Introduction Emanuel Lasker once joked that his only contribution to opening theory was the observation that knights should be developed before bishops. The Four Knights opening illustrates this thesis in ideal fashion. Both sides first place their knights ac­ curately, and then think about what to do further. Joking aside, if such a plan is completely harmless, then how come this simple plan has attracted the interest of such serious players as Shirov, Sutovsky, Nunn, Bacrot, Rublevsky, Short, Motylev and Naer? And, incidentally, what is it that unites these players? This is clear - a cre­ ative approach to the game, and a constant willingness to enter into the battle. In recent times, computers have gone a long way towards proving the truth of the axiom that 'Chess is a draw' , steadily analysing out many complicated lines, and ending up with the assessment '00:00'. The silicon monsters have established par­ ticularly depressing dead-ends in lines such as the Petroff Defence and the Berlin Wall variation of the Ruy Lopez. But, surprisingly, things are by no means so sad in the Four Knights. Looking through recent games in the Rubinstein Variation 1 .e4 eS 2 . lbf3 lbc6 3 . lbc3 lbf6 4.�b5 lbd4 S .�c4 �cS 6 . lbe5 , one rather unexpect­ edly comes across a remarkably large number of white queen sacrifices, although whether these are correct or not is a different question. It is interesting to compare this trend, which occurs in the supposedly peaceful Four Knights, with the situation in its allegedly much sharper close relative, the Belgrade Gambit, which is highlighted in a separate chapter at the end of the book: Chapter 7. In the majority of variations of this system, which lie off the beaten track of current theory, the play results in an equal ending , unless Black plays in the style of the old masters, and fearlessly accepts all of the sacrifices ( 1 .e4 eS 2 .lbf3 lbc6 3 .lbc3 lbf6 4. d4 ed4 S . ltJdS ltJe4? ! ) . If White is prepared to play the Four Knights , he must also be ready to face vari­ ous attempts by Black to avoid this, on the third move. The first chapter of the book is devoted to these lines. It looks at the variation l .e4 eS 2 . lbf3 lbf6 3 .lbc3 �b4: White does not want to allow the Petroff Defence, but Black wants to avoid the Four Knights ! Later, we examine Black's attempts to avoid the Four Knights on move three, after 1 .e4 eS 2 . lbf3 lbc6 3 . lbc3 , the most popular method being 3 . . . g 6 . Chapter 2 looks at various rare fourth moves for Black, such a s 4 . . . �c5 , 4 . . . a6 and 4 . . . �d6 ! . The last of these was not even mentioned in John Nunn's book New Ideas in the Four Knights, published in 1 9 9 3 , since at that time there were no signifi­ cant practical examples. However, in our day, the system with 4 . . . �d6 enjoys a de­ gree of popularity that compares with the main lines. Chapter 3 and 4 are devoted to the classical l .e4 eS 2 .lbf3 lbc6 3 .lbc3 lbf6 4.�b5 .tb4, which is characterised by a complicated strategic battle, with a small advantage for White. (However, Karpov, in his best years, several times outplayed his opponents as Black in this line, showing that here, the knights are not inferior to the bishops, if they are handled by a player of the highest class.) 7

T h e F o u r Kn i g h ts Gam e

In Chapter 5 and 6 , we look at Akiba Rubinstein's immortal variation, 4 . . . tLld4. Note that after 5 .�a4 �c5 or 5 .�c4 �c5 , White is not obliged to capture on e5 , although it is in precisely these variations that we can witness the amazing adven­ tures and miracles for which we love chess. To be quite frank, it is the recent games in this variation that inspired the author to produce the present work. Chapter 7 looks at White attempts to squeeze water out of the stone that is the Belgrade Gambit - not an easy task, it must be said. Ju ly-Oc to b er 20 I 0 A n drey O b o dc hu k

The Three Knights' Opening

This modest-sounding title actually conceals a whole series of different set-ups, be­ ginning with l.e4 e5 2.tt:lf3 tt:lf6 3.tt:lc3 (diagram left) or 2...tt:lc6 3.lLJc3 (right) , which Black can bring about by the simple expedient of not playing the most natural move, i.e. by not bringing his second knight to its most natural development square.

1.1 The Anti-Russian Gambit

In this section, we are not concerned with any form of Russophobia - it is just a question of move-orders, in which Black offers his opponent the chance to enter the Russian Game, i.e. the Petroff. White in his turn announces that he would prefer to battle in the Four Knights, and then Black declines this in­ vitation, and by means of the move 3...1tb4 , - after l.e4 e5 2.tt:lf3 lLJf6 3.lLlc3 - heads into a variation which is formally part of the Three Knights.

It should be noted that this line is not to the taste of all Russian Defence players, since, despite its outwardly unassuming character, it generally promises White a small, but stable advantage, where the main question is whether Black can make a draw or not. Maybe for this rea­ son, such leading practitioners of the Russian Game as Kramnik and Gelfand prefer in this position to go into the Four Knights.

Some theoreticians claim that 8 .tt::l f4 is more accurate, not allowing . . . d7 -dS . But the top players have their own the­ ory. Thus , in the game Svidler­ Gashimov, Sochi tt 2 0 0 8 , White began with 8.c4: 8...d6 9.0-0 tt::ld7Worthy of attention is 9 . . . tt::l c 6 I O .�e3 �fS I I . .l:!.e i h6 I 2 .tLlf4 tt::l f6 .

But there are some differences: White has two bishops and Black has already castled kingside, whereas in the analogous line of the Russian Defence, he quite often castles queenside. White has yet to deter­ mine the position of his own king, so the I8

question arises whether he can castle queenside and play on opposite sides? 6. 7.

Nihilism in the opening

Chess can be played in different ways. There are many chess players who pre­ fer less explored byways, trusting in their ability to invent something not known to the professionals, who spent day and night exploring long computer variations. In this section, we will look at a couple of examples of this rather nihilistic approach to opening prob­ lems , in the shape of the move 3 . . . d6 (after l .e4 eS 2 . tLlf3 tbc6 3 . ttJc3 ) . Its clear drawback is that White has carte blanche to choose the set-up for his pieces.

After 5...g6 we reach a position, similar in spirit to the line examined in section I . 4 of the present book. But there is also a fairly significant difference : in the main variations of this line, Black quite often gets in . . . d7 -dS in one move, so the early 3 . . . d6 may turn out to be a loss of a tempo.

This is what Grandmaster John Nunn wrote in his book on the Four Knights : 'Studying the published theoretical sources suggests that this line is very bad for Black, and this is probably the case, although White has to show some accuracy' . Admittedly, this deadly view is not shared by everyone, most notably the Grandmaster from Lvov, Oleg Romanishin. He has played this line for many years, with good results. The truth , as so often , probably lies somewhere between the two extremes. Game No 6 [C46] Pedzi.ch,Dominik Romanishin,Oleg Koszalin 1997 (5)

1.4 Kingside Fianchetto Variation 1.e4 eS 2.tt:lf3 tt:Jc6 3.tt:lc3 g6

Anyone who wishes to play the Four Knights Opening needs to be prepared for this, one of the most common lines in the Three Knights , which is charac­ terised by the fianchetto of Black's king 's bishop. It is employed most often by stronger players against weaker op­ ponents , because it generally leads to complicated, sharp positions. White must work hard to achieve an opening advantage. Practice shows that only by castling queenside, in various different forms , can White pose his opponent real problems. This does not exclude less ambitious set-ups, such as in the style of the Italian Game, with moves such as �c4, d3 , a3 and 0 - 0 . However, in this book, we will look at attempts to gain the advantage after the initial moves 1 . e4 eS 2 . tt:lf3 tt:lc6 3 . tt:lc3 g 6 4.d4 exd4 and, a s a rule, involving queenside castling. 37

The Four Knights Black avoids the main line on move 4

The reputation of the variations ana­ lysed here varies from the dubious ( 4 . . . a6? - see Game 1 6) to the more or less play­ able ( 4 . . . �cS - see Game 1 4- 1 5 ; incidentally, this move was played successfully by the great Morphy ! ) to the perfectly solid ( 4 . . . �d6 ! ? - Games 1 7 - 1 9) . It is interest­ ing that the theory of the last move has only been formed in the last 1 5 - 2 0 years; one only has to recall that in John Nunn's book New Ideas in the Four Knights ( 1 9 9 3 ) this line was not mentioned at all. This i s no surprise - to respectable masters o f the last century, it looked rather strange to place one's bishop in front of one's pawns in this way. But ' tiempi cambi' , as they say!

Once it became clear that there was no direct refutation of this rather extrava­ gant-looking move, it started to appear occasionally even at the very highest level. Even so, the great majority of very top-class players, cherishing every tempo (it is clear that the bishop will have to move from d6) are still not rushing to in­ clude this move in their repertoires. In this section, we will look at those di­ rections in which the strongest players have ventured in recent times. It is clear that the nature of this system has much in common with closed variations of the Spanish, in which plans, schemes and assessments are often more impor­ tant than concrete variations. •.•

In the notes to the following game, we see a plan which has become popular lately, involving the modest move d2-d3 . To preserve the Spanish bishop, White is prepared to lose a tempo. And why not, indeed; after all, the bishop on d6 will have to move again.

The Four Knights Game

The following variation is somewhat unique. Its nearest relative is the line seen in Game 24, Nisipeanu-Ponomariov, where similar ideas, with colours re­ versed, are adopted by Black. But it is well-known that employing black ideas with colours reversed often fails to bring White the benefit he might expect. Such is also the case here: the manoeuvre 7 .tDe2 promises White very little, whereas the analogous knight jump by Black 7 . . . tDe7 gives him good practical results.

By comparison with the games Shorr­ Speelman and Acs-Greenfeld, quoted above, White has saved a tempo on bringing his bishop to b3 . However, it is not yet clear whether this brings him anything real.

i.b5xd7?!

Illogical. Almost any sensible move looks better, for example: 1 4.a4 ! ? c6 1 S . ..tc4 ..te6 1 6 . ..txe6 'iVxe6 1 7 .a5 with a clear advantage, or 1 4.h3 �xbS 1 5 .'i¥xb5 tt::l b d7 1 6 .'iYc6 ( 1 6 .'tWa4 ! ?) . 1 4. 1 5.

This move has not been met in tourna­ ment practice. It is not easy for Black to escape from the pin. Thus, it is quite dangerous to play 1 2 ... g5Maybe Black should resort to the tried and trusted Metger method with 1 2 . . .'iYe 7 , al­ though in this case, White will retain some initiative. For example, 1 3 .h3 (preventing . . . �g4) 1 3 . . . axbS (the typi­ cal 1 3 . . . ti:Jd8 1 4.'ir'd2 does not solve the problem, as 1 4 . . . ti:Je6 fails to l S .dxeS ±) 1 4.'ir'd2 , and it is still difficult for Black to escape from the pin. 1 3.tt::lxg5 ! ?

Chapter s

The Rubinstein System

This chapter deals with White's replies to 4 .. .lt::ld4! (after l .e4 e5 2.tt::l f3 tt::l f6 3.tt::l c 3 tt::l c 6 4.�b5) . Black's fourth move was popularized by Akiba Rubinstein at the be­ ginning of the last century, although it had been played since at least 1 8 7 6. Nowa­ days it is considered Black's best method of equalising.

In the search for an initiative, White has tried many moves, but none of these en­ sures him any significant advantage. The author felt it made sense to divide this chapter into two. In the first, we ana­ lyse variations which have not caused Black too much trouble in recent years , and have largely lost their topicality. 5.1 The variation 5.tt::l xd4 exd4 6.e5, traditionally considered a reliable way for White to duck out of the battle, is considered in Game 3 6 . As a main example, we have chosen the game Priborsky-Romanov, in which Black managed to overcome the drawish tendency of the variation and, with the help of a striking long king march, to win an interesting bishop ending. 5.2 The move 5.tt::l xe5! ? is not without a drop of poison, as demonstrated by the quick white win in the game Short-l' Ami (Game 3 7 ) . 5. 3 The so-called 'Anti-Rubinstein' , beginning with 5.0-0 , brought White good results in the 1 9 9 0s. In our day, this line has lost its former popularity, as reliable equalising methods have been found for Black. Nevertheless, here too there are many hidden reefs, which require accuracy from Black, if he is to avoid shipwreck (Game 3 8 , Hirscheider-Weidemann, ending with a nice white combination) . 5.4 We end this chapter with Games 3 9 -49 , dealing with the line l .e4 e5 2.tt::l f3 tt::l f6 3.tt::l c 3 tt::l c 6 4.�b5 tt::l d4 5 .ta4. Decades ago, this was considered the main means of fighting for an advantage. Motylev's striking victories over Shirov and Grischuk, at the start of the 2 0 0 0's , drew the attention of many lovers of sharp play, •

but chess fashion changes, and in recent years, most supporters of the Four Knights have switched their attention to S . .tc4. Even so, the positions reached in this line are complicated and still little-studied, and many tactical tricks and strategic subtle­ ties remain hidden here. In No 43, Shirov-Hansen, where Black played 6 . . . 't!Va5, White did not exploit all ofhis chances in the opinion of the author. The fashionable move s . .tc4 is examined in detail in Chapter 6 .

'Because of the weakened position of his king, White can hardly play for a win' L Kritz. I think this judgement is only partly correct, because for the moment, and indeed for the rest of the game, the white king is not actually attacked...

The forced play is over. White has three ( ! ) extra pawns, but one cannot conclu­ sively pronounce the position in his fa­ vour. His king is chronically weak, his heavy pieces are not playing, whilst the opposite coloured bishops strengthen the black attack and add to White's headaches. 20. l:i.h1-h2 2 0 . .ie3 does not promise an easy life, eg. 2 0 . . . l:i.b8 2 1 .b3 �g4 2 2 .�g2 l:i.bS 2 3 .�g3 .ihs 2 4 . l:i.h3 l:i.fs 2 s .�g2 l:i.e6 2 6 .�h2 �xf3 and White is in trouble. 20.

It is hard to judge the play of players, equipped with more powerful comput­ ers than the author. However, from the viewpoint of a carbon-based player, Black's last move looks rather abstract. I would prefer to attack something : 2 0 . . . l:i.b8 2 1 .b3 l:i.bS 2 2 . .ie3 l:i.hS , or 2 0 . . . 'iff6 2 1 .�g 1 .td.b8 2 2 .l:i.b 1 l:i.b6 2 3 .h5 �b7 .

Black definitely has compensation for the pawn: his minor pieces are better placed. The pawn on f3 is under perma­ nent attack, and it is not easy to evacu­ ate the white king. However, the assess­ ment is not all one-way; a pawn is a pawn, White has no clear weaknesses, and there are no forcing variations, leading to a black advantage. The positi­ on is rich in playing potential. I will of­ fer a fragment of my analysis. 1 56

Afterword This book started out as a small opening booklet for my pupils. I included the most interesting games on the subject, and my own analyses and assessments, until it grew into the solid tome it has now become. At one moment, I received the latest issue of a certain chess magazine, and de­ cided to analyse the game Sutovsky-Naiditsch, Wijk aan Zee 20 10, simply because I admire Sutovsky 's creative play, and to include the results in this work. However, I just could not convince myself that White has sufficient compensation for the queen in the critical position, and so did not feel able to recommend this adventure to my pupils. The more I delved into the position, the less I understood what was going on. Time after time, the silicon monster ruthlessly denied my desperate attempts to prove that White was OK, but then, around move 30-40, it would suddenly change its mind. Eventually, after about two weeks of Sisy phian effort, I surveyed the result­ ing 30-page file of crazy variations, with all kinds of material imbalances, and I realised that it was simply impossible to make full sense of this cross-bred offspring of human and computer brains. As Goethe's Faust put it, 'Da stehe ich ein armer Tor und bin so klug, wie auch zuvor...'- 'Here now I stand, poor fool, and see I' m just as wise as formerly.' 'Yes, but you are no Sutovsky, and are rated 300 points lower' , I said to myself, bitterly. Nonetheless, I have included in this book some of the discoveries from that file. ·

Does the Four Knights give White real chances to fight for the advantage? No, of course not! But it does guarantee a lot of adventures, and adrenaline rushes, espe­ cially if both sides are disposed to a sharp fight! November 20 10 Andrey Obodchuk
