Preface "It is not easy to play against this line, partly because many people do not consider it a strong move and un derestimate it"- Judit Polgar Since my original book on this sub ject in 198 1 , the c3 Sicilian has gone through a remarkable transforma tion. Of course grandmasters like Sveshnikov and Rozentalis have al ways played it, and no doubt they always will, but this little second move has also gained a niche in the repertoires of GMs such as Kramnik, Adams, Nunn and J.Polgar, not to mention Anatoly Karpov. Its unex pected blossoming has probably been assisted by the advent of data bases - which encourage top players to vary their openings - and faster time limits, which make surprises in the opening harder to deal with. As the title suggests, this book aims to provide an in-depth refer ence work. I felt this was needed, as there has been an explosion of games played, and there is simply no mod ern work of any substance on the variation. Which variations should be classified as main lines were not even clear to me when I started my research this time, as the majority of variations have changed beyond recognition since my first book. I apologise in advance if some of the material is quite heavy. However as you work your way through a line,

console himself with the pleasant thought that your efforts will cer tainly be rewarded soon over the board. Unlike many specialised vari ations, the chances of actually get ting the c3 Sicilian are extremely high because it requires such mini mal co-operation from the opponent. If Black plays the Sicilian, you get it!

The main . . . e5 break (4 ...lLlc6 5 ltlf3 cxd4 6 cxd4 e5) received atten tion from Joe Gallagher when he made it one of his recommendations for Black in his 1 994 book Beating the Anti-Sicilians. Gallagher con tends that the main variation 7 lLlc3 ..t b4 8 ..t d2 ..t xc3 9 ..txc3 e4 does not deserve its reputation as a poor line for Black, and this view is rea sonable. In the principal continu ation, 10 lLle5 lLlxe5 1 1 dxe5 lLle7, White has a wide choice, but against exact defence the route to an advan tage remains problematic. Yet giving up the bishop pair so early simply does not seem to appeal to top play ers; the ...e5 defences continue to be used infrequently by Black at grand master level.

The most widely played of the ...e5 breaks. It is unwise for White to continue 7 dxe5? !

This move-order is usually used if Black is intending to play some line with ... e5 (for example 5 cxd4lbc6 6 lbf3 e5) as already examined in the first chapter. However, if this is not the intention, then 4 . . . cxd4 must be considered a gratuitously premature exchange of pawns by Black. He does not necessarily gain a disadvan tage by force, but the move definitely gives White more possibilities about where to put his pieces. The point is that 4 ...cxd4 5 cxd4 has freed the c3-square for White's knight very early. It has been ac cepted wisdom that then Black will have serious tactical problems if he tries any ...i.g4 systems: on 5 ...lbc6 6lbf3 i.g4, the energetic 7 lbc3 has long been considered to be a very

strong riposte. However, as can be seen from Game 4, things can no longer be considered so straightfor ward. But even if this previously dis credited line does prove playable for Black, the significance is not enor mous, as with the safe alternative 7 i.e2 White brings the game back into the standard lines covered in Chapter 5. The one case where this move-order could conceivably be to Black's advantage is in avoiding somelba3 lines where White usually meets ...cxd4 by lbb5 , followed by capturing on d4 with the knight. Food for thought. The most prudent follow-up for Black (after 5 cxd4 lbc6 6 lbf3) is 6 . . . e6. With the ... i.g4 pin is no longer a worry, White can then seek more active squares for his king's bishop than the e2-square. The bishop can, of course, take up its tra ditional post on d3, contentedly con trolling the bl -h7 diagonal, but White can also be more ambitious. In the variation 7 lbc3 'ifd8, the bishop can also develop to the c4square- giving an excellent IQP po sition by analogy with some other openings. It should be noted that the posi tion after 4 . . . cxd4 can also arise via a Morra Gambit Declined move or der: 1 e4 c5 2 d4 cxd4 3 c3 d5 4 exd5 'ii'xd5 .

Now 6 �3 1i'xd4 7 .td2 or 7 .te3 would actually be a transposi tion, with colours reversed, to the speculative Hennig-Schara Gambit ( 1 d4 d5 2 c4 e6 3 �3 c5 4 cxd5 cxd4 5 'ii'xd4 li:)c6 6 'ii'd 1 exd5 7 'ii'x d5). I'm sure readers want more with White from the c3 Sicilian than this theoretically challenged pawn sacrifice; however if you want more information look under D32 in vol ume D of ECO, the Encyclopaedia of Chess Openings. 6li:)f3 .tg4 The most prudent move is 6 . .. e6, when transposition to later chapters is highly likely if White chooses to develop his bishop to d3 (or e2).

(there is noth ing wrong with 8 .td3, but this is stronger) 8 ...li:)f6 9 0-0 .te7. Here we

have a position which can arise from a myriad of openings (Queen's Gam bit Semi-Tarrasch, Queen's Gambit Accepted, Caro-Kann. . . ), with one major difference being that, com pared to some of these transposi tions, here White is already a tempo ahead !

Even in the second (1987) edition of Sicilian 2 c3 there were scarcely any examples of players using this astute move-order. Since then, how ever, it has become highly popular. I recommended it at the time for at tempting to cancel out White's entire .i.d3 systems (6 .i.d3 .i.g4 !), since Black's idea is that White must de velop his bishop at the less active e2square. After 6 .i.e2 Black then plays 6 . . . e6, reaching the less critical lines examined in Chapter 6. But White has not been idle. In this section we examine interesting alternatives that aim to exploit Black's move-order. A principled challenge

is 6 dxcS ! ? (Game 5). Some very strong grandmasters indeed (Ljubo jevic, Judit Polgar...) have been com prehensively wiped out as Black by this deceptively dangerous pawn capture. However, with accurate play White has only a minimal plus. Therefore 6 .te3 has also emerged as a sound response, as it commonly brings Black back into standard lines examined in later chapters. After 6 . . . cxd4 7 cxd4 e6 8 ltJc3 1Wd6, for example, White can continue 9 a3 ! .te7 10 .i.d3 and the king's bishop has, after all, occupied its rightful di agonal. True, White has committed his other bishop quite early to the e3square, but this move-order has re sulted in this system becoming the modem main line of the 2...d5 defence (see Chapter 10). If Black should try to cut across this plan with the esoteric 6. . .ltJg4!? remains unclear. The third try for White, 6 lDa3, just doesn't work in this particular position- a quick ... .tg4 and ... 0-0-0 by Black gives easy equality. Game S Blatny - Bonsch

The attraction of this sound and increasingly popular defence is ob vious. The queen's bishop immedi ately takes up an active post, and Black's pieces will develop very naturally: . . .e6, ...lLlc6, . . ..te7 and ... 0-0. A key point about the circumspect move-order 4 . . . lLlf6 (as opposed to the less accurate 4 . . . lLlc6, covered in the next chapter) is that Black can usually delay swapping on d4. To pre cipitate this pawn exchange White is more or less forced into .te3 at some stage in the main line; not a bad de veloping move, of course, but also not as active a square for the bishop as g5, for instance. As soon as the white bishop comes to e3 (threatening dxc5)

Black must exchange pawns on d4, whereupon a subsequent lLlc3 for White gains the traditional tempo against the black queen on d5 . The most notable current adherent of 5 ... .tg4 is Garry Kasparov. In deed he lost one of the most famous games of 1 996 using it - to Deep Blue, in the first game of their man v computer match in Philadelphia. De spite this, the main variations are looking extremely solid for Black, and can be recommended as an ex cellent choice, especially if Black is content with a draw. There are, naturally, slight down sides to the 5 . . . .tg4 defence. On g4 the bishop can be something of a tar get; h3 invariably gains time for White, and just occasionally a later g4 follows. Black may also notice the absence of the bishop from his queenside when White plays moves like 'ili'b3, attacking the pawn on b7 . Also, in developing a queenside piece like this, Black remains several tempi away from kingside castling. Whilst attempts to capitalise on this lagging development with 6 'ii'a4+ have largely backfired on White, a startling new idea is 6 lLlbd2!?. See Michael Adams's fantastic demoli tion of Hubner (Game 9) as an exam ple of just how effective the c3 Sicilian can be, even at the highest levels.

This move-order is inaccurate for Black. After 5 lbf3 i.g4 6 i.e2 it can be risky for him not to exchange pawns with 6. . .cxd4 - on the alterna tive 6 ... e6 White has the option of 7 h3 i.h5 8 c4! followed by advancing his d-pawn to d5. Whilst exchanging pawns on d4 early is not necessarily catastrophic for Black, it does mean that White has many more options than in the related lines examined in Chapter 4 (with the cautious 4 ...lbf6 5 lLif3 i.g4 move-order). The most significant variation (after 5 lbf3 i.g4 6 i.e2) runs 6 ...cxd4 7 cxd4 e6 8 lbc3 'ii'a5 ! ? (Game 1 3). The assess ment of the endgame that can arise after the continuation 9 0-0 lLif6 10 h3 i.h5 1 1 i.e3 i.e7 1 2 'ii'b3 'ii'b4 is important, but it seems that with

A de finitive evaluation of the ending aris ing after 5 ...'ii'xd1+ 6 �xd1 is rather difficult, as Sveshnikov is the only top grandmaster who has regularly played the position.

c5 d5 'ii'xd5 e6 (D)

Here we examine lines where Black plays an early ... e6, and gener ally . . . lLlc6 also, and White avoids the main-line variations (with .i.d3) of later chapters. There are several reasons why developing the queen's knight so quickly with ...lLlc6 can cause some small extra worries for Black. Also bear in mind that as the position can be reached via the move-order 1 e4 c5 2 lLlf3 lLlc6 3 c3 d5 4 cxd5 'ii'xd5 5 d4, these positions cannot necessarily be avoided if Black wishes to always play the ...d5 lines of the c3 Sicilian. In Game 14 we see one of those niggling problems for Black. After 6 lLla3 !?, 6 ...cxd4? ! 7 lLlb5 'ffd 8? is powerfully answered by 8 .i.f4 ! ±. In contrast, had Black played 5 ...lLlf6

instead of 5 . . . lLlc6 (Chapter 7), he would have the defence 8 ...lLld5 against this plan. There are also sev eral variations where Black would like to have the useful option of ...lLla6 or ...lLlbd7, as can be seen in the follow ing chapter which deals with lines where ...llJc6 is delayed. Therefore 6 lLla3, against this particular move order, is a promising continuation. White has real chances of an endgame edge in the main lines that arise after 6 ... lLlf6 7 lLlb5 'ii'd8 8 dxc5. In Games 15, 16 and 17 we exam ine (after 5 lLlf3 liJc6) the deceptively ambitious move 6 .i.e2. If Black then tries to delay exchanging pawns on d4 for too long (6 . . .lLlf6 7 0-0 .i.e7), White has the thematic plan of 8 c4 ! 'ii'd8 9 dxc5 'ii'xd l 10 l:.xd 1 (Game 1 5). Again a typical c3 Sicilian for mation is reached, where White has that slight but nagging endgame edge on account of his queenside pawn majority. Therefore Black usu ally exchanges pawns in the centre, and after 7 ...cxd4 8 cxd4 .i.e7 9 lLlc3 must decide where to retreat his queen. 9 . . .'i'd8 10 .i.e3 0-0 1 1 lLle5 ! ? is the subject of Game 1 6.

As Black is refusing to exchange on d4, White frees the c3-square himself for his queen's knight. The kind of ending that now results is typical of many c3 Sicilian lines; White has a useful queenside pawn majority to advance, and real pros pects of a long-term endgame edge. On the plus side for Black, the open d-file means some major piece ex changes are almost inevitable, which helps ease the defence.

�f6 (D)

As the title of the chapter sug gests, here we deal with lines where the move . . .�c6 is either long de layed or not played by Black. Natu rally if Black does play . . .�c6, there are often transpositions to and from other chapters. There is also another important point to note: the move 6 i.e3 !? is commonly employed to seek a transposition to Chapter I 0 (after 6 . . . cxd4 7 cxd4 �c6 8 �c3 ..d6 9 a3 i.e7 10 i.d3), and it is not clear that Black can avoid this. Game 18 deals with the modest 6 i.e2 systems. For once Black might regret not developing his queen's knight earlier, as 8 �5 ! ? is a direct

and logical exploitation. Games 19 and 20 cover the 6 �a3 lines, where postponing . . . �c6 definitely gives Black a wider choice of defences to counter ideas like �b5 and i.f4. For example, the move ... �a6 is avail able if required. However, these 6 �a3 systems are popular with White, and this is understandable when you see that the 'undeveloping' 6 .....d8 (Game 20) is the main line ! After the continuation 7 �c2 (also 7 i.f4 ! ?) White very rarely gets an isolated d pawn, as he can always recapture on d4 with either his queen or a knight. Whether to evaluate many of the re sulting positions '=' or ';!;; ' is a matter of taste. White has, in many cases, only an exceedingly modest edge; but there again, he has no weak nesses and there are few losing chances. On the whole I have as sessed these positions as equal, but if you are a higher-rated player want ing to win with Black, this is not the sort of equality you want! So if you favour the �a3 systems with White, don't necessarily be discouraged by the '=' assessments - many of these positions have play left in them. Finally, Game 21 covers 6 i.d3 lines where Black attempts to gain a tangible concession by delaying both the development of his queen's

4... e6 5 tDf3 {£jf6 deferring ... ttk6 55 knight and the exchange . . . cxd4. Af ter 6 . . . .ie7 7 0-0 0-0 White has a choice. He can concede that Black has played a clever move-order, and continue 8 .ie3 or 8 'ir'e2, when after . . . cxd4 and/or . . . tDc6 we reach posi tions examined in later chapters where White is now committed to certain systems. Or White can con tinue 8 c4 !?, with unclear play. At present this move-order looks quite playable for Black. In conclusion, as a general rule, it is sensible for Black to delay . . . tDc6 for a while as it takes some of the sting out of White's early tDa3 sys tems. However if White chooses the 6 .ie2 .ie7 7 0-0 line (with a view to a quick tDe5 !?), then 7 . . . tDc6 or 7 . . . cxd4 8 cxd4 tDc6 should be con sidered, giving a transposition to other chapters.

also seems to retain a plus after 7 ...0-0 8 tDb5, e.g. 8 ... tDa6 9 0-0 cxd4 10 tDbxd4 tDc5 1 1 c4 !

A good re sponse is the prophylactic 7 ...'ii'd8 !, when after 8 tDc2 the white bishop is less aggressively posted at e2 (rather than d3) in comparison to some other tDa3 lines. Nevertheless White is in no danger of becoming worse, as he can always recapture with a piece on d4 and avoid an isolated pawn. Please note that the actual move order of the illustrative game ( 1 e4 c5 2 tDf3 e6 3 c3 d5 4 exd5 'ii'xd5 5 .ie2 tDf6 6 0-0 .ie7 7 d4) has been changed to accommodate the above note.

Instead 8 .te3 �c6 or 8 . . .l:.d8 9 _.e2 �c6 trans poses to positions examined next chapter, where Black plays . . . �6 early on. A maj or alternative is 8 _.e2, when 8 . . . cxd4! 9 cxd4 �c6 (e.g. Braga-Karpov, Mar del Plata 1982 among many examples) is a move order that will reach positions exam ined in Chapters 8, 9 or 10 where White has already committed him self to _.e2 lines.

there are surprisingly few top-level games in the line. One explanation for this lack of games is that strong players (such as Michael Adams) are as White cur rently utilising a move-order involv ing a much earlier i.e3, with the specific intention of forcing Black to exchange early on d4. After 6 i.e3 cxd4 7 cxd4 lQc6 8 lQc3 White has avoided this whole chapter, and after 8 ... 'ilt'd6 or 8 ...'ii'd8 we reach the matic main line positions, albeit ones where the white bishop is committed to the e3-square. Game 22

Sveshnikov - Averkin USSR Ch 1973 Black's reason for delaying the central pawn exchange (with ...cxd4) is a rather familiar one. He wishes to deny White's knight use of the c3square, at least until White has made a small concession like playing i.e3 or 'ilt'e2. After either of these moves Black can safely exchange on d4, knowing that White can no longer opt for some of the very sharpest main lines of Chapters 9 and 10. This would be a near perfect strategy for Black were it not for 8 c4 !? (Game 22). Whilst this pawn advance is vir tually White's only try to punish Black for 'move-ordering' him, it re mains a respectable option. However

1 1 . ..1i'd6 is a good version of Chapter 9. However the situation af ter 1 l . ..'fi'd8 is quite important, and we should certainly note that the great Karpov has played it. We are now on the fringe of variations which start transposing into IQP (isolated queen pawn) positions that arise from completely different openings. By Chapter 10 these often surprising transpositions will be coming out of your ears, but, be warned, tempi can be both won and lost along the way !

12 i.c4 After this bishop move, just as warned, we have transposed into a tempo-down version of a Queen's Gambit Accepted (D26): 1 d4 d5 2 c4 dxc4 3 lDf3 lDf6 4 e3 e6 5 i.xc4 c5 6 0-0 lDc6 7 'ife2 cxd4 8 l:ld 1 i.e7 9 exd4 0-0 10 lDc3 lDb4. Arising from the QGA it is White to move; in the c3 Sicilian it is Black to move !

The c3 Sicilian practitioner could try to argue (assuming he is even aware of the transposition) that, as the QGA version is considered favour able for White anyway, so the loss of time is not life-threatening. Never theless for White to play a normal line a tempo down gives an odd feel ing. Unfortunately 12 i.b1 , the usual c3 Sicilian retreat square, also leaves White struggling to justify his IQP. After 1 2 . . . b6 some typical examples go: a) 13 lDe5 i.b7 14 a3 lDbd5 1 5 lDe4 lDe8 1 6 'ifc2 g 6 1 7 i.h6 lDg7 1 8 lDc6 i.xc6 19 'fi'xc6 'fi'c8 20 'ifb5 l:ld8 2 1 lDg3 'ii'b7 22 'ii'e2 i.h4 23 i.e4 'fi'e7 24 i.xg7 �xg7 + Braga Karpov, Mar del Plata 1982. b) 13 i.g5 i.b7 14 lDe5 l:lc8 15 h4 ( 1 5 a3 lDbd5 16 lDxd5 'ii'xd5 17 f3 = Panchenko) 15 ...lDbd5 16 lDxd5 'ii'xd5 17 f3 1i'd6 1 8 a3 l:lfd8 + Nun Panchenko, Hradec Kralove 198 1 . c ) 13 a 3 i.a6 1 4 'fi'e1 lDbd5 1 5 lDxd5 lDxd5 1 6 'fi'e4 lDf6 17 'ii'h4 g6 18 i.g5 l:lc8 19 i.a2 i.e2 + Velimi rovic-Inkiov, Banj a Luka 1 983 (and this game actually arose via a 2 c4 Caro Kann...).

It is extraordinary how some of these positions can arise via totally different openings (including the Centre Counter and Nimzo-Indian). For example, 9 . . .Wd8 (Game 24) will shortly become a Semi-Tarrasch Defence (ECO code D42) by trans position, an opening which arises via 1 c4 or 1 d4. Technically, therefore, some of these lines are outside the scope of the present book, but, of

course, your writer is not the kind of brutal, uncaring author who would refuse to cover them for such a pe dantic reason. However due to the mass of older references, the mate rial has had to be summarised, as these Semi-Tarrasch variations were quite popular a number of years ago. For further study, the Encyclopaedia of the Chess Openings (ECO), vol ume D, has reasonable coverage. If you do compare the move-orders, you will see that it is actually quite favourable for White to utilise the c3 Sicilian route - some of Black's best Semi-Tarrasch defensive options are unavailable, or can be easily side stepped. It is fair to say that, after 9 . . .'ii'd8, White's dynamic piece play and attacking chances clearly com pensate for the IQP, and his chances are somewhat preferable. Nowadays the active 9 . . .Wd6 is more common, and here some of the game references have arisen via the Caro-Kann Defence (ECO code B 10): 1 e4 c6 2 c4 d5 3 exd5 cxd5 4 cxd5 'ii'xd5 5 ltlc3 Wd6 6 d4 ltlf6 7 ltlf3 e6 8 .i.d3 ltlc6 9 0-0 .i.e7. If White now plays a quick a3 and .i.e3, play will transpose to the Modern Main Line (6 .i.e3) examined in the next chapter. Instead Game 25 covers sev eral perfectly playable alternatives for White. The most troublesome of these for Black to effectively counter

I have used the c3 Sicilian move-order (which gives Black fewer optio ns) in order to insert various alternatives alo ng the way.

10 a3 White's idea is to create mating threats against h7 by setting up the formatio n i.c2 and 'ii'd3 . Then if Black respo nds with the defensive . . . g6, the white queen's bishop will be able to develop from c 1 to the h6square in o ne ho p. Therefore this move-o rder is more forcing than 10 l:le l 0-0 11 a3 b6 1 2 i.c2 which gives Black the option of 12 ... i.a6!?

This is a deeply complex variation, where White often has to manoeuvre posi tionally in order to create threats, rather than just point his pieces at the kingside and lurch in. If you insist on an assessment I am afraid I am going to hide behind that classic author's phrase 'An unclear position with chances for both sides ! ' The last word is nowhere near being said on these strategically rich positions. Game 26

Rozentalis - Andersson Tilburg 1993 One of the reasons 6 .i.e3 is so popular is that it can also be played against the popular move-order 4 ...o!Df6 5 o!Df3 o!Dc6 ftrst seen back in Chapter 3. The most likely result is a transposition into the lines examined in this chapter. With 6 .i.e3 (against either move-order) White aims to force early clarification in the centre, by getting Black to exchange pawns on d4. In Game 26, Rozentalis-Anders son, we see an enterprising attempt to inhibit Black's routine develop ment with 1 1 ...c2 !?. In Game 27, Adams-Tiviakov, we explore what is now the main variation of the 2 . . . d5 defence against the c3 Sicilian, the

For the main line 1 1 0-0 see the next game. At fust glance c2 appears an odd square for the queen, since Black will shortly place a rook on the

Modern Main Line: 6 .i.e3 81 open c-file. Indeed White almost invariably subsequently moves the queen to e2, but this is not a straight forward loss of a tempo.

1 1 2 lbf6 : Early Deviations . . .

In this chapter we cover lines that do not fit in easily anywhere else, but this does not mean they are insignifi cant! Game 28, for example, features a crucially important recent idea for White to side-step the main-line po sitions (lvanchuk, Adams, Nunn and Dolmatov have all been seen on the white side). With l e4 c5 2 c3 ltlf6 3 e5 ltld5 4 ltlf3 !? lLlc6 5 .tc4 ltlb6 6 i..b 3 White intends to postpone (or omit) the central pawn advance d4 in favour of faster piece development. For the present Black has manoeu vred his way to a reasonable game, but there is still scope for new dis coveries. In Game 29 the main subject is the brilliant 8 e6 ! pawn thrust invented by Eduardas Rozentalis (after 1 e4 c5 2 c3 lLJf6 3 e5 00 4 d4 cxd4 5 cxd4 d6 6 i.c4 !? ltlb6 7 i.b5+ i.d7). Sev eral of the dapper Lithuanian grand master's most creative 2 c3 ideas are to be found in this chapter. Fortu nately for Black, the bark of 8 e6 is worse than its bite, and there are a number of subsequent continuations to reach an unclear position. Game 30 covers the related system 1 e4 c5 2 c3 ltlf6 3 e5 ltldS 4 d4 cxd4 5 i..c4 (which club-players seem fond of using) where Black plays the well known 5 ...Wc7 ! antidote. Finally, Game 3 1 covers the vari ation where White fianchettoes with

4 g3, another line to which Rozen talis has made an enormous contri bution. Whilst playable it does not give White any advantage against sensible play. Game 28

2... �f6: Early Deviations 95 a4 h6 14 .i.d2 'ii'd7 15 l:ad1 l:ad8 1 6 .i.e 1 e5 with a good game for Black, Short-Kasparov, London rpd 1993 . In Beating the Anti-Sicilians Gal lagher makes the claim that ''White is in fact playing a King's Indian At tack but with a tempo less than nor mal. For example, take the moves 1 e4 c5 2 �f3 e6 3 d3 �6 4 g3 d5 5 �bd2 .i.d6 6 .i.g2 �ge7 7 0-0 0-0 8 exd5 �xd5 9 c3 and you will notice that we have the same position as in Short-Kasparov, apart from the fact that White has an extra �bd2 - and this is Short's next move!" Joe con cludes: "If this is the best White can do I don't predict a very bright future for the Rozentalis variation." Whilst the comparison is well spotted, the logic is unconvincing. True, if both sides played in a certain way in the KIA you could reach that position - but they don't. Black, for example, would recapture on d5 with the pawn on move eight, not the knight. A database sweep did not re veal any King's Indian Attack games that used the moves or reached the position given by Gallagher, so the claim of a transposition is unrea sonable. The c3 Sicilian player could as easily argue that, by investing a mere tempo, he has forced Black into an unfavourable line of the KIA! However, I won't argue with Joe's overall assessment, since Black does reach comfortable equality. The other way to play is 9 d4 and now: a) 9 ... �e7 10 dxc5 .i.xc5 1 1 'ii'e2 �g6 1 2 h4 ;!; M.Makarov-Filipov, Moscow 1994.

Remarkably little of interest has happened in these 'iixd4 lines re足 cently, and there is no change to the old conclusion that these lines give White nothing. After 5 ...e6 the move 6 J.c4 (Game 3 1 ) is easily parried, while in the main line, 6 lbf3 lbc6 7 'ife4, Black has a very pleasant choice of defences: 7 ...d6 (Game 33) and 7 ... f5 (games 33 and 34). Black's extra central pawn even gives him good prospects on a medium-term edge. The old rule of thumb about not developing your queen too early does seem to apply here. Nevertheless, I recommend a careful study of the lines in this chapter, since these lines are still popular at club level.

6 i.c4 For the more usual 6 lbf3 see Games 32, 33 and 34. White's idea in playing 6 i.c4 is clear enough - he wants to force the centralised black

3 e5 t:Dd5 4 d4 cxd4 5 'ii'xd4 99 knight to move, or enter the line 6...�6 7 1i'e4 f5? ! 8 'ii'e2 where his bishop is not hemmed in on f1 (as occurs in some similar variations af ter 6 li)f3). Unfortunately this plan is not ef fective for two reasons. The first is that the black knight can often de centralise itself rather effectively by ... ti)de7 and ...li)g6, putting pres sure on the white e-pawn. The sec ond reason is that the bishop move does not threaten much in the line 6 . . . li)c6 7 'ii'e4 d6!?. White would simply get the worse endgame by capturing on d5, and his c4-bishop is often harassed by the opposing knights.

c5 lDf6 lDd5 cxd4 e6 d6 (D)

For some reason this line is not very fashionable for Black, even though he can also reach it via White's modem move-order (5 lbf3 e6!? 6 cxd4 d6). Much of the time, when Black does utilise this defen sive system, it is because he has been tricked into it - for example, 1 e4 c5 2 lDf3 e6 3 c3 lDf6 4 e5, and, as ...e6 has already been played, the main lines of later chapters are not an op tion any more. Speaking of tricky transpositions, here is one you prob ably haven't seen before: 1 e4 lDf6 2 e5 lDd.s 3 c4 lDb6 4 c5 lDd.s 5 £c4 e6 6 d4 d6 7 cxd6 cxd6 8 lDf3. The

Chase variation of the Alekhine has metamorphosed into a c3 Sicilian ! This position is covered in the £c4 note to White's seventh move in Chandler-Kasparov below. [Editor's

note: There are quite a lot of trans positions between the Ale/chine and c3 Sicilian, e.g. 1 e4 lDf6 2 e5 liJd5 3 £c4 lDb6 4 £b3 c5 5 c3 c4 6 £c2 lDc6 7 lDf3 (= 1 e4 c5 2 c3 lDf6 3 e5 li:Jd5 4 lDf3 lDc6 5 £c4 lDb6 6 £b3 c4 7 £c2) and 1 e4 lDf6 2 e5 lDd5 3 c4 lDb6 4 c5 lDd5 5 lDc3 c6 6 t&d5 cxd5 7 d4 d6 8 cxd6 exd6 9 lDf3 lDc6 (= 1 e4 c5 2 c3 lQ{6 3 e5 lDd5 4 d4 cxd4 5 lDf3 e6 6 cxd4 lDc6 7 lDc3 d6 8 l'fu:d5 exd5) being two ofthe more obscure.}

The most critical test of these ...e6/...d6 variations is White's little preparatory move 7 a3, preparing £d3, when White is all geared up for kingside pressure should Black cas tle short. After the routine 7 ...lDc6 (Game 35) it can indeed be difficult for Black to generate counterplay, and this may account for the general lack of popularity of this whole vari ation. However, Black should look again at the old system with 7 ... £d7 !? (Game 36), followed by easy devel opment with ... £c6, ...lDd7 and ... £e7. True, the white bishop on d3 does remain visually impressive on

110

5 cxd4 e6 6 l'tJj3 d6 including 7 a3

the b1-h7 diagonal, but by postpon ing castling in favour of developing the queenside minor pieces, Black can take much of the venom out of White's potential kingside threats. Game 35

Chandler - Kasparov Wattignies 1976 1 e4 c5 2 cJ lbf6 3 eS rtJdS 4 d4 cxd4

The actual game had the more un usual move-order 4 ... lbc6 5 l'tJf3 cxd4 6 cxd4 e6 7 a3 d6. I have trans posed it iJt order to present the alter natives more logically.

S cxd4 e6 6 &'tJf3 d6 7 a3!?

This quiet but excellent pawn move simply prepares White to de velop his bishop on d3, without fear of molestation from ...l'tJb4. Com bined with the white pawn wedge on e5, and the general lack of black pieces on the kingside, the bishop will exert unpleasant pressure on the b1 -h7 diagonal should Black castle short. Instead 7 lbc3 will lead into a po sition examined in a later chapter (which one depends on how the game continues), while 7 exd6 .i.xd6 8 lbc3 followed by .i.d3 is quite a solid option for White if he wants. Against 7 .i.d3 lbb4 8 .i.e2 dxe5 9 a3 the zwischenzug 9 ... e4 ! was played with success for Black in Rauze Lerner, Nimes 1991 and de Haro Toth, Mar del Plata 1996. However 7 .i.c4 is a common con tinuation, when if Black continues with ... lbc6 either now or shortly, we transpose into lines examined in

Chapter 15. It is not apparent that Black can benefit especially from avoiding this transposition: a) 7 ... l'tJb6 when 8 .i.d3 and 8 .i.b3 are examined in the course of Chap ter 17, in the notes of games 48 and 49 respectively. b) 7 . . . dxe5 8 dxe5 .i.b4+ 9 .i.d2 (9 l'tJbd2 lbb6 10 0-0 lbxc4 1 1 .,a4+ l'tJc6 12 l'tJxc4 .,d3 1 3 l'tJd6+ .i.xd6 14 l:r.d1 .,a6 15 .,xa6 bxa6 16 exd6 e5 17 .i.e3 .i.d7 18 l'tJd2 ;t was Svidler-Taimanov, St Petersburg Ch 1 995) 9 ...l'tJc6 (9 ....i.e7 10 0-0 lbc6 1 1 .,e2 .,b6 1 2 lbc3 l'tJxc3 1 3 bxc3 .i.d7 14 .i.d3 l:r.d8 15 l:r.ab1 .,c7 1 6 l:r.fe1 0-0 17 lbg5 g6 18 l'tJxh7 ! was a winning sacrifice for White in Yan ovsky-Krasenkov, Voskresensk 1992) 10 0-0 .i.e7 1 1 1We2 0-0 12 lbc3 lbxc3 13 i.xc3 b6 14 lbd2 i.b7 15 lbe4 lbd4 16 .,g4 h5 17 1Wxh5 i.xe4 18 l:r.ad1 .i.c5 19 b4 i.g6 20 .,g4 .i.f5 2 1 .,f4 .,c7 22 bxc5 bxc5 23 i.xd4 cxd4 24 l:r.xd4 ± Wolff-Rot shtein, Wijk aan Zee 1993. c) 7...i.e7 8 0-0 0-0 9 1We2 (9 lbc3 l'tJxc3 10 bxc3 lbc6 1 1 i.d3 dxe5 12 dxe5 .,a5 13 .,c2 g6 14 l:r.e1 l:r.d8 15 l:r.b1 l:r.b8 1 6 .i.f4 .i.d7 17 lbd2 i.e8 18 l'tJc4 .., Sveshnikov-Saltaev, Vla divostok 1994) 9 ...i.d7 10 l'tJc3 ! l'tJxc3 1 1 bxc3 .i.c6 12 .i.f4 ! ?

ltlf3

It makes no difference if White plays 5 ltlf3, as after 5 ...e6 6 cxd4 b6 play has transposed. Therefore this counter-attacking system has the advantage, from Black's viewpoint, that it is not easy for White to avoid. Furthermore White already has to make a major decision on move seven, over whether to challenge the centralised black knight immedi ately. The less aggressive lines with 7 J..d3 and 7 a3 (Game 37) allow Black to simplify by means of either . . . i.b4+ or ...i.a6, or both, though White can usually maintain a solid position. The main lines with 7 ltlc3 ltlxc3 8 bxc3 are complex and unclear. It is

favourable for Black to slip in the important developing move 8 ...1i'c7 !, hitting the loose c3-pawn, as White invariably replies with the less useful 9 i.d2. Then the continuation 9 ...d6 10 i.d3 ltld7 1 1 0-0 is one subtle move-order that gives both sides op tions (Game 38). However, the main line is usually reached via 9 . . .i.b7 1 0 i.d3 d6 1 1 0-0 ltld7 and now 1 2 i.f4 i s covered i n Game 38, and the critical 1 2 l:r.e1 is the subject of Game 39. The pawn sacrifice 9 i.e2 is an interesting way to enliven the game immediately. In many of these lines visually the black kingside often looks a little shaky, due to a lack of defensive mi nor pieces. Black needs steady nerves, but objectively it is not that easy for White to whip up a really dangerous attack. Even in the lines where the white rook brazenly planks itself on the h-file, a timely .. .f5 ! by Black is often the key defen sive move. And, potentially, the backward c-pawn is a target for Black, so White must be careful that his initiative doesn't peter out. Note that some positions in this chapter can also be reached via dif ferent move-orders, e.g. 1 e4 c5 2 c3 ltlf6 3 e5 ltld5 4 d4 cxd4 5 ltlf3 e6 6 cxd4 d6 7 ltlc3 ltlxc3 8 bxc3 1i'c7 and if/when Black plays a later ... b6 we will transpose.

Here we examine possibilities (for both White and Black) to avoid the position reached after 7 .i.c4 lbb6 (examined in Chapter 16). The first of these deviations is the insipid 7 lbc3?! (Game 40), which typically leads to the endgame 7 ...dxe5 8 dxe5 lbxc3 9 Wxd8+ lbxd8 10 bxc3. White's modest lead in development barely compensates for his weak ened pawn structure. Furthermore Black could choose 7 ... lbxc3 8 bxc3 Wc7 9 .i.d2 lbd7 10 exd6 .i.xd6 1 1 .i.d3 b6, which is an excellent ver sion of the ...b6 systems already cov ered in Chapter 14. In Game 4 1 we see an interesting deviation for Black in 7 .i.c4 dxe5 !?,

when after 8 .i.xd5 !? (8 dxe5 is also critical) 8 ...Wxd5 9 lDc3 'iVd6 10 d5 lbd4 1 1 lbxd4 exd4 12 Wxd4 e5 Black has usually come away quite well with his bishop pair. But actually the illustrative game shows there are lit tle-appreciated dangers in the posi tion for the second player, and any route to equality is much narrower than previously thought. Finally the move 7 ...e6 is the sub ject of the remaining two illustrative games. 10 lbc3 !? (Game 43) is the most dynamic continuation, where White gains persistent pressure on the kingside in return for compro mising his queenside pawn structure. Black has reasonable defensive re sources and can certainly play the position, but - as is always the prob lem with defending your king - one inaccuracy can lead to severe prob lems. Game 40

soften up the dark squares around Black's king. Black is certainly not without defensive resources (the de viations 1 3 ...Wc7 or 15 ... ltla5 in the main line for example), and I suspect the position is objectively rather un clear.

years, and that most games now pro ceed with the move-order 5 ttlf3 (as per later chapters). There have, however, been some recent developments with the more dynamic move 8 i.b3 (which mer ited only two references in the pre vious edition, Sicilian 2 d). White has been experimenting with a specu lative pawn sacrifice (see Game 44 ), and further games are needed for evaluation - as yet the move has not been extensively tested at grandmas ter level. Game 44

Sermek - Sveshnikov Bled 1996 The former main-line position arising after 8 i.b5 dxe5 9 ttlxe5 i.d7 (games 45 and 46) gives White no advantage. This was established in some top-level Soviet Champion ship games in the 1970s, and the as sessment has not changed since. This is hardly surprising, considering that the Soviet players involved in the original games were legends such as Tal, Petrosian, Polugaevsky and Kasparov (all playing Black against Sveshnikov of course !). This line is the principal reason that White has switched his move-orders over the

This sideline (generally involving an unclear pawn sacrifice) has been the subject of some interesting atten tion in the 1 990s (for 8 i.c4 see games 45 and 46). Certainly if White could revive 8 .i.b3, the implications for the whole ...ttlf6 defence would be very considerable.

However (although often mis-assessed as ;!;, or ±) these positions with a black pawn on c6 versus a white pawn on d4 are satisfactory for Black, as the pro spective knight on d5 is stronger than its less centralised white coun terpart on c5.

With 5 00 (instead of the 5 cxd4 of Chapters 1 3 - 1 6) White intends to meet 5 ...lbc6 with the aggressive 6 i.c4 lbb6 7 ..tb3, which can occa sionally involve a pawn sacrifice. It is possible for Black to remain in solid lines similar to the earlier chap ters with the reply 5 ...e6, and indeed transpositions back to those chapters are common. However White's key point is that, via the present move order, Black cannot reach the clear equalising plan he had in Chapter 16. In Game 47 we deal with these odds and ends, with the general conclu sion being that after White should probably play an early a3 and head for Chapter 13. Otherwise White risks allowing a particularly comfortable

(and little-known) defence for Black in the sneaky move 8 ...'il'c7 ! (see the note to Black's eighth move). But in tum if Black plays routinely, as in the illustrative game, White gains a pleasant initiative. The remaining two illustrative games include coverage of lines (af ter 5 . . . lbc6 6 i.c4 lbb6 7 i.b3 d5 8 exd6) where Black does not continue with the standard recapture 8 ...'il'xd6. The pawn-grab 8 . . . dxc3 (Game 48) is obviously risky, but perhaps not completely clear. Bologan's 1 995 discovery, the fianchetto with 7 ...g6!? (Game 49), was adopted enthusiasti cally for a time, but White seems to have at least one safe route to a small edge with the continuation 8 cxd4 i.g7 9 i.f4. Game 47

Minev - Korchnoi Oslo tt 1954 1 e4 c5 2 c3 lbf6 3 e5 lbci5 4 d4 cxd4 5 lbf3 The move-order of the actual game, 5 cxd4 lbc6 6 lLlf3 e6 7 lbc3 lbxc3 8 bxc3 d6, has been altered slightly for administrative conven ience. In fact there are numerous transposition possibilities to other chapters around this point, and in some ways this game merely ties up some loose ends - both Black and

154 4 d4 cxd4 5 liJ[3 White have promising possibilities to vary early. s...e6 5 . . . !iJc6, heading for the main line, is analysed in the following game.

6 cxd4 d6 (D) Here 6...b6 !? is a transposition to Chapter 14. On 6 ... !iJc6 White may choose from several options. After 7 a3 ! (intending .i.d3), for example, Black has nothing better than 7 ...d6 with a transposition to Chapter 1 3 a move-order commonly utilised to reach that chapter. Also possible is 7 !iJc3 liJxc3 8 bxc3 d5 (8 ...d6 is the main game) and here 9 exd6 is possi ble, while 9 .i.d3 is equally pleasant for White. After 6 ...!iJc6 White can also go for systems with his bishop on c4: 7 .i.c4 !iJb6 (7 ...d6 is a transposition to Chapter 1 5 while 7 ... .i.b4+ 8 .i.d2 .i.xd2+ 9 !iJbxd2 tD.de7 10 !iJe4 ;t was Sveshnikov-Mrdjen, Pula 1990) 8 .i. b3 (8 .id3 ! ? would transpose to Preissmann-Gallagher, Swiss Cht 1995, which continued 8 ... d5 9 .i.g5 .i.e? 10 .i.xe7 Wxe7 1 1 0-0 .i.d7 12 a3 0-0 1 3 liJc3 :ac8 14 1i'd2 f5 15 exf6 .J:[xf6 16 We3 .J:[cf8 17 .!Llg5 g6 oo) 8 . . . d6 (8 ... d5 is also played) and now 9 1i'e2 is examined in Chapter 1 6, Game 44, note after Black's eighth move, while 9 exd6 is covered (by transposition) in the course of Game 48 coming up.

There are several move-orders to reach this standard position. Quite often Black has played . . . lbc6 ear lier, but if not, Black has an excellent opportunity to continue 8 ... 'ti'c7 ! in stead. The queen is developed with game of time on account of the at tack on the c3-pawn, and it becomes apparent that Black's queen's knight can be more effectively posted on

d7. Comparing analogous . . . b6 lines (Chapter 14) where Black plays the same manoeuvre; the present ver sion is very comfortable for Black: the earlier pressure on e5 will prob ably force White to exchange pawns on d6.

where it transpires that White's pieces are deceptively active. A similar theme arises in Game 5 1 , where we investigate the line 9 0-0 .i.f5 . The key point to note here is that capturing on d4 with the knight (10 ltlxd4 !) frees the f3square for White's queen. White's development is fluid and fast, and the triumphant advance of the iso lated d-pawn from d4 to d5 can scarcely be prevented. However an interesting sideline (also Game 5 1 ) is 9 ... g6 !? which deserves more tests. Game 50

Blatny - Stocek Czechoslovakia 1996 In Game 50 the move 9 ltla3 !? (with ideas of ltlb5) is a significant alternative for White to the main lines (with 9 0-0 .i.e6) of the follow ing two chapters. It is presently un clear if Black can try to transpose to those chapters with 9 ... ..te6, but he does have a forthright attempt at refutation in the pawn grabbing 9 ... dxc3. Perhaps Black should brave these (most likely favourable) com plications, because the cautious but very common alternative 9 ...a6 has scored quite well for White. A sub sequent capture on d4 by White cre ates an unusual type of IQP position

pawn sacrifice on b2, soon followed by two pieces for a rook. Usually Black grabs the material and then, in good modem style, offers some back to get his kingside pieces developed.

semi-open a-file can be a penetration point for White's queen's rook. In all of these lines White quickly re-es tablishes material equality, and can exploit his lead in development with no risk of becoming worse. The con clusion is that if Black declines the pawn he is struggling for equality. Therefore we turn to 10...dxc3. In Game 57 White pursues a slightly il logical course with 1 1 tLlb5?!, as af ter the queen exchange Black's king is safe in the centre. The critical test is 1 1 'ii'e2 !? (Game 58), where White seeks long-term compensation for his sacrificed pawn. After 1 1 ..i.xb3 12 tL!b5 Black's queen drops back to b8 to stop a later .i.f4 or attack by White's rook on the d-file. Black's defensive resources appear satisfac tory at present, but White certainly has active play in many lines, and could experiment with Andrew Har ley's interesting new suggestions. ..

This is the absolute main line of the 2 . . .tL!f6 variation, where Black must make a decision whether to turn his temporary pawn advantage into a permanent one with 10 ...dxc3. In Games 55 and 56 we examine the unambitious variations where he chooses not to.

This looks rather illogical; frrst White sacrifices a pawn to exploit Black's king in the centre, and then he offers to exchange queens, reliev ing the pressure. Of course there is an idea behind the manoeuvre; White gets to cripple the black pawn structure in compensation.

Of course White could also have chosen 4 e5, transposing into an Ad vance French - this possibility alone can put Sicilian players off 2 . . . e6. In Game 59 (following 5 00 lDc6 6 i.b5) we see a direct transposition to the French Defence, Tarrasch Vari ation, ECO code C09, after either 1 0. . ..tb6 or 10 ...i.d6. The normal French Tarrasch move-order would run 1 e4 e6 2 d4 d5 3 tLxl2 c5 4 exd5 exd5 5 �gf3 �6 6 i.b5 i.d6 7 dxc5 i.xc5 8 0-0 �7 9 �b3 i.b6 (or 9 . . . i.d6) and now the transposi tion would arise if play continued 10 c3 0-0. The fact that White is re stricted to French Tarrasch lines with c3 is a point to be noted, as, given the choice, White might have preferred to delay or omit the move c3. Whilst

c3 at some stage in these French Tar rasch lines is a quite standard, it does not always represent optimum play for White. Therefore Black has rea sonable chances of equalising, but recently there has been a flurry of ac tivity in the white plan of retreating the bishop with i.d3 and i.c2, fol lowed by 'ii'd3 softening up the black kingside. The next three games show that there can, however, be advantages for White in utilising the c3 Sicilian move-order. In Game 60 (with 6 i.e2) similar positions to the pre vious game arise where the bishop is not badly posted on the modest e2square. In Game 6 1 (with 6 i.e3) White forces a clarification of the central pawn structure, but the most exciting and creative plan against Black's 2 ...e6 defence is to be found in Game 62, where the move 5 i.e3 ! ? gives an untypical and very dynamic structure. White does not place his king's knight on f3. Instead the square is reserved for his queen, and this unusual plan has posed Black some fresh problems. Game 59

Of course in the illustrative game Black could also have continued 10 ... i.d6 giving a French Tarrasch position where Black has reasonable

prospects for equality, but there is plenty of play.

There has been a great deal of ac tivity in the . . .d6 systems, and sev eral variations have similarities or transpositions to branches of the Pirc/Modern or Samisch King's In dian defences. After 3 d4 �f6 White must decide how to deal with the threat to his e-pawn. In Game 63 we examine the least-played of the three major options, 4 f3. In fact White's intentions are deceptively aggressive (after lbc3, ..te3 and 'ii'd2 he will castle queenside and seek a kingside attack); however Black has a fair choice of defensive set-ups to choose from, and even in the illustrative game could probably obtain reason able counterplay. 4 dxc5 (Game 64) allows Black to show his clever idea of 4 . . . �c6 ! 5 f3 d5 !?. The critical assessment comes after 9 . . . ..te7, where Black

has sacrificed a pawn for long-term compensation. In the next two games we examine the main line, 4 ..td3. White is better after the pseudo queen offer 4 ...�c6 5 �f3 ..tg4 6 d5 �e5 7 �xeS ! (Game 65), so Black often fianchet toes with 4 . . .cxd4 5 cxd4 g6 6 �3 ..tg7 (Game 66). It seems that White can keep an edge, but both sides have a wide variety of plans in this some what amorphous system, and the complex positions that result may suit a strong player trying to win with Black. Game 63

Rausis - A.Sokolov Moscow 1992 1 e4 c5 2 c3 d6 For historical record the actual move-order of this illustrative game was the less common 2 ... g6 3 d4 cxd4 4 cxd4 ..tg7 5 �c3 d6 6 ..te3 �f6 7 f3.

3 d4 lbf6 Attacking the e-pawn immedi ately is an important part of Black's strategy if he is not to be left with a passive game. a) The premature exchange of pawns with 3 ...cxd4?! 4 cxd4 frees the c3-square for White's knight a move too early (as now if 4 ...�f6 White can respond 5 �3). Even so

206 2... d6 this is not an uncommon exchange amongst lower-ranked players, al though White gains easy develop ment and a pleasant choice of lines, e.g.: a 1 ) 4 ... lbf6 5 lbc3 g6 and now 6 .i.d3 transposes to Game 66, and so can 6 �f3 if White choose to place his bishop on d3 later. 6 .i.b5+!? is an option, though after 6 ....i.d7 7 1i'e2 lbc6 8 t0f3 a6 9 .i.xc6 .i.xc6 10 0-0 .i.g7 1 1 d5 .i.d7 12 h3 0-0 13 a4 Black equalised with 1 3 ... b5 ! 14 axb5 axb5 1 5 J:r.xa8 1i'xa8 1 6 'ifd3 b4 1 7 lbe2 .i.c8 112-112 in Rai�evic-Kla ric, Geneva 1 989. a2) 4 ... g6 5 lbc3 .i.g7 6 lbf3 (6 .i.e3 a6 7 J:r.c 1 lDf6 8 h3 0-0 9 lbf3 b5 10 .i.d3 .i.b7 ao Godena-Guevara, Moscow OL 1 994) 6...lbf6 7 .i.b5+!?

Natural (but never theless inaccurate) moves by White can result in Black successfully ex changing his knight for bishop with the manoeuvre tlX6-b4xd3. 2 ... e5 !? has become a tenacious defence: after 3 ltlf3 tlX6 4 i..c4 the clever 4 ...1i'c7 ! ? means that White's ltlg5 attacks can be answered by . . .ltld8. White can choose between quiet Lopez-like manoeuvres (d3, a4, ltlbd2-fl-e3) or choosing the mo ment to blast the game open with ltlg5 and f4 in some position. Fur ther tests are needed. Game 67

Then White plays a standard strategy of manoeuvring his queen 's knight round to e3 to control the d5square. c3) 7 i.b3 is also common idea in these types of positions as a pro phylactic measure against ... llJa5.
