Preface Way back in 1982, the question "What am I going to do against the king's pawn?" became an utter torment for me. The openings of my youth - Ruy Lopez and Sicilian - were affected by some "holes" that were difficult to plug, and the problem of choosing a new defence was nothing short of a life-and- death matter! It was then that I decided to join that large group of strong grandmasters who cannot imagine life without the French Defence - and I have never regretted this decision! In my view, the French Defence is like a beautiful, proud lady who doesn't give her heart away easily. You may spend hours on end in the study of long and complicated variations, but that isn't enough to grasp all the secrets of this difficult opening. You have to devote yourself to it "heart and soul" - only then, perhaps, will you penetrate its numerous mysteries. It is quite impossible even to begin learning the French without studying some memorable games by great masters of the past such as Nimzowitsch, Botvinnik and Petrosian. I have also had much pleasure analysing games by contemporary players - names that spring to mind are Korchnoi, Uhlmann, Vaganian, Yusupov, Mikhail Gurevich, Shirov, Anand and many, many more. In general it shouldn't be forgotten that the essential struggle in these games takes place not in the opening itself but in the complex, intricate labyrinths of the middlegame. The French is less exposed to the winds of chess fashion than, say, the Najdorf Variation of the Sicilian. I have nonetheless endeavoured to provide up-to-date material, although considering the speed at which theory develops today, the reader must be alert and indeed wary - for by the time this book comes out, the assessment of some variations may have turned a full 180 degrees. It is owing to the sheer rate of expansion of French Defence theory in recent years that three books are now required to deal with the whole opening, compared to just one as was the case with my earlier The Complete French, published in 1992. The present work deals with the ever popular Tarrasch Variation, 3 tiJd2. A second volume will analyse some rare lines (2 d3, 2 'iV e2 etc.) as well as the Exchange Variation (3 exdS exdS) and the currently fashionable Advance Variation, 3 eS. A third volume will be devoted to 3 4Jc3. In conclusion, I would like to wish you as much pleasure from reading this book as I had from writing it, even though it was an extremely difficult labour! I hope the book will help you in your study of this rich opening which, in my view, is called a defence only through a misunderstanding. Lev Psakhis Rishon Ie Zion, Israel March 2003

1: Rare Continuations and 3...iLe7 Tischbierek - Hertneck German Championship, Altenkirchen 2001 1 e4 e6 2 d4 d5 3 lDd2 Doctor Tarrasch' s move, which White has been using successfully for over 100 years now, and which has thus withstood the hardest test - that of time. With 3 lDd2 White is not laying claim to a large advantage (if that is his aim he must turn to 3 lDc3), but attempting first and foremost to limit the counterplay which his opponent can hope for in the case of, say, 3 lDc3 iL b4. Among the great adherents of this move, I should first name Anatoly Karpov, although these days, unfortunately, he has given up 1 e4. The Tarrasch Variation is very successfully employed by Tiviakov and Rublevsky. Perhaps the only defect of the move is that White is exerting no great pressure on the centre and thus allows Black to carry out the freeing advance c7-c5. In this chapter, and in the present game in particular, I shall examine some comparatively rare continuat- ions for Black. (The only one that stands out, perhaps, is 3...iLe7!?) The analysis of the most popular replies (3...lDf6 and 3...c5) will be given in later chapters. 3...b6 Probably the most popular of the "second-rate" moves. Practice has also seen: (A) 3...lDe7 4 lDgf3 Maintaining the tension in the centre. Black's task is simpler after 4 e5 ltJfS 5 c3 c5, let alone after 4 exd5 exd5. White has a slight advantage after 4 iLd3 c5 5 dxc5 lDd7 6 lDb3 tlJxc5 7 tUxc5 'iYa5+ 8 iLd2 'iYxc5 9 lDf3 dxe4 10 iLxe4, V ogt - Garcia Gonzales, Cienfuegos 1976. 4...lDd7 In reply to 4...tUg6 White has the pleasant choice between 5 e5 and 5 h4!?

The dubious 4...g6?!, with its serious weakening of the dark squares, is well enough answered by 5 h4!?, with the sample continuation: 5...h6 6 h5 g5 7 e5 c5 8 c3 cxd4 9 cxd4 lDbc6 10 lDb3 6 11 iLd3 + Geller-Makarov, Ukrainian Ch, Kiev 1959. 5 iLd3

(B) 3...f5 Is it worth weakening eS like this, without cause or justification? 4 exf5 exf5 5 tlJdf3! White's other knight will be excellently placed on e2. Instead, 5 tLJgfJ more or less lets the advantage slip: S...l2Jf6 6 iLd3 (or 6 c4 iLd6 7 cxdS 0-0 8 iLe2 tDxdS 9 0-0 <it>h8 10 el i.e6= Geller-Benko, Cura9ao ct 1962) 6...iLd6 7 0-0 0-0 8 c3 tLJc6 9 b4 <it>h8 10 bS tLJe7 11 tLJeS 'iie8 12 el tLJe400 Gufeld-Gusev, Moscow 1970. 5...tLJf6 6 iLd3 iLd6 White also has an obvious advantage after 6...iLe7 7 iLgS tLJe4 8 iLxe7 'iixe7 9 tLJe2 4+ (9...0-0 10 O-O) 10 c3 'iYxb2 11 0-0 0-0 12 c4 dxc4 13 iLxc4+ <it>h8 14 b 1 'iVa3 IS tLJeS, Karpov-Enevoldsen, Skopje 01 1972. 7 tLJe2 0-0 8 0-0 4Je4 Or 8... tLJc6 9 c4 tLJb4 10 cS tLJxd3 11 'iYxd3 iLe7 12 b4 'iie8 13 tLJf4 Bradvarevic- Milic, Yugoslav Ch, Sombor 1957. 9 c4 c6 10 'iib3 <it>h8 11 tLJc3 dxc4 12 iLxc4 tLJxc3 13 bxc3 f4 14 iLa3 + .

(D) 3...h6 I didn't believe my eyes when I saw this move appearing in games by strong players. Black doesn't want to commit himself to any plan, and makes a defiant waiting move which may prove useful or hannful, as the case may be! 4 ltJgf3 ltJf6 5 iLd3 It is quite possible that S eS is stronger. 5...c5 6 dxc5 Black has a good game after 6 c3 cxd4 7 cxd4 dxe4 8 tLJxe4 iLb4+ 9 iLd2 iLxd2+ 10 'iYxd2 4Jxe4 11 iLxe4 tlJd7 12 0-0 tLJf6= Nevednichy-Eingom, Bad Worishofen open 2002. 6...dxe4 7 tLJxe4 t2Jxe4 8 iLxe4 xdl + 9 <it>xdl iLxc5 10 <it>e2 0-0 11 iLe3 i.xe3 12 <it>xe3 with chances of a minimal advantage; Marciano- Bricard, French Ch, Narbonne 1997.

The pawn structure here is highly reminiscent of the Queen's Gambit Accepted. 6...c5 7 c3 ltJc6 Usually this type of position arises from a different variation, highly popular in our own day: 3 4Jd2 ttJf6 4 eS ltJfd7 S c3 cS 6 iLd3 ltJc6 7 0-0. In comparision with that line, Black has now made the move a7-a6, which is of no great use (though it is not directly harmful, which is something!). However, the closed nature of the position gives him a right to such eccentricities, 
and it isn't at all easy for White to exploit the extra tempo. 8 0-0 iLe7 More effective than 8.. :iib6, which allows White to gain the advantage with 9 dxc5 'VJic7 (or 9.ooiLxc5 10 'it' e2 f6 11 exf6 l2Jxf6 12 l2Jb3 iLd6 13 l2Jbd4 ttJxd4 14 cxd4 Zakic- Rosenthal, Budapest 1991) 10 ttJb3 ttJxcS 11 ttJxc5 iLxc5 12 e 1 iLd7 13 'VJie2 !iLa7 14 iLf4 Coenen- Kuijf, Bundesliga 2001.

In the first edition of this book I devoted literally just a few lines to this move, but eleven years is a long time, and in the interim period 3...i..e7!? has experienced a genuine boom. In the right hands it has become a formidable weapon! The well-known innovator Oleg Romanishin was the first to employ it in top-class chess with varying success, but in the last few years many elite players have incorpor- 
ated it in their repertoire. In my view, Morozevich and Lputian have contributed the greatest number of new ideas to the theory of the variation. The main idea of 3....i.e7 is that Black first wants to see what plan White will adopt, before deciding on a corresponding course of action. Another point of some significance is that in this line Black avoids the numerous exchanges that can occur following 3...cS. 4 .i.d3 One of the most popular replies, and, for Black, one of the most dangerous. Two others that merit serious attention are 4 li)gf3 and 4 eS!? The latter will be examined in the next game. We will now look at the alternatives. (A) Obviously 4 exdS exdS S .i.d3 ltJf6 sets Black no real problems and basically steers towards the Exchange Variation. (B) 4 c3!? is a good deal more interesting. 4...cS The usual answer although of course 4...dxe4 S ltJxe4 is perfectly playable too, leading to positions very similar to the Rubinstein Variation.

Practically all Black's moves deserve exclamation marks. White is already defenceless. 26 fe1 f4! 27 iVe3 h4+ 0-1 Morozevich avenged himself brilliantly for his defeat in the preVIOUS game. 
2: 3 'Dd2 ttJc6 (C03-C04) Simic - Sermek Maribor 1998 1 e4 e6 2 d4 d5 3 tbd2 lbc6 This somewhat strange move is far from new. In the far-off 1920s it found a place in the opening repertoire of Aron Nimzowitsch, \vho never neglected a chance to play something original! Aftetwards it cropped up now and again in games by such strong players as Boleslavsky, Bronstein, Korchnoi and Vaganian, but never became truly popular. All the same it cannot be dismissed as a "marginal" line. In our own day its appearances in tournament practice are not so rare; it occurs particularly often in the games of Rogers, Kruppa and the young Russian player Riazantsev. To be quite honest, I don't have all that high an opinion of 3...tbc6. I didn't like it in 1991 when I was working on The Complete French, and I still don't! But that is just my personal opinion with which anyone is entitled to disagree, and to retain the same degree of comprehensive- ness as my earlier work all more or less significant variations should be analysed. Therefore this variation will be accorded no less attention than any other, including some more popular ones. But aside from any subjective condemnation, this move does prove to have some purely technical defects. The chief one is that by placing his knight on c6, Black is either renouncing his natural counterplay based on c7-cS, or at any rate postponing it for quite a long time. Yet any coin has two sides, and it is also possible to look for some merit in this variation. In the first place there is the complex and original nature of the ensuing positions (though I'm not convinced that everyone would take that for a merit!); and secondly, in playing this move you can be one hundred per cent sure that your opponent will not have spent entire days and nights analysing it. 4 c3 The second most popular reply. White's most frequent choice is 4 tbgf3, which will be analysed in detail in the notes to the next game, Kupreichik-B6hm. The text move gives Black the opportunity to open up the centre, but contains more than a drop of poison. 
32 3 1:i:Jd2 1:i:Jc6 Black isn't set any real problems by 4 i.b5 a6 Simplest; after 4 1:i:Jf6 5 e5 1:i:Jd7 6 c3 ttJb6 7 f4 i.d7 8 i.d3 1:i:Ja5 9 1:i:Je2 g6 10 1:i:JB, as in Palac-Naumkin, Montecatini Terme open 2000, White's spatial advantage ensures him a lasting initiative. 5 i.xc6+ bxc6 6 1:i:Jgf3 c5 7 0-0 1:i:Jf6 8 exd5 'it'xd5 9 c4 'it'd6 10 dxc5 'it'xc5= Rausis-Naumkin, Porto San Giorgio open 2001. 4...e5 Logical and strong. In accordance with classical precepts, Black goes into battle in the centre of the board and obtains very substantial equalizing chances. Let us look at the alternatives: - (A) On 4...1:i:Jh6, White can obtain an excellent game in various ways, e.g. 5 e5 1:i:Jf5 6 1:i:Jgf3 iJ..e7 7 iJ..d3 g6 8 0-0 h5 9 :tel b6 10 1:i:Jn iJ..b7 11 g3, guaranteeing him a clear plus with no prospect of counterplay for his opponent; Gipslis- Y offie, Belgrade 1968. (B) 4...f5 doesn't bring Black much joy either: 5 exf5 Apart from this, White can very well close the centre, hoping to utilize his palpable advantage in space; for example 5 e5 1:i:Jh6 6 1:i:JdB! 1:i:Jf7 7 h4 i.d7 8 i.d3 i.e7 9 1:i:Je2 1:i:Ja5 10 1:i:Jf4 g6 11 'it'e2;t Kaplinsky-Gusev, USSR 1967. 5...exf5 6 i.d3 Black's defensive task is a little easier after 6 i.b5 1:i:Jf6 7 1:i:JdB i.d6 8 1:i:Je2 0-0 9 0-0 1:i:Je7! 10 1:i:Jf4 c6. 6...i.d6 7 1:i:Je2! 1:i:Jge7 8 1:i:Jf3 0-0 9 'it' c2! 'it' e8 10 i.d2 i.d7 11 0-0-0, Keres- Petrosian, USSR Ch, Moscow 1950; Black has no compensation at all for the weakness in the e-file. (C) A rather more popular line is 4...dxe4 5 1:i:Jxe4, which recalls the Rubinstein Variation - though it isn't so simple to explain what the black knight is doing on c6 in such a position! 5...1:i:Jf6 On 5...'it'd5, White's simplest choice is 6 1:i:Jd2 e5 7 1:i:JgfJ, transposing into the Simic- Sermek game; instead 6 1:i:Jg3 promises no advantage after 6...e5, while the complications arising from 6 i.d3 e5 7 'it' e2 i.e6 are none too clear, for instance: 8 1:i:Jg5 (or 8 1:i:JB exd4 9 0-0 0-0-0 10 1:i:Jd4 1:i:Jxd4 11 cxd4 'it'xd4) 8...exd4 9 i.e4 'it'd7 10 ltJe6 fxe6 11 'it'h5+ g6 12 iJ..xg6+ hxg6 13 'it'xh8 0-0-0 14 iJ..g5 dxc3 15 bxc3 i.e7, Yanovsky- Muratov, Moscow Ch 1988. 6 1:i:Jxf6+ 'it'xf6 7 1:i:Jf3 h6 8 i.b5 iJ..d7 9 0-0 i.d6 10 'it'e2 0-0-0 11 1:i:Jd2! <&itb8 12 1:i:Je4 with a strong initiative for White; Jansa- Johannsson, Dubai 01 1986. (D) 4...1:i:Jf6 Merely provoking White into a gain of space that cannot be unfavourable to him. 5 e5 1:i:Jd7 6 i.d3 f5 Black is not in a position to offer prolonged resistance after 6...i.e7 7 1:i:JdB 0-0 8 h4! f6 9 1:i:Jg5 + Dahne-Bostra, Germany 1967. 7 g4!? White takes the bull by the horns at once, in the hope of exploiting Black's development problems; in addition, the relatively quiet 7 1:i:Je2 1:i:Jb6 8 1:i:Jf4 g6 9 h4 'it'e7, as in Klinger- Rogers, Biel 1986, promises Black no easy time after 10 g4!?

S...i¥xdS 6 CiJgfJ Clearly, after the timid 6 dxeS it is White who has to worty about maintaining the balance. Black recaptures with 6...CiJxeS, and answers 7 CiJgfJ with 7...i.g4 Of course Black also has a good game after 7.. .CiJd3+ 8 i.xd3 i¥xd3. 8 i.e2 0-0-0 9 0-0 i.d6 10 CiJxeS xe2 11 i¥xe2 i.xeS 12 CiJxfJ i.d6, V asquez- Zarnicki, Rio Gallegos 1986. White's troubles are only beginning. 6...exd4 Against the blatantly weak 6...i.g4?!, White has little difficulty securing an advantage. He answers with 7 i.c4 i.xfJ Actually, Black may be able to put up more stubborn resistance with 7...i¥d7, when White has the pleasant choice between 8 dxe5 0-0-0 9 i¥a4, and 8 d5 - with the better game in either case. But who wants to think about "stubborn resistance" after a mere seven moves? 8 i¥b3! Now Black is already at a loss for a good continuation, for instance: 8...i¥d7 8...CiJaS 9 a4+ i¥d7 is immediately refuted by 10 i.xf7+ <iftd8 11 i¥xd7+ <iftxd7 12 CiJf3 exd4 13 CiJxd4+- Keres- Botvinnik, USSR Ch, Moscow 1955; this may well be the worst game in the great Botvinnik's long career. 9 CiJfJ exd4 After 9...0-0-0 Black is in a very bad way: 1 0 f7 exd4 11 0-0 CiJa5 12 i¥ e6 i.d6 13 CiJd4 1-0 Emms-Zhang, Beijing 1993. 10 0-0 CiJaS 11 i.xf7+ <iftd8 12 i¥e6 i¥xe6 13 i.xe6 dxc3 14 CiJgS CiJh6 IS i.h3, Keres-Christoffel, Ziirich 1961; only a miracle can help Black now. 7 i.c4 A critical position for the fortunes of the 4 c3 line. Black has opened up the centre and even gained a pawn, but his somewhat backward development means he has to play with extreme accuracy. 7...i¥fS The most popular move, but not the only one. Now and again Black has played 7...i¥cs 8 0-0 It is worth considering 8 cxd4 CiJxd4 9 CiJxd4 i¥xd4 10 0-0 with excellent play for the pawn. 8...dxc3 9 bxc3 i.fS 10 i¥ a4 i¥ as, and now in place of 11 "iVb3 0-0-0 12 i.xf7 CiJh6 13 CiJc4 i¥a6= as in Gufeld-Vaganian, USSR 1973, Gufeld suggests 11 :e 1 + i.e7 12 "iVb3 with the initiative. 7...i¥d8 is hardly to be recommended.

36 3 CiJd2 CiJc6 xe6 13 CiJc4 CiJe7 14 i.e3 CiJd5, White already has to think seriously about defence; Miiller- Hecht, Bodensee Cup 2000. 9...fxe6 10 a4 Again, capturing on d4 with the knight gives Black no problems: 10 CiJxd4 CiJxd4 11 cxd4 0-0-0 12 a4 <t>b8 13 CiJb3 CiJe7 14 CiJc5 CiJc6== Stocek-Naumkin, C ppelle la Grande 1994. 10 0-0-0 11 ttJb3! eS!

There can follow: 11 a4 <t>b8 12 t2Jb3 CiJf6 13 il.g5 h6 14 il.h4 il.d6 15 hIac 1 g5 with mutual chances, Medina- Hecht, Biisum 1968. 11 hIe1 dS 12 a4 i.d6!

38 3 CiJd2 CiJc6 The most popular and logical move, and probably best. White doesn't let his opponent carry out the freeing move e7-e5 as easily as after 4 c3; he makes Black's task much harder. 4...t2Jf6 Without any doubt the best move in the position. Of course there are other replies at Black's disposal, but they have completely disappeared from tournament practice and I don't think it is worth devoting serious analysis to them. In answer to 4...e5, White has a perfectly simple way to . gain te advantage: after 5 Sl.b5! hIS lead In development is too great, for example S...exd4 6 0-0 d7 7 exdS CiJb4 8 'it' e2+ .i.e7 9 d6 cxd6 10 CiJd4 + F oltys- Zita, Moravska Ostrava 1946.

Slightly more popularity is enjoyed by 4...'2Jh6 and 4...g6, although they too can definitely be counted among the second-rate moves. Thus, 4...t2Jh6 does nothing at all to further Black's main strategic idea of pressurizing the enemy pawn centre, and allows White to acquire a plus by simple .meas, f?r example: 5 c3 The contInuatIon In Kasparov- Vasilenko, Baku 1974, doesn't look so convincing: 5 e5 f6 6 i.b5 i.d7 7 i.xc6 i1..xc6 8 CiJb3 CiJf7 9 i.f4 f5 10 h4 i1..e7 11 'it'd2 b6 12 c3 .i.b7 13 .i.e3 'fid7, and although of course White's position is not bad, Black's defensive resources should not be underrated either.

A very important position for the fate of the whole variation with 3...CiJc6. Black's pieces are very cramped in their activities, but we should not underestimate his counter-chances which are based on undermining the white pawn structure on the kings ide with f7 -f6, or, after some preparation, on the queens ide with c7-cS. Utilizing his space advantage, White has excellent opportunities for free- ranging piece play. His kings ide prospects are not bad; cavalry raids such as tLJf3-gS may form an essential part of his plan. On his sixth move White can choose between at least eight perfectly acceptable continuations: 6 tDb3, 6 b3, 6 c3, 6 c4, 6 g3, and three moves with his light-squared bishop. In our day, the most popular moves are 6 tDb3, 6 c3, 6 i.e2 and 6 bS. The last three will be analysed separately. 6 CiJb3 Clearing the path of the dark-squared bishop and preventing Black from carrying out the important freeing move c7-cS in the near future. Let's also take a close look at the alternatives: (A) 6 c4 A somewhat illogical move. It seems to me that White is unnecessarily handing Black control of the dS-square, and that the character of the resulting positions recalls the respectable Queen's Gambit Accepted rather than a slightly dubious variation of the French Defence. 6...dxc4 6...f6 is considerably weaker. After 7 cxdS exdS 8 i.bS a6 9 i.xc6 bxc6, White has the extremely pleasant choice between 10 a4 and 10 c2 i.b7 11 0-0 fxeS 12 dxeS cS 13 CiJb3 d4 14 i.gS i.e7 IS i.xe7 xe7 16 e6! with advantage, Gavashelishvili- Vaganian, Spartakiad 1967. 7 CiJxc4 Complex play similarly results from

White has in effect gained a tempo as a consequence of Black's knight sortie, and his key pawn on d4 is solidly defended - yet his bishop on e2 isn't particularly active; 9.. .cxd4 (the most frequent reply, but of course not the only one.

This modest-looking move combines at least two quite good ideas: in the first place, a retreat of the white bishop to b 1 bcomes more attractive, and secondly the rook supports the advance c2-c4.

White only has a slight advantage. 12 iLc2 d4 13 iLe4! dxc3 14 bxc3 ttJd7 IS iic2 h6 16 tDc4 tDcs 17 d1 iLd7 18 iLh6! and the attack is already irresistible. 3 tDd2 tDc6 51 11 tDn tDcs 12 tDg3 a6 13 iLn as 13...b5 14 b4! gives White a slight but enduring edge. 14 tDd4 iLd7 IS iig4 iin 16 f4 i.e8 17 ii.e3;!; The likely conclusion is that 6 c3!? presents Black with genuine problems. Speelman - Drasko Olympiad, Moscow 1994 1 e4 e6 2 d4 dS 2 4Jd2 ttJc6 4 ttJgf3 tDf6 S eS tDd7 6 iLe2 This move has perhaps come to be White's chief weapon against the whole 3...tDc6 variation. Subsequently, according to circumstances, White will either castle or carry out the typical manoeuvre tDd2-fl-e3, after which the knight will directly influence the fight for the centre. 6...i.e7! ? Black reckons that f7-f6 can very well be postponed for one or two moves, while from e7 his bishop can quickly and actively enter the fray. He also has at his disposal a few second-rate moves (their supporters must forgive the 
52 3 tDd2 tDc6 expression!), as well as one realistic alternative to the text: 6...f6. Let us look at them in order. The Croatian grandmaster Kovacevic has had some success with 6...a6, a move which at first sight appears pretty odd. Black takes control of the b5-square for any eventuality, and waits with interest to see what plan White will adopt. 7 lZJn White has a slight edge after 7 0-0 f6 8 exf6 fixf6 9 tDb3 iLd6 10 iLg5 fif7 11 c4 h6 12 iLh4 0-0 13 iLg3, Palac-Kovacevic, Croatian Ch 1992. 7...f6 8 exf6 tDxf6 9 tDe3 iLd6 10 0-0 0-0 11 c4 b6 12 a3 <it>h8 13 fic2 eS 14 dxeS lZJxeS, Rogic- Kovacevic, Croatian Ch, Pula 1998. Now 15 cxdS would have kept the initiative in White's hands. Another eccentric move, 6...lZJaS, was convincingly dealt with in Lobzhanidze- Vysochin, Groningen open 1996: 7 a3 cS 8 c3 cxd4 9 cxd4 tDb6 10 b3 iLd7 11 iLb2 c8 12 0-0 iLe7 13 iLd3 a6 14 fie2 with an excellent game. The last of this batch of "semi-marginal" moves is 6...b6. Black intends to get to grips with the White pawn centre only after completing his own development. 7 0-0 The verdict on the position is not so clear after 7 tDf1 iLb7 8 tDe3 f6 9 exf6 fixf6 10 tDg4 fig6 11 tDh4 fif7 12 f4 0-0-0 13 lZJf3 fif5 14 g3 tDf6 15 tDe3 fig6 16 c3 tDe4, Lobron-ReefschUiger, Bundesliga 1982. 7...iLb7 8 e1 8 c4!? is active but also has a minus side - Black takes control of d5 and also mobilizes his light-squared bishop: 8...dxc4 9 tDxc4 tDb4 10 iLg5 iLe7 11 fid2 tDd5 12 ac 1 0-0 13 a3 e8 with mutual chances, Kokorev- Riazantsev, U fa 2000. 8...iLe7 8...fie7 9 tDf1 f6?! doesn't look too promising for Black: 10 exf6 gxf6 11 c4! 0-0-0 12 cxd5 exd5 13 iLf4, and White's advantage is obvious; Ponomariov- Malakhatko, Kiev 1997. Also 8...f5 is hard to recommend in view of 9 exf6 fixf6 10 tDfl h6 11 tDe3 0-0-0 12 i.b5! i.d6 13 i.xc6 i.xc6 14 tDg4 fif5 15 tDge5 with impressive centraliz- ation, Kholmov-Panchenko, USSR 1986. 9 lZJn tDaS!? 10 c3 cS 11 i.d3 tDc6 12 a3 c4 13 i.b1?! bS, and in this closed position Black has his full share of the play; Prusikhin- Rustemov, Morso 2002. The perfectly logical 6...f6 enjoys considerable popularity. White has set up a strong pawn centre so Black attacks it, in accordance with generally accepted principles. 7 exf6 fixf6 White has an easier time after 7...tDxf6, which grants him almost complete control of the key square e5. There can follow: 8 0-0 iLd6 9 c4 (perhaps an even simpler line is 9 e 1 0-0 10 iLb5! a6?! 11 iLxc6 bxc6 12 c4! c5 13 dxc5 iLc5 14 lZJb3 iLa7 15 c5 + Psakhis-Prie, Chicago 1983; however, Black could improve with 10...iLd7) 9...0-0 (in Khalifman- Timman, Reykjavik 1991, 9...b6?! encountered virtually a forced

To conclude the examination of 7...llJxf6, I should mention that since the first edition of this work was published over ten years ago there have been practically no new games of importance for this variation. A bad sign for Black! 8 3 lbd2 lDc6 53 tDf1 An alternative to this move isn't simple to find. After, say, 8 tDb3 iLd6 9 0-0 0-0 10 i..g5 g6 11 iLh4, as in Oervishi- Kesmaecker, Istanbul 01 2000, Black could very well go in for 11...e5!? 12 dxe5 tDdxe5 13 xd5+ iLe6 14 dl h6 with very good play for the pawn. 8...i.d6 Black is taking too big a risk with 8...e5, on account of 9 tDe3!

After 8...ctJa7 9 i.d3 c5 10 c4! dxc4 11 ctJxc4 ctJc6 12 .i.e4 cxd4 13 .i.xc6 bxc6 14 ctJxd4, Black is not to be envied; Palac- N aumkin, Fonnia 1994. 9 .i.d3!? b6 10 c4! i.b7 Black is also a long way from equalizing after 10....i.a6 11 iVe2!? ctJc6 12 a3 dxc4 13 ctJxc4. 11 cxdS!? In Georgiev-Naumkin, Ano Liosio open 1997, White obtained the better game with 11 iVc2 h6 12 a3 ctJa6 13 cxd5 iLxd5 14 ctJe4 c5 15 iVe2, but the text move is even more energetic. 11...iLxdS 12 tDe4 0-0 13 ctJfgS!? h6 14 iVhS!? ctJc6 IS ctJh7! and White's attack is hard to withstand, Kantsler- Zilbennan, Rehovot 2001. (B) On the immediate 6...ctJcb8, White proceeds in a similar manner: 7 0-0 b6 8 e1 iLe7 9 ctJn! Stronger than 9 c3?! iLa6 10 iLa4 iLd3! 11 ctJfl iLg6, when the black bishop is no weaker than its oppos- ite number; Jimenez Zerquera- Suetin, Havana 1968. 9...iLa6 10 iLa4 cS 11 c3 bS 12 iLc2 ctJc6 13 dxcS! iLxcs 14 b4 iLe7 IS iLd3! with an obvious plus, Psakhis- Landerberque, Geneva 1992. (C) 6...iLe7 has hardly any independent significance, only after 7 0-0 a6 I would like to recommend 8 iLa4, when a sample continuation is: 8...ctJb6 9 iLb3 liJaS 10 c3 ctJb3 11 axb3 cS 12 dxcS iLxcs 13 b4 iLe7 14 ctJb3, with a slight edge for White; Belov-Riazantsev, Vladimir 2002. (D) Finally, in answer to 6...f6, White has a good choice between 7 0-0 fxeS 8 dxeS iLe7 9 iLxc6 bxc6 10 ctJd4 ctJxeS 11 iVhS+ ctJf7 12 ctJxc6 iVd6 13 ctJxe7 iVxe7 14 1:le1 with the initiative, Antunac- Hubner, Students 01, Dresden 1969; and 7 exf6 iixf6 8 ctJn iLd6 9 ctJe3 0-0 10 0-0, when the position is highly reminiscent of the line 6 iLe2 f6 7 exf6 iVxf6 - but the placing of White's bishop on b5 merely increases his attacking potential, Martin del Campo-Comas Fabrego, Novi Sad 01 1990. 7 iLa4!? It seems to me that this rarely-played move gives White more chances than the stereotyped exchange 7 iLxc6 bxc6, after which Black has more or less learnt how to solve his opening problems. 
There can follow: 8 tLJb3 A logical move. White declines to waste time castling, and intends to come to grips with the black queenside pawns without delay. Black has no problems after 8 c4 dxc4! 9 tLJxc4 (in Prusikhin- Pedersen, Morso 2002, White J2layed the perfectly innocuous 9 0-0 b6 10 c2 dS 11 tLJe4 cS! 12 dxcS iLb7 13 el tLJd7 14 tLJed2 tLJcs IS tLJxc4 d3) 9...tLJb6 10 tLJxb6 cxb6 11 0-0 iLe7 12 iLe3 0-0 13 tLJd2 dS 14 3 iLd7 IS acl as 16 a3 fc8 Gligoric-Szabo, Saltsjobaden izt 1948. If instead 8 0-0, Black replies with the calm 8...iLe7; on the other hand 8...cS can lead to obscure complications after 9 c4!? iLb7 10 a4 dxc4 11 tLJxc4, for instance 11...iLxB 12 gxB cxd4 13 dl cS 14 b4! iLe7 IS bxcS iLxcs 16 xd4 iLxd4 17 tLJd6+ e7 18 d4, Strelnikov-Shurkaev, Kharkov 2000. 8...aS Black wants to drive the enemy knight off its good square, and postpones opening the centre for a couple of moves. The alternative 8...cS has also been frequently seen. White usually replies 9 iLgS (obviously 9 dxcS tLJxcs 10 0-0 iLe7, or 9 aS c6!?, does not frighten Black) 9.. .iLe7 10 tLJaS (in Franco-Guimard, Buenos Aires 1977, White gained a big advantage with 10 iLxe7 xe7 11 3 tLJd2 tLJc6 59 c3 0-0 12 dxcS tLJxcs 13 tLJxcs xcS 14 d4 S IS b4 iLd7? 16 a4 6 17 xb6 cxb6 18 as bS 19 d2, but in the middle of this, Black missed an excellent tactical chance: IS...aS! 16 a4 axb4!) 10...tLJb8 (a line that deserves further practical tests is 10...tiJxeS!? 11 dxeS iLxgS 12 tLJc6  d7 13 tLJxgS h6 14 tDxf7 xf7 IS 0-0 0-0 16 d2 iLd7 17 tLJaS ab8, Yudasin-Orasko, Tbilisi 1987) 11 iLe7 e7 12 c3 (rough equality results from 12 dxcS xcS 13 d2 tLJc6 14 tLJxc6 xc6 IS 0-0 0-0 16 c3 as, Solak-Pcola, Holon 1995) 12. . .0-0 13 0-0 c4 (or 13.. . cxd4 14 cxd4 cS IS dxcS xcS 16 d2 with a slight edge) 14 b4 cxb3 IS axb3 cS 16 cl a7 17 e3 c7 18 fc 1, and Black still has a fair amount of work to do to obtain equal chances; Y emelin- Riazantsev, St Petersburg 1996. 9 iLgS Black answers 9 iLd2 with 9...cS!

Also 7...f6 promises nothing good for Black: 8 c4!? Incidentally, White also has the better chances after 8 exf6 'i¥xf6 9 .i.xc6 bxc6 10 0-0 iLd6 11 c4 0-0 12 c5 iLf4 13 l:£Jb3 eS 14 iLxf4 fixf4 IS l:£JeS l:£JxeS 16 dxeS fixeS 17 'iid2 fif6 18 l:£Jd4 iLd7 19 fe 1 , Garcia Martinez- Riazantsev, Ubeda open 2001. 8...dxc4 9 iLxc6 bxc6 10 l:£Jxc4 l:£Jb6 11 b3 'iid5 12 0-0, and Black has no compensation for the spoiling of his pawn structure. 8 iLb3 f6 This, at least, leads to a more complex game than 8...l:£JaS 9 c3 tZJxb3 10 axb3 c5 11 dxc5 tZJxc5 12 0-0 l:£Jd3 13 b4 l:£Jxc 1 14 fixc 1 .i.e7 IS l:£Jd4 iLd7 16 f4 with very good prospects for White, Pavlov- Shabala, Ukrainian Junior Ch 1999. 9 exf6 fixf6 10 c3 iLd6 11 l:£Jf1 h6 12 l:£Je3 fin 13 l:£Jg4 l:£Jf6 14 l:£Jxf6+ fixf6 15 0-0 0-0 16 l:£Je1?!

3: 3 tiJd2 tiJf6 (C05-C06) Psakhis - Kobalija Vienna open 1996 1 e4 e6 2 d4 d5 3 lZJd2 ltJf6 A sharp and complex variation, which has had, still has, and I am sure will always have its supporters. Black provokes the advance e4-e5 and thereby pennits his opponent to create a powerful pawn centre. If White succeeds in consolidating this centre, the advantage will be on his side; if not, the consequences for him may be truly catastrophic. 4 e5 Black is set no problems by 4 Sl..d3 c5 More convincing than 4...dxe4 5 ltJxe4 ltJxe4 6 Sl..xe4 c5 7 ltJfJ cxd4 8 iVxd4 iVxd4 9 ltJxd4 a6 10 f4 ltJd7 11 Sl..d2 Sl..c5 12 ltJb3 Sl..e7 13 O-O-O;t Brodsky- Malaniuk, Kherson 1989. 5 dxc5 Both 5 exd5 xd5 6 ltJgfJ cxd4 and 5 c3 cxd4 6 cxd4 dxe4 7 ltJxe4 lead to variations examined under C07, which are not all that favourable for White. 5...dxe4 6 tDxe4 ltJxe4 7 Sl..xe4 xd1 + 8 xd1 Sl..xc5 9 e2 Or 9 f4 ltJd7 1 0 e2 ltJf6 11 Sl..fJ e7=. 9...ltJc6 Another possibility is 9...f5!? 10 Sl..fJ ltJc6 11 Sl..xc6+ bxc6 12 c4 Sl..d4 13 ltJfJ Sl..f6°o Rogers-Cavendish, British Ch, Plymouth 1989. 10 ltJf3 Sl..d7 11 Sl..e3 Sl..xe3 12 xe3 h6 13 :ad1 e7 14 :d2 :hd8 15 :hd1 Sl..e8 with equal chances, Donev-Kuemin, Swiss Team Ch 2001. 4...ltJe4 The strongest move, 4...ltJfd7, will be examined in subsequent games. 4...ltJg8 is played extremely rarely, even though, of course, in the French Defence, pieces returning to their starting squares can hardly astonish anyone. 5 Sl..d3 The most logical.

The move is especially popular in Israel, mainly thanks to some improvements by Mark Tseitlin. White has to be prepared for the toughest measures in the struggle for the initiative; for example, in literally half the games with this variation, the d4-pawn is sacrificed. However, before the serious business starts, I should like to say a couple of words about 5 c4, which leads to positions highly reminiscent of the Queen's Gambit Accepted.

Unfortunately, the format of a monograph does not permit all sensible variations to be accorded sufficient attention.

In recent years the most popular move. Only 8...iib6 can compete with it, but we will examine that move in the context of the next game. Interestingly, in the modem treatment of this variation, Black is counting not so much on winning the d4-pawn as on forcing White to exchange on c5, and to this end he sometimes uses risky and extrav- agant methods!

(C) 8...g5!? A remarkable idea, irrespective of its objective value. I should add that this blow on the flank, aimed at pressurizing the White pawn centre, 
has become a stock device in the French Defence as a whole. In the first few games with this variation, Black came close to scoring 1000/0, but gradually White demonstrated that he too has his trumps. At this point he can choose between: (C1) 9 h3?! Perhaps the least successful move, completely failing to stop Black from canying out his plans. 9...h5 10 g4 White can hardly back out! He has major problems after 10 "ife2?! cxd4 11 cxd4 g4 12 hxg4 hxg4 13 tbh2 .tc5!, or 10 1:.e 1 g4 11 hxg4 hxg4 12 liJh2 g3!. 10...hxg4 11 hxg4 iib6 12 "iWa4 cxd4 13 cxd4 f6! 14 lbb3 "ifc7 15 e1 f5! + Paavilainen-Vaisser, Tallinn 1986.

White strives to attain the maximum: he sets up the extremely powerful pawn chain c3/d4/e5/f4, and thereby seizes so much space that he often simply cannot hold back! In this variation the course of the play tends to be extremely interesting, with mutual sacrifices and unconventional positional ideas. Black is compelled to strike against his opponent's centre, and nonnally has most success not with the standard queens ide play involving bS-b4, but by going into battle on the opposite wing with f7-f6 or even g7-g5 ! 5...c5

Incidentally, to avoid some of these variations that are rather unpleasant for him, Black can perfectly well play 6...cxd4!? 7 cxd4, and only then 7...lLJc6. 7... iib6 A logical move, increasing the pressure on the d4-pawn. Of course, there are quite a few other lines 3 lLJd2 lLJf6 83 available to Black at this point, and I would like to examine the following: (A) 7...e4 Black releases the tension in the centre and prepares a quick counter-attack on the queenside. 8 g4 b5 White has an excellent game after 8...hS 9 gxhS lLJb6 10 lLJe2 :IxhS 11 lLJg3 :Ih8 12 h4 ii.d7 13 hS;t Hort-Basman, Harrachov 1967. 9 lLJe2 lLJb6 10 ltJg3 a5 11 iLg2 b4 12 0-0 a4 13 a3! bxe3 14 bxe3;t Beliavsky- Bagirov, USSR 1974.

(B3) 8...lLJb6 With this move Black initiates a well thought out strategic plan. Allowing his opponent complete freedom to operate on the kings ide, he prepares to go into action on the other wing - and an essential part of his strategy is the advance of his a-pawn. 
84 3 tDd2 tDf6 White's large spatial advantage gives him hopes of seizing the initiative, but only with extremely accurate play. 9 ii.d3 On 9 g4, Black can consider 9...h5!? 10 gxh5 ii.e7.

A critical position for the fate of the variation. At this point White has the basic choice between four moves: 8 a3, 8 h4, 8 ti:Je2 and 8 g3. The two last-mentioned will be examined in subsequent games. 8 h4!? An interesting and fairly fresh idea which was introduced into practice by ex- World Champion Boris Spas sky in 1988. Funnily enough, the move has defensive functions as well as aggressive ones. In recent times Black's counterplay has rarely proceeded without g7-g5!?, and with the text move White prevents that advance for a long time. The interesting and original positions that so often arise in this variation have proved attractive to large numbers of players, though I ought to add that recently the results have been quite good for Black. The prophylactic 8 a3 is also played relatively often. 8...cxd4 Black can also try to maintain the central tension with 8...a5, for example: 9 ti:Je2 (the following plans are also of interest: 9 b3!? cxd4 10 cxd4 ii.e 7 11 ti:Je2 f6 12 h4!?00 and 9 g3 ii.e7 10 ii.h3 cxd4 11 cxd4 0-0 12 ti:Je2 f5 13 g4 'ii'd8 14 ti:Jg3 ti:Jb6 15 gxf5 exf5 16 'ii' c2 g6 17 ii.f1!

The game takes on a completely different character after

A line that deserves attention is 8...iLe7 9 h5 h6 10 a3 White's position is weakened too much by 10 g3?!. In Ghinda-Arencibia, Novi Sad 01 1990, Black obtained excellent counterplay with 10...cxd4 11 cxd4 f6 12 a3 fxe5 13 fxe5 0-0. Then 14 b4? a5! 15 b5 4Jcxe5! 16 dxe5 ltJxe5 gave him an irresistible attack. 10...cxd4 10. ..a5 allows White to stabilize his pawn structure with 11 b3!? 11 cxd4 l2Ja5!? 12 ltJe2, Zagrebelny- Luther, Schwerin 1999.

90 3 tDd2 tDf6 In The Complete French (1992) I only briefly mentioned this move, but a lot has happened since then. The line has attained fair popularity and was tested at the very highest level, albeit with varying success. This position can, incidentally, be reached by a different move-order: 3 4Jc3 tDf6 4 e5 ttJfd7 5 ttJce2!? c5 6 c3 ltJc6 7 f4 'ifb6 8 tDf3. But then, transpositions abound in this whole system! 8...f6 The move 8...i..e7 hardly has any independent significance. After, say, 9 g3, Black simply replies 9...f6!? The more creative type of player may prefer something like 9...a5, with the possible continuation 10 h4 a4 11 h3 db8 12 hS cxd4 13 cxd4 (or 13 tDexd4!?) 13...ii.d7 14 0-0 llJa5 Lalic-Speelman, Hastings 2000. 10 i..h3 cxd4 11 cxd4 O-O!? and we shall examine this variation later. Alternatively, 9 a3 f6 transposes into 8...f6 9 a3 i..e7!.

The assessment of the position is not altered by this extra pair of moves. A line occurring a good deal more often is 8...cxd4 9...cxd4 It is worth considering 9 tDexd4!?, for example 9... tDxd4 10 tDxd4 tDb8 11 i.e3 tDc6 12 i.d3 tDxd4 13 cxd4 i..d7 14 o-o;t Nunn-Howell, London 1993. 9...i..b4+ Or 9...f6 10 a3!?

A less accurate choice is 1 0 c3 i..e7 11 i..d3 0-0 12 a3 fxeS 13 4Ja4 'it'c7 14 dxe5, when Black seized the initiative with some brilliant play: 14...b5!! 15 i..xb5 i..a6! 16 i..xa6 'it' a5+ 17 tDc3 'it'xa6 18 'it'e2 iVb6 19 iVb5 g5!

To give the game independent significance, Black can choose 11.. .as (instead of 11...f6 in the last variation), for example: 12 0-0 a4 13 a3 'it'a7 14 c2 f5 15 exf6 tDxf6 Ljubojevic- Hubner, Wijk aan Zee 1986. 10 llJc3 Stronger than 10 <&t>f2 0-0 11 a3 i..e7 12 g3 f6 Kahn-Farago, Budapest 2001, or 10 i..d2 f6 11 SL.xb4 'it'xb4+ 12 'it'd2 'it'xd2+ 13 <&t>xd2 tDb6 14 ttJc3 i..d7 15 b3 <iite7 16 i..e2 i..e8 and White's edge is no more than microscopic, Chandler- Rajkovic, Vrsac 1981. 10...f6 11 a3 Sl.xc3+ Or 11...Sl.e7 12 i..d3 f5 13 Sl.e3 0-0 14 g 1 a5 15 'it' e2;t Sax-Skok, Nova Gorica open 2001. 12 bxc3 tDa5 13 a4 'it'c7 14 'it'c2, again with a small plus for White; Ehlvest- Dolmatov, Clennont- Ferrand 1989. 
9 a3!? A fashionable move. With b2-b4 White aims to cut the Gordian knot and relieve the tension in the centre. The snag is that he falls dangerously behind in development.

After the text move, the game assumes a rather different character; White is not striving for a big advantage but trying first and foremost to restrict his opponent's possibilities. 5 i.d3 is almost certain to lead to a simple transposition, except that 3 tLJd2 tLJf6 103 with 5...b6 Black may gIve the game a relatively novel direction, for instance: 6 tLJe2 On 6 e2 , Black achieves the exchange of Bishops all the same with 6...a5!.

1 04 3 Cf:Jd2 Cf:Jf6 not without justification! - to defend more easily after an exchange of light-squared bishops. To achieve this important strategic goal, Black is prepared to use up a few tempi and accept a certain backwardness in development. Accurate and powerful play is required from White if he wishes to set his opponent real problems. In his struggle for the initiative White usually chooses one of the following continuations: (A) 7 f4 This move isn't seen too often, but brings good results. 7...i.a6 8 i.b1!?

108 3 CiJd2 CiJf6 7...cxd4 In our day this is practically the only move Black ever plays, but I shall also fairly briefly review the chief alternatives - largely in order to justify the title of this work. Practice has seen: (A) 7 ..Jb8!? 8 0-0 b5 9 f4 In Geller-Bandza, USSR 1983, White seized the initiative after 9 CiJf3 b4 10 CiJf4 il.e7 11 :el a5?! 12 c4 dxc4 13 il.xc4 cxd4 14 il.xe6!, but Black's play can be improved without any trouble; he should consider 10...bxc3 11 bxc3 cxd4 12 cxd4 CiJb4 13 il.b 1 il.a6. 9...g6 10 CiJrJ b6 11 il.e3 b4 12 il.c2 il.a6 13 :f2 bxc3 14 bxc3 a5 with complex play, Solozhenkin- Bykhovsky, Moscow-Leningrad 1986. (B) The move 7 ...b6 has virtually no independent signific- ance (it occurs much more often after a preliminary exchange on d4). White simply finishes his development: 8 CiJrJ f6 After the passive 8...il.e7, White has no trouble at all in obtaining a highly Eromising position by 9 0-0 0-0 10 ltJf4. There can follow 10...<it>h8 11 il.c2 :g8 12 d3 g6 13 a3 c7 14 b4 b6 15 CiJh3 a5 16 b5 + Tarrasch- von Gottschall, Dresden 1892. 9 exf6 CiJxf6 10 0-0 il.d6 11 dxc5!? il.xc5 In the event of 11... xc5 12 CiJed40-0 13 e2 :e8 14 il.e3 a5 15 CiJg5, White's advantage is obvious; Tarrasch- Kiirschner, Nuremberg 1889. 12 b4 il.d6 13 il.e3 c7 14 CiJed4;t. (C) 7...f6 This once popular move can only be encountered today in the first rounds of open tournaments. 8 CiJf4!? White also sometimes Elays 8 exf6 CiJxf6 (or 8...xf6!? 9 ltJf3 il.d6 10 0-0 0-0 11 il.g5  f7) 9 CiJf3 il.d6 10 0-0 0-0, when Black can be satisfied with the outcome of the opening. 8...e7 9 ttJrJ It's hard for White to obtain any advantage with 9 'ii'h5+ f7! 10 exf6 (or 10 il.g6 hxg6 11 xh8 cxd4) 10...gxf60 (not 10...xh5? 11 fxg7 !) 11  xf7 + <it>xf7 12 1tJf3 cxd4 13 cxd4 il.d6 14 0-0 CiJf8 ! = Gufeld- Root, Los Angeles 1987.

Among the alternatives, the following are seen quite often: - (A) 8...tbb6 In the mid-1980s this placid move was more popular than today. 9 0-0 9 l2JB nearly always leads to a simple transposition, though some- times White tries to save time by not castling, e.g. 9...St.d7 10 a3!? as 11 c3 h6 12 h4 a4 13 i.c2 l2Je7 14 <;t>f1 i.c6 15 h3 d7 16 h5t Rogic- Jurkovic, Kastav 2002. 9...i.d7 10 l2Jf3 Another move that is no less worthy of attention, 10 f4!?, has already been examined under 5 f4. From time to time White 3 l2Jd2 l2Jf6 109 plays 10 a3, hoping to curb Black's activity on the queenside.

In our time the situation has radically changed, and the text move has become a serious competitor to the main line 9...tbxf6, which we shall examine later. We may count it among the merits of 9...xf6 that Black exerts immediate pressure on the d4-pawn and that the important advance e6-e5 is not so far off. There is just one disadvantage, albeit a substantial one: quite often the black queen becomes an object of attack for the opponent's minor pIeces. 10 tbf3 Such a natural move is often made automatically, yet it is also worth considering the gambit 10 0-0, for instance: 10...tbxd4 11 tbxd4 xd4 12 tbf3 f6 The other retreat is extremely dangerous for Black: 12...tfb6 13 tbg5! tbf6 14 .i.xh7! tbxh7 15 h5+ e7 16 f7+ with a powerful attack. 13 ..tg5 ti Black will hardly be able to organize a successful defence after 13...xb2 14 tbd4! - White's lead in development is just too great. 14

In the diagram position, which is critical for the whole variation, Black has a difficult choice to make between three quite good continuations: 11...0-0, 11...c7 and 11...6. The two last-mentioned will be examined in subsequent games. 11...0-0 12 i.f4 The most natural move. White offers the exchange of dark-squared bishops which is strategically advantageous to him, and which Black cannot very well decline. Of the large number of alternative continuations, there are two which I believe deserve detailed examin- 
ation: 12 i.g5 and 12 tDc3. Moves such as 12 b3, 12 a3, 12 h3, 12 tDg3 and the like, which ocasionally occur but are colourless and unappealing, scarcely call for serious analysis. (A) 12 i.g5 i.d7 Black also obtains quite good equalizing chances with 12...e5, for example 13 dxe5 xe5 14 xe5 i.xe5 15 ifd2 (15tDc3 ifc7! 16h3i.xc317 1:tc 1 "i'e5! 18 i.xf6 ifxf6 19 1:txc3 i.e6=) 15..:ii1J6 16 tDc3, Ptacnikova- V algardsson, Reykjavik 2001; and now 16...g4!? 17 ttJxd5 ifd4 would have promised him a good game. Another move to be seen is 12...ife8, when there can follow 13 i.f4!? (13 1:tel allows the double-edged 13...tDg4 14 h3 e5!? 15 hxg4 e4!) 13...e5!?

Finally, 12.006!? 13 tDc3!? will be examined under a different move-order: 11...6 12 c3 0-0 13 i.g5. 13 i.h4 Black is perfectly happy with 13 c 1 i.e8 14 tDg3!? 6, or 13 tDc3 i.e8 14 if e2 i.t7 15 1:tfel a6 16 a3 ifc7 17 i.xf6 gxf6 Belozerov-Maiorov, corr 1997. 13...i.e8 14 ifb1 The tactical try 14 i.xh7+? xh7 15 tDg5+ g8 16 tDxe6 meets with a tactical refutation - 16. 00i.xh2+! 17 h 1 ife7 18 tDxfS i.d6! 19 tDg3 ifxfS + Brady-Comas Fabrego, Andorra zt 1998.

Winning a pawn with 14...i.xeS IS dxeS jj'xb2 16 exf6 xc3 17 fxg7 jj'xg7 18 jj'd2 is too dangerous, in view of Black's exposed king position. 15 1:te1 i.h5 16 jj'd2 ae8 17 ac1 e7cx:> Psakhis-Shilov, Krasnoyarsk. 14 c 1 is not bad, though not all that constructive.

White usually replies 15 e1 If IS b4, it is worth thinking about 15...jj'd8, for instance: 16 cl e5 17 dxeS 4:JxeS 18 4:JxeS i.xeS, and White can't count on any real advantage; Gofshtein-Willms, Eupen rapid. 15...a6 It isn't so simple to find any other useful move. 16 l2Je5!? The most logical move, although White also has a good game after 16 c 1 'it>h8 17 h3 jj'd8 18 i.bl e7 19 4:JeS i.e8 20 f4 t Tseitlin-Brglez, corr 1990. 16...jj'c7 17 f4, and White's big spatial advantage guarantees him a pleasant game. 154Je5!? White has recently been having considerable trouble with his attempts to gain advantage from 15

Of course not IS...i.hS?! 16 i.xh7+! xh7 17 xhS xgS 18 xgS 'iVxb2 19 tDxdS! + Tseitlin-Seifert, Warsaw open 1989. 16 h3 Black is not given any serious problems by 16 xe6 i.xh2+ 17 <it;xh2 xe6 18 <it;g 1 i.hS= Liang Jinrog- Luther, Lippstadt 1997, or by 16 ii c2 i.g6 1 7 i.xg6 xg6 18 ae 1 ac8=. 16...i.e7 Or 16...i.b8!?, with similar ideas, which is not bad either. 17 a4 If 17 c2, then either 17...i.g6 or 17...h6!? 18 f3 lbhS promises Black good play. 17...i.xa4 18 xa4 f5 19 :ae1 xe3 20 fxe3 jj'd6= Ye Jiangchuan-Zhang Zhong, Shanghai 2000. 15...i.xe5 The most uncompromising move, but I would prefer the cautious IS...lZJe7 16 c2 1:c8 17 f4 g6 18 i.f2, or alternatively IS...<it;h8 16 a4 c7 17 f4 i.hS 18 e1. In either case White has a small plus. 16 dxe5 xb2 17 exf6 xe3 18 fxg7 xg7 19 d2 3 tDd2 tDf6 153 White obviously has more than adequate compensation for the pawn: the fearsome dark-squared bishop has no opposite number, and the black king is very exposed. Furthermore, even in the worst case, if White's initiative should peter out, Black will find it hard to avoid opposite-bishop positions with their inherent drawish tendencies. Black's task is simpler after 19 f4, which limits the activity of White's more important bishop. There can then follow 19...f6 20 1:b1 i.g6 21 i.xg6 1:txg6 22 1:tn Or 22 f5 xg2+ 23 <it;h 1 f8!, but of course not 23...g4? 241:tb2!+-. 22...d4 23 i.el <it;h8 24 i.b2 g8 25 'iWd2 e5+ Boleslavsky-Pietzsch, Berlin 1967. 19...1:tn More often, Black plays 19...e5 20 i.e2 The weak 20 f4? allows Black to consolidate by 20...xd3 21 'iixd3 i.g6 22 d2 i.e4 23 i.d4 g6 + Wang Pin-N.Pert, Edinburgh 1997. 20...l2Jf3+ 20...i¥g6!? 21 i.xf3 xf3 22 i.d4 g6 23 fe1 h6 24 e2 f5 25 ae1t Wittmann-Demuth, ObelWart open 2002. 20 f4 d4 21 jLf2 + White's attack develops easily and naturally, and it becomes more and more difficult for Black to find a defence against the many threats. 21...'iif6 22 f5 e5 Or 22...exfS!? 23 i.c4 + . 23 e1 <it;h8 24 i.h4 d6 25 f3 i.d7 26 i.g5 g8 27 'iih4 e7 28 1:tan d5 29 f6 e3 30 i.h6 1-0 
4: 3CDd2 c5 4CDgfJ and Rare Alternatives (C07) Spasov - Dreev Moscow Olympiad, 1994 1 e4 e6 2 d4 d5 3 ltJd2 c5 The most frequent and natural reply to 3 ltJd2. Black opens up the game in the centre, taking advantage of the none too active placing of the white knight. Except in the variation 4 exd5 jj'xd5, he is prepared to accept an isolated pawn. By way of compensation for this pawn weakness (but then, is it really weak?), he is able to develop his pieces quickly and comfortably, with genuine prospects of counter- play. White's nonnal choice is between 4 ltJgB and 4 exd5. In the present chapter we will examine the fonner. 4 tZJgfJ A popular and fashionable continuation. The play very often transposes into other systems, but by no means always; there are many variations of fully independent status. 4 dxc5 is hardly to be recommended. If White wants to play this move, he should patiently wait for the black bishop to move first. Now Black plays 4...i.xc5 in one go, with no loss of tempo. There can follow: 5 i.d3 Or 5 lZJb3 i.b6 6 i.b5+ ltJc6 7 exd5 exd5 8 a4 ltJge7 9 ltJe2 0-0 10 0-0 i.g4== Bronstein-Makarichev, Reykjavik open 1990. 5...ltJc6 6 ltJgfJ ltJf6 The alternative development of this knight, 6.. .ltJge7, is also _perfectly playable, e.g. 7 0-0 0-0 8 'We2 lZJg6 9 ltJb3 i.d6 1 0 e 1 i.d7 11 i.e3 ltJf4 12 i.xf4 i.xf4== Chistiakov- Bronstein, Moscow Ch 1946. 7 jj' e2 7 0-0 gives Black the additional possibility of 7...dxe4 8 ltJxe4 ltJxe4 9 i.xe4 jj'xdl 10 1:1xdl f6 11 c3 i.d7 12 i.e3 i.xe3 13 fxe3 e7== Rubinetti-Ivkov, Skopje 01 1972. 7...0-0 It is worth considering 7...ltJb4, for example 8 e5 ltJd7 9 ltJb3 ltJxd3+ 10 cxd3 i.e7 11 h4 h6 12 ltJfd4 ltJc5 13 h3 ltJxb3 14 ltJxb3 g6 with unclear play, Adams- Botterill, British Team Ch 1997. 8 0-0 After the over-hasty 8 e5 ltJg4 9 0-0 f6!

Here are the other two: - (A) 4...c4 I think this move makes much more sense if White has already played 4 exdS exdS, whereas now he has an interest in maintaining the tension in the centre. 5 i.e2!?

At this point Black usually plays either 10...a6!?, which will be examined later, or: 10....td7 With this move Black controls the b5-square and unambiguously reveals his wish to place his king on the queenside. Before proceeding to analyse this double-edged variation, I would like to draw your attention to some other possibilities for Black. The Hungarian grandmaster Chernin, a great expert on the whole 4...'illxd5 variation, has successfully played 10...'illc7 a few times. After 11 'ill e2 a6 it has proved very difficult for White to obtain an advantage, e.g. 12 i..gS Or 12 l2Jf3 i..d6 13 el b5 14 i..d3 i..b7 15 a4 b4 16 l2Je5 0-000 Ponomariov- Chernin, Bled 1999. 12...i..d7 13 l2Jo Or 13 i..h4 0-0-0 14 i..g3 i..d6 15 i..xd6 'iIIxd6=. 13...i..d6 14 fe1 0-0-000. This occurred in Szuk- Beliavsky, Hungarian Team Ch 1997, and now IS l2JeS already forced a level ending: lS...i..xeS 16 'iIIxeS 'iIIxc4 17 i..f4 i..bS 18 b3! l2Jd7 19 bxc4 l2JxeS 20 cxbS l2Jg6 21 i..g3 axbS 22 a4 bxa4 23 xa4 eS. 10...i..e7 is also occasionally seen. Black intends first of all to 
bring his king into safety and then to start looking for counterplay. White usually answers 11 b3 However, some other continuations also deserve attention, e.g. 11 il.e3 0-0 12 i¥f3 i¥c7 13 il.b3 il.d7 14 h3 ac8 IS !:tadl bS 16 !:tfel !:tfe8 17 f4;t Onischuk-Gulko, New York open 1998, or 11 !:tel 0-0 12 c3 eS 13 lDf3 i¥c7 14 3 il.d6 IS h3 h6 16 .te3 .td7 17 !:tadl e4 18 lDd2 l.c6 Ehlvest-Lobron, Reykjavik open 2002. 11...0-0 12 .tb2 !:td8 On 12...i¥f4?! 13 i¥e2! i¥e4 14 "i'd2!

190 31:LJd2 c5 4 exd5 'iIIxd5 (F) 11 b3!? The only move that approaches 11 c3 in popularity. White prepares to develop his bishop on b2, from where it will help to create numerous and varied threats. There can follow: 11...0-0-0!? The most uncompromising move; Black's task is a good deal more complicated if he chooses any of the alternatives. Thus for example, on 11...h5, White has at his disposal the brilliant idea 12 l2Jb5! (this looks like an oversight) 12...iVe5 13 iVel!!

On the other hand it is worth considering Geller's idea 14 a4!? l2Jg4 15 g3 a6 16 l2Jb5!? axb5 17 axb5 b8, with wild and unclear complications; Geller- aumkin, Palma de Mallorca 1989. 14...l2Jg4 It isn't often you get the chance to place your pieces so actively when playing Black!

Not at all a bad alternative to 10.. .d7. Black believes with some justification that fianchettoing his bishop will give him more in the \vay of active possibilities, and taking control of the important b5-square is an advantage anyway. The only snag I can see is that Black's development is delayed by one move. Ten years ago, the moves lO...a6 and 1 0...d7 were about equally popular, but now 10...a6 has relegated its rival to the sidelines of hess fashion. 11 b3 A good prophylactic move. The most popular reply, 11 1:te 1, will be 3 tDd2 c5 4 exd5 i¥xd5 197 analysed in the notes to the next game. Of White's other moves, the following should be mentioned: - (A) 11 a4!? A natural move, clamping down on the opponent's queens ide activity. 11...i¥c7 Preparing a standard piece configuration with i¥c7 and d6. Occasionally the passive 11...e7 is played; there can follow 12 b3 0-0 13 b2 1:td8 (13...b6?! 14 i¥B 1:tb8 15 a3 i¥xd4 16 iLxe7 e8 17 1:tfdl + ) 14 i¥B i¥c5 15 1:tfdl i¥h5 16 i¥xh5 tDxh5 17 tDB;t Larsen- Barcza, Moscow 1962.

White's plans are associated with the d5-pawn to some extent or other; he will blockade it, pressurize it, attack it. Black, for his part, needs to remember the old rule that attack is the best form of defence, and that, in addition to the weak (?) pawn, the position contains strategic factors such as open lines and active pieces. 5 ltJgfJ The other popular move, 5 b5+, will be analysed in the notes to the game Akopian-Bauer. 5...a6 Quite a good waiting move. Black prevents a check on b5, and gives his bishop, in certain circumstances, a comfortable retreat along the a7-g1 diagonal. From time to time Black plays the quite interesting 5...c4, which has the undoubted merit of not being too well investigated. Among elite players who have used this line, Korchnoi and Nikolic are especially prominent. White can probably count on no more than a small plus. Play may continue: 6 b3 The most popular reply.

For the present we shall look at some variations that have outlived their golden age and gone out of fashion. 
The pusillanimous 6 dxc5 is unworthy of serious attention. (Chessplayers with a more robust nervous system try not to give away tempi so lightly!) 6...i..xc5 7 tiJb3 i..b6 8 l2Je2 l2Jf6 9 0-0 0-0 10 i..g5 h6 11 i..h4 :e8 V arga- Vaisser, Budapest 1989. 6 l2Je2 has long since passed the peak of its popularity, but at the beginning of the 1980s it featured in the opening repertoire of Anatoly Karpov and other elite players. Personally I don't see that there is much to be said for placing the knight on e2 rather than its rightful square £3, except that sometimes White can offer an exchange of dark-squared bishops on f4. In reply, Black has several plausible continuations to choose from: - (A) Against 6...a6?! White effortlessly gains the advantage with 7 jtxc6+ bxc6 8 0-0 i..d6 9 dxc5 i..xc5 10 4Jb3 ..td6 11 !iLf4 4Jf6 12 c4! 0-0 13 cxd5 l2Jxd5 Or 13...cxd5!?;t. 14 i..xd6 xd6 15 :c1 t Konguvel-Girinath, Mumbay 1999.

White's position is preferable, whereas 10 c3 cxd4 11 g4 i..g6 12 tDxd4 O-O-O!? led to wild complications in Bronstein-Gulko, Moscow 1968. I am very fond of that game and would like to take this opportunity to reyroduce it in full: 13 a5 c7 14 a6 xd4 15 axb7+ b8 16 cxd4 !iLc2! 17 e2 h5 18 g5 g4!? 19 f4 f6 20 hxg4 hxg4 21 ..ta4? ..tf5 22 iVa6 i..c5! 23 dxc5 xc5+ 24 <&ttg2 'iie3 25 a3 i..e4+ 26 xe4 'iixe4+ 27 <&ttg3 h3+ 28 <&ttxg4 iVg2+ 29 f5 fxg5 30 xh3? :f8+ 31 g6 gxf4+ 32 <&tth7 xh3+ 33 <&ttxg7 h8+ 34 <&ttg6 g8+ 35 <&ttf5 h7+ 36 <&tte5 'ir' e4+ 3 7 d6 1:tg6+ 38 <&ttc5 1:txa6 39 i..xf4+ <&ttxb7 40 i..b5 a5 0-1. (D) Black has quite often chosen 6...i..d6, but gradually White has discovered ways to deal with this move: 7 dxc5 i..xc5 8 tLJb3 i..b6 On 8.. .!iLd6, White easily attains a major strategic goal - the exchange of dark-squared bishops - which ensures him the better chances: 9 0-0 lOge7 10 i..f4! 0-0 11 i..xc6 bxc6 12 e 1 !iLa6 13 !iLxd6 xd6 14 ltJg3 ..tc4 15 l2Jd2 c5 16 c3t Tseshkovsky-Farago, European Ch 1977.

Should he succeed in exchanging the dark-squared bishops, his advantage will be obvious. A frequent alternative to the text move is the immediate 11 c5. retaining the light-squared bishop for the present.

(B) 11 c3 ii.g4 The main difference between 11 c3 and 11 ii.d3 is that in the present case Black can immediately bring his bishop to this active square. There is little point in playing 11...a6 and driving the white bishop to a square where it wants to go anyway, e.g. 12 ii.d3 h6 13 h3 ii.f5 14 ii.e3 ii.xd3 15 ifxd3 if c7 16 a4, and White preserves a small plus as in Tseshkovsky-Dolmatov, USSR Ch, Frunze 1981. 12 ii.e2 The insertion of 12 h3 ii.h5 makes no substantial difference, e.g. 13 ii.e2 :e8 14 ltJbd4 a6 15 ii.e3 ii.c 7 16 ltJxc6 ltJxc6 17 ltJd2 ii.g6! 18 ltJfl ii.e4°o Diickstein-Beliavsky, Le Havre 1977. 12...:e8 13 ltJfd4 Or 13 ltJbd4 a6 14 ii.g5 h6 15 ii.h4 irD6 16 irD3 ii.c5! 17 iixb6 ii.xb6=

White prepares a queen sortie to a4 and hopes to force Black into an eventual knight exchange. Among the numerous moves and plans at White's disposal, the following deserve to be mentioned: - (A) 11 h3 h6 A situation we have seen before: each player wants to prevent an annoying excursion by 
his opponent's bishop. It is also worth considering 11... tDxd4!? 12 tDxd4 (or 12 iYxd4 i.f5 13 c3 i.e4 14 tDg5 tDf5 15 iYd 1 iYf6 16 e 1 i.c5 Tukmakov-Uhlmann, Hastings 1972) 12...i.c7 13 i.d3 iYd6 14 g3 iYf6 15 c3 i.b6 16 i.e3 tDc6, and Black is close to equalizing; Suta-Khasin, corr 1969. Another fairly good alternative to the text move is probably 11...i.c7, for example 12 el iYd6 13 i.g5 tDg6 14 i.f1 tDxd4 15 iYxd4 f6! 16 i.e3 tDe5cx>. 12 c3 a6 13 i.a4 i.c7 14 el iYd6 15 i.e3 i.d7 16 i.c2 fe8 17 iYd3 tDg6 with chances for both sides, Kristjansson-Gdanski, European Ch, Ohrid 2001. (B) 11 b3 A certain weakening of the dark squares on the queens ide may be counted among the defects of this natural move. 11...i.g4 It is also worth considering 11...iYa5; then after, for example, 12 i.b2 i.a3 13 i.xa3 iYxa3 14 el i.g4 15 i.xc6 tDxc6 16 iYd2 i.xB 17 tDxB ad8, Black equalized in Karaklajic-Petrosian, Belgrade 1956. 12 i.b2 'ifb6 13 i.e2 Black can be perfectly happy with 13 tDxc6 bxc6 14 iLd3 h6 15 h3 i.h5 16 i.e2 fe8 17 e 1 i.c5 18 tDd4 i.g6== Shamkovich- Vaganian, Sochi 1970. 13...fe8 14 h3 i.h5 15 iYd2 ad8 16 adl i.g6 17 fel i.c5 18 i.fl i.e4cx> Gipslis-Korchnoi, USSR Ch, Riga 1970.

(D) 11 i.g5 f6!? Perhaps the most interesting move in the position. Black hopes to bring a knight to e5 and quietly finish his development under its cover. The more conventional 11..:iWc7 leads to some complex play, e.g. 12 el (on 12 h3, it is worth considering either 12...h6, with the possible continuation 13 i.xe7 i.xe7 14 e 1 i.f6 15 c3 ilb6== Kaufman- R.Byrne, USA Ch, New York 1972; or 12...f6!?, when after 13 i.e3 tDe5 14 el a6 15 i.f1 i.d7 16 <&tthl fe8 17 i.f4 ad8 Black's chances were no worse in Wade-Bronstein, Tallinn 1971) 12...iLg4 13 iLe2 a6 14 h3 i.h5 15 c3 h6cx>.

274 3 tlJd2 c5 4 exd5 exd5 5 tlJgf3 tDc6 competition for popularity on the "opening market". The two moves are related by a major strategic aim: White considers his knight on d4 to be the best feature of his position, and wishes to give it maximum support. 11...i.g4 It doesn't pay Black to refrain from this move, which greatly restricts his opponent's possibilities. In Matulovic- Balashov, Y ugoslavia- USSR 1979, Black failed to equalize with 11...iYc7 12 h3 a6 13 i.d3 tlJg6 14 e 1 e8 15 c3 i.d7 16 'ii' c2 tlJa5 1 7 ad 1 tlJc4 18 i.cl. 12 h3 On 12 iYd2 iYc7 (another line that looks quite good for Black is 12.. .c8 13 fe 1 tlJa5!?, for instance 14 b3 tlJac6 15 h3 i.h5 16 i.e2 i.g6 17 c3 a6 18 tlJxc6 tDxc6 19 ad 1 i.e4= Matulovic-Portisch, Odzaci 1978) 13 h3, the play can transpose with 13...i.h5, but Black has an additional possibility which is not bad at all: 13...i.xB!? 14 tlJxB ad8 15 c3 tlJe5 16 tlJxe5 i.xe5 17 fe 1 a6 18 i.d3 tlJc6, and it is quite hard for White to demonstrate even a slight advantage: Sokolov- Lputian, USSR Ch, Riga 1985. 12...i.h5 Or 12...tlJxd4!? 13 i.xd4 i.h5 14 e 1 tDc6 15 i.xc6 bxc6 16 iYd3 f6 17 tlJh4 c5= Sokolov- putian, USSR Ch 1984. 13 iYd2 'We7 Or 13...c8!?, which is quite good too; Black hopes to construct a battery with i.b8 and iYd6, which will make the white king feel nervous.

A typical manoeuvre in this sort of position; the strongly placed knight on c4 will fully compensate for the weakness of the d5-pawn - which, incidentally, has not even been attacked yet, and is not likely to be attacked in the near future!

..... ,'. " Fre ch 0 " "- ','\  'e " " '" <,,..( :' \ ' . ' .... -"" -. '- . " "' Past and present, the French Defence has been and remains a popular choice against White's King's pawn opening, with top class grandmasters such as Korchnoi, Morozevich, Bareev and Short continuing to practise it with success. Since the publication of The CompLete French in 1992 - a highly acclaimed standard work on the subject - the volume of theory has increased to such an extent that the author has produced three volumes to cover the whole opening. This first volume - dealing with the sequence 1 e4 e6 2 d4 dS 3nd2 - features a wealth of illustrative games as well as up-to-date theory. Known as the 'Tarrasch variation', it has long been known to provide excellent attacking prospects for White but, as the younger generation has amply demonstrated, Black has many exciting counterattacking resources too! Grandmaster Lev Psakhis is a former Soviet champion now living in Israel. He has been a lifelong adherent of the French Defence and serves as trainer to world No 1 player Judit Polgar.
