to repair them! It is clear that today the importance of endgame and tech n ical mas­ tery has grown sharply.

I n my bookcase there are nu merous weig hty tomes devoted to the theory of endings. Is it conceivable to assi milate and remember all the information conta i ned i n them? It turns out that it is not at all necessary to do this. After read ing the fi rst part of this book, you will see that 'your' system of endgame knowledge can and should be compact, easy to assi milate and remember, and you will learn how to develop it, by making the acquai ntance of certa in i m po rta nt sections of the theory of rook and minor piece endings. The second part of the book is devoted to an analysis of complicated practical endings. Such an analysis helps to deepen and consolidate endgame knowledge, and aid the development of traits of character and thinking necessary to every player. The tech n ique of converti ng an advantage is a stu mbli ng-block for many players. To raise your tech n ical mastery req u i res developing i n yourself certa in importa nt skills i n seeking and ta king decisions, moreover not purely chess , but, so to speak, 'psycholog ical­ chess' decisions. The question of how to improve your tech n ique is exam i ned i n the third part of the book. Here a re both the 'theory' of this question, and its practical application - both by a critical analysis of games played by young players , and at the very hig hest grand master level . By trad ition , the final part is devoted to an analysis of games by the pupils of the school. This book was fi rst publ ished i n the 1 990s. During the preparation of this new edition I checked all the games and endings on a computer, which , natu ral ly, gave rise to

Preface

numerous improvements and additions. I n addition , a qu ite large chapter has been added , one which was written many years after the fi rst edition was publ ished . I n it some instructive examples of the successful or unsuccessfu l solving of complicated tech nical problems a re analysed - they will help you to understand more deeply the tech nique of converting a n advantage, a

problem which is exceptionally i mportant for every player. Practically all the players whom I have trai ned have possessed good tech nique and an excellent u n derstanding of the endgame. This means that the working methods described in this book have stood the test of time. I hope that they will also prove su itable for you .

All endgame positions can be arbitrarily d ivided i nto 'exact' and 'problematic' . Posi­ tions which are familiar to us, i n wh ich we know beforehand the evaluation and correct plan of action, we cal l 'exact' . Note that they are familiar to us, and not to the theory of endings in genera l . Different players have d ifferent stores of exact positions.

Two main ways of improving in the endgame can be disti ngu ished :

All rema i n i n g positions belong to problem­ atic. I n them we do not demonstrate our knowledge, but fig ht, seek the best moves , and calculate variations - in short, we play.

not be averse to improving their endgame mastery, but they don't know exactly how to do this. I n chess l iteratu re practically noth ing is said about methods for the i ndependent study of endgame theory. We will now endeavour to partly fi ll this gap.

I . The study of theory (development of erudition, en richment of the store of end­ game knowledge). I I . Improvement in the general tech nique of endgame play. It stands to reason that these two d i rections are closely inter-connected , and prog ress in one of them i nvariably leads to progress i n the other. However, let us nevertheless consider them separately. I. THE STUDY OF THEORY To expand your store of knowledge you need to make a systematic study of various types of endings. Here the traditional divi­ sion by material is q u ite appropriate. By successively exami n i n g , for example, pawn, knight and queen endings we assimilate the specific featu res of these types of endgame.

A na"ive opinion is prevalent, identifying the mastery of endgame theory with a knowl­ edge of nu merous exact positions. But is a large store of specific knowledge really necessary? After a l l , exact positions (apart from the most elementa ry) occur rather rarely i n practice . More often a player has to fig ht in problematic situations. He should study the general endgame laws which apply in them and the most com mon reg ularities, playing methods and typical eval uations. All this, together, of cou rse, with the most important exact positions, is what comprises the i nteg ral system of our endgame knowledge. I must once again emphasise: the store of positions which you need to know exactly is

CLJ

comparatively smal l . Only in rook endings do you need to have a firm knowledge of several dozen specific positions; in other types of endings - much fewer. When studying them it is often not necessary to delve into complicated analyses - it is sufficient merely to remember the main conclusions. Take, for example, rook endings with f- and h-pawns. They occu r q u ite rarely, but never­ theless they do occu r, so that it would be useful to obtain some impression of the m . However, i t is hardly advisable t o study the entire theory of this type of endgame - it is just too complicated . What, the n , from this theory should the practical player add to his armoury? Above all, the i nformation that such endings are normally d rawn . It is useful to examine a practical ending , demonstrating the main defensive ideas.

Draw. An examination of such an ending helps us to draw certain general concl usions. We now know where Black should place his rook. And the king, as was shown by l lya Maizelis, is best kept at f7 u ntil there is a danger of it being driven onto the back ran k . Then i t can stand a t g7 and su bsequently even at h6, attacking the wh ite pawn. It stands to reason that by no means all positions with f- and h-pawns are d rawn . The most important exception has already been mentioned several times - when Black's king is cut off on the back rank, he normally loses.

7 f8 The next move will be 8 f7 (the h5-pawn deprives the black king of the g6-sq uare). It is sufficient to play through th is variation just once on the board - there is no need to memorise it, especially since Wh ite also has other ways to win. This is probably a l l that the practical player needs to remember about the g iven type of ending. As you see , not really so m uch and not really so d ifficult! Let us see how another, rather more ex­ tensive section in our system of endgame knowledge is constructed - the theory of endings, in which a rook fights against pawns. A basis for study can be provided by any endgame manual , for example, l lya Maizelis's monograph Ladya protiv peshek (Rook against pawns), published in 1 956 (in contrast to opening books, those on the endgame hardly date at a l l ) . Here some 400

ltJ

How to Study the Endgame

positions are examined . Clearly we are not able to study and remember all this i nforma­ tion . We need to select the most impo rta nt key endings for practical purposes.

11

C utti ng off of the king

But how to choose the most important material? This is the main problem . What tells here is the player's i ntel lect, and his abil ity to work with books , to general ise, and to draw conclusions. He is also helped by the knowledge (even if incomplete) that he already has, and by his own practical experience in the g iven field . The play i n endings with rook against pawns is dynamic in character, and every tempo has a decisive i nfluence on the outcome. It follows that here there is no large-scale strategy, battle of plans, or deep regularities (as, say, in endings with opposite-colour bishops). There a re also hardly any exact positions, by relying on which we could avoid the need for concrete calculation. The main role is played by a knowledge of typical techniques, which help the correct move to be found more qu ickly and variations to be calculated more certa i n ly.

Wh ite wins, by playing 1 .l:tg5 ! . When the pawn reaches a3, it ca n be eliminated by llg3 (or with the pawn on a2 - by l:.g 1 and l:r.a 1 ) . If it is Black to move , then 1 .. .'it>b5(c5)! leads to a d raw - as it is easy to see, cutti ng off the king along the 4th ran k by 2 l:tg4 does not ach ieve anyth ing. Promotion of the pawn to a knight

The procedu res a re best mastered with the help of elementa ry positions, in which they are employed and where their action is not obscured by extraneous analytical details. Su bseq uently the exact pattern of the position my be forgotten , but the impression of the tech n ique will remain . Sometimes such a position - the conveyor of the technique - is simu lta neously an exact position which is i mportant for us; in this case, of cou rse, we should memorise it. So, using some very simple schemes, let us examine the main ideas which apply i n endings with rook agai nst pawns. 1 l:.h2+ 'it>c1 2 'it>c3 b 1 lD+ ! 3 'it>d3 lb a3 4 l::ta 2 lbb1 1 with a d raw, but not 4 . . . lbb5? (in endings with knight against rook, the knight should not be separated from the king). A d raw also results from 1 . . . 'it>b1 2 'it>b3 'it>a 1 ! 3 l:txb2 - stalemate. But with a

12



How to Study the Endgame

bishop's pawn or a central pawn only the promotion to a knight saves Black. However, with a rook's pawn this idea no longer helps.

1 'it>b4(c4) a2 2 'it>b3 a 1 4J+ 3 'it>c3, and Black is in zugzwang. It is useful to note that if Black also had a pawn on b5, all the same this would not save him: 3 . . . b4+ 4 'it>xb4 4Jc2+ 5 'it>c3 tt:Je3 6 'it>d3 4Jd5 7 .Uh4 'it>b2 8 .Ud4, and the knight, which is separated from the king , is soon lost. 6 l:.h4! (instead of 6 �d3) wins even more quickly: 6 . . . �a2 (6 . . . 4Jd 1 + 7 'it>d2 4Jb2 8 .l:i.b4 'it>a2 9 �c2 'it>a 1 1 0 l:.b8 ; 6 . . . 4Jd5+ 7 �b3 'it>c 1 8 .l:!.c4+ �b 1 9 .Ud4) 7 .l:.a4+ �b 1 8 .Ue4 4Jf5 9 .Ue5 4Jd6 1 0 b3 c1 1 1 .i.:i.c5+ 'it>b 1 1 2 .Ud 5.

It is hopeless to play 1 . . . a2? 2 .l:.b8+ 'it>a3 3 'it>c2 ! a 1 4J+ 4 'itc3 'it>a2 5 .Ub7 with zugzwang. The only way to save the game is 1 ... 'it>b2! 2 .l:!. b8+ (2 .l:.h2+ 'it>b3 ! , but not 2 . . . 'it>b1 ? 3 'it>c3) 2 .. . 'it>c 1 ! 3 .l:ta8 'it>b2 4 'it>d2 a2 5 ktb8+ �a 1 ! . As you see, when learning new ideas one can sometimes repeat material that has been covered earlier (in this case - promo­ tion of the pawn to a knight). An i ntermediate check to gain a tempo

Stalemate We have already examined one very impor­ tant practical instance of stalemate . Here is another example (wh ich , incidentally, consti­ tutes one of the few 'exact' positions that it is useful to memorise). The diagram position a rose in the game Korchnoi-Kengis (Bern 1 996). Black re­ sig ned , after calculating the fol lowing forced variation .

1 . . . a5? does not work i n view of 2 .l:!.h5! - we already know this idea. But 1 . . . 'it>b5? is also bad : 2 W a5 3 'lt>e6 'it>c4 (3 . . . a4 4 'it>d5) 4 .l:ta8 ! 'lt>b4 5 'it>d5 a4 6 'it>d4 'lt>b3 7 'it>d3 a3 8 .l:tb8 + . The only saving move is 1 . . . '1t>c5! , preventing the approach of the enemy king to the pawn. Outflanking

'Shoulder-charge'

The ideas of 'shoulder-charge' and 'out­ flanking' are vividly expressed in a famous study by Richard Reti ( 1 928) .

1 l:!. h2+ 'lt>a3!

By not allowing the enemy king to approach the pawn , Black gains a d raw. It is i ncorrect to play 1 . . .'1t>b 1 ? 2 'lt>b3 a 1 lD+ 3 'lt>c3. Now let us examine a slightly more compli­ cated example.

1 l:td2(d3) 1 ! d 4 2 .l:i.d1 ! 'it> d 5 3 'it>d7 ! , and Black is i n zugzwang: if 3 ... '1t>c4 4 'lt>e6, or 3 . . .'1t>e4 4 'lt>c6. 1 .l:td 1 ? is a mistake : 1 . . . d4 2 'it>d7 (2 'lt>f7 'lt>e4 3 'it>e6 d3) 2 . . . '1t>d5! (Black prevents the outflanking) 3 �c7 'it>c5! (3 . . . '1t>c4? 4 'it>d6! d3 5 'it>e5) , and it is Wh ite who ends up in zugzwang . Let us now turn to positions in which a rook fights against two con nected passed pawns. Mate th reats to the opponent's king If the pawns a re far advanced (two black pawns on the 3rd rank, or one on the 2nd ran k and the other on the 4th ) , then the rook is unable to stop the m . However, sometimes

14

it is possible to save the game, by pursu ing the opponent's king when it is pinned to the edge of the board . B. Horwitz, J. Kling 1 85 1

In this position Herman Fridstein resig ned against Anatoly Luti kov ( Riga 1 954 ) . He considered the variation 1 �xb3 c2 2 l:.b4+ 'it>d5 3 .l:tb5+ 'it>d6 4 .U.b6+ �c7 , but did not notice the saving i ntermediate check 1 .U.b4+ ! . I should mention, i ncidentally, that d ifferent players can single out d ifferent ideas and ru les, depending on their experience and knowledge. I n the above example attention should be paid to the manoeuvre with which the black king escapes from the checks (after 1 l:.xb3? ) . But you can also disregard it, if this idea is a l ready wel l known to you . The best position for the rook i s beh i nd the more advanced pawn

Some of the ideas mentioned operate not only in endings of the g iven type. Thus, for example, the rook should be placed to the rea r of the more advanced pawn in nearly every case, when it is fighting against two con nected passed pawns.

Wh ite's fantastic move fi nds a precise explanation , from the standpoint of typical ideas for such endings. The variations springing from this rather unlikely move (it attacks one solidly de­ fended pawn and allows the immediate advance of the other) are quite simple when we have descried the basic idea: The black pawns are inoffensive: 1) When they occupy squares of the same colour as their bishop, for in that case White 's king can hold them back without difficulty, by occupying the appropriate white square, for example 36 . .f2 37 l:!.d1 e4 38 'it;c2 j)_f4 39 �f 1 and 40 'it>d1. .

It makes sense to also examine endi ngs which are closely linked to those being stud ied . I n the given instance - sharp rook endings, transposing into endings with rook against pawns. In them we encou nter ideas with which we are already familiar. Alekh ine - Bogolj u bow World Championship Match , 1 9th Game, 1 929

Only this paradoxical move , suggested by Utyatsky, leads to a win. It i nvolves the idea of i nterference. For example, if 3 'it>g4 B lack decides matters with 3 . . . .l::t a 5! 4 .l::t c6 'it>a3! 5 .l:r.xg6 b2 6 :b6 l:ta4+ and 7 . . . l:tb4 . 3 .l::tc 6 4 .U.xg6

The black king must be placed in the path of the opponent's king.

And B lack wins easily.

Of cou rse , we will also meet new ideas which operate in sharp rook endings. The most important of them is inteference. We have already encountered it in the analysis of the Ma r6czy-Ta rrasch ending. Now we will examine a far more complicated exam­ ple.

Thanks to the threat of i nterference, B lack forced his opponent into hurrying to give up his rook for the pawn. In the event of the rou­ tine 2 . . . 'it>b1 ? , interference no longer occurs and White can wait until the pawn reaches b 1 . From there, incidental ly, it takes longer for the king to reach the opposite wing.

Thus we should build u p our theory of the endgame in the most econom ical way, by singling out the most generally u sed tech­ n iques and the most i mportant exact posi­ tions. How best to assimilate and consoli­ date this material is a nother matter. Here one cannot get by without a familiarity with additional examples, i ncluding complicated practical endings (such as the one we have just been analysin g ) . It is useful to try and solve a series of tra i n i ng exercises on the given topic. And above all, I recommend that you analyse i ndependently those endings which you happen to encounter. What does an i ndependent analysis of endgame positions g ive us?

Wh ite can now ach ieve a d raw i n various ways. It is useful to examine the resulting variations, since i n this way we will repeat and consolidate our knowledge of endings with rook against pawns. I n the analysis extreme care has to be taken - despite the apparent simplicity, here one can easily go wrong . 1 ) 7 'it>xg6 'it>c2 8 g4 'iti>d3 9 h4 'iti>e4 1 0 h5 h6 �a6+ 12 'iti>h5! with a d raw (shoulder-charge).

1 ) We learn new ideas and methods, expa ndir;�g our system of knowledge, and we refine the i nformation we a l ready have. 2 ) After analysing a large amount of mate­ rial , we have a better u nderstanding of what featu res are typical and i mportant and should therefore be i ncluded i n the 'system' , and which are accidental i n character. As a result we form o u r endgame impressions most clea rly, economical ly, at the same time without om itting anyth ing i mporta nt. 3) It improves our analytical mastery. 4) At times some players gain the impres­ sion that they largely u nderstand the secrets of chess and that to fi nd the best move in the majority of cases is no problem . They only need not to blu nder, and to obta i n the open ings they want. Analysis helps to rid themselves of such ill usions, and shows what an enormous wealth of ideas is sometimes concealed in the seemingly most modest position. It guards against superficial ity, and aids the development of such important traits as precision, accu racy, industriousness, and so o n . 5) A n analysis o f you r own games enables deficiencies i n you r play to be objectively diagnosed .

6) Analysis sometimes leads to interesti ng results, afford ing creative pleasure . Once when I was looking through Chess lnformator, an ending annotated by one of my pupils, Alexey Dreev, caught my eye. Dreev - Moskalenko USSR Young Masters Championsh i p , Lvov 1 985

U nfortunately, this entire variation is a comedy of errors, at the basis of wh ich is Dreev's natura l , but in the g iven instance i ncorrect striving to defi n itely place his rook behind the opponent's passed pawn . After 9 g5 B lack saves the game by 9 . . . l:th 1 ! (the place for the black rook is to the rear of the more advanced pawn ) 1 0 g6 llh5+!

In 1 976 the USSR Championship was held in Moscow. I n the very fi rst round my friend Boris Gulko adjourned his game against grandmaster Tai manov in a complicated rook end ing. Before the resumption h e asked m e to join in the analysis. In order to figure out precisely some very intricate variations, we had to turn to the theory of the rook endgame with f- and h­ pawns. The elementary information a bout these endings, wh ich was given above, was not sufficient for us. However, the necessary positions could not even be found i n books on the endgame, so that we had to sup p lement 'official' theory with our own analyses. Here is a very important key position that we found (see diagram). White's king is cut off on the back rank. Does th is mean that he is bound to lose? It turns

out that the answer is no.

He will be forced to play 6 1 .l:!.h8 (6 1 �f3 is not possible on account of 61 . . . .l:tc1 ! 62 l:!.xh2 l:tc3+ ), and the black king can ad­ vance, bypassing its rook, in order to approach the h-pawn along the first rank. Note that it is the c2-sq uare that the black rook should occu py. If it is on d2 or e2 , the white rook is no longer obl iged to leave the 4th rank (there is the move 'it>f3 ! ) . With the rook on b2 the king's route via the q ueenside around its rook becomes too long . I n other words, the position is one of mutual zugzwang. Wh ite must be given the tu rn to move . 60 . . .

To win, it is sufficient for Black to return with his king to the f-pawn while the enemy rook is tied to the 1 st rank. But how to ach ieve this? If 66 . . . c;t>c4 the opponent repl ies 67 .U.a 1 (67 l:tf1 .l:!.d2 ; 67 'it>f4 l:tf2+ 68 �g 3 l:td2 ), after which it is pointless to play 67 . . .

Before bringing the king back, it is important to place the rook on d2. Then the ma noeu­ vre of the wh ite rook to h6 (by analogy with the variations just considered ) loses its strength - Black again advances his king , and the wh ite rook ca n no longer reach d 1 . The most accu rate is 67 . . . l:ta21 (not i m medi­ ately 67 . . . l:td2 68 l:ta4+ �d5?! 69 l:th4, and it is necessary to sta rt all over aga i n ) 68 l:tb1 lld2 69 �3 (69 l:ta 1 �d5) 69 ... �d5 (th reatening . . .

How to Study the Endgame

Now let us again remember the ending with which we beg a n : Gl igoric-Smyslov. In the note to Wh ite's 3rd move the variation 3 h6 J:la1 ! was analysed .

.Ud 1 + 1 0 'itc6 .Uh 1 ! . With the king on f6 Wh ite does not have the i mporta nt move 1 1 .Ue 7 , and i n the event of 1 1 l::td 7 (or 1 1 'it>b 7) 1 1 . . .'itf5 the black king succeeds, after elimi nating the f4-paw n , in retu rning to g6 in ti me. I I . I M P ROVI N G YO U R TEC H N I Q U E

However, we did not consider the attempt, by playing 4 l:!.g7+ �f6 (the retreat to the 8th rank is hopeless, of cou rse) 5 l:!.c7 , to reach the position which we have just been d is­ cussing . Knowing of the impending danger, Black can avoid it without great d ifficulty the defensive resources are q uite sufficient.

I w i l l now talk about how you c a n improve you r tec h n i cal mastery. For this you need to study problems which a re common to a l l (or to many) types of endings. Problems, such as the enhanced role of the king in the endgame, zugzwa ng (and a very importa nt specific instance of it - mutual zugzwang, and correspond ing sq uares), the advisabil­ ity of this or that exchange, and so on. It is especially i mportant to sense the spirit of the endgame, to develop the optimal mood for playing it, and to understa nd the psychologi­ cal chess laws which apply here. All this is best studied by analysing practical endings, played by g reat masters of the endgame. As an example, let us look at a game by gra n d master Ulf Andersso n .

26 �b3! This u n h u rried manner of play is typical of Andersson . J ust in case he improves the position of his king and awaits a conven ient moment for the fu rther strengthen ing of his position. This is the way to convert an advantage in the endgame - by doing everything possible to restrict the oppo­ nent's possibil ities, and then, without hu rry­ ing, look for new breaches in his defences. To many the rule 'do not hurry' may seem paradoxical, but in fact it is seen in practi­ cally all the endings of games by the great masters of the endgame. Look carefully at the endings of Capablanca and Flohr, and you will see with what slowness, sometimes bordering on tedium, they convert an advan­ tage (Sergey Belavenets). 26 . . .

A player's endgame tech nique is based on a mastery of the whole arsenal of ideas he has accu mulated - from u nderstanding the spirit of the endgame and its most general laws, to minor tech niques which he encounters when studying his own or other players' games. To illustrate this, I will acquaint you with one ending of my own , broken up into elementary components . First we will examine fou r ' i ntermed iate prod ucts', which , incidentally, a re q u ite instructive in themselves . 1 ) It is wel l known that in the endgame the role of logical thinking increases . One must be able to compile plans, outl ine a scheme for arranging the pieces, and so on. A classic example is provided by the following ending. Capablanca - Ragozin Moscow 1 936

c-pawn (after which the b-pawn could become weak) and to control the entire board up to the fifth rank. This is achieved by moving the king to e3 and by placing the rook at c3, the knight at d4, and the pawns at b4 and f4. A fter he has attained such a position, White will be able to advance his queenside pawns.

63 h4 Black resig ned . 2 ) You will have noticed, of cou rse , that when playing the endgame Capablanca twice repeated moves. Here is what Sergey Belavenets writes about this:

53 .U.d3! Take note : Wh ite does not advance his passed pawn , but switches to a n attack on the enemy kingside pawns. This is fu lly in the spirit of an importa nt principle in the conversion of a n adva ntage - the 'principle of two weaknesses' . After creating a second weakness in the opponent's position , by playing against it and then , in case of necessity, again switching the attack to the first weakness, you convert you r adva ntage i n the most methodical way. I n the broad sense of the word , a wea kness i n the opponent's position can be not only a vulnerable pawn or a badly placed piece, but also our own passed pawn, which he is forced to blockade, o r a n invasion square , which he has t o cover. 53

.

.



g5

The repetition of moves in the endgame plays an important role. Disregarding the fact that it gains time for thinking, it can be mentioned that, by repeating moves, the active side acquires certain psychological gains. The defender, whose position is inferior, often cannot withstand it, and he creates a further weakening which eases his opponent 's task. In addition, repeating moves enables the position to be clarified to the maximum extent. We know that some upholders of 'pure ' chess will severely criticise us for this advice. But we cannot refrain from advising players: sometimes repeat moves in the endgame. In the struggle every chance has to be exploited, and there is nothing ugly or unethical in repeating moves.

3) Let us exa m i n e an exa mple from one of my own games. (see diagram)

Wh ite has a n obvious advantage, but for the moment the invasion poi nts a re secu rely defended .

Now, following the example of the Capa­ blanca-Ragozi n ending, Wh ite outlined a scheme for the deployment of his pieces.

The Theory and P ractice of Rook E n d i n gs M a rk Dvoretsky

Oendings which demand the most inten­

f all the types of endings, it is rook

sive study. Why is this?

Fi rstly, they occu r more often than other types. A good half of all the endings that occur in practice are rook endings. Second ly, here there exists a fai rly deta i led theory of positions with a small amount of material (for example, rook and pawn agai nst rook), which may also be repeated in our games. This theory should be mas­ tered . I n other types of endgame the situations with a min imal number of pawns are either qu ite simple, or not very importa nt. This means that there a knowledge of exact positions is hardly ever req uired - it is l i kely that you will never need it. It is sufficient to know the typical ideas and methods. But in the rook endgame you can not get by without studying a considerable n u mber of exact positions. I offer for you r attention one of the sections of rook endgame theory - endings with a pawn on the rook's fi le. As usual , we will begin our analysis with the simplest cases . And in genera l , we will not delve too deeply into theory - we will merely pick out the most important positions and the ideas involved with them. 1) Stronger side's king i n front of the pawn

A d raw is inevitable. The only way to try and free the king from i mprison ment is by playing the rook to b8. But then the black king will stand guard in place of the rook. 1 l::t h 2 'it>d7 2 l::t h 8 �c7 3 .l::i. b 8 �c1 (of cou rse, 3 . . l::t h 1 is also possi ble) 4 �b2 �c3, and White ca n not strengthen his position. .

Let us move the king and rook one file to the rig ht.

shadow' of its wh ite opponent (say, at c3) , or, with t h e black rook on t h e 7th rank - 'in the shadow' of its own rook. We merely mention these ideas, but we will not study the m . Sometimes they a re sufficient for a d raw, sometimes not. Let us add a wh ite pawn on h5. Noth ing has changed . B lack does not pay any attention to it. It is also a d raw with a wh ite pawn on g5. But with a pawn on f5 White wins. After 1 f6+ �f7 ( 1 . . . '1t>xf6 2 :fa+ ; 1 . . . �h7 2 f7) 2 .l:!.h8 Black loses his rook. It is no accident that I have 'chewed over' these elementary cases in deta i l . You should have a very clear impression of them , and should always remember and make use of them when considering more complicated positions. Kha u n i n - Fridman Len ingrad 1 962

This is a standard defensive scheme: Black's rook is beh ind the enemy pawn, and his king is on g7 (or h7). The wh ite rook is tied to the pawn and ca n not move from a8. If 1 'it>b6 , then 1 ... ltb1 + . The king has no shelter from the vertical checks. After d riving it away, the rook retu rns to a 1 . I should mention that other, more com p l i­ cated and less rel iable systems of defence also exist: the black king may hide ' i n the

In the game there followed 1 . . . hxg3 2 hxg3? g4+ ! 3 fxg4, when a d raw was inevitable, since Wh ite was left with a knig ht's pawn (whether one or two is of no particu lar importa nce). He cou l d have won by 2 g7 4 'itc4 �f7 5 'it>b4 .Ua 1 6 'it>b5 l:tb 1 + 7 'itc6 .l:!.a 1 8 'it>b 7 .l:!.b 1 + 9 'it> a 7 'ite7 1 0 l:tb8 �c1 1 1 'it>b7 (but not 1 1 .Ub6? 'itd7) 1 1 . . .l:tb 1 + 1 2 'it>a8 .l:!.a 1 1 3 a 7 , and a situation that is familiar to us arises: the black king does not reach c7 in ti me. I n view of this analysis, Siegbert Ta rrasch considered this position to be won . But later (in 1 924) a saving plan was fou n d . It is based on the fact that the a6-pawn provides the king with a shelter against vertical checks, but not against horizontal checks. The rook must be transferred to f6 . 1 . . . .Uf1 +! 2 'it>e4 .Uf6 ! It is important to attack the pawn , in order

not to release the rook from a8. The resulting position is known in endgame theory as the 'Vancura position' (from the name of its d iscoverer - Joseph Va ncu ra ) . What can Wh ite d o ? If a6-a7 there always follows . . Jla6 (of cou rse, the black king will not move from g7 and h7). If the pawn is defended by the king, there fol lows a series of checks , and then the rook returns to f6 . For example: 3 'it>d5 l:tb6 4 �c5 l:tf6! (the best square for the rook ! ) 5 �b5 .l:!.f5+ ! etc. If in the d iagra m we move the wh ite king to f4 , we obtain a position which was analysed in 1 950 by Pyotr Romanovsky. 1 . . . .l:i.f1 + ? 2 'it>e5 .l:lf6 is now bad because of 3 .l:!.g8+ ! . But all the same there is no other plan - only the switching of the rook to the 6th rank. Therefore let us play 1 . . . l:tc1 ! . If 2 'it>e5 there follows 2 . . .lk6 - and we reach Va ncura's d rawn position . Wh ite must take the oppor­ tun ity to remove his rook from a8: 2 l:tb8 .l:!.a 1 3 .l:r.b6 (weaker is 3 .Ub7+ 'it>f6 4 a7 'it>e6 ). With the rook on a8 Black's king was tied to the kingside, but now it ca n head towards the pawn . But this must be done cautiously: he loses after the hasty 3 . . . �f7? 4 .

This means that the attempt to switch the rook to the 6th ra n k can not be delayed - this plan must be carried out as soon as possible. The system of defence exam ined by us is very important. In particular, th is is how the defence should be a rranged when the opponent has two extra pawns - 'a' and ' h ' .

Strangely enoug h , i n books on the endgame this position is not a nalysed . It had to be stud ied independently. White wins. The main reason is that the black rook does not have the i mportant f6-square , and the 6th ran k proves too short. 4 �5 Again threatening 5 l:Ia7 + . 4. . .

On prophylactic g rounds it makes sense to remove the king beforehand from the first rank: 4 1 'lt>g2 ! ? .

The pawn has to be halted . In the g iven insta nce it is not the rook that is placed behind it, but the q ueen .

' O f course, i t is not essential to give u p the pawn , but from the practical point of view this is the best cou rse. Subsequently you no longer have to think, since you will be acti ng in accordance with theory. Remember: this is h ow Yusu pov acted i n his game agai nst Karpov.

In these last two examples both the moves and the comments made by g randmasters make a comic i mpression , for one simple reason - they were not sufficiently fam i l i a r with the basic theory o f rook endings. Our next step should probably be an analysis of positions that a re closely l i n ked with the type of endgame a l ready stud ied namely, endings in which each side has two or th ree pawns on the kingside and one has an extra passed pawn on the q ueenside (usually a rook's pawn ). Such a situation often occu rs in practice . But th is is a l ready another topic, and here we will merely mention it. I will restrict myself to one example, in which the same idea was used as we saw in the Karpov-Yusupov game, but did not see in the Rachels-Gu revich end ing : the sacrifice of a pawn to transpose into a theoretically d rawn position .

Reckoning that if 1 8 . . . �e6 the reply 1 9 tt:Jc5 was u n pleasant, I wa nted to play 1 8 . . . tt:Jc6. But my sense of da nger operated and I began to have dou bts about the position arising after 1 9 c4 d4 20 tt:Jc5 b6 21 tbd3. Wh ite creates a pawn majority on the queenside, he secu rely blockades the d4pawn , and he controls the e-file. The adva ntage is on his side: perhaps not a g reat advantage, but an enduring one. When I showed this ending to Rafael Vaga n i a n , an expert on the French Defence, he assessed the position as unfavourable for Black. By accu rately defending, one can probably avoid defeat, but this is a d ifficult and than kless task. Being an active player, I usually avoided this type of passive de­ fence , and endeavoured to fi nd a way of sharply changing the cou rse of the play, of forcing events , either with the aim of clarifying the situation, or, on the contra ry, of compl icati ng the play as much as possible. Returning to the rook move to e6, I q u ickly fou n d the forcing variation which occu rred in the game. 18 . . .

I knew for sure that this was a d raw, and a fairly simple one, and so without hesitation I went in for the exchanging combination. Of cou rse , had I not made a previous study of this type of endgame, I would hardly have decided to give up a pawn . Who knows how the game would have ended after 1 8 . . . lt:Jc6 , whereas as it was I easily made a d raw.

Thirty years later I realised that endings of this type were by no means as harmless as I then thought. In 2003 in the theory of rook endings with an extra pawn on the wing a revolution occurred, and positions which had seemed completely drawn proved to be won or at the least very dangerous. You can find these new ideas in my articles or those of grandmaster Carsten Muller in the ar­ chives of the internet site Chesscafe. com, and also in my book Dvoretsky's Endgame Manual from the same publisher. If I had known about the future discoveries, I would perhaps have rejected the combination (in favour of 1 8. . . l:l.e8!? followed by 1 9 . . . 'it>f8), and at the least I would have played the endgame more carefully.

However, my decision to sacrifice a pawn was taken not only on purely chess g rounds - it was i nfluenced , as wel l as the subse­ quent play, by certain extraneous factors . At that time I was teaching in the chess department of the I nstitute of Physical Cu ltu re. We were planning to hold a tou rna­ ment on the Scheveningen system : stu­ dents (candidate masters) against masters, and I had to fi nd some opponents for our students. The Moscow Tea m Champion­ ship, held in the Centra l Chess Club, attracted nearly all the Moscow masters , and this was the most convenient place to hold discussions. After transposing i nto a comparatively simple ending soon after the start of play, I gai ned the opportun ity, by making my moves without much thought, to rush to the other boards and press players who were strolling about to take pa rt in our tou rnament. Because my attention was d ivided , some of my moves were not the most accu rate , but I nevertheless gai ned a d raw. 27 g3 g6 28 e3 �c3+ 31 . . . We6 or 31 . . .

Two ideas , typical of such endings, were clearly seen d u ring the cou rse of the play: 1) th e cutting off of the king along the 4th rank - thanks to this, Black won the game; 2) the 'shoulder-charge' - Wh ite was hoping to save hi mself by employing this device , b u t with an i ntermed iate check Vitaly Tseshkovsky disru pted my plan.

Incidentally, now you will see why on the 46th and 47th moves White replaced his rook at c6 - i n order to free the b6-square for his king. Such 'trifles' sometimes decisively affect the result of the game, and on no account should they be disrega rded .

On the last move before the time control Jan Ti mman makes a decisive m i stake. He thought that he wou l d always be able to advance his pawn to e3, but he d i d not take account of the strong i m peding reply 41 .l:ie5 ! .

58 �b6 Black resigned . The 1998 No.5-6 issue of the magazine Shakhmaty v Rossii published an extensive article by Alexey Kuzmin, in which the grandmaster pointed out a number of mis­ takes in the analysis of the Yusupov­ Timman ending.

This means that there is no reason to criticise his choice on the 38th move.

Initially I thought that the pawn ending arising after 50 ... 'it>d71 51 b7 'it>c7 52 l:.c4+ l:!.xc4 53 'it>xc4 'it>xb7 54 'it>d5 was won i n view o f 54 . . .

to lay a firm foundation: to pick out the most importa nt theoretical positions, ideas and tech niques, which u nderlie our notions of the endgame in question . As a rule, the necessary basic knowledge is made up of a small nu mber of rather simple positions, but they must be understood i n every detail and firmly remembered .

After 1 . . . i.. b 3? the position is lost. First Wh ite gives a verifying check with his bishop, i n order to determine the position of the enemy king . I n so doing it is important

A successfu lly developed system of basic endgame knowledge provides a rel iable guide in the analysis of more complicated situations and helps them to be more successfu lly understood . How this occu rs , I will show using an example of endings with opposite-colou r bishops.

Next the white king makes a by-pass manoeuvre to the aid of the e-pawn, on the opposite side to where the oppo­ nent's king has moved. For exa mple:

Connected passed pawns Let's discuss in detail the followi ng elemen­ tary ending.

After the pawns have reached e6 and f6 , even if the th reat of f6-f7+ is parried , Wh ite repeats the same proced u re : a verifying check with the bishop and a by-pass by the king . It is incorrect to play 2 il.b4 + ? �f7 ! (Black's only hope is to provoke a prematu re e5-e6+ and wedge his king between the pawns) 3 �d4? i.. c2 ! 4 e6+ �f6 5 e7 i.. a 4 with a d raw. As soon as the pawns are blockaded on squares of the same colour as their bishop, the draw becomes obvious.

Thus, with his bishop on b3 Black loses. On the other hand , 1 i.. d 7! 2 i.. g 5+ �f7 1eads to a n easy d raw. Su bseq uently Black waits, movi ng his bishop between c8 and d7. I n order t o prepare e5-e6 , Wh ite wou ld need to make a by-pass with his king from the left, . . .

but this is impossible, since the king is tied to the defence of the f5-pawn. The following ru le suggests itself: the bishop should be positioned such that, while preventing the advance of one pawn, it simultaneously attacks the other.

We will use the ideas from the basic position just examined for an analysis of other positions. First some com paratively simple ones. Let us shift all the pieces one ra nk forward . What has changed?

After a l l , with the king on f8 White's only plan - a by-pass with the king from the right - is impossible: the edge of the board prevents it. But it is Wh ite to move , and he shuts the opponent's king in the corner by 2 .il.. c4 ! and then carries out the standard manoeuvre the by-pass with the king from the left: 'it>h5g4-f5-e6-f7 . After 1 if..f8 ! the by-pass is no longer possible, but what about the threat of zugzwang? I n order to put the opponent in zugzwang, Wh ite must deprive the king of the g8-square by playing 2 if.. c 4. But after 2 .i.xh6! 3 �xh6 things end in stalemate . . . .

In the event of 1 . . . .i.b4 there is no d ifference. Wh ite wins in exactly the same way (a check and a by-pass by the king); moreover, here, as it is easy to see , both checks at b6 and b5 are equally good .

. . .

After 1 .1i.d8 2 if.. g 6+ (or 2 .i.b5+) 2 �f8 3 Wf5 Black loses because of zugzwang - in contrast to the previous position , he no longer has a waiti ng move with his bishop. . . .

(see diagram) The proximity of the edge of the board introduces new featu res i nto the evaluation of the positio n . Let us verify 1 . . . if.. b 2. If Black could also manage to play 2 . . . Wg8 and 3 . . . 'it>f8 , the d raw would become obvious.

The black bishop i s not i n its best position (the place for it is at e7 or dB). In the basic theoretical position , with which we beg a n , agai nst such a bishop Wh ite won easily.

Separated pawns Generally speakin g , the fu rther apart the pawns are, the more d ifficult the defence. When I was young I lea rned a h u morous rule for assessing such endings: if you can reach both pawns with the fingers of one hand , then the position is d rawn ; if you can't (the distance between the pawns is too great) the position is won ! Alas, such a g u ide is too imprecise to be trusted . In fact, here there exist many different situations which it is not at all necessary to study and remember. The outcome usually depends on the possibil ity of a breakthrough by the stronger side's king to the pawn being stopped by the bishop, i n order to queen it. But the fol lowing ending should defin itely be included in our system of basic knowledge.

The wh ite king must not be allowed to reach e 7 - this means that, apart from d7, the black king also has two other squares: e8 and d8.

Endi ngs with many pawns After studying for many years the theory of endings with opposite-colour bishops, I observed several rules which , as it tu rned out, apply in nearly all such endings and g reatly help in confidently fi nding you r way in them.

tion of an impreg nable position , in which it is sufficient to stick to waiting tactics si nce everything is secu rely blockaded and de­ fended . The main theme in endings with oppo­ site-colour bishops is the theme of the fortress. The weaker side aims to con­ struct a fortress, while the stronger side aims to prevent its construction or (if it has already been constructed) find a way of destroying the opponent's defences.

If it is Wh ite to move he saves hi mself by 1 c5! i.. x c 5 2 �b3 e5 3 �e6 'l,;c7 4 'it>e4. Later he s i m ply plays h i s bishop up and down the h3-c8 d iagonal. 1 . Drawi ng tendencies. This i s perhaps the best-known property of endings with opposite-colour bishops. Here it is some­ times possible to save the game when you are 2-3 pawns down (as, for instance , i n the example just exa m i ned ). And remember the endings with two con nected passed pawns - in what other type of endgame may such an enormous material and positional advan­ tage prove insufficient for a win?

The consequences of this rule a re obvio u s : the stronger side should be extremely careful both when transposing into an ending with opposite-colour bishops, and when playing such an ending - here it is easy to run into a drawing counter­ chance. And for the weaker side, trans­ posing into an ending with opposite­ colour bishops is sometimes a last resort here the chances of a draw are sharply improved. -

II. Fortress. A fortress is a system of passive defence, consisti ng in the construe-

I n the textbook example the concl uding position constitutes a fortress. Wh ite does not seek any active cou nterplay, but simply wa its , and the opponent is u nable to do anyth ing. When playing endings, an abil ity to analyse positions logical ly, by th i n king i n plans and schemes, is very important. The role of logical th i n king is especially great in endi ngs with opposite-colour bishops. In the majority of cases they should not be 'played ' , but 'constructed' - fi rst look for the a rrangement of pieces and pawns which makes the position impreg nable, and only then verify by calcu lating variations whether it is possi­ ble to achieve the plan ned set-up and whether it is i ndeed impregnable. The following mech a n i s ms constitute either the most i mportant general methods of constructi ng and destroying a fortress , or featu res of the most typical and freq uently­ occu rring types of fortresses. I l l . Arrangement of the pawns. There is a wel l-known principle which prescribes that pawns should be placed on sq uares of the opposite colour to those on which you r own bishop moves. In endings with opposite­ colou r bishops this principle remains valid for the stronger side (it is especially i mpor­ tant with regard to con nected passed pawns). But, contrary to the general rule, the weaker side should keep his pawns on

From the Simple to the Complicated

squares of the colour of his own bishop

in this case it is usually possible to ensure that they are securely defended . I ndeed , a pawn defended by the bishop can be attacked only by the enemy ki ng, wh ich means that it rema ins invul nerable. In other types of endings such a pawn may be attacked not only by the king, but also by another piece (knight or l i ke-colour bishop).

-

I n the textbook example the weaker side's pawn is on a l ight sq uare - the colour of its own bishop, and this factor ensures the solid ity of the fortress constructed by Wh ite . I n the i n itial position the stronger side, with his da rk-sq uare bishop, has only the one pawn on e6 correctly placed on a lig ht­ square. If Black were able to approach it with his king , he would then play . . . f6-f5 and easily convert his material advantage. The only way to d raw is to force the e-pawn to move onto a sq uare of the colour of its own bishop. IV. Nuances i n the position are more important than material. I n endings with opposite-colour bishops the nu mber of pawns on the board is often of fa r less importa nce even than seemingly insign ificant cha nges in the placing of the pieces or pawns. Therefore in endings with opposite-col­ our bishops, positional pawn sacrifices constantly occur. Thus in the textbook

example Wh ite happily sacrifices a third ( ! ) pawn in order t o achieve a 'trifle' - shift the black e-pawn one step forward .

and stops the two enemy pawns on f6 and g5. But i n the Averba kh position analysed earlier the bishop defends the g6-pawn along one diagonal and restrains the passed a5-pawn along another. Such a situation is u nfavourable for Black. In the solution and the false trail you saw two typical ways of exploiting the defects of a 'torn ' bishop: zugzwang and diversion.

VI.

Pawns ' u nder attack'. A typical defensive procedure is an attack on the opponent's pawns by the bishop. I n thi s

way either they are forced t o move onto less favou rable squares of the colour of their own bishop (as i n the textbook example), or the opponent's king is tied to the defence of the pawns (as in the basic position with two con nected passed pawns or the Berger­ Kolterman ending). Endings very often occur where the stronger side has a passed pawn . It must be blocked by the king (fi rst system of defence) or the bishop (second system of defence). VII. First system of defence - the weaker side's king blocks the opponent's passed pawn , and the bishop defends its own pawns. This is the basic and usually the most rel iable method of defence. Attempts to destroy the first system of defence always involve creating a sec­ ond passed pawn, often by means of a pawn breakthrough.

We wil l now do some tra i n i n g i n the employment of this theoretical foundation for the analysis of specific endings. We wi l l try t o approach them in a logical way: w e will point out which system of defence has been employed or should have been employed by the weaker side and i n what way it may be possible to try and destroy this fortress, whether the pawns a re correctly placed , whethe r it isn't possible to put the oppo­ nent's pawns ' u nder attack' , whether, in order to carry out some idea, it is possible to sacrifice a pawn or two , and so o n .

I n fact the position is, of cou rse , d rawn - this is clear at first glance, it being sufficient only to remember the d raw­ ing tendencies with opposite-colour bish­ ops. How can one explain such a bad mistake in eva luation , made by a player who at one time was q u ite a strong g randmaster? I n my view, by a change of professio n : one by no mea ns fi ne day Krog ius decided to ' re­ qual ify as a manager' , first in his native Saratov, and then in Moscow - he became head (and, it should be mentioned , a very nasty head ) of the Chess Ad ministration of the U S S R Sports Committee .

Vakhidov - Timoshchenko Tashkent 1 982

It appears that White is out of danger - his bishop has defended his pawns, and his king is blocking the opponent's passed pawn . But the bishop is really very passive ­ soon it will not have a single waiting move. If the king can also be deprived of its mobility, a zugzwang situation could result. This aim, strangely enoug h , is q u ite ach ievable: the wh ite king is g radually pushed to b3 and the black king will occupy the d 3-square , from where it conti nues to tied down the oppo­ nent's bishop and at the same time th reat­ ens to support its passed pawn . But if the pawn were slig htly fu rther away - on the a­ file - a d raw would become inevitable. 5 ..td1 'it>g3 6 �f3 'it>f2 7 'it>c2 b4 8 �b3 ..tc3 9 �c4 h6 1 0 �d3 ..te1 1 1 �c4 ..td2 12 �d3 �c3 (zugzwan g ! ) 1 3 �c4 �e3 (again zugzwan g ! ) . If 1 4 � b 3 , t h e n 1 4 . . . �d3 (the decisive zugzwang ! ) 1 5 �a2(a4) �c2 and wins. The game went 14 'it>d5 b3 and Wh ite resigned .

For the moment Black is not threatening to play 1 . . . g3 in view of 2 g5! and 3 �g8 - he is plan ning 1 . . . g5! and only then 2 . . . �g3. Now White has to decide how he will defend his kingside pawns and which piece will hold back the enemy passed pawn on the queenside. In the game he chose the fi rst system of defence: he switched his bishop to the defence of his pawns, and kept his king on the queenside. 1 .i.b3 g5! 2 .i.d1 2 h4 gxh4 3 g5 does not work: 3 . . . �g3! (but not 3 . . . 'it>xg5? 4 .i.e6 f4 5 .i.f5 'it>g3 6 .i.h3 with a draw) 4 ..tg8 'it>xg2 5 ..txh7 ..tc5 ! , and Black wins. 2 ... a6 3 ..tf3 b5 4 axb5 axb5

Now let us try to set up the second system of defence - use the king for the defence of the kingside. But this plan too is not altogether rel iable - after a l l , the bishop will have to perform two tasks: not only conta i n the enemy passed pawn , but also defend its own e4-pawn , and along a d ifferent d iago­ n a l . This means that here too a zugzwang position is q u ite l i kely. 1 ..td5 g5! 2 'it>e2 h6 3 ..tb7 ..tc5 4 ..td5 a6 5 ..tc4 (5 ..tb7 b5 6 a5 b4 7 ..txa6 �xe4 is no better) 5 . . . b5! 6 axb5 a5 (Black happily sacrifices a pawn for the sake of creating a passed pawn ) 7 ..td5 a4 8 ..tc6 a3 9 ..td5 ..tb6. Zugzwa ng! The wh ite bishop has no moves, si nce it is 'torn ' between two d iagonals. I n the event of 1 0 Wf1 (e 1 ) 'it>e3 the black king breaks through to its passed pawn , while if 1 0 'it>d 3 , then 1 0 . . .

Is the initial position really lost for Wh ite? Let's use our knowledge of opposite-colour bishops to guess where a saving line might nevertheless be concealed .

The d raw is obvious, since now the bishop easily copes with the defence of the king side. White's moves can be transposed : 1 �g8 h6 2 g5!! �xg5 3 iLf7 .

First of all one should usually check the basic system of defence - the fi rst. But how to securely defend the kingside with the bishop, and prevent there the creation of a second passed pawn? The ma noeuvre of the bishop to f3 solves this problem , but it inevitably leads to zugzwa ng. I s there no other way? Remember the procedu re ' pawns under attack' and for the sake of implement-

It is not possible to prevent the advance of the pawns to the 5th ra nk (for this the bishop would have to be switched to c6) . But how should the black pieces be deployed agai nst pawns on the 5th ra nk? Obviously, bishop on f7(g8) and king on d7. It is this set-up that must be prepa red . 1 .. .

The typical plan is to march the king to the pawn which is being stopped by the bishop, i.e. to f8 . But then Black will advance his a­ pawn , d iverti ng the bishop from the defence of the c7 -pawn. The only winning chance is to switch the bishop to a5, from where on the same a5-d8 diagonal it will defend its own pawn and stop the opponent's. But fi rst the c7-pawn must

be defended with the king, without allowing . . . a7-a5-a4 . If the black pawn should reach a4, the position will become d rawn , for example: 1 �c5? a5! 2 �b5 a4 3 �b4 �c8 . 1 �c3 !

4. Nimzowitsch-Tarrasch (Kissingen 1 928). Black must decide how to combat the threatened attack by the king on his kingside pawns.

Fi rst let us see what happened in the game. 39 ... c4? Moving the pawn onto a sq uare of the colour of its own bishop is, in genera l , a sound

positional idea (imagine that Wh ite were to play c2-c4 , b2-b3 and a2-a4 - then the b6· pawn would be transformed into a serious weakness). The move made by Black is not bad in itself, but for the reason that it does not help to solve the main problem of the position - the defence of the kingside pawns. 40 'it>g3 �c8 41 'it>f4 'it>d7 42 j;_b4 �e6 43 Jl.. c 3 Ji.. d 7 If Black keeps his bishop at g6 and uses his king to stop the futu re passed pawn on the q ueenside (first system of defence), at an appropriate moment Wh ite will attack the bishop by h3-h4-h5 and obta i n a second passed pawn. For example, 43 . . . ii.g6 44 g5 �d5 45 g3 b5 46 h4 �c6 4 7 b3 cxb3 48 cxb3 'it>b6 49 a4 bxa4 50 bxa4 'it>a6 51 a5 �b5 52 h5 ii.e8 53 �xf5 ii.xh5 54 �xe4 with an easy wi n . Therefore Black leaves his bishop on the queenside. U nfortunately for h i m , his king can not simultaneously defend the h7- and f5-pawns, and therefore his bishop will be 'torn' between the defence of the f5-pawn and the struggle agai nst the opponent's passed pawn . 44 g3 b5 45 �g5 �f7 46 h4 Jl.. c 8 47 �h6 �g8 48 b3 cxb3 49 cxb3 f4 This is already desperation in a hopeless position.

The Arith meti c of Pawn E n d i ngs A rapid eval uation rule

Ppawns and an outside passed pawn for ositions with a pair of blocked rooks'

one of the sides occu r qu ite often in practice. Therefore it is usefu l to be able to evaluate them quickly and accu rately. The winning plan is obvious: march the king over to the rook's pawn . The opponent has to elimi nate the pawn on the other wing and then rush with his king to the corner, in order to stop the rook's pawn . I n which cases does he manage to do this? It is easy to see that the position has become d rawn : 1 '>t>d5 'iM6 2 'it>c5 'it>xf5 3 'it>b5 '>t>e6 4 'it>xa5 'it>d7 5 'lt>b6 '>t>c8. If, say, the kings and the f-pawn are sh ifted one rank down or to the left, Black again loses . But what happens if the queenside pawns a re also sh ifted down?

Here White wins: 1 'it>d5 'it>f6 2 'it>c6 'it>xf5 3 'it>b6 'it>e6 4 'it>xa6 'it>d7 5 'it>b 7. Now let us shift the queenside pawns back by one rank.

Of course, if you have the position in front of you , it is easy to g ive an answer to any such q uestion . But i n practice such situations often a rise at the end of lengthy variations, which you have to calculate , and to lengthen the calculation by several more moves may prove d ifficult. It would be desirable to learn to determ ine the evaluation of the position i mmed iately, on first looking at it. A simple method of rapid evaluation was suggested by Walther Bahr in 1 936. To me this ru le seems not altogether conven ient, and besides it does not extend to cases where the king is not to the side of the passed pawn , but in front of it. I n con nection with th is I should l i ke to offer a somewhat

lLJ

The Arithmetic of Pawn Endings

83

different method of rapidly evaluating such positions. 1 ) The first rule coincides with Bahr's analogous ru le: if the rook's pawn of the stronger side has crossed the middle of the board, the position is always won. It

follows that from a single glance at the first diagram it may be concluded that the position is won . 2 ) We will call the position i n the second diagram 'norma l ' . This is what makes it such :

a) between the queenside pawns there passes the i nvisible demarcation line, sepa­ rating the u pper and lower halves of the board ; b) the black king , which is aiming for the c8square, reaches there without loss of ti me. This happens because the passed pawn has already crossed the key h3-c8 d iago­ nal , or is on this diagona l . A

With Wh ite to move , it is a w i n : 1 a5! (the pawn has crossed the middle of the board ) . With Black t o move , i t is a d raw: 1 . a5! , a n d a 'normal' position a rises. . .

'normal' position is drawn.

3) Each sh ifting of the kingside pawn one square down from the h 3-c8 d iagonal is equivalent to a tem po i n favou r of White. For example, the pawn on f4 g ives one tempo in favour of Wh ite , and the pawn on e4 g ives two. One fu rther tempo for the stronger side may be given by having his king not to the side of the passed pawn, but in front of it. But each shifting of the q ueenside pawns one square down compared with the 'nor­ mal' position g ives the defending side a tempo. With the pawns on a3/a4 Black has one tempo in his favou r, and with the pawns on a2/a3 he has two . White wins only if the sum of tempi, calculated in this way, is in his favour.

The formulation suggested by me looks rather complicated and cu m bersome, but if you learn it thoroughly you will find it very easy to use.

Wh ite wins: he has two tempi (the g2-pawn is two squares lower than the g4-sq uare), while Black has only one. But if the queenside pawns a re sh ifted down one ran k , the score becomes 2-2 and the position is now d rawn .

The Arithmetic of Pawn Endings

Accord ing to the afore-mentioned rule, this should be a d raw. And i ndeed : after 1 . . �5 2 'ith5 (2 'itg3 'itg5 - a 'normal' position) B lack does not play 2 . . . 'iii>f6? 3 'itg4 , when Wh ite acq u i res an extra tempo, since his king is in front of the pawn , but 2 . . .'itf4! 3 h4 (3 'itg6 'itg3) 3 . . . 'itf5 4 'ith6 'itf6 5 �h7 'itm(f5) 6 h5 'itt6 ! etc. .

N ow let us examine some more complicated endings, i n which a mastery of the rule suggested by me sign ificantly eases the calculation of variations. Here, of cou rse , it is White to move (with Black to move he has to concede the opposition and Wh ite can queen his f-pawn ) . Wh ite wins, since t h e score is 3-2 in his favour (two tempi a re g iven by the pawn on f3 and another one by the position of the king in front of the pawn ). He wins by 1 'ite4! 'ite6 2 'itd4(d3). It would be a blu nder to play 1 'ite3? 'ite5(f5), since then a position with a tempo ratio 2-2 is reached (the wh ite king is no longer in front of the pawn , but to the side of it), and this means a d raw.

One more useful deta i l . Let us suppose that White's passed pawn is a rook's pawn , and his king is in front of it, but the enemy king is confining its opponent to the h-file. This situation is equivalent to the one in which the king is to the side of the pawn.

Black's positional adva ntage is obvious. His plan is clear: . . . 'itg6-f5-e4 and then an attack by his bishop or king on the q ueenside pawns. This plan can be prevented by offering an exchange of bishops, but this demands precise calculation . 1 ..td4!

If White does not evaluate them ' mechani­ cally' , by using the rule g iven above , but tries to work out the variations to the end, he each time has to calculate some ten more moves, and this is not at all easy. The players in the fol lowing ending faced even more complicated problems.

In his notes Mikhail Botvinnik analyses two cou rses of action for Wh ite : 43 .l:td5 and 43 l::td 6+ 'it>e7 44 l:f.a6. In fact there is also a third : 43 'it>f2 ! , for example, 43 . . . exd3 44 'it>e3 l::.a 1 (44 . . . .l::!. g 1 45 'it>f2 ) 45 l::.x d3 .l::i. x a4 46 l:td6+ followed by 47 l::. a 6, and Wh ite should gain a d raw. But let's forget about this possibil ity and try to choose the more accu rate of the two possible rook moves. First, after analysing some short variations, we must try to disclose the d ifference between them, and compa re their virtues and d rawbacks . I n the event of 43 .l:td6+ 'it>e7 44 .l::i. a 6 a clear d raw resu lts from 44 .. J1xd3 45 .l::i. x a5 or 44 . . . .l:!.d2+ 45 lt:Jf2 e3 46 'it>f3 !

N ow 46 'it>f2? is bad in view of 46 .. J1g 1 !; Wh ite is forced to play 46 .l:!.a8 , allowing the black king to approach its passed d-pawn . I s this rook ending lost or d rawn? You can't say i m medi­ ately, and this means it is time to cut short the calculation and switch to a verification of the alternative possibil ity.

Things are difficult for Wh ite : noth ing is g iven by 3 .l:i.h6+ l:i.g6, and so he is forced to play 3 l:th3, but here the rook is exceptionally passive . But here Boris Zlotnik unexpectedly made a move which I had overlooked in my analysis. 2 'it>b2 The idea is clear - to avoid the capture of the g3-pawn with check.

The adjourned position ; it is my move . The national master Anatoly Donchenko sug­ gested an excellent idea for Black. Usually with an advantage you are recommended to avoid pawn exchanges, but this is an exception to the rule. 1 .. .

The move is an interesting one, and during the game it seemed to me to be very stro n g . B u t after a thorough analysis I began to have doubts about its strength . The point is that when Black elimi nates the g-pawn and obtains a position with con nected passed pawns, the basic method of defence is to try and wedge the king between the pawns a n d blockade the m . B u t here the king , in solvi n g a pa rtial problem (i nvolving t h e g3-pawn ), volu ntarily moves away from the queenside pawns. 2. . . 3 �xh3

My opponent was the national master Zlotn ik, a chess teacher in the I nstitute of Physical Cultu re. I g reatly respected h i m , and t o me he w a s a n expert. When you play such a person , a defi n ite complex appears , you beg in t o fea r everyth i n g , and therefore i t can b e d ifficult t o make an active move. Besides, I did not consider that the position was one where every tempo cou nted , I thought my king would always be able to go over and captu re the g4-pawn , and for the moment it would not be bad to help the queenside pawns . What would have happened after 6 . . . rJ;e5 ? Let us try to provoke the advance of one of the pawns: 7 l:!.a8 . Black replies 7 . . . a4 , and if 8 �a3(c3), then simply 8 . . . .l:txg4. The king has not managed to reach b4 and after 9 l1b8 l1g3+ 1 0 �a2 .l:!.b3 Black wins. If 8 �b8 (instead of 8 �a3 ) , then 8 . . . �d4 9 �a3 �c5 1 0 lk8+ �b6 1 1 llb8+ �c6 1 2 lk8+ �b7 and 1 3 . . . I:txg4 with a wi n . The fact that his king is cut off along the 6th rank does not concern Black - his rook will free the king by . . . l:tc4-c6 . Thus, 6 . . . 'it>e5 was a very good move, but I played differently. 7 l:tc1 Wh ite wants to place his rook behind his passed pawn . �d 6 ?

7 . . . 7 . . . �d5 was far stronger. Now the captu re of the pawn leads to a typical drawn position with connected passed pawns, one which occu rs q u ite often : 6 . . . .!::!.xg4? 7 .l:!.c6+ rJ; e7 8 .l:!.c5 l:tb4+ 9 'itta 3 a2 . Black cannot strengthen his position , since his king has n o shelter from the side checks.

8 .l:f.g 1 I should l i ke t o dwell on this position in more deta i l . (see diagram)

Wh ite has succeeded in sign ificantly activat­ ing his rook. If his pawn were on g 5 , he would u ndoubtedly be able to d raw. B ut with the pawn on g4 his rook has not so many squares for manoeuvri n g . Black now has two plans for playing for a w i n :

Typical Endings with Connected Passed Pawns

1 ) play his king to the help of the queenside pawns; 2) first captu re the g4-pawn with the king, and only then return to the queenside. We will first examine the simpler plan, involving 8 ... 'it>c5. It is obvious that if Black can place his pawns on a4 and b4 he will win easily. Therefore White's objective is to hinder the advance of the pawns, l u re the rook away from g5 as soon as possible and begin advancing his passed pawn . First let us analyse 9 Wb3 . If 9 . . . b4 (with the threat of 1 O . 'i!i>b5) there follows 1 0 'it>a4 'it>b6 1 1 .l:!.f1 .l:!.xg4 1 2 .l:!.f5 ! with an i m mediate draw. .

.

Let us verify 9 . . . a4+ 1 0 'it>a3 'it>b6! 1 1 'it>b4 (preventing 1 1 . . . 'it>a5) 1 1 .. Jie5 ! . Against the threat of 1 2 . . . l:te3 Wh ite has two defences: 12 l:tg3 and 12 'it>c3 ( 12 'it>a3 .l:te2 is unsu itable, since the king remains in a mating net). After 1 2 .l:!.g3 .l:!.e4+ 1 3 'i!i>a3 'i!i>a5 (with the th reat of 14 . . . .l:!.e2 ) 14 'i!i>b2(a2) b4 the black pawns reach their goal sooner than the g­ pawn . No better is 1 3 'i!i>c3 b4+ 14 'it>d3 a3! 1 5 'it>c2 .l:!.e2+ etc. Let us examine 1 2 'i!i>c3. Here the win for Black is not obvious.

I n lessons devoted to the tech nique of converti ng an advantage, an important principle has been mentioned : to make use of any opportun ity to improve even slightly you r own position and weaken the oppo­ nent's. Here Black can move his king forward , but in this case the wh ite pawn advances and there is no longer a win. The only way to the goal is to interpose the check 1 2 . . . .l:!.c5+ ! . If 1 3 Wb2, then 1 3 . . . .l:!.g5, and the b-pawn advances to the 4th rank. I n the event of 1 3 'it>d4 Black can either advance his pawn i m med iately, or fi rst play 1 3 . . . .l:!.g5. There only remains 13 Wb4 l:tc4+ 1 4 'it>a3 . The d i rect 1 4 . . .a5? does not achieve anyth ing: 1 5 'i!i>a2 b4 1 6 g5 b3+ 1 7 'it>a 1 ! a3 1 8 g6 b2+ (for 1 8 . . . a2 and . . . 'i!i>b4-a3 Black is just one tem po short) 1 9 'i!i>b 1 Wb4 20 g7 'it>b3 2 1 .l:!.g3+ 'i!i>b4 22 .l:!.g 1 . The correct move is 1 4 . . . .l:!.c2 ! (with the th reat of 1 5 . . . 'it>a5) 1 5 'it>b4 .l:!.b2+ ! (nothing is g iven by 1 5 . . . l:tf2 1 6 'it>c3 ; fi rst the position of the wh ite king must be clarified ), and 1 6 Wa3 l:tf2 1 7 Wb4 .l:!.f3 is bad for Wh ite , while after 1 6 Wc3 there follows 1 6 . . . a3 1 7 g5 b4+ 1 8 Wc4 a2 1 9 lla1 ( 1 9 g6 .l:!. b 1 ) 1 9 . . . b3 20 g6 l::t b 1 2 1 g7.

As you see , the win is very compl icated . Besides, Wh ite's defence can be improved at the very start of the variation . I nstead of 9 Wb3?! we can play more cu n n i ngly - 9 Wa3 ! , so that the pawn should move to a4 without check. 21 .l:i.xa1 22 g8 'ii' .l:tc1 + 23 'it>xb3 a 1 "i'i. . . .

[Nowadays, for the analysis of both opening and endgame positions, increasing use is made of computers.

You see , the king has nevertheless reached e5, but instead of going there immed iately it has wasted time, by wandering about on the e6- and d6-squares. 9 'it>b3

But how should my opponent have de­ fended? Let us assume that we do not know the theory of endings with such a pawn a rrangement - let us try acting simply by using common sense .

White intends by Ua 1 to force the advance of one of the pawns, and then to establish his king between the m . 'it>f4 9. . . 1 0 Ita 1

Let us ask the q uestio n : 'What does Black want?' U ndoubtedly, to take his king to b2, after which it will be possible to give up the b5-pawn and queen the a-pawn . Let's try and hinder the movement of the king, by cutting it off along a file. 12 .l:!.f1 .l:!.f5 1 3 .l::!. e 1 'it>f4 1 4 1:te2 .l:!.e5 1 5 1:td2 �e3 1 6 ltd 1 .l:t.g5 1 7 .l:!.d8 �e4 1 8 .:td 1 1:tf5. It is important not to place the rook on e5 then a check on e 1 will d rive the king away. 1 8 . . . l:td5 is prematu re in view of 1 9 Ite 1 + . Black must play for zugzwang. The white king on b4 is ideally placed , so the position of rook must be improved . 1 9 �d2 Itd5 20 .Uc2 (now 20 11e2+ 'it>d3 is hopeless for White) 20 . . . 'it>d3 2 1 .l:tc8 (21 l1h2 is also not bad ) 2 1 ... 'it>d2 22 l:tc7 'it>d 1 . (see next diagram)

Here I did not bother to ponder over which pawn to advance , and this was a mistake one pawn move leads to a win , and the other to a draw. Let us first see what happened in the game.

U p to this point Wh ite has not been in any particu lar danger, and he could have de­ fended in various ways . But here he must make an accu rate move (23 .:tc3 or 23 l:f.h8), since Black has created the concrete threat

(it is important to control the a3-square) 3 . . . �b2 . At first sight Wh ite is i n trouble ­ Black intends 4 . . . .l:1d4+ and 5 . . . a3. But let us verify: 4 .l:.g3 l:td4+ 5 �c5 ! (5 �xb5? a3 6 .l:.g2+ �c3 7 .l:.g3+ .l:ld 3 ) . If the rook goes to e4 , it is now possible to captu re the b5-pawn and after 6 . . . a3 to begi n side checks. The king has to step onto the d-file, but then the rook attacks the a-pawn and this leads to a d raw. This was Kasparian's conclusion.

23 l:.d2 . For example, 23 'R.c7? l:td2 24 l:.c3 (24 �xb5 a3 25 �b4 a2 26 l:ta7 �c1 ) 24 . . .U.b2+ 25 �a3 .l:. b 1 . After 26 l:th3 there follows 26 . . . �c2 with the threat of 27 . . . .l:.b3+, while if 26 l:tc8 , then 26 . . . �d2 , and the king approaches the pawns. It has acq u i red an excellent shelter from the side checks at a5. This is one of the i mportant winning posi­ tions. . . .

.

And now - the main d rawn position , which it is also essential to know.

H. Kasparian

I n this position I d iscovered another curious subtlety: B lack can try 5 . . . :1d 1 ! . Again it is not possible to captu re on b5, and 6 �b4 is necessary, but then there follows 6 . . . l:. b 1 . Now it is essential to take the pawn: 7 �xb5! a3 8 �a4 a2 9 l:tg2+ , and the king is deprived of the important b 1 -square - d raw! [ There is another way to draw: 6 .l:t g2 + �b 1 7 1:tg3 or 6 . . . � c3 7 �xb5 a3 8 � a4 Dvoretsky.) Let us retu rn to the position after Wh ite's 1 Oth move. We have seen that 1 O . . . a4+? leads to a d raw. Let us now analyse 1 O . . . b4! 1 1 �a4 ( 1 1 'R.g 1 .l:.x:g4 is hopeless) 1 1 . . . � x g4. This pawn configuration is obviously stronger than a4-b5, since after the sacrifice of the a5-pawn the remaining b-pawn is more da ngerous than the a-pawn , and affords more wi n n i ng possibil ities. For the moment the black king is free to approach the q ueenside ( 1 2 .l:.f1 1:tf5 etc. ) . Let us see what methods of defence Wh ite has agai nst pawns on b4 and a5. The first: playi ng for stalemate. (see diagram)

Could we have reached this position? Quite possibly. Wh ite could always have placed his rook on the 3rd rank. The only plan to play for a win is 1 . . . �c2 2 l:th2+ l:td2 3 l:th3!

If the black king goes to c3 , there follows llc2 + ! . But this mechanism is easily de­ stroyed - playing the black rook to the 2nd rank proves decisive.

The second: the attempt by Wh ite to place his own king in the way.

What is the simplest way to win here? Let's improve the position of the rook: 1 . . . l:!.e5. The threat is 2 . . . .l:.e3+ , lifting the blockade of the pawns . Both 2 l:.d 1 + 'it>c5 3 'it>a4 .l:!.e3 and 2 'it>a4 'it>d3 (not i m mediately 2 . . J:te3? 3 'it>xa5 b3 4 'it>b4) 3 .l:tc8 (or 3 'it>b3) 3 . . . 1:!.e3 4 l:.c7 'it>d2 a re hopeless for Wh ite. You see that the key sq uare for the king in this type of ending is d4 - it is very i mportant to occupy it! And after this - accord ing to ci rcum· stances : if the wh ite king is at a4, the route . . . 'it>d4-c3-b2(c2 ) becomes possible. With the king on b3 it comes under check and the black king can then go to c5 and b5. It all seems to be very simple, but look at the following position:

The drawback to the position of the king on b3 is that it comes u nder check along the 3rd rank. 1 . . . 'it>d4 2 1:!.a2 l:te3+ 3 'it>a4 (forced) 3 .. .'�c3, or 2 l:!.a4 l:!.e3+ 3 'it>b2 'it>c4! 4 .l:.xa5 l:!.e2+, and a won position, well known in theory, is reached . Black wins in roughly the same way with the enemy rook on a8 (instead of a 1 ) : 1 . . . 'it>d4 with the idea of . . . .Ue3+ .

The third : t o cut off the black k i n g along the file.

What is the eval uation? Draw! The king

cannot break th rough anywhere. We arrive at a general ru le for this type of ending: I f the black king is cut off i n its own half of the board , the position is d rawn ; -

- But if it breaks th rough into the opponent's ha l f of the board , the position becomes won . A general conclusion for this type o f ending also suggests itself:

ltJ

95

The nu m ber of mistakes that the two players made in this endgame! The reason was an inadequate knowledge of the theory of rook endings. They had no ' beacons' by which they could be g u ided . Thus in the game the moving of the king to the kingside (alas, rather belatedly) should have led to a d raw. Then I again retu rned to the position after 8 . . . 'it>c5 9 'lt>a3.

Black's plan of moving his king towards the white pawn and captu ri ng it leads to a wi n , whereas the plan o f playing the king to the help of the queenside pawns only d raws.

However, later analysis sometimes intro­ duces serious corrections into seemingly establ ished conclusions. On one occasion I looked more carefully at the position after 8.. .�e5.

We have seriously stud ied only 9 . . . a4 , but there is also another idea : 9 ... b4+ ! 10 �a4 l':!.d5! . The th reat is 1 1 . . .�d3. There is no point in retu rn ing with the king : 1 1 �b3 �b5 (with the th reat of 1 2 .. J:td2 ), and Wh ite loses. In the event of 1 1 .U.c1 + �b6 1 2 l:tf1 l:td3 1 3 l:tf6+ �c5 1 4 l:tf5+ �c4 1 5 �xa5 ( 1 5 l:tf4+ l:td4 and 1 6 . . . l:txg4) 1 5 . . . b3 Black wins, since his passed pawn advances more q u ickly than the opponent's, and also it is supported by the king . Why did White play 9 �b3 ? The im mediate 9 J:ia1 ! was far more logica l . N ow the reply . . . b5-b4 is no longer possi ble, and after 9 . a4 1 0 'lt>a3 (not 1 0 �c3 .l:!.xg4 1 1 .l:!.b 1 l:ic4+ ) Wh ite need not fear 1 O . . . l:!.xg4 1 1 .l:!.b1 with an immediate d raw. Black replies 1 0. . .'it>d5 , but 11 'it>b4 �c6 1 2 l:Lg1 leads to an already familiar d rawn position .

Let us verify 1 1 �xa5 l':!.d3 1 2 �a6 (otherwise mate ; 1 2 l:!.c1 + l::tc 3 is bad for White ) 1 2 . . . b3 1 3 g5 .

I n this way the mobil ity of the wh ite king is restricted - now it can neither approach the b-pawn , nor move to the kingside.

Thus our i n itial concl usion has been re­ versed : the plan of moving to the help of our pawns proves to be stronger than the march of the king to the g4-pawn .

On the even ing before the adjournment day our leader Vasily S myslov adjou rned his game against Mikhail Tal in what was a dangerous position for h i m . At a tea m meeting he said that the fol lowing day he would need help with the analysis. ' O f course, of cou rse, let's look at the

it is flattering to have the reputation of being a good ana lyst, a lthough at times it is slig htly onerous - after all, my game was also adjourned . But the fol lowing morning Smyslov and I sat down to look at

his position. After three hours of exception­ ally i ntensive work my head was l iterally spl ittin g , but on the other hand it appeared that we had found a way to save the game. Tal

Even in such sharp endings, where every­ thing can depend on a single tempo, someti mes it is not worth immed iately delving into the mass of variations. You should first logically weigh up the situation and look for a plan, a general idea , which should be carried out. What, do you think, is this idea? It turns out that Black should switch his rook to the 8th ra nk. Fi rstly, from here it covers the king - to checkmate it the opponent will have to bring forward his king and both pawns, and this demands time. Secondly, it may be possible to place the rook behind its own pawn and advance it, while giving u p the other. So, the general plan has been fou n d . It is merely necessary to firid the most accu rate way of implementing it. 43 . . .

But on the other hand the main plan of defence a lso seemed sufficient for a d raw, so that it was not easy for Smyslov to make a choice .

This was how we intended to switch the rook to the 8th rank. True, in this way the position of the wh ite king is improved , although the e5-pawn remains invul nerable. We rejected 47 .

hen I saw t h e analyses b y Artu r in the previous chapter I was reminded of several stud ies on the same theme , which i n their time made a strong impression on me. I hope that they will also appeal to you . Their beauty l ies in the unusual amount of work carried out by the wh ite knight, the paradoxical manoeu­ vres of the wh ite pieces, and above all the precision and depth of logic behind these manoeuvres. Before enjoying the solutions, try to fi nd the answers you rself. I should warn you before­ hand: the problems are very difficult, and you will most probably have to move the pieces on the board (perhaps only the second example might be solved i n you r head ). But even so, don't b e i n a h u rry to make moves - first reason to you rself about the fi nal and i ntermed iate aims of both sides, the plans they will carry out, any important intermediate positions, and so o n .

A knight can stop a rook's pawn, if it succeeds in 'touching' any square in its path (apart from the corner square h1). In the g iven i n stance it is clear that the knight will aim for the h2-sq uare . H ow to reach it­ seeing as the black king stands in its way?

Here are some logical considerations, which will make it easier to fi nd the solutio n . The knight can reach h2 via g4 or f1 . Each of these routes can be control led sepa rately by the black ki n g . It is necessary to create a 'double attack' - by th reatening to go to h2 by both ways . The knight ca n reach f1 via d 2 , and g4 via e5. Do you see the i ntersection point of these two routes? 1 tt'lb4!

Black will try to prevent it by attach ing h i s king to the e2-pawn from d2 or d 1 . It is easy to imagine that here too mutual zugzwa ng positions ca n n ot be avoided .

From this the fol lowing conclusions can be drawn : if Wh ite plays We 1 , then with the knight on d3 Black must reply . . .

6 . . . 'it>b 1 ? loses i m mediately to 7 lt:Jc7 �b2 8 lt:Jb5.

The followi ng step i n our logical a nalysis of the position is to clarify the importance of the e4-square for the knight. Let us su ppose that the knight stands on e4 , the wh ite king on d 1 , and the black king on b3. Then if it is White to move 1 �c1 ! is decisive. But things are no easier for Black if it is him to move : if 1...Wb2 there follows 2 tt:Jc5 !

Here 7 . . . 'it>c4 8 'it>c2 is now pointless.

Thus the knight m ust be brought to the e4square. This is not at all easy to ach ieve , seeing as Wh ite consta ntly has to watch out for . . . d4-d3 . 1lLle1

Converti ng a n Advantage

C ments . One of the most common and

hess players suffer from many ail­

serious is poor tech n ique i n the conversion of an advantage. Even champions some­ times suffer from th is ill ness - it is sufficient to remember the 1990 match for the world championship between Garry Kasparov and Anatoly Karpov. How frequently after an unsuccessfu l game do we state with vexation to o ur opponent, trainer, or a casual spectator: 'I had a completely won position ! ' But it is poi ntless complaining about fate - it is better to th i n k about the causes o f t h e mistakes made, a n d endeavour t o understand what playing o r personal deficiencies are behind you r er­ rors. I will now dwell briefly on the main factors which h i nder the normal conversion of an existi ng adva ntage .

It was only for this reaso n , for example, that he did not win his Candidates semi-final match in 1989 agai nst Karpov. Yusu pov constantly outplayed his form idable opponent, but was u nable to convert this i nto wins on account of tired ness towards the end of a game. Here is one of the most a n noying examples. Karpov- Yusupov

I. Tiredness to wards the end o f a game It is clear that after several hours of intensive struggle a player becomes tired . But some become more tired than others. It is in the last few min utes that the fate of a game is often decided , and therefore many additional poi nts ca n be gai ned by a player who retains a sufficient reserve of energy towa rds the end of a rou nd .

Insufficiently stable nervous system

Throughout a game it is very important to maintain ful l concentration and u n broken attention to everything that is happening on

Wh ite is a sound pawn to the good , but he now has to resolve a d ifficult problem: what position to go i n for, so that the opponent will have the least i n the way of counter­ chances.

physical preparation ('healthy in body, healthy in mind ! ' ) ; self-tra in in g exercises or even yoga are probably usefu l . Specific chess training is also possible.

An awful move, the fact that White was very short of time is, to my mind, as little to be considered as an excuse, as for instance the statement of the law-breaker that he was drunk at the moment that he committed the crime. The inability of an experienced master to deal with the clock should be considered as grave a fault as a miscalcula­ tion.

2)

time-study of games, with a

subsequent analysis of the reasons for getting into time-trouble.

Poi nts are lost not only in you r own time­ trouble, but also in the opponent's. This happens because a player often disregard s a well-known principle o f h o w t o act i n such s ituation s . If you have the better position, never play on the opponent's time­ trouble. A ct exactly as you normally would, not even remembering about your opponent's lack of time. Why? By

Black's position is, of cou rse, completely hopeless. If 46 . . . '>i'xd5 there follows 47 ::l.d1 + '>i'e6 (47 . . . '.i?e5 48 i..c 6) 48 '>i'c3 . Tylor tries his last ti me-trouble chance . 46 . . .

But in a d ifficult situation the opponent is fu lly composed and mobilised , whereas you , by contrast, l u l led by your advantage i n time and positi o n , a re awa iting the fal l of his flag and a re u nable to play at fu ll i ntensity.

I n the hope of exploiti ng this psycholog ical effect, in d ifficult situations some players deliberately get themselves i nto time-trou­ ble, and there they often change the unfavourable cou rse of the play. Mark Tseitlin - Makarychev Krasnoya rsk 1 98 1

75 lid7 Black resigned . I n the second issue of the American Chess Journal grandmaster Wolff gave an excel­ lent commenta ry on this endgame. By studying his analyses, you , for example, will learn how Wh ite wins if he remains with a pawn on h5 or g5 against a black pawn on h 7 . All this is very i nteresting and usefu l , but nevertheless not essenti al . Whereas the fortress with black pawns on g6 and h5 should defi n itely enter you r store of end­ game knowledge. Why i n particular this position? F irstly, here it is sufficient to learn the assessment of the

position and the basic idea of the defence (not to allow the king to approach the pawns) - you don't have to remember any complicated variations. Second ly, this as­ sessment (draw ! ) is automatically trans­ ferred to positions with a wh ite h- or g-pawn agai nst a pawn on g6 (after a l l , Wh ite ca n play g3-g4 and captu re on g4 with the pawn or a piece). And above a l l , this position is the most u n iversal and i nformative . Very often the pawns of both sides have not advanced fu rther than the 2nd or 3rd ran k , and then it is clear that Black should aim to play . . . h7(h6)-h 5 ! , and Wh ite - g2(g3)-g4 ! .

extra pawns , which , of cou rse , is a lso good enough to w i n . Why then should his decision be criticised? Wel l , because after 78 'it>g5! the game would have concluded - theory, wel l known to Larse n , would have begun. Here it would no longer be possible to go wrong. But after the move chosen by him, play conti n ues i n a n u nfam i l i ar position , which means that t h e probabil ity of a mistake remains.

One of the methods of converting a n advantage is to transpose i nto a n endgame position that is known to be theoretically won .

And here is the decisive mistake , which leads to a d raw. Wh ite should have played either 81 lle6+ Wf7 82 c6 , or 81 .Ud5 .

V. Poor tec h n ique in the conversion of an advantage

The simplest way to win is to sacrifice the c5-pawn. After 78 'i.t>g5 ! .Uxc5 79 'it>g6 followed by 80 l:!.h8+ we reach an elemen­ tary theoretical ending, which is completely hopeless for Black, since his king is on the 'long' side of the pawn . 78 .U.c7?! Bent Larsen decided to keep both of his

naturally to exploit even a seemingly imper­ ceptible advantage, and you will g rad ually beg in to notice their approach to such situations, those principles of converting an advantage which they consciously or sub­ consciously followed , and the tech niq ues wh ich they employed . We will now examine the most general of these principles and methods.

nent has a bad dark-sq uare bishop, and as a conseq uence - weaknesses on the light squares. How can I strengthen my position? The plan of playing the knight from d2 to d5 suggests itself: f2-f3 , i.e3-f2 and tt:'ld2-f1 e3. It would seem that it ca n be beg u n with either 22 f3 , or 22 tt:'lf1 . It also makes sense to play 22 g 3 , depriving the enemy knight of the f4-square . Wh ich of these th ree conti nuations is the most accu rate?

Maximum restriction o f t h e opponent's cou nterchances

Wh ite m ust carefu lly look to see what active resou rces the opponent has, and how he is intending to play. The move 22 . . . tt:'lf4 should not con cern us too much - after 23 g3 tt:'le6 the knight does not create any th reats from e6 and does not control the weak d5-sq uare, for which Wh ite is a i m i n g .

It is very important for every player to possess 'prophylactic thinking' - the

ability to constantly ask yourself: 'What does my opponent want, and what would

he do now if it were his move?' But the role of prophylactic thin king i ncreases par­ ticularly when converting an advantage, when the maxi m u m restriction of the oppo­ nent's possibilities, the e l i m i nation of the slightest cou nterplay or any usefu l opera­ tions to improve his own positi o n, becomes probably the main principle. I will show two examples from my own games .

The attem pt t o create cou nterplay on the kingside with 22 . . . 'ife6 ! followed by 23 .. .f5 looks more serious.

And in genera l , when you have such a solid positional advantage, why calculate such complicated variations? After 22 f3 'YWe6 23 �b3 the captu re on b7 is now seriously threatened , and Black is forced to d ivert either his rook, or his queen, to the defence of the pawn . It is th is move order, therefore , that enables Wh ite to be fu lly prepared for the opponent's cou nterplay. 22 f3 !

The inherent a im wh ich a player should follow when trying to convert a n advantage is not to win as q u ickly as possible. As yet no one has offered p rizes for the smallest number of moves. You should endeavo ur to play with the utmost safety, exploiting a l l the resou rces of you r position and completely restricting the active possibil ities for you r opponent. I t is n o t a misfortune i f you h ave to make an extra dozen moves on the board , if thanks to this you make your task easier and reach you r goal more su rely. In a sharp middlegame you may be tempted by the i mage of tiger, swiftly h u nting down its quarry and tea ring it a part , but when converting an advantage i n the endgame you should rath er imitate a pytho n , slowly suffocating its victi m .

One must possess great presence of mind, to not seize the booty immediately, but do this after several strong preparatory moves. The anticipation of victory often hinders the objection evaluation of a position. It is to this factor that I prescribe the loss of a half point in what was a very important game for me - the most annoying instance in my chess career. This was at the finish of the San Sebastian tournament of 1 91 2, at a moment when I had excellent chances of winning first prize. For me it was sufficient to win against Leonhardt . (Rudolf Spielmann). . .

Of cou rse, Black should have played 46 ... 'it>c3 ! . If 4 7 'it>d 1 , then 4 7 . . . l::.g 1 + 48 'it>e2 b3 is decisive . After 47 .l:!.c7+ 'it'xd4 Black captu res the pawn with gain of tempo, thanks to the attack on g5. Since 48 .l:!.b7? .l::!.x g5 49 .l:txb4+ 'it'c3 is bad for Wh ite , he has to reply 48 .l:i.g7 . Now another tempo can be won by 48 .. .'it>c3 ! 49 ki.c7+ 'it>d3. Look at the position after 50 ki.g7 : as yet Wh ite has not done anyth ing usefu l , whereas Black has eliminated the pawn and placed his king on d 3 .

Wh ite is planning 'it'f3 and e2-e 3 . It is very importa nt that, after the black bishop moves, the c5-pawn remains en prise. It will have to be defended by the rook, but then the white bishop will occupy a n active position on d5, the king will obta i n the excellent square e4, and the rook may be switched along the 4th ran k to the kingside.

A nd yet, contrary to Spiel mann's o p i ni o n, even here he apparently did no t have a win . For example: 50 ... d4 5 1 g 6 .l:tc2+! ( 5 1 . . . b3 52 'it>b 1 !, but not 52 �b7? b2+ 53 'it'b 1 .l:txg6 54 'it'xb2 'it'd2 ) 52 'it'b1 ! (52 'it'd 1 ? .l::!.c6 53 l:tg8 'it>c3 54 g7 Itc7) 52 ... .Uc6 53 'it>b2! 'it>c4 54 l:!.g8 (54 'it>c2) 54 . . . d3 55 llg7 ! (but not 55 g7? �c7 with zugzwang), and Black is not able to strengthen his position .

It would have been better to play the bishop to b2.

Ifthe opponent is deprived of counterplay, before changing the pattern of the play and initiating decisive action you should first strengthen your position to the maximum, by making all moves that are even slightly useful.

47 h6 Black resigned . In cases when one side's advantage is insufficient for a direct win, it makes sense to manoeuvre, without changing the pattern of the position, in order to set

the opponent various problems, even if they are not too complicated . And only when , after failing to withstand the prolonged pressu re , he blu nders or makes some error, can you then turn to decisive action. Such tactics of setting the opponent an endurance test ca n sometimes also make sense in positions with a big advantage. By provoking h im i nto making a mistake , you can make it sign ificantly easier to convert your advantage. Mikhail Botvin n i k remembers: In 1936 in Moscow during the 3rd Interna­ tional Tournament I witnessed the resump­ tion of the Capablanca-Ragozin game. The ex-world champion had an extra pawn and hence a won endgame. To my surprise, however, Capablanca did not undertake any positive action, but stuck to waiting tactics. Finally his opponent made an inaccuracy, and the Cuban won a second pawn and soon the game.

Wh ite u ndoubtedly has a n appreciable positional advantage. H e fi nds a convincing plan to exploit it, i nvolvi ng the creation of th reats on the dark sq uares on the kingside. 1 8 ..txg7 1 8 ..tg5 was also not bad .

' H ow do you explain why you avoided tra nsposing into the endgame? You were in no doubt that it was won . But if you see an elementa ry solution , why then calculate variations and get i nvolved in an excha nge of blows?' The moral of this sad episode is obvious. Always give preference to the simplest way of converting your advantage, in which case the probability of a making a mistake will be minimal. Avoid unneces­ sary complications, and never play 'for brilliancy'.

Converting an Advantage

Any 'trifles', capable of facilitating the conversion of an advantage,

should

without fail be taken into consideration.

If, for example, you do not h ave much time left to the time control , make use of every opportun ity to repeat moves. And after the time control has been reached , defi n itely adjou rn the game, if you h ave a wi n n ing position. If you don't do this, because of tired ness you may make a m istake and spoil your position .

This last piece of advice has ceased to be topical i n view of the change i n the rules of chess competitions - games a re no longer adjourned . The fol lowing example is never­ theless still instructive: it shows that over­ confidence in success, combined with a certain haste and i naccu racy, is capable of having a negative effect on the play of even such a player, deserved ly famed for his fine tech n ique, as Anatoly Karpov.

Alexander Kotov has successfully carried out his plan of tra nsposing i nto a favourable rook ending. In h is commentary he judged the resulting endgame to be won for White. H owever, in Jonathan Speel man's book Endgame Preparation· this evaluation was called i nto q uestion .

Thus if 52 . . . .Uc7 there now follows 53 .Uh8. Do you sense how uncomfortable it is to simu ltaneously defend two weaknesses c6 and h7, and how much easier it would be to defend the weak c6-pawn alone?

The English grandmaster's conclusion ap­ pears not be to com patible with the logi c of the preced ing play - after a l l , White has consistently outplayed his opponent and, it would appear, has the right to count on success. But what can be done - the defensive resou rces in chess a re g reat, especially i n rook endings, wh ich according to Tarrasch a re not usually won . The work done by Kotov was not in vai n - al most out of noth ing he has developed a dangerous i n itiative and posed serious problems for the opponent, which at the board the latter was u nable to solve. 55 . . .

This is what grandmaster Korchnoi had to say: Despite the occasional inaccuracies com­ mitted, I consider my play in the middle stage of this game to be my best achieve­ ment in the match. But I wasn't quite able to complete the strategic picture - at the decisive moment I failed to display the necessary know-how. What was the prob­ lem facing Black? I will allow myself to quote Bondarevsky: 'White's pieces are tied to the weakness at c2, but a single weakness he is able to defend. Korchnoi was faced with the problem of starting play on the kingside, so as to create a new weakness in the enemy position. ' I realised that the move of the h-pawn appeared too routine to be the best. And 1 rejected 29. . . g5 on account of the concrete variation 30 "illd2 f6 31 "ille1 !, when White neutralises his opponent's advantage. But the best move- 29. . . f5 (suggested by Flohr) completely escaped my attention! The point of the move is not only that after the exchange on g4 White's f- and g-pawns will be further weakened; a/so of considerable importance is the fact that, after the ex­ change of queens, Black can create an

G rand master Kotov remembered for a long time the advice given to him by the experienced master Vlad i m i r M akogonov at the i nternational tournament in Venice in 1 950. Don't sharpen the play - what for? Ex­ change the queens, and arrive at a position where each side has a rook and two or three minor pieces left. Which piece should you exchange, and which should you keep ? There are few modern players who can solve this question correctly. They under­ stand tactics, but in this you are superior to them. When trying to convert an advantage you consta ntly h ave to th i n k about the advisabil­ ity of this or that exchange. One of the most general g u ides is given by the fol lowing rule: Having a material advantage, the stronger side should aim to exchange pieces, whereas the weaker side should aim to exchange pawns.

Lack of concrete action at the decisive moment

Let us su ppose that you r opponent has no real cou nterplay and that you , i n accordance with the principle 'do not h u rry! ' , are accumu­ lati ng advantages l ittle-by-little . But against tenacious resistance by the opponent you will probably be unable to win the game by tech nique alone - at some point you will certainly have to switch from positional manoeuvri ng to the precise calculation of variations, and seek a concrete way to the goa l . Many players stumble at this point, with various factors playi ng their part. There is carelessness, arising in a nticipation of a q u ick w i n , about which we have a l ready spoke n . There is the fu lly u nderstandable aim to act 'with every comfort' , not exces­ sively exerting yourself, and not subjecting you rself to the risk of making a mista ke in forcing play.

already extracted the maxim u m from play­ ing accord ing to the principle 'do not h u rry! ' , which mea n s that i t i s time to find a concrete variation, one which exploits the advantage gained and advantageously changes the character of the play. I have noticed that brill iant positional players such as, for example, Salo Flohr or Anatoly Karpov, would successfully convert a n ad­ vantage against opponents i nferior to them in class. They manoeuvred , suppressed all active possibilities by their opponents , and when the latter failed to withstand the pressu re , they made mistakes and them­ selves broke u p their positions. But agai nst opponents of equal class they often did not manage to convert even a big advantage . F o r t h e reason that, w h e n faced with tenacious resistance, you can n ot afford to miss an appropriate moment for concrete and precise actio n , and this is by no mea ns the strongest aspect of such positional players .

Converting an Advantage

made by Flohr was g iven by g rand master Isaak Boleslavsky:

After the move made by White, the picture changes amazingly rapidly.

In this position could White really not find anything better than the strictly positional doubling of rooks? If White really wanted to play positionally, he should have continued 1 6 li:Jd4 ii.. xc5 17 'ika4 ( 1 7 'ir'c1 ! ? Dvoretsky), and to avoid the worst Black must exchange on d4. But the position demanded other measures, and after the energetic stroke 1 6 b4! White would have gained an irresistible attack. Here are some sample variations:

I should also add that after 1 6 b4 ! li:Jxc4 the move 1 7 'ir'xa 7 is the strongest - 1 7 'i'b3 (hoping for 1 7 . . . b5? 1 8 ii.xe6 + ! 'it>xe6 19 li:Jd4+ an d 20 li:Jxb5) is much worse in view of 1 7 . . . li:Jxe3 1 8 fxe3 ii.xf3 .

H i s rooks would then be freed to take action against Black's queenside pawn offensive. At this moment it probably seemed to Stei n that the conver­ sion of his adva ntage by normal methods would not be so easy. If the opponent makes an unexpected move, hindering the implementation of your plans, it is useful to ask yourself: 'What may be the drawback to the opponent's move?' But even after asking

you rself such a question , it is not easy to come to the decision found by Stei n - it is very much not in keeping with the u n h u rried character of the preced ing play, and with Black's intended pla n . 26 . . .

'for ' and 'against'. It looks illogical, since White voluntarily exchanges his 'good' bishop for the opponent 's 'bad ' bishop, instead of exchanging it for the knight (1 8 ..txb6+) and consolidating his advantage. But on a deeper investigation of the position it be­ comes clear that after the possible ex­ change of rooks on the d-file and the transfer of his king to e6, Black covers his vulnerable points and sets up an impregna­ ble position. In this case his 'bad ' bishop would play an important role.

enced players often resort to repeating moves, not only to gain time on the clock, but also in the hope that the opponent will try to change the unfa· vourable course of the play and, by avoiding the repetition, worsen his own position. However, this should be done carefully, avoiding the th ree-fold repetition of the position which occu rred in the present game. It is stra nge that neither Petrosian, nor his opponent, noticed that after 39 . 'it>e8 the position woul d be repeated for the third time and Black had the rig ht to cla i m a draw. Most probably this a l l h appened in a severe time scramble. .

Here I do not agree with h i m - Black's resou rces are not yet exhausted . To say nothing of the attempt, by sacrificing the h7pawn with 38 . . . 'it>f6 , to bring the king to the queenside as q u ickly as possible i n order to hinder c4-c5, he can also play more accu rately in the cou rse of the plan exam­ ined by Zaitsev. 38 . . . h5 39 c4 'iit f6 40 c5 'it>e7 !

It is not possible to queen a pawn : 42 �f5 �b3 43 'iit d 4 �xa4 44 'it>c5 �d 1 45 �d6 �f3 - the bishop has a rrived just in time. And the position arising after 42 'it>e3 �b3 (42 . . . 'it>c8 ) 43 �c6 'it>c8 44 b7+ 'it>b8 45 b6 .ii. d 1 is drawn . The main contin u ation is 35 �xb7 �xa4 36 c4. Black avoids an i mmed iate loss by playing 36 . . . i.b3 37 c5 �g7 .

43 . . . 'it>d6(d8)? 44 «t>b6 h4 45 c7 or 43 h4 44 gxh4 g3? 45 c7! (now it is clear why the king avoided the d4- and c5-sq uares - so that after 45 . . . g2 the pawn should not queen with check), but Black continues 43 . . . h4! 44 gxh4 «t>d6 ! , l u ring the king to b6 where it will be checked , and then 45 . . . g3 (analysis by Zaitsev) . . . .

And th is means that the exchange of rooks most probably would not have saved Black. ,

H ow can the defence be improved? The best saving chances i n such situations are usually prom ised by transposing i nto a rook ending (everyone knows the sayi ng: ' rook endings are never won'). And so, 33 ... �xe4!? 34 .l::txe4 . H owever, after 34 . . . .l:!.g8?

Such a plan for converting an advantage (domi nation and the absence of cou nterplay for the opponent) is fully i n the spirit of Anatoly Ka rpov. From the viewpoint of the practical player, it is very important that here practically nothing needs to be calculated (in contrast to the 33 �e4 variation , where one has to delve both i nto the bishop, and the rook endgame), and this means that the probabil ity of mistakes is reduced . I ncidental ly, the fi nal conclusion about there being only one solution to the i n itial end­ game position (and also about there being only one winning method i n the bishop ending) is fu lly i n accordance with Zaitsev's view: My many years' experience of analysis have convinced me that in tense, balanced positions there cannot be two ways to win. The same thought was also expressed by a nother experienced analyst, i nternational master Gavri i l Veresov: In positions on the border between a draw and a loss, we normally find there is only one solution. 7 . Smyslov - Botv i n n i k (World Champion­ ship Match , 3rd Game, Moscow 1 954 ) Although Black has th ree pawns for a piece, his position is difficult.

But isn't it all the same - after a l l , i n both cases Wh ite remains a sound pawn to the good? But you should not approach the conversion of an adva ntage so frivolously otherwise very often disappointment will await you . You should try to d iscover the difference between moves and choose the one which is i n some way better, more accu rate than the other. If 26 l:!.e2 there follows 26 . . . �c8 , when 27 .l::!.e 6 .l::!. c2 is pointless . Having an obvious advantage, you don't want to compl icate the

play and weaken you r q ueenside pawns by 27 a3 i..f8 . The normal contin uation is 27 g3 Wf7 . We note that the black king prevents o ur rook from becoming active on the e-file, whereas the black rook on the c-file, a long way from the wh ite king, is very active and it restricts the wh ite pieces .

61 c3 the th reat of c4-c5 has become more serious, since now the c5-pawn may be defended by the king . However, it is not hard to forestal l Wh ite's plan: 41 . . . .l:!.h8! 42 h3 .l:!.h5 (42 . . . .l:!.h4 also comes i nto consid­ eration). The rook is wel l placed on the 5th rank - it controls the c5-sq uare (if 43 'it>b4 a5+) and is able to attack any of the enemy pawns. It is evident that Wh ite has not ach ieved much . It remains to verify 39 h4. The reply 39 . . . .l:!.h8! suggests itself (39 . . . f5? 40 exf5+ is bad for Black). Wh ite plays 40 g3, preparing 4 1 l:!.h2 and 42 g4 . How can this plan be countered? Black is saved by the same rook manoeuvre: 40 . . . llh5! 41 llh2 l1a5 ! . Now 42 g4? is u nfavourable because of 42 . . . 'it>e5 43 h5? l:.a3+ and 44 . . . l:Ixa2+, and if 42 �f4 there follows 42 .. .f6 ! , prepar­ ing in the event of g 3-g4 to exchange the opponent's most dangerous pawn by . . . g6g5+ ! . We have establ ished that Wh ite does not achieve anyth ing with the d i rect i m plemen­ tation of any of our i ntended plans. H ow can he nevertheless conti nue playing for a win? Note that everywhere Black was saved by the switch ing of his rook onto the 5th rank. Let's remember about prophylaxis and try to

fi nd a way to prevent the opponent's main d efensive idea. Alekh ine suggests the surprising move 39 h 3 ! ! . Now if 39 . . . l:Ih8 the h-pawn is not hanging and Wh ite replies. 40 c5. After 40 . . . I:th4 the reply 4 1 .l:!.d6+ 'it>e5 42 l:Ixc6 .l:!.xe4+ and 43 . . . .l:!.a4 is unconvincing, but 4 1 l:Id8 ! is very strong. A t t h e s a m e time Black must now seriously reckon with 40 'it>d4 , for example: 39 . . . .l:!.b 1 (b4) 40 '>t>d4 '>t>d6 41 e5+, or 39 .. .f6 40 'it>d4 .ll d 8+ (40 . . .

It is significant that Jose Raul Capablanca ­ a player with bri l l iant i ntuition - was unable to come to the correct decision , suggested by Alekh ine - a player with a totally different way of th i n k i n g. A move such as 39 h3!! can n ot be called i ntu itive, based on 'general considerations' - it could be fou n d only after a deep and very concrete penetration i nto the secrets of the position . Many years ago I was helping Botvinnik by giving some lessons at his schoo l . On one occasion , at the request of Mikhail Moisee­ vich , I prepared an extensive endgame lesson for the young Ga rry Kasparov, which included in particular a n independent analy­ sis of the Capablanca-Aiekhine ending. Garry fou n d a nother way of forestall ing the switch ing of the black rook to the 5th rank ­ the move 39 g3! ! . It appeals to me perhaps even more than Alekh ine's recommenda­ tio n , since it contains an add itional active idea : 40 h4 ! . And there do not appear to be any d rawbacks : for example, if 39 . . . g5 there

Af­ ter a l ittle thought you will see that there is no clear a n swer - i n the process of studying the ending various aspects have come to lig ht, identically important for the practical player. Let's remember what we have seen:

Wh ite has done everything possible to strengthen his position and now is the time for decisive action . The logical consequence of his preced ing strategy would have been the variation 56 'it>e3 ! .ti.c3+ 57 'it>d4 .l:!.xg3 58 .ti.xa5 cj;;f7 (in the event of 58 .. J:tg4 noth ing is given by 59 .ti.a7 .l:!.xh4 60 a5 .ti.h5! , but the reply 59 h5 is unpleasant) 59 .ti.a8 or 59 h5. I n Alekhine's opinion, Black is able to hold the position , but at any event he would have had to defend accu rately. Unfortu nately, Capablanca did not want to sharpen the play and he chose a d ifferent plan, which leads by force to a d raw. 56 g4

57 hxg5

l:txg5!

Of cou rse, not 57 . . . fxg5+? 58 We3 - there is

1 ) Excellent example of a practical rook endgame. Among the n u merous evalua­ tions and methods typical of this type of ending, with which the two players operated, I will single out a comparatively less trivial idea , which is very clearly expressed here. An open line, for wh ich a rook should aim, may be not only a file, as usual, but sometimes also a ra nk. 2) Model example of accu rate defence. It is i nstructive to follow how Alekh ine, without losing his presence of mind in a difficult situation , move by move patiently resolved the problems facing h i m . 3) Various aspects o f t h e problem of converting an advantage. Here we can mentio n : the i m porta nce of looking for a n d forestalling t h e opponent's cou nter-chances (at the very start of the ending); the maxi m um strengthening of Wh ite's position before changing the pattern of the play; the timely tran sformation of an adva ntage (the

Lessons from One Particular Endgame

5 1 st move) ; fi nally, the need at some point (the 56th move) to abandon positional manoeuvring and choose a concrete cou rse, involving precise calcu l ati o n. 4 ) Demonstration o f t h e i mportance of prophylactic th inking. Without it, of cou rse, it is not possible to fi nd the brill iant solution to the position on the 39th move . And subsequently too Alekh ine's defence was based on taking account of all the oppo­ nent's active plans and forcefully opposing them.

5) Grounds for reflection about chess players with an i ntu itive way of th inking. We have seen which decisions a re d ifficult for them or altogether i naccessible. The conclusion suggests itself, that even if you possess splendid i ntuition, you should de­ velop in you rself the abil ity to consta ntly delve into the concrete details of the position and if necessary to accu rately calculate variations. For a chess player it is very importa nt to evaluate objectively the strengths and weak­ nesses of a forthcoming opponent. A sou rce of such evalu ations is provided by an analysis of games played by him. Some of the m will prove especially i nformative. I n the 1 920s Alekh ine was preparing for his duel for the world crown against Capablanca . This is what he recorded for h i mself after the New York tou rnament of 1 924: took home with me from this tournament one valuable moral victory, and that was the lesson I learned from my first game with Capablanca, which had the effect of a revelation on me. Having outplayed me in the opening, having reached a won position in the middlegame and having carried over a large part of his advantage into a rook ending, the Cuban then allowed me to neutralise his superiority in that ending and finally had to make do with a draw. That made me think, for Capablanca had cerI

lZJ

1 63

tainly been trying very hard in this game, so as to draw nearer to Dr. Lasker, who was in the lead, and who had won against me the previous day. I was convinced that if I had been in Capablanca 's position I should certainly have won that game. I had finally detected a slight weakness in my future opponent: increasing uncertainty when con­ fronted with stubborn resistance! Of course I had already noticed Capablanca committing occasional slight inaccuracies, but I should not have thought that he would be unable to rid himself of this failing even when he tried his utmost. This was an exceedingly impor­ tant lesson for the future! Later, in a fa mous a rticle 'The 1 927 New York tou rnament as a prologue to the battle i n Buenos Aires for the world championsh i p ' , Alekh ine once again emphasised t h e role that the game with Capablanca had played for h i m : This game, incidentally, was the starting point for my understanding of Capablanca 's chess individuality. I will also g ive some other assessments by Alekh ine of the style of his historic oppo­ nent, wh ich a re confi rmed by the ending we have examined . They may seem exces­ sively sharp, but to some extent th is is explai ned by the very tense personal rela­ tions which developed between the two champions. But objectively these assess­ ments seem to me to be just (of course, only 'on a g rand scale' - ta king i nto account the very high sta ndard of play in questio n ) . . . . Capablanca is by no means an excep­ tional master of the endgame; his skill in this stage of the game is mainly of a technical character and other masters in certain fields of the endgame surpass or used to surpass him (for example, Rubinstein in rook end­ ings). . . . In Capablanca's games with the years one observes increasingly less delving into

1 64



Lessons from One Particular Endgame

the details of the position, and the reason for this is his unshakeable (I am talking all the time about the period before Buenos Aires) confidence in the infallibility of his intuition. The saddest thing for Capablanca is that this system of his of operating with 'good' moves almost without exception proved sufficient, since to a great extent he was opposed in the positional sense by a more or less

helpless weapon. On account of this 'lack of punishment' in employing not the best moves, he, on the one hand, got out of the habit of that concentration of thought during a game, which alone can give a guarantee against possible elementary oversights, and on the other hand- his self-confidence grew immeasurably and turned almost into self­ worship . . .

Grandmaster Technique

In the summer of 2003 I publ ished an article in the Russian newspaper Shakhmatnaya nedelya and on the Chesscafe site (it was also publ ished somewhere else on the I nternet) with a suggestion that a ru le should be introduced forbidding conversations be­ tween players d u ring play a nd , hence, prematu re d raw agreements . Two years later my suggestion was successfully adopted at the super-tournament in Sofia. Its un iver­ sal adoption would, I am sure, not only lengthen games, but also lower the percent­ age of draws. As we will now see , even i n such a q u iet and seemingly l ifeless situa­ tion, where a draw is indeed the most probable outcome, it is possible to seek resou rces and pose problems for the oppo­ nent.

After the game Valery Yandemirov sug­ gested that he should have played 21 f4. Of cou rse, advancing the f-pawn is not some­ thing that one wants to do - one ca n decide on this move only after employing prophy­ lactic thin king and clearly appreciating the d anger th reatening Wh ite. 21

17 .. .'it'e5 1 8 'it'd4 tt:Jc6 1 9 'ifxeS+ tt:Jxe5 20 �ac1 We have reached the position in the fi rst diagram. The at first sight mysterious move found by grand master Najer is the strongest - it was thanks to it that he won the game. 20 . . .

b6! !

Let us try and reprod uce Black's logic. Fi rst he probably checked 20 . . . tt:Jd 3 and real ised that after 21 .l:r.xc8 .l:r.xc8 22 .l:r.d 1 the position was eq ual. Then his attention was d rawn to the possibil ity of 20 . . . .l::.x c1 21 �xc1 �d8 with the idea of 22 . . . �d2 . Najer is an experienced player and he knows that i n the first insta nce you must check active replies by the opponent - in the given case 22 �c7 . There appears to be noth ing better than 22 . . . .l:r.d2 23 �f2 .l:r.xa2 24 .l:r.xb7, but here Black's advantage is of a purely academic natu re, and he has practically no chances of success. As was confi rmed by the game Li Ruofan-Rowson , 2004 . But after . . . b7-b6 in this variation Black would remai n a pawn up, since from a2 his rook defends the a7-pawn . 21 .l::tfd 1 ? !

Now after 23 �c7 .l:r.d2 the only way of avoiding the loss of a pawn is 24 tt:Jc3 (bad is 24 tt:Jc1 ?? .l:r.d 1 + 25 �f2 �xc 1 ), wh ich allows the u n pleasant pin 24 . . . .U.c2 . The situation after 25 tt:Jb5 .t!.xa2 26 �xa 7 �b2 looks dangerous for Wh ite: the b3-pawn is u nder attack, and he has to reckon with the ma noeuvre . . . tt:Jd3-f4(e 1 ) .

It was pleasant for m e to read the fol lowing comment by Najer about the move 20 . . . b6! ! : A useful move, from which one can identify a pupil of Mark Dvoretsky or at least a careful reader of his books. Evgeny Najer twice pa rticipated in my training sessions and has stud ied my books - obviously, his work has not been in vai n . I th ink that the g randmaster's com ments were evoked by the close similarity of this ending with one of the examples g iven i n my book School of Chess Excellence 3 Strategic Play, which I should now l i ke to show you . (see diagram)

Black's positional advantage is determ i ned by the active placing of his pieces. But it is rather frag ile: the slig htest inaccu racy, and it wil l evaporate. Which is what happened i n the game: 2 8 . . . h 5 ? 29 '.tc1 ! l::tf5 3 0 l::t xf5 tt:Jxf5 31 tt:Je4 g4 32 tt:Jc5+ We5 33 tt:Jxb7 tt:Je3 Draw. A very important principle in the conversion of an advantage is the maxi mum restriction

of the opponent's possib i l ities, and the suppression of a ny cou nterplay, any useful operations a i med at improving his own position . To put this principle successfully i nto effect, use m ust be made of 'prophylac­ tic th inking ' . Let us a s k ourselves what Wh ite wa nts to play. H i s choice is l i m ited . There is no point in attacking the knight: 29 �d2 lle1 + 30 'it>b2 �e5 . Obviously the only sensible operation is to bring the king to the centre : �b1 -c1 d2-d 3 . It is t h i s that s h o u l d be prevented . 28 . . .

Having forestalled the opponent's i ntention, Black can now calmly strengthen h i s posi­ tion . It is not easy for Wh ite to defend. For example, if 30 �f8 there follows 30 . . . .l:!.g 1 3 1 .!:!.f2 �e5 32 ll'le2 � e 1 33 ll'lxd4 'i£txd4, and the dominating position of Black's king guarantees h i m a g reat advantage i n the rook ending .

And now 36 . . . �f4 , 36 . . . ll'lf3 or 36 . . . h 5 . The concl uding position of the variation is very p romising for Black. But is it won? Couldn't Wh ite have played more accurately some­ where earlier? It is clea r that here everything hangs by a thread : the slig htest add itional improvement to the defence, and the game will end i n a d raw.

But a completely d ifferent interpretation of the position is also adm issible. The black king is far more active than its wh ite opponent, which can be especially percepti­ ble in a pawn or knight ending (Mikhail Botvin n i k once remarked : 'A knight end­ game is the same as a pawn endgame' ). Artur Yusupov suggested 28 . . . .l:i.f5 ! ? . Wh ite replies 29 �xf5 (29 �d2 .l:i.f1 + 30 �b2 '.te5 is u nfavourable for h i m ) .

Black's play can be improved . One is struck by the fact that he delayed slig htly - his knight did not i mmediately reach the neces­ sary sq uare f5. Of cou rse, it is desirable to captu re on f5 with the knight. It is this that explains the recommendation by Vad i m Zviagintsev: 28 . . . h 6!? (a mysterious move at first sight, wouldn't you ag ree! ) 29 �c1 .l:i.f5.

Now Black would l i ke t o captu re with the knight, but after 29 . . . ll'lxf5 30 lbe4 ! g4 3 1 lt:Jc5+! (weaker i s 3 1 lbg5+ �e5 3 2 lbxh7 lt:Je3 33 �c 1 lbxg2 3 4 'it> d 2 �f4 35 �e2 tt:lh4) 31 . . . '.te5 32 ll'lxb7 he can hardly hope to wi n . This means that he must play 2 9 . . . �xf5 ! , intending 3 0 . . . 'it>e5 a n d 3 1 . . . ll'lf5. Events can then develop roughly as follows : 30 '.tc1 We5! 3 1 'it>d2 ll'lf5 32 Wd3 (if 32 �e2 or 32 g3, then 32 . . . �d4 is strong ) 32 . . . lbh4 33 g3 tt:lf3 34 h3 ll'lg 1 35 h4 gxh4 36 gxh4. After 30 llxf5 l2Jxf5 3 1 'it>d2 ( 3 1 l2Je4 is now poi ntless - the g5-pawn is defended) 31 . . . ll'lh4 Black must wi n . However, the exchange on f5 i s not essen­ tial - 30 lbd 1 ! (but not 30 lbe4 We5) is far more accu rate for White . For example: 30 . . . .l:i.xf2 3 1 ll'lxf2 ll'lf5 32 ll'ld3, i ntending 33 lbc5+ or 33 �d2 ll'lh4 34 ll'le1 . Little is changed by 30 . . . We5 31 �d2 �xf2+ 32 lbxf2 lbf5 33 �d3, since if 33 . . . lbh4 there is 34 lbg4+ or 34 g3 followed by lbg4+. We see that the position of the pawn at h6 is fa r from idea l .

And yet Zviagintsev's idea is logical - simply it must be put into effect slightly d ifferently. I suggest another mysterious move - i nciden­ tally, the same one that Najer made. 28 . . .

knight ending - is much more concrete and req u i res carefu l checkin g . The q uiet pawn move on the queenside, preparing the exchange of rooks in the most favourable version , can be fou n d only as a result of delving thoroughly i nto the secrets of the position . There a re two aspects to the process of converting an advantage. On the one h a n d , it demands accu ract and methodical play, and on the other hand - an abil ity some­ where to cut short the manoeuvri ng , and fi nd and calculate a concrete way to the goal . It is not easy to sense which is more correct at a particu lar moment. I n the g iven example both approaches seem to me to be equally good , but th is does not often occur. II

Wh ite's position is d ifficult: 30 llxf5 tt'lxf5 or 30 tt'ld 1 llxf2 31 lbxf2 tt'lf5 32 tt'le4 h6, th reatening either to attack the g-pawn (33 . . . tt'lh4 or 33 . . . tt'le3 ), or to penetrate with the king onto the 4th rank. As you see, the similarity with the Yande­ mirov-Najer endgame is not restricted to the fact that in both cases the key to the position was an impercepti ble pawn move. Here there was also the identical nature of the material and the pawn structu re , and also the highly important role played by the activity of the king i n a knight ending - a recu rrent theme of Black's play in both examples. However in the Stean-Hort game fu nda­ mentally different approaches to exploiting the advantage were possible. Which one do you l ike more? The fi rst is purely tech n ical (restriction of the opponent's pla n ; u n h u rried improvement of the position ), but it does not demand deep calculation and therefore it enables time and energy to be saved . The second approach - the transition i nto the

I t can happen that a position looks (and i ndeed is) completely won , and yet a pl ayer does not manage to convert it i nto a win. Very often (if of course, things do not occur in severe ti me-trouble) the cause is a l oss of concentration and insufficient attention to those few resou rces wh ich a re stil l available to the opponent or which suddenly occur. A very i mportant ski l l , enabling this type of mistake to be avoided , is prophylactic th inking, about which I write in l iterally every book of mine. The essence of it is that you need to put you rself in you r opponent's place , consta ntly asking you rself the ques­ tion : what can he u ndertake , and what would you do i n his place if it were him to move? I n some of the examples g iven below the employment of prophylactic th i n king ena­ bled a player to fi nd the opti mal ways of exploiti ng an advantage, which at first sight were fa r from obvious. I n others, by con­ trast, such possibilities were not exploited and the adva ntage evaporated .

the game by Viswanath a n Anand himself: 35 lLlc7 ! Ita7 36 lLlb5. Now 36 . . . lld7 37 'i'c6 leads to the loss of a paw n , while if 36 . . . .l:i:a6, then 37 'it'd 5 .i.e? 38 l:!.c1 - the opponent has practically no usefu l moves . I should mention that in such situations the knight on d5 looks fi nely placed , but that is all - it is not itself attacki ng the weak d6paw n, and is covering it from pressure on the d-file. Therefore the switch ing of the knight to c4 or b5 is a typical pla n . Anand decided not t o change t h e pattern of the position, but conti n ued his unhu rried manoeuvri n g . 35 l:!.d3?

Wh ite's position is strateg ically won , tha n ks to the overwhel ming superiority of his mig hty knight over the 'bad' black bishop. It is also important to note that at the g iven moment the white pieces are active, whereas the opponent's are disunited . If he is g iven time, Black will improve somewhat the placing of his pieces (for exa mple, . . . �d8, . . . 'it>g7, . . . 'ii'b 7, . . . llb8), which , of course, will not change the eval uation of the situation , but will improve his defensive resou rces . This means that now, before this occu rs , a concrete way of exploiting the advantages of Wh ite's position should be sought. Ljubomir Ftacn ik exami ned the plan of creating a passed pawn on the queenside: 35 llb1 !? 'i!Nd8 36 b4 axb4 37 'ifxb4 l:!.a5 - in his opinion Wh ite has only a m i n i mal advantage. I n my view, the adva ntage here is very great - for example, Wh ite ca n play 38 g3!? followed by 39 h4, practically depriving the bishop of any hopes of taking part in the defence of the queenside. However, Black's moves in this variation are not obligatory. A more convincing way was poi nted out after

35 . . . 'i!Nc8? was completely bad : 36 t2:lb6 'iVxc4 37 tt::lxc4 .i.e? 38 lld5 ( Ftacnik).

Of cou rse, this evalu­ ation is too pessimistic and was undoubt­ edly infl uenced by the result of the game. 36 llc3

But I am not convinced that Wh ite is guara nteed a win after 38 . . . Wg7 39 b4 axb4 40 llxb4 �a7 4 1 l::Ix b8 'i¥xb8. We saw a similar situation i n Ftacnik's variation (35 llb1 ), but there the bishop was u nable to return to the queenside.

3 8 g3? I n accordance with the principle 'do not h urry' White gradually strengthens his position . Alas, the useful move made by h i m is in fact a serious mistake, which puts the win i n jeopardy. What is the poi nt? How can this be explained a n d , what is far more i m portant, recogn ised d u ring a tou rnament game? The point is that, apart from the long-term advantages of his position , here Wh ite also has one tem pora ry plus: the possibility of occu pyi ng the 7th ran k with his rook (the immed iate 38 llc7 does not work because of 38 . . 'ii'x b3, but he can fi rst sacrifice a pawn : 38 b4 ). I n combination with the su bseq uent attack of the queen on the f7-point, the idea looks tempting and therefore it should be thoroughly checked . After all, if Wh ite delays slig htly, Black will cover the c7 -point with 38 . . . ..lli.. d 8, and such an opportu n ity will not occu r agai n . All the other advantages will rema i n , of cou rse, but who knows whether they will suffice for a win? .

S o , 38 b4! axb4 39 llc7 'it'a8 . I n lnformator Anand suggests only 40 'ii'f3? ! llf8 (after 4 1 'i'b3 �dB Wh ite has noth ing special). The immed iate 40 �b3 ! is more logica l , blocking the opponent's passed pawn and a i m i ng at the f7-point. The only sensible reply is

The correct scheme of attack was suggested by Igor Za itsev: 41 g3! with the idea of 42 h4. The black bishop turns out to be at the cross­ roads: a move along either d iagonal will i nvolve serious concessions. I n the event of 4 1 . . . �d2? a swift mati ng attack proves decisive : 42 'ii'f3 .Uf8 43 'i!Vf6+ '.t>h6 44 ltJe 7 ! . If 4 1 . . . ..lli.. d 8 there follows 42 .Ud7 , and there is no satisfactory defence against a move by the knight: after a l l , the rook's path to f8 is blocked by its own bishop. If 4 1 . . . llf8 ! ? is played immediately, then after 42 I:.b7 Wh ite captu res the b4-pawn and ach ieves a decisive su periority on the queenside - the enemy rook is not able to help, since it is tied to the f7-point. 42 . . . ..lli.. d 2 43 'i!Vf3 ..lli.. g 5 (43 . . .

Now the shelter of Black's king is sign ifi­ cantly weakened (true, in retu rn he can hope to exploit the open ing of the f-file for a cou nterattack - but things never come to th is). Anand rejected 43 . . . hxg6 because of 44 'it'g 1 ! ? with an attack on the h-file. Perhaps he should have taken a risk. After 44 .. .f5 45 'i'h2 �f6 the offensive is not so easy to organ ise. I n the event of 46 'i¥h6 i.. g 7 47 'ii'g 5 (47 'ii' h 7+ 'iii f7 48 :a 1 l::!. a 7 with the th reat of . . J la8-h8 ) 47 . . . l:l.f7 no mate is apparent, and it is not possible to switch the queen to the opposite wing, because of counter-th reats to the king : 48 'i¥d8+ i..f8 49 'i!i'xa5? fxe4 50 fxe4? 'ii'g 4 , and it is Black who wins. Artu r Yusupov found the correct idea: 46 'iVh3! followed by the i nclusion of the g-pawn in the storming of the enemy king's de­ fences. For example: 46 . . . .l:.f7 47 g4! fxe4 (47 . . .f4 48 'ilfh6 is u n promising for Black) 48 fxe4 l:tb7 49 'iit g 3 l:.f7 50 'ii' h 6 �g7 51 'ii' h 7+ 'itf8 52 g5 (Black is i n zugzwang ! ) 52 . . . .Ua7 (52 . . . l:.d7 53 l:la 1 ) 53 l2Jf6 Vf7 54 .l:[f1 i.. xf6 55 'ir'h6+ 'ifg7 56 l:txf6+ l:.f7 57 1:.xg6 or 57 l:.xd6 with a n easily won rook ending. However, Polgar could also have played as i n the game: 44 c5 dxc5 45 Wxc5 , althoug h here this move is sign ificantly less strong. Black creates sufficient counterplay, by conti n u ing either 45 . . . f5 ! ? 46 'i!fxa5 iic8 ! , or as recommended by the I ndian player Sundararajan Kidambi: 45 . . . .l:tb8 ! ? 46 'i!fxa5 l:.c8 47 l:.f1 (47 l2Jxb4 'ilfd6 or 47 . . . i.. e 7) 47 . . . .l:tc2+ 48 .l:tf2 l:.xf2+ 49 'iiixf2 'iVh3. (This mea ns that i n the 43 c5? ! dxc5 44 'ii'x c5 variation Black should play not 44 . . . 'ilfa6? ! , but 44 . . Jlb8 ! ) . I t usually makes sense t o pose t h e opponent such a choice .

But now I will explain why Black's 33rd move was awarded not an exclamation mark, but a '!?' sig n , expressing some doubt. The point is that the opponent could have repl ied 34 l:!.e 7 ! . The only way to retai n the two extra pawns is by 34 . . . f5 35 .txd3 l:Ixd3 36 .l:!xd3 'i!Vb 1 + 37 'it>h2 'i!Vxd3 , but then there follows 38 'it'c5 ! , intending 39 'i!Ve5 .

A typical way of converting an adva ntage is to exchange the last pieces and transpose i nto a pawn endgame. The point is that pawn endings ca n usually be calculated right to the end. If the resu lts of the calculation are favou rable for you , it will no longer be necessary to play the position move by move (with a non-guaranteed outcome and the danger of making a mistake at any moment) - by forcing events, essentially we simply demonstrate a n arrived-at solution. In the given i n sta nce the exchange can be carried out by switching the bishop to g2. Let us check the variation s . 33 .tf1 !

'it>e8

34 .tg2

.td5

I doubt whether, with the opponent's pieces so active, Black will be able to exploit h i s material advantage. B u t t h e n t h e question arises : should he have carried out the combinatio n , and wouldn't it have been better to prefer the simple move 33 . . . .l:tfd 8 , retaining a great advantage?

34 . . . .txg2 35 'it>xg2 is hopeless - Wh ite's outside passed pawn will a utomatically decide the outcome. The attempt by the opponent to avoid the excha nge also does not pose any problems: 34 . . . .td3 35 i..c6+ ! 'it> d 8 3 6 b6 'it>c8 37 f3 followed b y 'it>f2-e3 .

The conclusion : when forcing events i n a favou rable situation , it is important to check thoroughly the variations and eval uate their consequences - otherwise you can easily squander you r adva ntage !

A d ifficult move - usually it is not recom­ mended to improve the opponent's pawn structure . Here this is justified by the possibil ity of a pawn breakth rough on the kingside.

playing 29 . . . .l::!.e 4! 30 .l:!.xa5 .l:!.c4 . Only 29 f3 ! l:tc2 30 .l:!.c5 is correct, when the loss of a second pawn is inevitable. 27 l:!.d1 27 a5?! is prematu re on acco unt of 27 . . . .:tc6. F i rst the rook m ust be tied to the defence of the bishop.

There is another idea which deserves to be stud ied : to remove the a-pawn from the attack by the bishop, i n order to retai n both threats : ii.xa6 and .l:f.d 1 (as is wel l known , often 'the threat is stronger than its i m medi­ ate executio n ' ) .

But i f t h e a-pawn is moved two squares forward , thi ngs will be bad for Black i n the rook ending, and also there will be the additional possibil ity of fixing the weakness at a6 by a4-a5. 26 a4!

I n the event of 29 g3? (or 29 Wf1 ? ) Black is able to avoid the loss of a second pawn by

28 l::i. x d5 l::i. x d5 29 ii.c4 is threatened - for this reason there is no time for 27 . . . a5. If 27 . . . 1i.b7 there follows 28 .l:!.xd6 cxd6 29 a5! , and the bishop ending is undoubted ly won : Black is not only a pawn dow n , but he has also been saddled with a wea k pawn on a6, fixed on a square of the colo ur of his bishop.

And i n the rook ending after 28 .l:i.xd5 .l:!.xe2 29 Wf1 .l:f.a2 it is not possible to win a second pawn .

Wel l , fi rstly, it is very i nteresti ng to deal with a genui nely conscientious analysis . You know, when you read a phrase l i ke 'such-and-such a move ca me i nto consideration ' , it says noth i n g . Yes, i t no doubt came i nto consideration . It is a qu ite d ifferent matter, if the com mentator tries to investigate what was correct, and what was wrong. One can agree with Emel i n 's assertions or d ispute them , but here at least there is someth ing to th i n k about. Secondly, it fits i n well with the basic theme of our session . From the open i n g , play went directly into a favourable ending for Wh ite . The problem of the tech n ical conversion of his adva ntage faced Emelin throughout the enti re game.

Black also has another idea 23 . . . l:tf8 ! ? (instead of 2 3 . . . .1i.c8) . It is desir­ able to defend the a7-pawn with the rooks from the side.

Note that i n m a n y variations t h e defensive plan i nvolves playing the king to the centre , to d6, or exploiting the open c-file. All these resou rces appeared as a result of the exchange of the 'wrong' rook on the 24th move!

E. After 35 'it>d3 Wh ite has an obvious advantage.

Yu . On f6 the knight has no futu re - it must be moved from there. The only question is whether to do this immed iately, or fi rst prevent g4-g5.

D. Black's position is i ndeed u npleasant, but he still has some cou nterplay. 35 . . . c6 suggests itself, with the i ntention of attack­ ing the wh ite pawns on the b-file.

E. Black would have d o n e better t o choose 27 . . . h6. O n h 7 the pawn is weaker than on h6. Then I was intending to play 28 .ti.h 1 'it>g7 29 tt:'lb3.

Yu . It transpires that the move b2-b3 had not only virtues! D . The exchange of bishops on f5 is a double-edged decision , since Black's 'bad' bishop is exchanged.

When you sta nd better in an endgame, you must all the time keep an eye out for sudden activity by you r oppo­ nent. I th in k it is typical of Vasya to underestimate his opponent's possibilities. This is dangerous, and is l iable to cost many poi nts, especially when trying to convert an advantage.

Of cou rse, after 33 . . . axb4 34 .llx h6 the position favou rs Wh ite, but 34 . . . .l:!.c1 retains some cou nterplay. True, after 3 1 . . . a5?! there is a far more u npleasant reply: 32 l:Ic1 ! . Therefore Black should try 31 . . . b6!? 32 tt:Jxa6 h 5 33 gxh5 tt::lx h5 or 33 g5 tt::l h 7 34 f4 tt::lf8 with some cou nterplay. I n difficult situations it is someti mes worth defending in this way - sharply change the pattern of the play, and go i n for material or positional concessions for the sake of activating you r forces. Wh ite ca n double the opponent's pawns : 30 i.. x b5 axb5 31 tt::lc 5. I had i n mind 3 1 . . . b 6 32 tt::le 6+ 'it>f7 33 tt::l d 4 .l:tc4 34 'it>d3 h5. Yu . Unfo rtu nately, after 35 b3!

D . It is good that such a n a nalysis has been made! It would be simplest to stop here and say 'Wh ite has the adva ntage ' . Yes, the advantage , but is it sufficient for a win? I n over-the-board situations there i s not usu­ ally any particular point i n seeking an answer to this q uestion - it is sufficient to u nderstand whether o ur position has im­ proved or deteriorated, and whether we have extracted the maxi m u m possible. But when there a rises a position which can be eval uated exactly, you should endeavour in analysis to establish the truth . 28 .l:ta5? ! E. I should first have played 28 g5! , fixing the h7-paw n .

E. Another possibil ity is 28 . . . tLlc7 . Then 29 g5 rJ;,;e7 , and here Wh ite does best to retreat his rook to a1 with the th reat of 31 .Uh 1 . If he plays the i naccu rate 30 .l:lc5 ? ! , then after 30 . . . rJ;;d 6 31 .Uc1 tLle6 ( 3 1 . . .

Perh a ps instead of 59 We5 Wh ite should change pla n : 59 i.f7 and 60 g6. After all, now the black bishop does not manage to go via f3 to h 5 .

In one of his a rticles Bent Larsen asserted that long variations always have some mistake in the m ; when he sees them, it awakens i n him the i n stinct of a killer, a striving to immed iately bury the entire analysis. Yu . Let's return to the position after 58 b3. The white b-pawn is vulnerable - this is suspicious. Since everything else loses, let's try allowing the wh ite king to go to e5. 58 . . .

It appears that here mutual zugzwang positions beg i n to a rise. Wh ite ca n try 59 i.e6 (seeing as after 59 . . . 'it>b5 60 i.xd5 we have fou n d a w i n ) 59 . . . 'it>d6 60 i.f7 . D. Black replies 60 . . . i.f3 . We have reached a position wh ich we a l ready had after the 56th move, only the wh ite pawn has moved to b3. Yu . So, as yet we have n 't fou n d a win. It has to be investigated whether Wh ite's plan can be improved . Vasya , please do this at home, to complete you r analysis. D . Later Erne/in found a simple improve­ ment.

D . I was watch ing this game when it was played . From the side, of cou rse, you don't delve i nto details, but some general impres­ sions nevertheless rem a i n . It seemed to me that the wh ite rook had strayed off cou rse and was cramped among the black pieces and pawns, as a result of which the opponent later acq u i red excellent saving chances. If Black did not h ave a knight, the rook would be excellently placed on b6, tying the enemy rook to the defence of the b7-pawn . But the knight on d6 seriously restricts the activity of the wh ite rook. Now we will contin u e the analysis of the game. 29 b5? E . Here I was over-hasty. Aga i n I should have fixed the enemy pawn s by 29 g 5 ! . Yu . You began action on t h e queenside, without completing you r work on the kingside. E . I miscalculated : I considered 29 . . . axb5 30 .l:i.xb5 tt:'Jd6 3 1 l:tb6 �e7 and though that I would win a pawn by 32 tt:'Jb5. I overlooked the reply 32 . . . l:rc6 . Yu .

Yu . Here it is not a matter of specific moves. It is clear that Wh ite has strayed from the correct cou rse . His rook on b6 is i nactive , merely attacking the b7-pawn , which is secu rely defended by the m i nor pieces. If the rook had been on a 1 , none of this counterplay would have arise n ; on the contrary, it is the wh ite rook which would have created th reats from h1 or e 1 . An advantage is usually accu mulated l ittle­ by-little, but it can also be lost l ittle-by-l ittle . Thus here Wh ite h a s lost t h e g reater p a rt of his advantage as a result of such a 'trifle' as the poor position of his rook. I n this ending the rooks are the strongest pieces, and their activity is of enormous sign ifica nce . Both players u nderestimated the i mportance of this factor. E. It is not essential to play 35 �d4 - the rook can be brought out via b4 . D. But then you are forced to lose ti me. Besides, 'it>d4 forces the black bishop to take up a passive position on c6 . Whereas i n the event o f 3 5 l:!.b4 you constantly have to reckon with an exchange of minor pieces on f5.

D. You see, with your roo k on the a-file the bishop wou l d n 't h ave bothered you at all. Whereas here the bishop restricts the rook. But even so, you shouldn't have excha nged it. 34 . . .

E. Good d rawing chances were offered by 34 . . . bxc6 ! . After 35 'it>d4 the most accu rate reply is 35 . . Jlc7 ! . 35 . . . 'it>d7 is weaker: 36 'it>c5 ( 3 6 'it>e5 l:!.e8+ 37 'it>f6?? lle7 and the king is in a mating net) 36 . . . l:!.c7 37 l:!.b8 . D. Even so, the king move looks natural - it frees the rook from the defence of the c6pawn . I suggest checking 35 . . . 'it>d7 36 'it>c5 tt::lf7 ! . The enemy king on c5 is too strong Black must try to evict it. If 37 .l:tb7+ , then 37 .. Jk7, while if 37 f4 1 reply 37 . . . tt::l d 8 38 f5 'it>c7 (or 38 . . . .l:ta8). Wh ite retai n s the better chances, but the play is not just in one d i rection , and the situation becomes rather tense. Yu . Perhaps Wh ite should nevertheless exchange rooks: 37 .l::I b 7+ llc7 38 l:!.xc7+ �xc7 39 f4 . D. I must play my knight to b7. But not necessarily via d8 - I will try 39 . . . tt::ld 6, restra i n i n g f4-f5 . Yu . Then 40 g4 tt::l b 7 + 4 1 'it>d4 'it>d6 42 f5 . D. The g-pawn has to be given u p , but in return Black ca n become active in the centre : 42 . . . c5+ 43 'it>e3 c4 44 fxg6 hxg6 45 ..txg6 'it>e5 followed by . . . d5-d4+. If he can manage to exchange on the queenside, the d raw will be not far off. E. I n the minor piece endgame I also considered a nother defensive idea: at the point when f4-f5 is played , to answer . . tt::lf7 , captu re on g5, and block the remaining wh ite pawn with the knight. .

34 tt::lx c6+? E. I should probably have withd rawn my rook. I was simply tired of playing against this bishop and I decided to exchange it.

Yu . A good pla n . Apparently Black does i ndeed have good d rawing chances. E. I also do not see how Wh ite can win after

The first problem which both players en­ cou ntered was how to a rrange their pawns . First there w a s a clash on t h e queenside. With b3-b4 Wh ite threatened to cramp his opponent, and the latter did not find anything better than to reply . . . a7-a6. In principle, with a lig ht-squa re bishop it would have been better to keep the pawns on dark squares. Then a similar problem arose with the kingside pawns. Black should certa inly have prevented the activation of the wh ite pawns with g 3-g4 , by playing . . . h 7-h5 . But he

Analysis of a Game

chose what was probably the worst set-up and allowed h imself to be cramped . There was an interesting point i nvolving the exchange of rooks. It is importa nt to remem­ ber than in the endgame you r rook should aim to occupy a fi le which is remote from the enemy king , so that it does not prevent a n invasion on t h i s fi le. The game could have turned i nto a g raphic demonstration of the principle of two weak­ nesses, but Vasya did not fix in time the second weakness on the kingside by g4-g5 (the fi rst weakness is the isolated pawn in the centre ) . If he had done this before playing b4-b5 , he would certainly have stretched the opponent's defences more convincingly. At the same time he violated the principle 'do not h u rry ' , which demands that the position should be improved as much as possible before turn i ng to active measu res changing the character of the play. The main theme of the fu rther cou rse of the game was the activity of the rooks, which is extremely important not only i n rook end­ ings. Wh ite took his rook to b6, where it was hardly doing a nyth ing at a l l . In tu rn , Black delayed the activation of his rook. As usually occu rs i n the playing of endings, on several occasions there was the need to assess the advisabil ity of various piece exchanges. And by no means always did the two players act correctly. A strong impression was made by the analysis of the bishop endgame. And it doesn't matter that in it we discovered a vul nerable place. I n the solving of compli­ cated problems, such errors are practically i nevitable. In general the commenta ry was very in-

formative , but I gai ned the impression that towards the end Vasya became a l ittle tired , and stopped d rawing attention to resou rces for the opponent. I n cidentally, i n positions of this type, when you have a slight adva ntage and the opponent has no cou nterplay, it is very important to watch for h i s possible activity, and not al low h i m to i n itiative double-edged clashes. Excellent examples of this can be found in the games of Anatoly Karpov. There is no way that he would have allowed the black rook to go to c1 . D. I n the g iven instance the underestima­ tion of the opponent's possibil ities was seen mainly i n the variations and less i n the game itself, possibly because the opponent played passively. But in other games from the same tou rnament this deficiency g reatly h i ndered Emel i n . Remember, for example, his game agai nst Zifro n i , the fi rst pa rt of which we have see n . A clearly better ending with an extra pawn was even lost! I n the last rou n d , after excellently outplaying his opponent, Vasya blu ndered , missed a win , and as a result he fi n ished half a point behind J udit Polgar. When I was watch ing the game, I gai ned the impression that Wh ite was trying to convert his adva ntage in a non-method ical way. But the impression could have been fa ulty, and to check it I found it very i nteresting to look at his analysis . Now we have seen that White did indeed make a number of positional errors. I n my view, the conversion of an adva ntage is one of the weakest aspects of Vasya's play, as usually happens with players who are incli ned to underestimate their opponent's resou rces . He should do some serious work on this problem.

The examples g iven below, a n no­ tated by our pupils, became a topic for discussion at joint or individual lessons. The young players' analyses were critically evalu­ ated , and the results of these d iscussions form the basis of the present chapter. I hope that the readers will fi nd much that is usefu l and i nteresting in these endings played by young players - they conta i n both success­ ful decisions, and typical m istakes.

The resulting situation is rather i nteresting . It is difficult to g ive it a clear eval uation immediately. Wh ite hopes soon to obta i n two con nected passed pawns. On t h e other hand , we know about the strong drawing tendencies of such endings: a m i n i mal

material advantage may prove i nsufficient for a wi n . Let's try to point out the special features of the g iven position . Two details help Black to defend: 1 ) The passed a-pawn may d ivert the white bishop or restrict its mobil ity - thereby it will i nd i rectly defend the kingside pawns which are situated on l ight squares. 2 ) The corner sq uare h8 is i naccessible to the opponent's bishop. This factor enables Black to d raw with a lone king against king, bishop and h-pawn - a n i m porta nt resou rce in many endings. I n principle, it is a l ready possible to guess the fu rther development of events . Wh ite will adva nce his f- and e-pawns, if necessary supporti ng them with the g-pawn . Black

And the players agreed a d raw. Note should be made of the largely compe­ tent actions by Zviagi ntsev, who q u ickly coord inated his forces and frustrated the opponent's plan by a timely attack on his pawns. But did Wh ite make use of all his resou rces? Let us return to the position after Black's 49th move .

Fi rstly, Wh ite has to h u rry with this attack, since with the pawn on a4 it is pointless to threaten the h 7-pawn i n view of the reply . . . a4-a3 . Here , however, there is no contra­ diction with the afore-mentioned principle. ' Do not h u rry' by no means sign ifies marking ti me. The essence of the principle is that before making decisive changes to the position you should try to squeeze the maxi m um out of the existi ng structure. The second comment relates to endings with opposite-colour bishops. We know that for the defending side it is normally advantageous to arrange his pawns on squares of the colour of his own bishop.

The g iven example is i nteresting for the fact that it shows: one should not blindly and literally follow rules without taking into account the features of the specific position. Wh ite's plan is to advance his

kingside pawns . The fact that the g6-pawn will be undefended will force Black to advance or exchange it, conced ing the key f5-sq uare to the opponent. This was probably that small deta i l wh ich was lacking in Wh ite's wi n n i ng mechanism. 50 ... h6 51 f4

I n the chapter 'Converti ng an advantage' Mark Dvoretsky d rew attention to the impor­ tant pri nciple ' do not hurry!' One of the aspects of this principle is attention to 'trifles' . Don't neglect even the slightest opportunity to strengthen your position or worsen the opponent's.

I n the diagram position Wh ite could have weakened the opponent's pawn chain by 50 �g8 ! . Here I should l i ke to make two comments:

The hasty 5 1 �f7 g5 52 �e4? was weaker in view of 52 . . . �c3 ! . But now, if Black defends as in the game, he will no longer be able to set up a fortress: 51 . . . a4 52 e4! .ig1 53 e5 a3 54 h 3 �c5 55 g4 �c6 56 f5 gxf5 57 gxf5 �d7 58 'Oti>e4 �c5 59 f6 �e8 60 'it>f5 'Oti>f8 6 1 �c4 �b4 62 e6 h5 63 ..ti>g5 etc. H i s position is also not eased by 5 1 . . . .id6 52 g3 (with the th reat of e3--e4--e5) 52 . . . g5, after which , if there is noth ing better, there can follow 53 f5 �c5 54 �e4 �c6 55 �b3 ! �c5 56 �e5! �xe3 57 �e6 a n d 58 f6 . Even so, the defensive resou rces a re not yet exhausted (again remember about the 'drawing tendencies' of endings with oppo­ site-colour bishops). Let us try 51 . . . 'iti>b5 ! .

black king j ust in time joins i n the battle against the passed pawns. For example: 54 f6 a4 55 'lt>e4 'it>d7 55 g4 .

The simplest way to d raw is by 55 . . . i.b6! 56 i.c4 'it>e8 ! , when Wh ite gets nowhere with either 57 'it>d3 i.dB or 57 Wf5 i.xe3 58 ..t>g6 i.d4 The routine 55 . . . a3?! is less accu rate in view of 56 i.a2!

'it'd? 58 e4 'it>d6 59 'lt>c4, and there is no defence against 60 e5+ . I ncidentally, after 56 i.b3? ( i nstead of 56 i.a2 ! ) a defence would have been fou n d : 5 9 . . . a2! 60 i.xa2 i. a 3 . Nevertheless, as Alexander Motylev indi­ cated , Black also does not lose here, if i n reply to 56 i.a2 ! he chooses a cou nter­ attacking plan: 56 . . . '1t>d6! 57 'it>f5 i.xe3 58 'it>g6 ..t>e5 ! 59 f7 �c5 60 Wh5 i.e? 6 1 �b3 ..t>e5 with a d rawn position . 5 2 e4! i.g1 ! 5 3 e 5 ! (53 h 3 ? i.h2) 5 3 . . . i.xh2 54 '1t>e4 a4! Otherwise 55 �f7 g5 56 f5 wins easily.

The primitive 55 g4? 'lt>c6 56 f5 gxf5+ 57 gxf5 Wd7 58 f6 'lt>eB 59 i.c4 a3 60 'lt>f5 (60 'it>d5 'lt>f7 ! ) 60 . . .'1t>f8 61 e6 i.d6 62 'lt>g6 i.b4 63 'it>xh6 �c5 leads to a d raw. The wh ite bishop can not take control of the impo rtant e8-square , and therefore the black king easily prevents any attempt by the oppo­ nent's king to help its pawns. P u rely study-like su btleties a rise i n the variation 55 e6? ! 'it>c6 56 'it>e5 i.g3 ! (other­ wise 57 e7 'it'd? 58 'it>f6) 57 �f7 �h4 58 �xg6 (58 g3 a 3 ! ) 58 . . .'it'c7! (but not 58 . . . a3? 59 �b1 'lt>c7 60 f5) . N ow after 59 i.c2 the obvious 59 . . . a3 60 �b3 '1t>d8 loses to 61 'it>f5! �g3 ( 6 1 . . . 'it>e7 62 'lt>g6) 62 'it>f6. Black should not cl ing on to the pawn - the blockade is more important: 59 . . . ..t>d8! 60 i.xa4 'it>e7 61 ..t>f5 i.e 1 62 i.b3 i.d2 with a d raw. The most da ngerous is 59 g 3 ! a3! 60 gxh4! (60 i.b1 i.xg3) 60 . . . a2 61 e7 a 1 �+ 62 ..t>f5 �b 1 + 63 ..t>f6 , but I somehow don't see how Wh ite wins after the approximate 63 . . . �b4 ! 64 f5 "iWxh4+ 65 ..t>f7 "iWc4+ 66 'lt>g7 'it'd4+ 67 f6 �d7 68 Wf8 (68 �f5 �eB 69 i.e6 '1t>d6 ; 68 �f7 �g4+ ) 68 . . .

been demonstrated - this dema nded an a nalysis 35 ( ! ) moves i n length (done together with Dvoretsky). Such lengthy variations a re rarely without mistakes, and therefore it is q uite possible that the readers will fi nd either a defence for Black, or a shorter way for White to win . [As was already mentioned earlier, it is advantageous for Black to exchange all the kingside pawns: the position with white pawns on e6 and f6 against a black pawn on a3 is drawn. This factor suggests the correct plan of defence. This position would appear to a rise by force. It is not possible to mate the black king , and therefore Wh ite's aim is to exchange the queens, then capture the g6-pawn and win the bishop for the f-pawn . This plan is q u ite realisable, although not without some d iffi­ culty.

Let us examine the consequences o f the rook exchange. After 35 ..
