Prologue This book is an arsenal providi ng essential ammunition in hand for all White players who wish to open with I d4. The outst feature is its intention of reducing the areas of conflict to tho which t he·reader is familiar and, t herefore, competent and confi handle. It would be wrong to claim that the variations exam ined confer advantage on White, but the systems presented here all confor basic solid but aggressive style. It is my belief that a reader who is in tune with the patterns displayed in this book will feel happy v lines I have recommended and will, therefore, score more poin An Opening Repertoire for White (OR W)

Note on Algebraic Notation The notation used in this book is algebraic, the only type approved by FIDE, the World Chess Federation and the governing body of international chess. If you can understand a London A-Z guide or a Manhattan street map you will have absolutely no problems in comprehending algebraic notation, which is more economical and less prone to ambiguity than the alternative and outmoded descriptive variety. A brief examination of the following diagram will im mediately clear up any possible confusion concerning the application of algebraic notation.

Introduction The aim of this book is to provide a complete repertoire for the White player, based on the move I d4. I n analysing the material I have chosen to develop from I d4, I have maintained several crucial principles: one main line is demonstrated for White against all of the major Black defences which the White player is likely to meet in competition; the mai n lines selected are sound but a ggressive and do not rely on memorisation of long tactical variations a nd su b-variations. In several cases, they embody newly elaborated, relatively unexplored ideas which allow plenty of scope for individ ual creative contribution on the part of the reader. Furthermore, I have based each suggested line on annotated illustrative games, so that the strategies outlined and attacking methods proposed can be fully a bsorbed, right up until the endgame phase.

Advantages of a Repertoire There is no need to feel concern at limiting oneself to an opening repertoire. All chess players have restricted time and resources at their disposal, and this is particularly true of social, club, league or weekend competitors. In view of such constraints it makes excellent sense to work out a tangible, fixed group of opening variations in which to carry out a specialised study. O nce the reader feels thoroughly at home with this, it will provide a firm platform for branching out and acquiring new knowledge and expertise in other, broader areas of chess science. It should not be forgotten that even such great players as Fischer and Karpov have had their own selective repertoire, centred largely on I e4, while Vi ktor Korchnoi and Gary Kasparov strongly favour openings arising from I d4. A cu rious fact, in this context, is that of the twenty games played in the World Cha mpionship semi-final at London 1 983, in the matches between S myslov and Ribli and between Korchnoi and Kasparov, no less than nineteen commenced I d4! I d4 is a sound, solid move, aiming for central control and a restrained but ultimately convincing attacking build-up. It does not lend iiself to premature adventures and in general, by opening with it, you can avoid colliding with too many devastating surp rises from your opponents.

inlroduction

Link with 'BCO'

OR W (An Opening Repertoire for White) is designed to give the reader confidence and ideas for t he practical st ruggle. As I have already stated, this is essentially a book of strategies, not an exhaustive reference work . I have, therefore, taken the step of linking each variation analysed with the related section in Botsford Chess Openings (BCO). This o ne-volu me openings encyclopaedia, written by Gary Kasparov and myself, provides a vast amount of detailed background information. It is a useful companion to OR W, and one that will form a handy compact compendium, both for expanding the repertoire beyond the confi nes of the lines l have exami ned here and for last-minute rev ision before and du ring tournaments or impo rtant games. Good luck with improving your chess and your scores!

concessions in the line 3 lt:lf3 .ig4 4 cd .ixf3 5 gf, such as surrender of the centre, exposure of the black queen and Joss of the bishop pair. In return for all t his, Black's counterchances against White's slightly fragile king position seem somewhat nebulous: Furthermore, in the line 3 lt:lc3 Black has o survive an immediate onsl:�g which has claimed a number of victims, including the author! M y standard method in this book will be to give just one line against each Black alternative, but against the Chigorin I mention two White possibilities (here and by transposition in Chapter 1 8), since both are good but will appeal to different styles of player. In contemporary tournament practice S myslov and Miles have occasionally upheld the honour of the Chigorin, but no modern grandmaster is prepared to make a living out of it - it remains, essentially, a surprise weapon. It is analysed in BCO on pages 54 and 55.





This remarkable concept was introduced in t he late 1 9th century by the great Russian player Mikhail Chigorin, who used it to defeat such supermen as Lasker and Pillsbury. This was at a time when Dr Tarrasch was claiming that his defence, 2 . e6 3 lt:lc3 c5, was the only correct antidote to the Queen's Gambit, and even the Slav, 2 c6, was considered highly unusual. In spite of Chigorin's personal success, his defence did not capture the public's i magination, poss ibly because Black is committed to rather too many positional . .

lP . which has never bee � reYu�ml't unlike the Benko Gambit, which has fi rmly established itself as a respectable black defence in inter­ national tournament play, the Albin has never really caught on at the highest levels. Part of the explanation for this m ust be that it does not offer Black permanent structural compensation for his invested pawn. I nstead, Black acquires a lead in development (which may eventually be neut­ ralised) and various tactical chances, often directed against White's king. If White survives Black's early burst of activity. and there is no compelling reason to believe that he should not, he can look

·forward to a middlega me with extra material and/ or distinct counterchances of his own against the black king. The line I recom mend from the d1agra m 1s: 4 zt:\fj llSc6 5 g3 (rather than 5 a 3 or 5 ll:lbd2), ulso avoiding the obscurities of Spassky's 4 e4 ll:lc6 5 f4. Since Black usually has to castle queenside in the Albin, the development of the white king's bishop to g2 can be a useful asset for t he future. Even if Black succeeds in recouping the sacrificed pawn at eS. the opening up of the h l -a8 diagonal for White's king's bishop combined w1th a while queen sortie (either to -a4 or 63) and an advunce of White's queenside pawns, can prove a senous threat to the black kmg on c8 or 68. The most exalted victim of the Albin in recent years was U S grandmaster a nd many times US Champion, Walter Browne. He lost, as W hite, to Mestel in the 1982 Interzonal at Las Palmas, but the final result says lit tle about the outcome of the opening phase, which was in White's favour.

Up to here this game could have been identified as a modern one between grandmasters. But the rash weakening manoeuvre intro­ duced with the text places it judged by contemporary Grand Magisterial standards - firmly in its 1 9th century contex t . Still, there is no reason that your opponents in club, league or weekend events should play like grandmasters, and the reader may well encounter such moves from his own prospective vict i ms. 14 . f5 must have been initially conceived as a means of blocking the b 1 -h 7 diagonal , but Black soon change� his mind and tries to use hi� f-pawn as a battering ram. Unfortunately, his pieces are inadequately co-ordinated to justify such ambition. .

H istorica lly, the Old I ndian was the prec u rsor of the Ki ng's I ndian, fa voured i n the late 1 9th cent ury and early 20th century by innovators such as Ch igorin ( when not adopting the Defence w hich bears his own name) and N i mzowitsch ( before he invented the defence which bears his ) .

An interesting psychological situation has arisen, and a common one in chess . The White assault has ended, but he is now one good pawn (plus one doomed pawn) ahead in material. So, White has to overcome Blac k's cou nterplay and adjust himself to a mental framework of consolidation, rather then aggression. Not everyone can handle such i mportant transitions!

At last Black recognises the futility of having developed the knight on d7, and decides to re­ route it to c6, from which square he can also threaten White's d4 pawn. Sadly, t hough, B lack has lost so much precious time in the opening that Kasparov can now floor him with a few well-aimed blows . Threatening to knock away the props of Black's d-pawn with g5.

I do not advise White to accept the Benko Gambit. After 4 cb a6 5 ba .txa6 6 lt::l c 3 d6 Black enjoys unhindered, harmonious develop­ ment, plus two open files to blast away at White's q ueenside pawns. The standard procedure to adopt when material ahead is to simplify towards the endgame, when the extra pa wn, or whatever, should grad ually tell. I n t he Benko this procedure is not foolproof, fo r exchanges often intensify Black'!> pressure against Whi te's a- and b-pawns, in the line of fire of a black rook operating from bl:l a nd the bishop from g7. I n addition, accepting the gambit encourages Black to play a whole stream of very natural moves, e.g. contmuing

from the sequence above: 7 lt::l f3 g6 8 g3 .tg7 9 .tg2 0-0 10 0-0 lt::l bd7 (1 1 9)

Black will now follow up with more easy moves, such as . . . 1ta5 and . . llfb8. I f you are playing in a tournament with chess clocks, it is helpful to be able to play so many black moves without thinking and know that you are proceeding actively and correctly. Bent Larsen once wrote with acu ity about this: "Some players find it boring to play the same first I 2 mo ves over and over again: others don't m 1 nd Some are even happy if they play t hese moves quickly, there is less danger of serious ti me­ pressure. (The nasty part bf me thinks this is why Benko likes the .

92 Benko Gambit

gambit - ten moves for a pawn !)." U S Grandmaster Pal Benko, chief propagandist for the gambit which bears h is name, is, of course, a notorious time-trouble addict. My solu tion, therefore, is to play 4 lt:lO!?, politely declining the Trojan pony on b5, and thus throwing Black more or less on his own resources. I have used this successfully in my own games, and, incidentally, felt very uncom­ fortable whenever I have grabbed the pawn. It is also the recent choice of Viktor Korchnoi, twice" challenger for the World Cham­ pionship. For more details on the Benko in general, see BCO, pages 104 a nd 105.

"Although we generally expect Korchnoi to take pawns that are offered to him, in the present game he prefers to avoid any sharp H ungarian theory. Better to leave the opponent to his own resources in a position where he is less comfortable." ( H artston in the Tournament Book).

A closer relative to the Old Indian than to the Modern Benoni, the Czech Benoni erects a solid, resilient, but ulti mately passive position. Black's main hope of active counterplay resides in exchanging the dark-squared bishops (B lack's king's bishop is severely restricted by t he fixed c5, d6, e5 pawn triangle) and then achieving a bn:: a kt hrough with . . . f5. If White is vigilant , however, both of these objcdives can be suppressed. The most c1 itixd8 7 f4! .ie6 (7 . . . �c6 8 fe .ie6 9 ..ig5 + \!i>c8 10 �f) is uncomfort able for Black, whose displaced king jams his rook communication; 7 . . . �d7 8 �f) c 6 9 ..ie2 f6 I 0 0-0 'tt'e8 I I gJ is a lso :!: and a tedious position for Black to defend) 8 lLl fJ lLld7 9 ..ie2 h6 10 0-0 lLle7 I I lLld5.

Speelman was that the situation was not at all clear, though i t must be said that Speelman is a man who would prefe r to start the game with a couple of minor pieces instead of his q ueen, and might, therefore, be biased. After a l engthy investigation, it has been established that White should play 1 2 1td2 ! here, to preve nt the black king's bis hop from checking on d4. The game D.Cramling­ Davies, played at Copenhagen 1 983, several months after my game with Agdestein, sadly demon­ strated what is the likely death­ knell of the black q ueen sacrifice: 1 2 . . . l!Jf6 ( 1 2 . . . ..te5 13 ..id3 l!Jf6 14 h3 0-0 1 5 b3 ! i.d7 1 6 a4 e6 1 7 llhel b 5 1 8 cb ed 1 9 ed lL! xd5 20 .ic4 l!Jf6 21 -.Pg I ±± Davies) 13 .id3 l!Jg4+ 14 �e2 0-0 1 5 h3 lL!e5 1 6 b3 .id7 (after 16 . . . f5 White m ust play 1 7 el1 but this is sufficient to keep his advantage) 17 a4 lla6 18 llac l llfa8 19 'it'f2.

Dutch Defence 1 d4 f5

/4} w

Capablanca once denounced the Sicilian Defence ( I e4 c5) as an opening which "leaves Black's position full of holes". There are many who believe that the Dutch, the mirror image of the Sicilian, is a considerably more dubious proposition. Indeed, t he move I . f5 stakes out some sort of claim over t he e4 square, and also prepares subsequent general activity by Black on the kingside. On the negative side, though, it is a gratuitous weakening move, which diminishes important support for squares such as e6 and g6, and it contributes little to Black's develop­ ment. A common way for Black to suffer an accident in the Dutch is to be deluded i nto the belief that .

.

1 ... f5 is an immediately attacking move. Frequent disasters have overcome Black players who have launched inadequately supplied kingside attacks, relying only on their queen, king's rook , king's knight and kingside pawns, for­ getting about their lines of com­ munication with underdeveloped q ueenside units. Usually, White can detonate the entire undertaking with a timely central thrust, based on f3 and e4, exposing all of the weak nesses in the black structure, especially in the e-file. Black has three systems in the Dutch - the Stonewall ( with pawns on d5, e6 and f5); the Fluid (pawns on d6, e6 and f5) and the Leningrad, where Black fian­ chettoes his king's bishop. All three are playable, if Black is cautious and avoids premature adventures, and it should be mentio ned that the Dutch has been favoured by Botvinnik , Bronstein and former B ritish Champion, Robert Bellin, who has written an excellent book about it. There are various odp tries

against the Dutch: the Staunton Gambit ( I d4 f5 2 e4!?); the Korchnoi Gambit ( 1 d4 f5 2 h3 ll:lf6 3 g4 !?); al ternatively, I d4 f5 2 .i.g5 or 1 d4 f5 2 ll:lc3 ll:lf6 3 .i.g5 . . . Here, though, I reco mmend t he solid, classical variation based on g3 and the fianchetto of White's king's bishop. One good reason for this (apart from the method's inherent sound­ ness) is that Black may in troduce his Du tch via 1 d4 e6, inviting the French Defence with 2 e4, but avoiding the exciting ideas· men­ tioned above. The Dutch is treated in BCO, pages 36-4 1 .

This defence positively invites W hite to set up a mega lomaniac pawn centre, which Black will then snipe at with guerilla shots, such as . �b4 1fh4 and . . . f5. While I was acting as Viktor Korchnoi's second in the World Championship semi-final versus Polugayevsky at Evian 1 977, I succeeded in persuading him to t ry out the English Defence in game 6 of their match.

The 1 d4 Oscars US G randmaster Andrew Soltis, chess correspondent of the New York Post, once asked me to nominate the ten greatest players of I d4. I never found time to respond to his question directly, but here, in my book devoted to I d4, seems the appropriate time and place to publish my list of the I d4 Oscars. I have given them in order, with one annotated game each to demonstrate their prowess. Of course, my list is controver­ sial. O bjections could be raised, for example, that Alekhi.'l e was also a major exponen t of I e4, or that the list should embrace Capablanca, Spassky, Tal, Polu­ gayevsky, Euwe, N ajdorf, Browne, Bogoljubow . . . . However, in his

world title matches Alekhine was a staunch adherent of I d4, while Capablanca, Tal and Spassky, for example, relied heavily on 1 e4 for their i mportant competitions. My choice of Kasparov for the number one spot, in preference to Alekhine or Botvinnik, also needs some explanation. My own feeling is that Kasparov's interpretation of I d4 blends icy efficiency and almost balletic artistry in a way that excels the achievements of his mighty antecedents. A t the mo­ ment, Kasparov's rating is 27 1 0, the world's highest, and I believe that, still only twenty-one, he has the capacity to equal, or surpass, Fischer's all-time rating Everest of 2780.

Black's snail-like plan is . . . a5, ... j.d7 and finally ... a4. Relying on use of the vacated e5 square to aid his defence. Securely squashing White's dream of breaking down Black's barricades with e5. Gligoric rightly condemns this as an "impulsive move". Not only does it undermine Black's influt:nce over f5 , it also exposes the g5 pawn to later tactical operations. Safer is 21 . . . c;i;>h8.

There is nothing wrong with 6 . . . c5, transposing directly into the N imzo-I ndian, where W hite no longer has recourse to 10ge2. Fischer used to enjoy playing this obscure line which blocks his own c-pawn, but several reverses ultimately persuaded him to abandon it.

Black captures with the pawn to maintain a foothold in the centre, thus discouraging white advances such as c4 or e4. H owever, the structure before us can be recognised from my chapter on the N imzo­ I n dian and it is one which is excellent for White. The point is

Samuel Reshevsky 135

16

that Black cannot ultimately prevent White from marching through the centre with e4; meanwhile, Black is unable to play quick . . . ..ta6, swapping White's k ing's bishop, which now stays on the board for some time representing a powerful distant menace to Black's king. f"3

Blac k's queen's bishop would exert more influence on the centre from b7. Another idea worth considering is 1 2 . . . �b7!? followed by . . . lt:ld6 and then . . . ..tb7 or . . . ..tf5. The standard 'Arabic' develop­ ment of White's queen's bishop, the most efficient method of bringing it into action on the kingside, or in t he centre.

An in teresting moment. I t should not be forgotten that White has two aggressive plans at his disposal, either e4 followed by e5 and a general advance of his kingside pawns, or g4 and then �g3, followed, perhaps, by g5 and f4, pushing Black back. Fischer must have been very concerned by the second of these possibilities and decided to stop it for good, but . . . h5 proves very weakening when White actually opts for plan A. New York GM Edmar Mednis recommends instead the con­ structive waiting move 16 ... •d7, and he is surely right.

Still threatening g4, so Fischer continues with remorseless logic to stop it. 17 h4 But now the h-pawn is hopelessly cut off from Black's lines of com munication. 18 llf2 •d7

1 -0 Black cannot protect c6, e8 and f7 at once. Few people have dispatched Fischer so decisively. Reshevsky has a phenomenal record, having beaten Lasker, Capablanca, Alekhine, Euwe, Botvinnik, Smyslov and Fischer. Of living players, only Botvinnik can surpass this achievement, but at the age of 73 Reshevsky is still playing, while Botvinnik quit competitive chess for good when he reached 60.

Korchnoi's choice of opening was su rprising, at the time; his i dea may have been to avoid. his opponent's excellent k nowledge of main line opening theory . Though Karpov's 3 . . . b 6 cannot be called a mistake, it may be a psychological error, si nce it allows White to create a position where Black has the bishop pai r but is otherwise passive. 3 ... c5 is more combative, leading to u nfathom­ able complications after 4 e3 'lrb6 5 lll b d2 'tlrxb2 6 .id3 d� 7 c4 1fc3 8 �e2! � bd 7 9 'ira4.

I would be tempted by exchange sacrifices based on 10 llxc3, offering the queen's rook for Black's strong king's bishop, but somehow I doubt that such concepts can be proved sound.

With ten years of hindsight, Black's best course at this stage was fou nd to be 1 2 . . . � xc5 1 3 0-0 �e4 14 1fc2 �d6 with a complicated position if White retreats h is king's bishop.

Black's position has become quite wretched as a result of his error on move 1 3. His king has no safe refuge, and the pawn on f5 is doomed if White sets about besieging it. The best way of solving the problems is Mednis' suggestion: 1 7 f4 ! ( if Black waits White may fix the pawn on f5 with f4, and t hen pick off f5 at his leisure) 18 ef j,d6 followed by 0-0-0. A strict blockade by Black's queen and bishop on c5 and d6 will shut White's k.ing's bishop out of play for some time, and with opposite bishops on the board, White will experience difficulty in converting his extra pawn into a win. o o •
