Introduction

This work presents a detailed and analytical account of the Petroff Defence. Part One consists of nine chapters and deals with index C42 of the Petroff Defence, according to the ECO (Enc.vclopaedia (J{

Chess Openings) classification, i.e. with all White's possibilities on the third move, with the exception of 3. d4, which is the subject of Part Two. Part Two, consisting of seven chapters, considers the continuation 3.d4 (C43 -ECO), introduced by the Russian player Alexander Petroff. Each chapter begins with an overview in which the author expresses succinctly his view regarding the present state of the system under consideration, and gives recommendations for its investigation from the point of view of both White and Black. Then follows the theoretical section, which is arranged in accordance with ECO format. Here the Chess Informant code system has been adopted. For the sake of convenience, all variations and corresponding references are numbered successively, and not by chapter. The book contains twelve annotated games, which illustrate the author's approach to the most important problems in the treatment of the given system. The critical positions of each game are illustrated in diagrams. This allows the use of the games for training, since one can attempt to analyse the position in the diagram, and then consult the book for the correct answer. Each chapter of the book contains specially selected exercises. These illustrate differ-

9

ent positional methods, typical tactical blows, and some instructive middlegame and endgame points. There are 244 such exercises in this book. The author would like to note here that some of these positions allow more than one solution. The overviews, training positions, and annotated games are designed mainl y for cl ub players who are intending to learn a new opening. I hope, however, that more experienced players will also find this book interesting and useful. While working on this book I used various sources, of which the main were: Chess In

formant 1-64; Encyclopaedia of Chess

Openings (2"d ed.); ChessBase Magazine

1-49; New In Chess Yearbook 1-3 7; Fidechess, and the monographs: Russische

Verteidigung and The Petroff Defence by Forintos; La DeFence Petrov by Karpov. I wanted to write a good book, and although it does not reveal all my knowledge of the Petroff Defence (since I still employ this opening in practice!), I have tried, as far as my understanding allowed, to give correct and thoughtful assessments to a large number of systems. It goes without saying that in the course of time many lines in this book will be corrected, refined, or even refuted. The reader is encouraged not to follow the author blindly, but rather to approach the text critically. I would certainly be grateful for any comments or suggestions that would improve the work.

Part I

Chapter 1

1.1.1. Overview

This chapter deals with various deviations from the main systems on the third and fourth moves. The gambit 3.�c4 tiJxe4 4.tiJc3 ( -1-2) was Morphy's favourite weapon against the Petroff Defence. Black can switch to the Four Knights Opening after 4".tiJc6 (CSS/ S). The critical move is 4".tiJxc3, although Black must play carefully (position 2). It is interesting that Morphy himself preferred not to accept the gambit and used to return the pawn by S".c6 (-2). The solid continuation 3.tiJc3 allows Black to switch to the Four Knights Opening. This book considers only the move 3 ... �b4, which has its own importance. Black, as it were, is playing the Ruy Lopez a tempo down. Nevertheless, this line looks reliable enough for Black. At the same time, by continuing 4.tiJxeS White normally obtains the bishop pair, and as modern practice shows, can hope for a small but stable advantage (positions S & 6). For those players who want to play this system with White, it is recommended that they see how the ensuing positions are treated by Shirov.

1 1

The system 3". tiJ xe4 (-7) can be successful only against an unprepared opponent. The Cochrane Gambit is a boon for those players with a penchant for adrenalin (-8-II, positions 8-10). For the sacrificed piece White gets two pawns and the initiative. Through the efforts of the Latvian master Vitolinsh this system has become popular. And yet, in my opinion, the gambit is only 90% correct; it hardly makes sense to try it against strong defensive players. Among the various systems of defence, the most promising are S".�e7 (-9) and S".cS (-l OII), though future practice might change this assessment. The Paulsen Variation (4.tiJc4) does not seem to be too dangerous for Black (-12-14; positions II-IS). On the other hand, the knight's position on c4 (or e3 where it often moves) introduces original motifs into this type of position (position 14). This line can well suit those players who do not like to spend much time studying complex theory, and are looking for a handy system for White instead.

Chapter 2

1.2.1. Overview

There are several ways for White to deviate from the most popul ar continuation S . d4 . This chapter wil l consider all the deviations, except S .Wfe2 (see Chapter 3 ) .

After S .d3 ctJ f6 6 .d4 B lack can transform the game into the Exchange Variation of the French Defence (CO l ) by 6 . . . dS . We wi l l confine our analys i s in thi s chapter only to those l ines which are typical of the Petroff Defence. It i s important to note that 6 . . . !ibe7 should be sufficient to equalise (I S ) . This flexible continuation yields Black various possibil ities (-positions 1 6, 1 7 ) .

The system S . ctJ c3 (- 1 6- 1 9) leads t o complicated and interesting play. Sharp positions with the kings castled on opposite sides are typical of thi s l ine. In my opinion, the best idea for B lack i s to exchange on c3 (- 1 8- 1 9) . Although nowadays B lack

42

usually manages to solve his opening problems, he needs to play thi s l ine with great prudence and attention. It is not by accident that Vladimir Kramnik in a decisive game against the world champion Garry Kasparov, Grand Prix (New York) 1 995, chose thi s variation and was very close to winning. The most appropriate way to start studying this system is to analyse game I and positions 1 9-32 . The idea of the continuation 5 .c4 (-20-22) i s to impede the advance . . . dS . Although the normal developing move S . . . !ibe7 has proved an acceptable choice for B l ack, lately he has often been sticking to 5 . . . ctJ c6 (-22) . This move allows him to avoid the l ine 6 .d4 due to the great effectiveness of the advance 6 . . . dS (- 1 48 ; see also position 37 ) . The continuation 6 .ctJc3 leads to variation 2 1 .

The system with queenside castl ing is White ' s most aggressive option. In this position he faces the following dilemma: where to develop his dark-square bishop at e3 or f4? Black's plans are conditioned by the posit ion of White ' s dark- square bishop. After 7. �e3 the black knight has the opportunity to move to e5 . If White takes control of this square, by developing his bishop at f4, then B lack should normally direct his knight to c5 . 7.�e3 tLl d7 ! ? 8.�d2 0-0 The order of moves chosen by B lack gives him the additional possibil ity after 8 " . tLl e5 9 .0-0-0 (or 9 . tLl d4 c5) tLl xf3 of switching to the set-up with queenside castl ing ( 1 28/ 7 " . tLl d7 ) . 9.0-0-0 tLl c5 As stated above, 9 " . tLl e5 is a plausible alternative .

Chapter 3

1.3.1. Overview

This chapter turns to the analysis of the system 5 .Vf1e2. This l ine has a peaceful reputation. A serious problem when studying this system results from its frequent use in ' composed ' games ( i .e . , those games, in which a draw is agreed beforehand) . Such games misinform rather than c larify the subtleties of this system, which in fact is very complicated and rich in content. It has belonged to the opening repertoire of practically every world champion (some examples from their practice can be found in positions 40-48) . White tries to make use of his advantage in development (sometimes he has two extra tempi ) , but B lack 's position i s solid and free of weaknesses. Correct play by both sides yields White only a minimal advantage. The main starting position of the system occurs after 5 .. :lIjj e7 6 .d3 lLl f6 7 .ig5 . The l ine 7 . . . ie6 (-23-25) leads to a compl icated middlegame, giving White the bet-

71

ter chances . Some tactical features of this variation are considered in positions 3 8-40. B lack 's most prudent strategy is to push for an endgame, where his s l ight delay in development is less dangerous . 7 . . . Vf1xe2+ has proved a rel iable continuation (-26-28) . In order to neutral ise White ' s pressure on the e-fi le , B lack often sends his knight to e6 via the route paved by Petrosian in his 1 969 match against Spassky : lLl b8-a6-c7-e6 (-27-28) . The Milner-B arry Variation 7 . . . lLl bd7 i s also a reasonable choice, especially if Black is bent on a more complicated struggle. It is not by chance that this line was Bronstein ' s favourite weapon. White ' s hopes of gaining an advantage are often associated with the advance of his knight to b5 (positions 49-50) . General ly speaking, the 5 .Vf1e2 system is especially advisable for those players who l ike and know how to play the endgame.

This chapter wil l summarise various marginal possibil it ies for both sides on moves 5-6 and deviations from the main lines of the Staunton System (6 . . . id6 7 .0-0 0-0 8 . c4 c6) . The system 5 . . . ie7 6 .id3 ttJ f6 ( -32-34) leads to posit ions i n which White maintains a space advantage . Here he often has an extra tempo in comparison with the line 5 .d3 (- 1 5 ) . It i s advisable for B lack to try to ease his defence by exchanges (-posi t ion 53 ) . In general , despite the absence of weaknesses in B lack ' s position, White has various ways of developing his initiative (-positions 54-57) . 5 . . . d5 l eads to a symmetrical pos i t ion , where Black has made an extra move compared with his opponent . Although the black knight i s centrally placed and protected by the pawn, its position is sti l l vulnerable . White can exercise both the undermining of the centre by c2-c4, and the direct attack on the knight by id3 and i:%e 1 or W1e2 . It turns out that the ' extra' move creates additional problems for B lack . The main di lemma that he faces in the immediate future, is whether to withdraw his

knight to f6, reconci l ing himself to the loss of a further tempo, or to try to maintain his knight at e4 . The Staunton System (6 . . . id6) has become very popular in the last few years . B lack places his bishop in an active position, aiming at White ' s kingside (-positions 60, 63, 65 ) . The main drawback of this set-up is the weakening of the d5 -pawn. The attempt by White to undermine the centre before castl ing by 7 .c4 (-positions 5 8-59) i s somewhat untimely because of 7 . . . ib4+ (-3 5 ) . The Marshall Gambits 7 . 0-0 ig4 (-36) or 7 . . . 0-0 8 .c4 ig4 (37) do not yield B lack equal chances, according to modern theory. The corect way to gain an advantage for White was demonstrated in Alexander -Mallison, Brighton 1 93 8 (-position 62) . 8 . . . ie6 i s an interesting alternative to the main continuation 8 . . . . c6 ( -39-4 1 ) . This line is analysed in detail in the second part of thi s chapter (-also positions 63-70) . The game Kamsky-Yusupov, Ti lburg 1 992, in which White attained a slight, but enduring advantage (-4 1 ), can be regarded as a good example of White ' s play in this variation.

Chapter 5

1.5.1. Overview

This chapter consists of two parts. The first covers White 's various possibilities on the 9th move (!::le I , Wlc2, CLlc3) , except for the continuation 9 .cd, which is the topic of the second part. The difficulty in studying the vast amount of material is intensified by possible transpositions of moves . For instance, the modem 'tabia' of the system occurs after both 9.lUc3 ctJxc3 l O .bc ig4 I I .cd cd, and 9 . cd cd l O .ctJxc3 CLlxc3 l 1 .bc. In such cases we do not treat these lines separately; in part icular, both of the above-mentioned lines are analysed in the second part of this chapter, since the author considers the move order used in the second part to be more precise (thereby White avoids the l ine 1 0 . . . dc (-52-55 , game 2) . The recent practice of this variation does not promise White a big advantage. Thus , after 9 . !::le I , B lack has three satisfactory continuations : 9 . . . ig4 (-42, position 7 1 ) , 9 ... !f5 (-43), and 9 . . . !::le8 (-44, position 73) . 9.1!f1c2 leads to complicated variations . Black has a choice between protecting his knight by 9 . . .f5 or sacrificing a pawn after 9 . . . lUa6. According to modem theory, in the second case B lack gains sufficient compensation (-46-47 , posi t ions 7 5 - 7 6 ) . If White declines the sacrifice by 9 .a3 , then 10 . . .f5 I I . CLlc3 leads to a position which can also occur in the line where B lack chooses to protect the pawn (9 . . . f5 l O .CLlc3 ltJa6 II .a3) . For the sake of convenience,

1 1 5

this line is treated together with the variation 9 . . . CLla6 (-48-49) . The ensuing pawn structure determines the character of the forthcoming struggle. White usually tries to occupy e5 and to develop an initiative on the queen-side, while Black seeks his counterchances on the kingside (positions 77-78) . White has the better chances, but the game is double-edged. The alternative l O . . . ig4 gives the game a different shape (positions 79-8 1 ) . White has not been able to gain an advantage after l 1 .c5 ic7 1 2 .CLle5 ixe5 1 3 .de CLlxc5 , or in the case of an immediate 1 1 .CLle5 . 9 .CLlc3 is a less popular continuation nowadays due to the variation 9 . . . CLlxc3 l O .bc dc (-game 2). Note B lack's precise defence in the recent game Kamsky - Bareev, Linares 1 993 (-54) . The second part of this chapter deals with the ' tabia' of the Staunton S ystem (9.cd cd l O.CLlc3 CLlxc3 l 1 .bc ig4 1 2 .EJ:b 1 ) ( -game 3) . Black has two main continuations : l2 . . . b6 and 12 . . . CLld7 . In the first case, as the games Short-Timman, Hilversum (ml4) 1 989 (positions 85-86) and Oll-Akopian, Manila 01 1 992 have shown, l 4 .c4 is not dangerous for Black (-57) . Instead, variations with the exchange sacrifice 1 4.h3 a6 1 5 .hg ( l 5 .!::lxd5 ! ? -58) seem to be more promising for White . The ensuing positions are very complex and require thorough preliminary preparation. A study of the games Short - Gelfand, Brussels, cml7 , 1 99 1

(-game 3 ) and Ivanchuk - B areev, Linares 1 993 (-positions 87 -89) can help to disclose the subtleties of the variation. Very interesting positions occur after 1 2 . .. ctJ d7 . After 1 3 .h3 ( 1 3 .a4 ! ? -423) ihS White has tried three continuations. The first of these, 1 4J:%xb7 (-62), leads to a complicated situation in which the white rook is separated from its main forces. The less adventurous 1 4 .a4 yields Black counterplay on the c-file (position 9 1 , -63) . The sharpest move 1 4 .E1bS requires especially careful play by B lack. The continu-

1 1 6

ation 1 4 . . . ctJ b6 l S .c4 ctJ xc4 requires practical testing (-64) . The acceptance of the sacrifice l S . . . dc leads to a situation where B lack must pay attention to the various tactical threats of White, who can exploit the active position of his rook on the fifth rank (-positions 92-96) . The Staunton System was very popular in the late eighties and early nineties, when it was practised by many leading grandmasters . It i s sufficient to mention the names of S hort, Timman, Anand, Ivanchuk, Kamsky, Salov and Bareev.

Now Black is aiming after tg6 to drive the white queen away from its active position. However, by the standard advance of his f-pawn White completes the manoeuvre begun with 1 2 . lt'l g5 and reinforces his pressure on the kingside. After the text

This i s the most dynamic continuation. White immediately attacks the b-pawn and

plans to threaten the dS-pawn after I'M. Such sharp play is fully j ustified by the existing pawn structure . Indeed, if Black completes his development, it will be easier

for him to attack the c3-pawn along the c

file, than for White to play against Black's major weakness - the dS-pawn. The text

move also contains a hidden tactical sub·

tlety. It seems that it would be convenient for White to include the moves 1 2 .h3 �hS. but in this case after 1 3 .gb 1 b6 1 4 J1bS

B l ack repl ies 1 4 . . . a6 I S . gxdS ixh2+ 1 6 . l2l xh2 iWxdS . After the immediate 1 2.gb l b6 1 3 .gbS a6 (or 1 3 . . . l2lc6) 1 4.Elxd5

unprotected and White gains two minor

pieces for the rook.

12 ... b6 Regarding the alternative 1 2 . . . ctJd7 , see positions 90-96 . Note that B lack should not underestimate the threat of �xh7 + . Thus, i t is bad t o continue 1 2 . . . 'lMfc7 ? 1 3 .h3 �h5 ?, as after 1 4 .�xh7+ White develops a winning attack ( l 4 . . . ct?xh7 I S . ctJ gS+ ct?g6 1 6 .g4) . 13.Ei:b5 �c7 14.h3 The complications after 1 4.c4 dc I S .�e4 ILlc6 !

The interesting continuation I S . 1'lxd5 1WxdS 1 6 .hg was tested i n the game Dvoiris - Rozentalis , L vov 1 990. In this case White obtains a mobile centre, but Black has no problems in completing his development with 14 . . . ctJ c6 followed by 1'lad8 (-58) .

After 1 9 . ctJ gS ? ! (with the idea of 1 9 . . .

Instead 1 9 .c4 ! ? l=1xg4 20.cd �f4 ! deserves consideration, when White obtains sufficient compensation for the sacrificed exchange (-60) . The text move is risky, since White blocks in his bishop. At the same time Black must be very attentive to his opponent' s attacking possibilities . One of his problems is the development of his knight. Black decided to prepare the move cuc6 with 19 . . . iWd6, but this allowed White ' s knight to settle on e5 . 1 9 . . . l=1a3 ! would have been stronger, activating the rook and attacking the weak c3-pawn. The significance of the rook's activation becomes apparent after 20 .c4? l=1xf3 2 1 .gfiWd6-+ (Gelfand, Kapengut) or 20.cu d2 iWd6 2 1 .g3 l=1eTt (intending cu c6) (Gelfand, Kapengut) 22.c4?? l=1xg3+ -+ , and the weakness of the c3 -pawn is felt after 20 .g3 iW c S + (Gelfand, Kapengut) 2 1 .

In order to activate his forces, Black sacri· fices a piece . It should be noted that thi�

is only feasible because the h6-bishop is locked in. 22.CtJxc6 The intermediate 22.f5 ! ?

The position has simplified, and Black needs only to avoid allowing White to create a passed pawn, and to pay attention to

mate threats . These two tasks are not too difficult for Black, who is effectively the exchange up.

Chapter 6

1.6.1. Overview

This chapter consists of two parts . The first considers Black's attempt to save time on the move . . . :!e7 for the sake of the immediate attack on the centre by 6 . . . ct'lc6 and 7 . . . ig4. When studying this system from the point of view of Black, one should note that White can include the moves �e 1 :!e7 and thereby switch to the variations of chapter 8 . As practice has shown, the variation 9 . cd does not promise White an advantage (positions 97-98 ; -69) . The pawn sacrifice 9 .l/Jc3 is more dangerous for Black. In this case 9 . . . :!xf3 1 O .'Wxf3 ct'l xd4 1 1 .'We3 (-70-7 1 ) l eads to very sharp play. White is capable of developing a strong attack, although Black has sufficient defensive resources at his d isposal (-positions 99- 1 00) . Another queen move - 1 1 .'Wh3 - would appear to create more serious problems for B lack. He was unable to solve his defensive problems in the game Kupreichik-Yusupov, Minsk USSR ch 1 987 (-game 4) , as well as in two correspondence games: Nadanian-Sharbato v, 1 993 and Pletanek -Dufek, 1 992 (position 1 0 1 ) . Possibly, the best continuation

1 61

is 1 1 . . .dc 1 2 .:!xc4 :!e7 1 3 .:!g5 'Wc8 as suggested by Forintos , yet even in this case White's initiative is very unpleasant. Nowadays the 7 . . . ct'lc6 system is in a deep crisis . The second part of this chapter deals with Black's various possibilities on move seven, except for the main continuation 7 . . . ct'lc6. The 7 . . . ct'ld6 system looks somewhat passive. White ' s possibilities are illustrated by positions 1 02- 1 06 . The system with the move . . . :!f5 requires further practical testing (-74, 77) . When studying the positions of the system 7 . . . 0-0 8 .c4 ct'l f6, one should take into consideration that they can also arise from the Queen 's Gambit Accepted (D20) . For instance, after the moves l .d4 d5 2 . c4 dc 3 . ct'l c 3 e5 4 .e3 ed 5 .ed ct'l f6 6 .:!c4 :!e7 7 . ct'l f3 0-0 8 .h3 ct'lbd7 9 .0-0 ct'l b6 1 O .:!b3 c6 1 1 .�el ct'l bd5 the position of line 7 8 arises . I n those cases where the opening was the Queen's Gambit Accepted, the numeration of moves has been altered. Some ideas, which are potentially conditioned by the pawn structure of the position, are illustrated by positions 1 07- 1 1 0 .

This interesting system became popular after the game Kasparov - Karpov, London wcm (6) 1 986. B lack immediately attacks the centre . After 9 .cd he employs Smyslov ' s idea: 9 . . . iLxf3 1 O .�xf3 �xd5 ( l O . . . tLJ xdS leads to the line 6 . . . iLe7-see Chapter 8 ) . Now and later, White can include the moves E1e 1 and iLe7, which also leads to positions covered in Chapter 8. However, the given position affords White more aggressive possibilities . 9.tLJc3 This pawn sacrifice is the most unpleasant continuation for B lack. He can decline the gift, switching after 9 . . . iLe7 to a position covered in Chapter 9 (-7 1 9/9 . . . tLJf6). 9 . . . iLxf3 ? ! 10.�xf3 tLJxd4 11 .�h3! A novelty, prepared by my opponent for this game, which turned out to be so strong that the whole variation went out of fashion. The white queen is very active on h3 and is aiming at the kingside.

At thi s moment Black fully realised the strength of his opponent ' s position : in re-

turn for the sacrificed pawn White has achieved an excellent attacking position, with two strong bishops, and has ideally placed his main pieces . B lack' s last move is practically forced because of the threat 1 6 .gxe7 �xe7 1 7 .LtJdS---t . I S . . . ge8 is met by 1 6 .ibS !± . Now White faces an important choice between winning back the sacrificed pawn after 1 6 .gxe7 hg ( l 6 . . . �xe7 l 7 . ct:J dS ct:J xdS 1 8 .ixe7 ct:J xe7 1 9 .b4±) 1 7 .gxb7, or adding fuel to the fire of the attack by 1 6 .ixh6. 16.ixh6! This is the correct assessment of the position ! After l 6 .gxe7 hg 1 7 .gxb7 Black has the important defensive move 1 7 . . . gb8, and after 1 8 .gxb8 ( 1 8 .gxa7 gxb2) lMfxb8 1 9 .b3 lMfeS White ' s advantage is not clear.

Chapter 7

I. 7.1. Overview

The laenisch System (6 . . . fle7-7 . . . CiJ c6) is the most popular in the Petroff Defence. Three chapters of this book are devoted to this system. White ' s main continuations are 8 .:ge 1 (-chapters 7-8) and 8 . c4 (chapter 9) . Other continuations do not promise him any advantage (-8 1 -82, position 1 1 2 . )

After 8 .:ge 1 Black can support the knight at e4 in two different ways : 8 . . . flf5 (the topic of the first part of thi s chapter) or 8 . . . ig4 (-part two and chapter 8) .

The 8 . . . flf5 system is reliable enough for Black. The line 9 .flb5 is not too dangerous (-84, position 1 1 3 ) . The continuation 9 .llJ bd2 ( -85) looks harmless, but B lack must be carefu l : even in this simplified position White retains a slight initiative on the e-file (-positions 1 1 4- 1 1 5 ) . The most unpleasant for Black is Karpov ' s continuation 9 .c4, when it i s much more difficult for him to fight for the centre (-86-88 , positions 1 1 6- 1 1 9) .

1 85

After 8 .ge i flg4 White faces a choice : whether to continue 9 .c3 or 9 .c4 (chapter 8 ) . The 9 .c3 variation is one of the sharpest and most complex lines in the Petroff Defence, and thus it is ideally suited for crucial battles. Before delving into the theoretical section which refers to this line, it might be useful to examine game 5 and positions 1 20-1 30 . They reflect some typical methods and strategic ideas of the variation. The main continuation 1 O .\Wb3 (after 10 . . f5) makes plans connected with queenside castling more dangerous for Black (-92-93). After 1 0 . . . 0-0 1 1 . CiJ bd2 Black has a choice between the reserved 1 1 . . . CiJ a5 (game 5 , -97) and the gambit-style l l . . . ct?h8 (-94-96) . Here he sacrifices the b7 -pawn, but gains time for preparing an attack on the kingside (-94-96). Although in this case the play is more concrete, it is important for Black to retain control of the key e5-square .

9.c3 f5 This offensive set-up is in the spirit of the position: B lack should oppose White ' s restrained play with an attempt to hold his ground in the centre (that i s , to support his strong central i sed knight) . The drawback to this move is that i t weakens the central e5-square, which can no longer be protected by a pawn, in contrast to the adjacent e4-square . 10.iWb3 An important par t of White ' s plan. Not only does he eliminate the pin on his knight and attack the b7-pawn, but he also exerts ad-

204

ditional pressure on the e4-knight in the event of Black opting for kingside castl ing (due to the pin on the d5 -pawn) . Often White begins with 1 O .ttJ bd2 instead. In my opinion, this i s less pre cise, since B lack gains additional oppor tunities associated with queens ide castling (-9 1 -92) . After the text move 1 O . . "W d6 or 1 0 . . .

According to Botvinnik, Black can equalise by 1 3" .m 6 1 4 .ixc61:l:xc6 I S,ctJeS Ei:a6. White, however, gets the better chances by continuing in thi s l ine 1 6: �c2 ihS 1 7 .f3 , capitalising o n the weakening o f the eSsquare . In order to protect this square , B lack uses a typical method: he exchanges his central knight, the pride of his position, for his presently passive opposite number, thereby opposing the future appearance of a white knight at eS (-positions 1 23 , 1 30) . 13 ... 4:Jxd2!? 14.CtJxd2 '&d6 l 4 . . . 4:J bS? ! fails to I S .h3 ! ihS 1 6 .ie2±, w hen White transfers his knight to eS . lS.4:Jb3?!

This chapter considers White ' s plan to undermine the centre by 9 .c4 . Typically, the ensuing positions differ only insignifi cantly from those of chapters 6 and 9. Theref ore, when studying these positions , i t is usef ul to become f amiliar with the ideas typical of them and to look through the corresponding positi ons and games at the end of this chapter. The position af ter 1 O.ctJc3 dc (-98-99) can also ari se f rom the Queen ' s Gambit A ccepted (- D20/2). Following the game K asparov-Timman, Amsterdam 1 994 (-99) apparently only a f ew players will be wi lling to maintain this line with Black. At the same time, the variations here with the pawn sacrif ice af ter 1 O .ctJc3 ixf 3 (- 1 00) are less dangerous f or Black than the corresponding lines of chapter 6 (-annotation to the I I th move of game 4 ) .

The continuation 1 0 .cd leaves Black a choice between 1 O . . . ctJ xd5 and l O ... ixf 3 . The f ormer leads to a typical structure with an isolated pawn. We consider some nuances of this structure in game 6 and in pos i t ions 1 3 3- 1 3 9. In general , Whi te should ai m to keep as many pieces on the board as possi ble and to increase the pressure on the k ings ide and in the centre . White ' s set-up with 1 2.h3 and 1 3.a3 largely corresponds to thi s concept. In this line White retains an opening initiative. Nowadays 1 O . . . ctJ xd5 has been practically displaced by the altern ative l O ... ixf 3 (- 1 06-1 09 , positi ons 14 0- 142 ). White has not managed to show any convincing ways of increasing the ini tiative. As a consequence, the entire system with I OJ::i: e I has become rare and has given way to the system with 8 .c4 , which is analysed in the next chapter.

A distinctive feature of thi s position with an isolated pawn is the location of the black knight on c6. On the one hand it exerts pressure on the centre, but on the other hand it does not allow Black to support his dS knight with a pawn.

White is aiming to attack. However, from now on he always has to reckon with the possibility of the black knight invading at c2 . 1 7 . a3 or 1 7 .�d2 was more cautious , but again White does not gain any advantage. For the time being the c2-square is indirectly protected ( 1 7 . . . liJc2?? I S . liJ xf6+) . Nevertheless , with a typical manoeuvre Black pushes the white queen back from fS . An analogous idea i s employed in the solution to position 1 33 .

An instructive mistake ! B lack does not take into account all his opponent ' s possibilit ies . The defending side should above all aim for the co-ordination of his forces, for the sake of which it i s often correct to return part of the extra material in order to gain time. This method was skilfully used by Lasker. Black should have immediately engaged his strongest piece in the defence either by 22 . . .

Chapter 9

1.9.1 . Overview

White's main weapon against the system with 6 . . . fie7 and 7 . . .tiJc6 is the immediate undermining of the centre by 8 .c4. It should be noted that some positions in thi s chapter differ only insignificantly from or even transpose into variations from chapters 6 and 8 . The continuation 8 . . . 0-0 does not have any independent significance. After 9 . cd '&xd5 1 O.t2k3 ct:Jxc3 1 1 . bc fig4 positions from the variation 8 . . . fig4 arise (- 1 1 2) . This line is advantageous for White (-position 1 44) . Among the rare continuations, Morphy ' s move 8 . . . fie6 deserves more attention ( I l l , position 1 43 ) .

The move 8 . . . ct:J f6 (- 1 1 3- 1 1 4) can lead to a position from the Queen's Gambit Accepted (D20) , which occurs when Black opts for the plan with ct:J c6 . For instance, the game Gelfand-Adams, Wijk aan Zee cm 1994, went l .d4 d5 2 .c4 dc 3 .e3 e5 4 .fixc4 ed 5 .ed ct:Jf6 6 .ct:Jf3 fie7 7 .0-0 0-0 8 .h3 I/Jc6 9 .ct:Jc3 and the position of variation 1 1 4 arose. Some typical ways of playing this line with White are considered in the solutions to positions 1 45- 1 48 . On the whole, White retains the initiative.

The most popular defensive system against 8 .c4 is the knight thrust 8 . . . ct:J b4 . After 9 .cd I/Jxd3 Black maintains the balance, a l -

though he has to play carefully (-position 1 49, game 7 ) . Instead, retaining the bishop poses more of a problem for Black. After 9 .fie2 0-0 1 O . ct:J c3 it is difficult for him to maintain h i s centre . White ' s plan in the event of 1 0 . . . fif5 (- 1 1 8) is well i l lustrated by the game Kamsky-Yusupov, Moscow 1 992 (-positions 1 52- 1 54) . The main continuation 1O . . . fie6 1eads after 1 1 .fie3 to the key pos i t ion of the v ariati on . Among B lack 's various possibilities, the line 1 1 . . .f5 (- 1 2 1 - 1 23 , positions 1 57- 1 60) and Arkhipov ' s move 1 1 . . . fif5 are reputed nowadays to be the most reliable . The latter seems to be an extravagant loss of tempo, but it is justified by the following consideration : in the l ine 1 1 . fie3 fif5 the black knight need not retreat after 1 2 . ct:J c3 ct:J xc3 1 3 .bc, but can invade the c2-square instead. I recommend to those players who have this line in their repertoire that they pay special attention to the game Topalov-Akopian, Linares 1 995 , in which the Bulgarian grandmaster treated the critical position of the variation (- 1 25 ) very SUbtly.

239

It goes without saying that the last word in these complicated variations has not yet been spoken. It should be mentioned here that the relatively new continuation 1 1 .ct:Je5 deserves further practical investigation. ( - 1 27 ) .

l .e4 e5 2.cuf3 cuf6 3.cuxeS d6 4.cuf3 cuxe4 5.d4 dS 6.id3 cu c6 7.0-0 ie7 8.c4 cu b4 The most popular system against 8 .c4 for Black. By attacking the bishop, he intends to weaken White ' s pressure in the centre . 9.cd

The alternative is 9 .ie2. The text move allows Black to exchange his knight for the bi shop, but White hopes to gain time in order to create threats along the open efile. 9 . . . 4J xd3 1 0.Wlxd3 WlxdS 1 l .Elel if 5 12.4Je5 If l 2 .4Jc3 cuxc3 1 3 .Wlxc3, B lack must sacrifice the c7-pawn by 1 3 . . . ie6 (-1 1 6, position 1 49).

12 .. . 0-O-0! ? 1 2 . . . f6 (- l I S ) , and 1 2 . . . g6 (-747) are B lack's other possibilities in this position. The text move creates the threat of 1 3 . . . WleS .

A typical advance, which the reader may remember from positions 1 1 8- 1 1 9 . It seems that White must gain a material advantage, but B lack's answer demonstrates that the opposite is so. Exploiting the weakened position of the white monarch, B lack begins a counterattack aimed at the most vulnerable point in the opponent' s campthe f2-pawn. 14 . . . ih4! Thi s idea occurs more often in the variations of chapter 7 (-game S ) .

A subtle move, after which the position of the black bishop at h4 becomes dangerous. 1 7 .Wxd5 ixd5 1 8 .c4 f6 1 9 .cd fe 20 .de E1xd5 creates less problems for Black . Here Black had spent a long time searching for a good defence. How can he l iberate the trapped bishop? One factor simplifies his task: the threat of 1 8 .Wf4 is il lusory in view of 1 8 . . . ih3 1 9 . E1e4 ixg5 . And yet a serious problem remains : how can he parry the threat of 1 8 .E1e4? The nervous 1 7 . . . f6? leads after 1 8 .gf Elhf8 ( 1 8 . . . E1 h e 8 1 9 . f7 ± ) 1 9 .Wxd5 ( l 9 . f7 ? El x f7 ! 20.WxdS ixf2+ 2 1 .<;t>fl ixe l + 22 .ciJ xf7 ixd5 2 3 . tU xd8? ixc 3 -+ ( Hertnec k ) ) 1 9 . . . ixd5 ( 1 9 . . . E1xd5 20.tUf3+-) 20.t7± to Black losing the exchange in view of the threats of ih6 and ia3 . By bringing the h8-rook into play, B lack maintains the balance by tactical means. 17 ... Elhe8! The point of this move becomes clear in the fol lowing l ine : after 1 8 . E1e4? ! if5 1 9 .E1xh4 Black has at his disposal the tactical blow 1 9 . . . E1xe5 ! If now 20.Wxd5 E1e 1 + 2 1 . \tlg2 E1xd5 22 .E1xh7 ie6 (Hertneck) he gains more than sufficient compensation for the pawn. 18.c4! White continues to fight for the initiative.

1 8 .id2 f6 1 9 .9f Wxf3 20 . tU xf3 � x f6 (Hertneck) would be weaker. 18 ... Wxd4 19.E1bl c6 1 9 . . . id5 ! ? was a good alternative in this position . Now 20.Wh3+ <;t>b8 [20 . . . �e6 != L12 1 .Wg2 c6 22.tUxc6 ixf2+ 23.\tlh I �d5 1 1 2 1 . ie3 [2 1 . tUd7+ <;t>a8 22. ie3 'lWxc4] i s not dangerous in view of the move 2 1 . . .

During the game I was worried about the continuation 20.cd Elxe5 2 1 .E1xeS �xe5 22.d6 ! (22.Wg4+ ? Wf5 23 .WxfS+ gf 24.:r'1b4 ixg5 25 .ixg5 E1g8+). Now 22 . . . E1xd6? is bad because of 2 3 .if4 WdS (23 . . . �f5 24.Wxb7+ <;t>d8 25 .ixd6 Wxf2+ 26.mh l cd 2 7 .Wc 6+- ( Hertn e c k ) ) 24 .Wh3+ �e6 25 .Wxh4 Wf5 26 .E1b3 E1e4 27.E1f3± . How· ever after 22 . . . c6 ! 23 .Wxf7 (23 .Wg4+ �f5 -+) 2 3 . . . E1d7 24 .Wg8+ E1d8 the game should end in a draw. White ' s best chance is 25 .d7+ <;t>c7 26 .E1xb7+ <;t>xb7 27 .�xd8 We I + 2 8 . \tl g2 W x f2 + 2 9 . \tl h3 � f3 + 3 0 . <;t> xh4 We4+ 3 1 . <;t> g3 Wd3+ 3 2 . lf1f4 Wf5+ when Black forces a draw by per· petual check (Hertneck).

2o.if4!? Again White finds the most unpleasant move for his opponent ! In the event of 20.tUxc6 Black would not reply 20 . . . �xf2+ 2 1 .Wxf2 ixf2+ 22 .<;t>xf2 bc 23 .if4 �d3 (23 . . . E1d4 (Hertneck) 24.ie5�) 24.�b8+ <;t>d7 25 .E1b7+ <;t>d8 with the idea of E1d7. when although he is a pawn up, it is White who has winning chances. The correct reo

ply is 20 . . . 'Wg4+ ! 2 1 .'Wxg4 ixg4 22/i'Je7+ (22.ctJxa7+ mbS) 22 . . J::J:xe7 23 .:§:xe7 :§:d l + 24.cttg2 ixg5 with equal chances . 20 . . :�c5 2o . . . if5 is weak in view of 2 1 .:§:bd I with the idea of ctJxf7±. Black seems to have managed to parry all the threats, but it turns out that his opponent's attacking resources are far from exhausted . A tactical skirmish now commences, in which the players exchange blows .

Part II

Chapter 1

11.1 .1 . Overview

Thi s small chapter deals with 3 . . . d5 and other deviations from the main l ines of the 3 . . . exd4 system, which is analysed in Chapter 2. The continuation 3 . . . d5 is not dangerous for White. He can transpose into the 3 . . . l2l xe4 system (-Chapters 3-7) b y playing 4 .l2lxe5 l2l xe4 5 .�d3 . Other continuations : 4 .�g5 (-2) and 4 .ed (- 1 -2) also give White promis ing play. Those who dis l ike long theoretical l ines might prefer Tal ' s move 5 .�b5 (-3-4). However, after this B lack can switch to the Ruy Lopez (ECO C/65 ( 1 )) by playing 5 . . . l2l c6 ! ? and l ater to the system C84 (ECO), which are not considered in thi s book.

272

Thi s chapter i s important for Black if he wishes to play the system 3 . . . ed. He has to take into account the fact that after 4.�c4 White can switch to the Urusov Attack in the B i shop's Opening (ECO C24/6- 1 1 ) , We offer two recommendations (- 1 5 ) which may allow the successful handl ing of thi s system without profound theoret i cal knowledge . Another deviation - Steinitz ' s move 5 .'tWe2 - is less dangerous for B lack. He can choose between the sharp 5 . . . �b4 ( -5 ) and the more cautious 5 . . . l2l c5 (-6-7 ) , After 5 .�b5 the best choice for B lack is to switch to the Ruy Lopez.

Chapter 2

11.2.1 . Overview

This chapter turns to the analysis of 3 . . . ed, 'a solid and reliable system' . Geller and Smyslov 'played a number of games that way' (Viktor Kortchnoi ' s remark from the Soviet film Grandmaster, in which he was acting as a coach) . The 3 . . . ed system is a suitable choice for a positional player who does not mind defending a slightly inferior ending (-game 1 ) . It is not by chance that this system has often been played by players such as Smyslov, Kholmov and Trifunovic. For those players who intend to play this system with B lack, we recommend studying the previous chapter (-3-7) thoroughly. Since 7 .figS is not dangerous for B lack (- 8-9), the main choice i s between 7 .ciJ c3 and 7 .fid3 . Very often these continuations

283

transpose . For this reason, it i s recommended that both moves be studied. 7 .fid3 a l lows White to avo id the l ine 7 JiJ c 3 ct:l fS ! ? , which was tested i n the KasparovKarpov match, New York! Lyon 1 990 (-1 8- 1 9) . After 7 . ct:l c3 White can postpone the development of his light-square bishop (- 1 4) . B lack can choose a universal defensive system 7 . . . g6 (- 1 4- 1 7 ; 24-27) . In my opinion, White ' s most promising set-up is the development of his bishops at d3 and e3 and queenside castling (-27 ) . Very often the crucial factor for an adequate assessment of the critical positions in this l ine i s B lack' s ability to simplify the game. Various ways of reaching this goal are analysed in game 1 and in positions 1 2 , 1 3 , 1 9 and 20.

A very logical continuation: the darksquare bishop will be ideally placed on the main diagonal . An interesting alternative is 8 . . . C2lfS ( 8 . . . i.e6 - 10; 8 . . . i.fS - 1 1 - 1 3), introduced by Karpov, where Black tries to exploit the vulnerable position of the white queen . Regarding this line - 1 8- 19 . Now White faces a problem: where to develop his bishops ? The most active, and, in my opinion, the best set-up - i.e 3 and �d3 - has only one drawback: White has to reckon with the capture on c 3 . The text move solves this problem, but impedes White's further play on the d-file (in view of the impossibility of realising the manoeuvre i.cs -Pos . 17 and 2 1) . 9.�d2 Wfe7+ A good continuation . 9 . . . i.g7 is also possible -IS and Pos . 1 2 . 1O.ie2 Threatening 1 1 .l2ldS .

The immediate l 2 .E1he 1 also deserves serious consideration . After l 2 . . . Wff 6? (the standard relieving manoeuvre) White has the strong response l 2 .l2lgS! (VujicNedelkovic, corr . 1 97 8) . Here this typical thrust is carried out in a more favourable situation for White than in line 27 . A better continuation is 12 . . . 0-0 (Forintos, Haag), with double-edged play. The text move creates the threat of 1 3 .hS, with an initiative on the kingside . However, at first sight the stereotyped response 1 2 . . . h6 seems clearly to b e in Black's favour, since White is deprived of the effective resource l2lgS . However, a strong player such as Geller does not make aimless moves: the essence of White's plan, aimed at exploiting the micro-weakening of the g6 square, will become evident after three moves . 12 ... h6 13.E1hel 0-0-0 1 3 . . . 0-0 is risky in view of l4.i.d 3±, and

Black cannot simplify the game by 1 4 . . . Wff6, because after the exchange of queens he loses the h6-pawn . 1 3 . . . Wff 6 (an analogous idea is used in Pos . 1 2) might lead to

At first sight Black appears to have a diffi-

Chapter 3

11.3.1. Overview

This chapter consists of two parts. The first sum marises various marginal possibilities after 3 ... ct'lxe4 and 4.�d3 (28-35). The second deals with Black's less popular reactions to 5.ct'lxe5: 5 ... ct'lc 6 and 5 ... �e7 . Despite the good results of GM Romanishin in the system 4.�d3 d 5 5.de, it is not difficult for Black to equalise (-32-3 5) . Players who like to avoid theoretical battles might choose the interesting move 4 ... ct'lc 6, introduced by Murey (-30-31, position 23). However, recent games with this line show that after 5.de Black has to solve

312

some difficult problems. (-3 1). However, this syste m still needs further practical testing, which should give a final diagnosis. The positions arising after 5 ... ct'lc 6 are very si milar to those fro m Chapter 6 (-70-78). A mong recent examples, the game Ivanchuk - Yusupov, Novgorod 1995 (-224). deserves serious attention. It illustrates well the proble ms that Black faces in this - at

first sight - harmless position. The continuation 5 ... �e 7 is passive and allows White to seize the initiative with active central play.

Chapter 4

11.4.1. Overview

This and the nex t chapter ana lyse the 5 . . . ctJd7 system, which i s currently the most popul ar for B lack. The first section of chapter 4 (44-52) summarises White ' s alternatives on move 6. The second section (55-63) deal s with B lack 's dev iations from the main l ine (which is covered in Chapter 5 ) . Modern practice has shown that after 6 .Vffe2 (th is main alternative is analysed in l ines 48-52 , positions 30-3 3 and game 2) , B lack gains sufficient compensation for the pawn . In my opinion, if White is trying for an opening advantage, he has to opt for 6 .ctJ xd7 and fol low the main l ine . There are many i nteresting alternatives for B l ack. The cautious continuation 7 . . . 1e7 gives him a reasonable position (-54-55 , positions 36-40), although precise play wi l l enable White to keep the init iative .

332

My attempts to rehabi l itate the pawn sacri fice in the 7 . . . 1d6 l i ne have not been very successfu l ( -56-58 , positions 4 1 -42). Although B lack definitely has active possib i l i t ies, I have been unable to obtain ful l compensation for the pawn (-58 ) . Perhaps, i t would be helpfu l to analyse the ending Sveshnikov - Zaitsev (-343 ) .

Those who prefer gambit play might try the dubious 7 . . . Vfff6 (-59-60, positions 43-44) .

The recently popular l ine 7 . . . g 6 was put i nto quest ion after the games Anand -Huebner (position 48) , Rozental is - Ivanchuk, Debrecen European tch 1 992 ( -388) and J . Polgar - Skembri s , Moscow 01 . 1994 (-62 ) . B lack must search for new defensive methods .

An interesting continuation aimed at prevent ing White ' s manoeuvre V9aS . Now

1 2 .a3 f6 1 3 .V9g3 �d6+, or 1 2 .a4 a6 is harmless for B lack. Of principal significance is 1 2 .c3 f6 1 3 .V9g3 �e7 ( l 3 . . . �d6 is met by 1 4 .�f4 , since the d4-pawn is protected) 1 4 . ctJ d2 hS�. After 1 2 .c3 B lack can also play 1 1 . . . �d6, with good play, since the

knight cannot be developed at c3 and the

queen cannot return using the e I -aS diagonal to part ic ipate in the defence of the

kingside . However, the less subtle 1 1 . . . id6 1 2 .V9a5 �dS also deserves attention. 12 .ctJc3? ! f6 13.V9g3? !

\ 3 .'iWf4 was better. 13 . . . �xe3 l4.be ( -3 1 3 ) . As a result of White ' s dubious twelfth move, his pawn chain has lost its flexibility, and his extra pawn on the queenside is of no importance. Moreover, his darksquare bishop is restricted by its own pawns. The activity of the bishops i s normally the crucial factor in evaluating posit ions with opposite-colour bishops . 14 . . . h5! It goes without saying that B lack i s trying to open the kingside. 15.h4 g5 l 6.f3 1 6 .hg? fai l s to l 6 . . . h4 1 7 .'iWh2 h3 1 8 .g3 id5=t=, with a strong attack (the threat i s 19 . . . �g2, blocking in the 'iWh2) . 16 . .

At first sight it seems that White has managed to consolidate his position with careful defence. It is unclear how B lack can in tens ify the pressure on the k ings ide . However, White ' s last move allows B lack to switch to offensive operations in the centre . With a subtle manoeuvre Larsen further restricts the range of the white bishop and, even more importantly, reduces the mobility of the f2-rook !

l7 . . . 'iWe6 l 8.�d2 g4 1 9.f4 �e4! Now the difference in the activity of the pieces is appreciable. Without making a single obvious mistake, White has found h imself in a strateg ica l ly lost pos i t ion . B lack seizes the only open fi le, which allows his rooks to attack the white king from the e2-square . Karpov clearly sees that i t i s impossible to defend the weak pawns on the queens ide and at the same t ime to fight against the rook invasion of the second rank. Reali sing that passive defence wi l l be hopeless , he decides, at the cost of a pawn, to activate his bishop. However, this pawn sacrifice merely enables him to delay the end.

Chapter 5

11.5. 1 . Overview

The Makarychev Variation can rightfully be called the ' tabia' of the 5 " .liJd7 system. The game is double-edged here . In many posi tions B lack must watch out for the thematic c5-c6 (- see the examples for the solution) . At the same time the vulnerable point of White ' s formation is the pawn at d4. B lack's typical methods include the exchange sacrifice on e2 (analogous to position 46), and then the advance . . . g5-g4-g3 , leaving the e4-knight under attack (- see the examples for the solution . ) A s always, the l ines adopted by the world champion Garry Kasparov deserve special attention. His beautiful win over Ivanchuk should be studied thoroughly (-positions 49-50) . Unfortunately, there i s very limited practical material about 1 O .�e3 (-64) . The most popular continuations are 1 0 . f3 (-65-68) and 1 0 .liJc3 (69-75) , which can both lead to the same position that occurs after I 0 .liJc3 �g7 1 1 .liJe2 (70) . Hence, it i s useful to study them together (-positions 53-58) . Zoltan Almasi, playing White, suc-

cessful ly handles the complicated position arising after 1 O. f3 liJ f6 1 1 .�e3 g4 1 2 .g3 �h5 1 3 . f4 . Thi s pawn structure can emerge in different l ines of the 1 0 . f3 system and studying it therefore has considerable practical value . In my opinion, B lack has sufficient counterplay here .

363

Anand-Ivanchuk, Linares , 1 993 (-position 60) saw a new and original version of the popu l ar exchange sacri fice in the l i ne 1 0 .liJc3 �g7 1 1 .g3 (-74-75 , game 3 ) . So far B lack has not found an effective antidote to the Indian grandmaster ' s idea and has been unable to overcome these difficulties. The Makarychev variation i s a good weapon for B lack, but for playing thi s system, solid preparation before the game is essential . Those who want to include the Makarychev Variation in their repertoire should study new games with great care, s ince thi s l ine i s constantly developing and the problems which ari se require very precise play.

This manoeuvre, which is standard for the S . . . lLld7 system (-Pos . 29 and 42), leads to a double-edged position with the kings on opposite wings. B lack tries to exploit the absence of the white knight from the

kingside to develop some initiative there . 8.c4 In accordance with the basic principles of

chess strategy, White meets Black's flank attack with central play. 8 • . • 0-0-0 Unfortunate ly for B l ack , the tempting 8 . . . �d6 i s met by 9.g3 Wl'h3 (9 . . . lLl xg3 fai ls to I O. fg �xg3 I I .WI'e2+) I O .cS or I O .�c2 (-370), with advantage to White. 9.cS gS The main alternative to the text is 9 . . . g6 (-6 1 -63) , which leaves the gS-square free for piece manoeuvres . However, after this move B lack does not control the f4-square and i s deprived of many active possibi l i t ies (e . g . , the advance . . . gS-g4 or transferring the rook to the attack via the 6th rank) . 10.lLlc3 The alternatives are I 0 .�e3 (-64) and 1 0 .f3

Geller improves White 's play, by placing his queen at a4 and keeping control of the important squares d l and d4. Black is now depr ived of active counterplay and aims for simplification . White has created one obvious threat (to win the a 7-pawn) and two veiled 'potential ' threats : the advance b4-bS and

the bishop sacrifice on c6. How can Black defend his position? The choice of move depends on the assessment of which threat is more dangerous . B lack decided to take measures against the bi shop sacrifice and chose 1 9 . . . � b8 . However, as the rest of the game showed, the black king was very vulnerable at b8. Better was 1 9 . . . a6.

Despite the equal material, B lack's position is very difficult because of the vulnerable position of his king. White ' s attacking chances are especially enhanced by the opposite-colour bishops : the g2-bishop i s exerting tremendous pressure on the long d iagonal , whereas B lack ' s dark- square bishop cannot help his king. 24 ... cb?

Chapter 6

11.6. 1 . Overview

This chapter and the next are devoted to the 5 . . . �d6 system, or symmetrical variation . In chapter 6 the various deviations on moves 6- 1 0 from the tabia of the symmetrical variation are covered . The best choice for White i s to go for the tabia. However, i t requires painstaking work involving the studying of long theoretical l ines. If he does not have particularly strong ambitions in the opening stage, he can play for a knight exchange at e4 by ctJ d2 (-76

and 78-79, positions 6 1 -66), or ctJc3 (-465 , 80-83 , positions 67-69) . S ince B lack i s currently experiencing a cri s i s i n thi s tabia, he may consider choosing the variation 7 . . . ctJc6 ( -85 , position 70) . However, my personal experience has been unsuccessfu l : losses in games against Timman (Linares cm(8) 1 992 -game 4) and Ivanchuk (Horgen 1 995) , along with only one draw, but thi s against Kasparov (Horgen 1 995) .

The main di lemma when playing symmetrical positions is deciding when to deviate from the move repetition. The early development of the queen's knight leaves open an additional possibil ity, in contrast to 6 . . . 0-0 7 .c4 ctJc6, but in my opinion it does not allow Black to achieve equality. 7.ctJxe6 The simplest reaction to 7 .c4 is 7 . . . ctJxd4 8.�xe4 �xe5 9 .cd 0-0, since 1 O.�xh7+? <j;>xh7 I I :&h5+ <j;>g8 1 2 .'&xe5 is bad in view of 1 2 . . . ctJc2 (-476) . 7 . f4 is possible (with change of colours it is analogous to 7 . . .f5 in variation 83) . The text move damages Black's pawn structure . 7 ... be 8.e4 Other moves are weaker: 8.1:'l:e l �xh2+=; 8.'&e2 a-a ! 9 .�xe4 1l{ih4 ! � or 8 .ctJd2 ctJxd2 9.�xd2 0-0 1 O.c4 dc= (-477) . It is important for White to drive the bi shop back from its active post at d6.

8 ... 0-0 If 8 . . .'&f6, then 9 .�xe4 de 1 0.lLlc3 and it becomes hard for B lack to cope with all his pawn weaknesses. In particular, after 10 . . . 0-0, I l .c5 �e7 1 2 .lLlxe4± is unpleasant. The prematurely active 8 . . . �h4 does not promise much because of 9 .g3 �h3 (9 . . . lLlxg3 ? ? 1 0 . fg �xg3 1 1 . �e2+ +- ; 9 . . . �f6 1 O.�xe4 ! de I l .lLlc3 �f5 1 2 .f3 ! -479 . ) l O .c5 ! �g4 ( l O . . . �e7 1 1 .�f4± Xc7) 1 1 .�e2 ! �xe2 1 2 .�xe2 �e7 1 3 .f3 lLlf6 14.�f4± -78. It might be interesting to compare thi s variation with (498/8 . . . c5/B2) , where the same position with reversed colours occurs and the extra tempo allows White to start an attack. 9.c5! 9.lLlc3 is inconsistent, since after 9 . . . lLlxc3 IO.bc dc Black maintains his bishop on its ideal post. After the text move the defects of the pawn structure become more eivdent, since the bishop does not have any squares on the b8-h2 diagonal . 9 ... �e7 10.lLlc3

A powerful continuation. White increases his pressure in the centre . The exchange at c3 is unattractive for Black, since he will be deprived of counterplay against the d4-pawn. If l O.lLld2, then 1 O . . . �f6 and 1 0 . . .

lLlg5 ! ? are possible ; 1 O .f3 is less precise because of 1 0 . . . lLlg5 I l .lLlc3 E1e8 ! which prevents �e3 and obtains a good game . (Kasparov - Yusupov, Horgen 1 995 -529/ 1 0.f3/C) . 10 ... f5 The drawback of this move is evident: the important e5 square is weakened. Instead of 1 0 .. .f5 two other continuations deserve attention: 1 0 . . . �f5 1 1 .�c2 �g6 1 2 .lLle2 lLlg5 and 1 O . . . �f6 . In this line Ivanchuk demonstrated a strong idea against me in the same tournament: 1 1 .�c2 ! The strength of this move can best be seen in the variation I l .lLlxe4 de 1 2 .�xe4 �a6, when Black solves his problems. Now after 1 1 . . . �xd4 1 2 .lLlxe4 de 1 3 .�xe4 �a6 White has the unpleasant 1 4 .E1d l (-530/ 1 0 . . . �f61D) . 1l.lLle2 After 1 1 .f3 White would have to reckon with 1 1 . . . lLlxc3 1 2 .bc f4 ! , when B lack seizes space on the kingside. 1l ... �f6

I I . . . a5 ! ?, aiming for the strategically favourable exchange of light-square bishops, doesn't help much because of 1 2 .�a4 �a6 1 3 .lLlf4 �d7 1 4 .�xa6 E1xa6, and White occupies the key eS-square after 1 5 . lLld3 �f6 1 6 .f3 lLlg5 1 7 .�xg5 �xg5 1 8 .lLle5 . 12.�a4!± This is the ideal post for the queen: from here it offers good protection to the d4-pawn and simultaneously exerts pressure on Black's weak a7- and c6-pawns. 12 ... �d7 1 2 . . . �d7 , preserving the possibil ity of ex-changing the light-square bishops by a7-a5 and �a6, deserves consideration.

Timman's play in this game is exemplary. Not only does White arrange his forces in the optimal way, but at the same time he effectively controls his opponent's counterplay.

Chapter 7

11.7.1. Overview

The tabia of the symmetrical variation is one of the most elaborate lines in the Petroff Defence. For a long time the variation with 15. ct'lc3 (-93) was considered obligatory for both sides. However, some time ago the new idea I S .�f 4 (as well as the same continuation on the 14th move -91) became a powerful stimulus for the development of the system. Timman landed the strongest blow against Black's defensive strategy in this line in the 6th game of his Candidates Match in Linares in 1992 (-92, game 5). His opponent - and victim -was once again the author. Black's real alternatives are the continuation 19 ... 1::i:xd2 (-99), which oc-

cUfred in Kasparov-Anand, Linares 1991, and I S . .. f6 (- positions 72-75, 94), which withstood the test in Kasparov-Timman, Paris Immopar 1991. Despite the positive results of these games and the fact that these lines have so far not been refuted, I would not suggest that anybody should repeat them against the World champion Garry Kasparov. To my mind, the symmetrical variation itself and especially this tabia are in a critical state. It is not by chance that the 5 ... ct'ld7 system has currently become much more popular than the symmetrical variation.

By attacking the eS-pawn, Black tries to gain time for development and thereby justify his exchange of bishop for knight. The play is now very concrete and the assessment of the position requires the perception of subtle nuances. For a long time this line was regarded as holding no prospects for White. However, new possibilities recently discovered, which improve White's play, have substantially changed the assessment of this very important defensive line for Black. The tabia of the symmetrical variation no longer occurs frequently. 9.ed Wxd5 Regarding 9.if4 and 9.f4 -86 and 87. White tries to exploit the vulnerable position of the knight at e4. 10.We2! W.Wf3 is weaker in view of W . .. ifS -Pos. 72. 10 ... ctJb4 W ... ifS fails to 11.ctJc3 t.I± -S49.

1l.ixe4 tDxc2 12.ixdS

Black wins the exchange, but his knight is in danger. The assessment of the position essentially depends on Black's ability either to save his knight (often returning the exchange), or to obtain sufficient compensation for the sacrificed piece (i.e., to achieve the ending l'l:+� or l'l:+�+� vs. two minor pieces). It is important to gain control of the c2-square, through which the black knight can escape. 12 ... ifS

The immediate 12 ... tDxal allows White a clear advantage after 13.ie4 l'l:e8 14.tDc3 l'l:xe5 15.id2 l'l:xe4 16.tDxe4 tDc2 17.l'l:c1 if5 18.f3;1; -89. 13.g4!

Sacrificing a pawn, White gains control of the c2-square. Now 13 ... ig6 is bad in view of 14.f4 c6 (l4 ... id3 15.l'l:dl ia6 16.e6±-553.) 15.ic4 b5 16.f5± -90. 13 ... ixg4 14.ie4

421

In Timman's view, 15 . . . f6 was stronger (-94 and Pos. 73-75). The text move is aimed at drawing the bishop away from c2 and gaining time to organise counterplay. However, Black attains his goal at the expense of weakening the position of his king and allowing White a dangerous passed pawn in the centre. 16.idS+

16.ixb7 is met by 16 ... tDc2!=, and Black attains his goal (-95). 16 ... c;t>h8 17.l'l:c1!

Black is planning to double rooks on the d-file. In the second game of this match I managed to equalise after 21. E!xal g5! (Pos. 77 and 100). But Timman had prepared an important improvement. White does not try to achieve a material advantage, but instead he sacrifices a pawn, intending to achieve a more harmonious coordination of his pieces and to establish a secure position for his knight. 21.if1! E!d4 22.ie3 E!dS 23.E!xal In my home preparation I underestimated this move. I was mainly concerned with White's attempts to save his e5-pawn, but after 23.f4 E!adS 24.e6 E!Sd6! or 23.e6 E!d6 24.ic4 (24.e7 E!d7) 24 ... b5 Black has good play. 23 ...

Normally, an exchange of rooks would be in Black's favour, but after 25 ... E!d I +

Afterword

New ideas in the Petroff Defence

The theory of the Petroff Defence is not static and new ideas arise constantly. The Murey System was recently developed further (- games 1 -3 ): White looks for deficiencies in Black's original setup along two main l ines: 5 .d5 (game 2) and 5 . c!tJ xe5 (game 3). Timman became one of the main proponents of this system, but even he was not entirely able to solve certain complex defence problems . Black's general cris is in system 3 .d4 (C43) deepened on account of White's important findings in the quiet l ine 5 . . . c!tJd7 6 .c!tJxd7 ixd7 7 .0-0 ie7 (game 4) . However, the author managed to rehabi l i tate the l ine 5 . . . c!tJd7 6 . c!tJ xd7 ixd7 7 .0-0 id6 (game 5 ) . It should be noted that precisely this line was chosen by Karpov against Kamsky during their World Championship Match in

1 994. Nowadays it is the most promising line in this system. Black's positions seem reliable in the system 3 .c!tJxe5 (C42) . Thus, in the l ine 8 .c4 a new 'tabia' arises after 8 . . . c!tJ f6 (game 6) . This l ine leads to very interesting positions with manifold possibil ities for both sides . Those who prefer the more aggress ive 8 . . . c!tJ b4 will have to reckon with a new system: 1 1 .c!tJe5 (game 7) . Interest in the Petroff Defence is , general ly speaking, quite stable. It i s worth noting, however, that this old opening has recently won some new adherents: even as convinced a "Sicil ian" as Vladimir Kramnik has recently included it in his repertoire !
