Chapter 1: Introduction.

The Panov Attack with 5...g6 is one of the most interesting lines of the Caro-Kann, though it can also arise vvia transposition from other openings including the English, Scandinavian and Sicilian. After 1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4 Nf6 5.Nc3 g6 Black is willing to part with the pawn at d5 and not regain it for a considerable period of time.

 White does not treat the extra, doubled pawn as a material asset. Instead, its presence at d5 gives White a definite advantage in space. White will use this to build up a strong position, and then will often sacrifice the pawn by advancing it to d6. After Black captures at d6 with the e-pawn, White moves the pawn at d4 to d5, cementing the spatial advantage.

 Black can counter this strategy in a number of ways. One of the best methods is to use the light-squared bishop to command a lot of territory at f3, sometimes infiltrating to d3. Another plan is ...Bg4, exchanging light-squared bishops and making it harder to support the pawn at d5. Finally, in some cases Black can even go into an endgame where White has an extra, protected passed pawn at d4, blockaded however by a powerful knight at d5 which cannot easily be dislodged. A remarkable number of these endgames are in fact drawn.

 These strategies are so well explored that there are thousands of games available for examination. Most of the available strategies for both sides have been investigated deeply, yet there remains considerable scope for original play. I have proposed many suggested improvements in this book, far more than usual int he Panov series, because I think that the results of many games are misleading. Often the mismatched abilities of the players determine the results, not the position. Often a simple improvement reverses the verdict on a line. Of course the reader should treat all of my proposals as mere suggestions, and check them thoroughly before using them in rated play.

 The enormous number of transpositions makes it very difficult to organize the material coherently. Even with the help of sought powerful tools as Bookup, the presentation of variations in this book cannot point to each possible alternative move order. I had generally presented material using the move order that was employed in the game. The complexity of the transpositions use so great that I suggest you concentrate on learning which positions are favorable for your preferred side..

 The sheer mass of material combined with limited space has forced me to use something I rarely employ: Informant symbols for judgments. This book is necessarily rather terse, and there just wasn't room for much explanatory material. I have had to let the moves speak for themselves. This is not such a problem, because the basic tactics and strategies occur over and over in the games, and the positions in which White or Black has an advantage will soon become familiar. Although the book appears very database-oriented, the reader will find hundreds of new moves suggested in the text. This is truly a sourcebook for ideas.

 I have tried to avoid abandoning positions as unclear, though in a few cases I have done so. In addition, I have selected some positions for special attention, where the play is typical of what one finds in the middlegames or endgames which arise out of the 5...g6 Panov. Since I have had to resort to symbols, here is what I mean when I use them:

Chances are balanced. This is a satisfactory situation for Black, but not good enough as White. 
I have not investigated deeply enough to form an opinion. 
+ -  White is winning. 
- +  Black is winning. 
+/-  White has an obvious advantage that should not require explanation. I would not want to be playing Black. 
Black has an obvious advantage that should not require explanation. I would not want to be playing White. 
+=  White is a little better, but this advantage may not lead to a win without further errors on the opponent's part. I would not object too strongly to defending the Black side, but I would prefer a more reliable plan. 
=+  Black is a little better, but this advantage may not lead to a win without further errors on the opponent's part. I would not object too strongly to defending the White side, but I would prefer a more reliable plan. 
comp  There is compensation for material, but not enough to confer a serious advantage. In general, I'd prefer to be playing the side with the compensation rather than having the extra material. 
<->  There is counterplay in the position, but neither side has a clear, demonstrable advantage. I would be willing to play either side. 

Remember that these are human evaluations, and are largely impressionistic when it comes to conepts of equality or slight advantage. In preparing this book I have consulted many sources, and sometimes find myself in serious disagreement with judgments presented there. When I disagree, I have tried to extend the analysis in support of my point of view. So you will certainly find positions where my evaluation differs from others you may see. I suggest that these positions are ones which deserve careful study on your part.

 Sometimes there is not much that can be done with the slight advantage. You must gain practical experience and study the material thoroughly to develop instincts as to which positions are worth aiming for. If you play endgames well, it may be easier to hold certain positions, or win others.

 I hope that you will enjoy the fascinating positions in the 5...g6 lines of the Panov Attack. Companion volumes on 5...e6 are already available from Chess Enterprises, and the next volume in the series will deal with the 5...Nc6 lines.

Chapter 2: Misc. 6th moves for White

McGarrett Spraggett, Toronto 1993

1.e4 c6 2.c4 d5 3.exd5 cxd5 4.d4 Nf6 5.Nc3 g6.   We begin by examining the alternatives to 6.Bg5, 6.Nf3, 6.cxd5 and 6.Qb3. None of these minor moves are going to cause Black any difficulty, whether or not Black plays precisely, and they are not even mentioned in most opening manuals.Nevertheless, it is useful to examine effective plans for Black, which display the overall strategy of the fianchetto defense..


 6.Bd3 Bg7 7.Nge2 0-0 8.0-0 Nc6 9.a3 b6 10.Bg5 dxc4 11.Bxc4 Bb7 12.Rc1 Rc8 Black already has a tangible advantage. The isolated d-pawn is weak, and Black has completed development with all forces posted in useful positions, Brekka - Berg, Aabybro Nordic 1989.

 6.c5 is premature. Normally play will transpose into the lines with Nf3 and Bg5, but sometimes White tries something more original. 6...Bg7 7.Bb5+.

 A) 7...Bd7 8.Qb3 (8.Bxd7+ Qxd7 9.Bf4 Nc6 10.Nge2 0-0 11.0-0 Rfe8 12.Rc1 Rad8 13.f3 Nh5 14.Bg5 h6 15.Bh4 g5 16.Bf2 e5 17.dxe5 d4 18.Ne4 Bxe5 19.Qb3 Kg7 20.Rcd1 f5 21.N4g3 Nxg3 22.Nxg3 Bxg3 23.hxg3 Qf7 24.Qd3 Kg8 25.a3 Ne5 26.Qb5 a6 27.Qb6 Nc6 28.Rd2 Rd7 29.Rfd1 Red8 30.Rd3 = Innala - Karttunen, Finland Championship 1996) 8...0-0 9.Nf3 Bxb5 10.Nxb5 Nc6 11.0-0 Ne4 12.Rd1 Qd7 13.Nc3 Nxc3 = Grünthal - Kirjavainen, Finland Championship 1993.

 B) 7...Nc6 8.Nge2 0-0 9.0-0 e5 (9...a6 would have been a useful preliminary move.) 10.Bxc6 bxc6 11.b4 (11.dxe5 Nd7 and Black is also better.) 11...e4 12.a4 Bd7 13.b5 Rb8 14.Rb1 Nh5?! (14...Ng4 is stronger.) 15.Nf4 Nxf4 16.Bxf4 Rb7 17.Qd2 Re8 White has been allowed too much progress on the queenside, and now Black falls to a simple sacrifice which lets the pawns race down the board. 18.Nxd5! cxd5 19.c6 Rb6 (19...Bxc6 20.bxc6 Rxb1 21.Rxb1 Qh4 22.c7+/-) 20.a5 Rxc6 21.bxc6 Bxc6 22.Rb8 and White went on to win in Fattorelli-Falconieri, Postal 1990.

 6.g3 Bg7 7.Bg2 dxc4 8.Qa4+ Nbd7 9.Qxc4 0-0 is already better for Black, since the d-pawn is a target.

 6.Be3 is very passive. 6...Bg7 7.c5 Nc6 8.Bb5 0-0 9.Nf3 Bg4 10.h3 Bxf3 11.Qxf3 Ne4? (11...Qa5! and Black has the initiative.) 12.Bxc6 bxc6 13.Nxe4 dxe4 14.Qxe4 Qa5+ 15.Bd2 was a little better for White in Beals - Van Brussel, Soest 1996.


This entails a pawn sacrifice..


 7.Bd3 0-0 8.Nge2 Nc6 (8...dxc4 9.Bxc4 Qb6 looks better for Black here.) 9.0-0 Nb4 10.c5 b6 11.cxb6 Nxd3 12.b7 Bxb7 13.Qxd3 Qd7 led to an even position in Siroky - Janko, SVK Championship 1995.

 7...Rxb8 8.Qa4+ Bd7 9.Qxa7 dxc4 10.Bxc4 b5.

Black has some compensation for the pawn, with readily available targets in the center and on the qaueenside..

 11.Bb3 0-0 12.d5 Ne8!? 13.Nf3.

13...b4 13...Rc8 would have equalized. 14.Nd1 Rb6 Black has a strong but White is having no problems completing development. 15.0-0 Nd6 16.Re1 Nc8 17.Qa5 Qc7 Here White returns the pawn, for no good reason. 18.Ne3. 18.Re4 is more to the point, and Black must defend the pawn at b4. 18...Bxb2 19.d6 Qb7! 20.dxe7 Nxe7 Now Black is better. 21.Nc4 Ra6 22.Qc5 Bxa1 23.Rxe7 Bf6 24.Re1 Qb5 25.Qc7 Qc6 26.Qf4 Kg7 27.Nce5 Qc7 28.Qxb4 Be6 29.Nc4 Rb8 White resigned.

Monaco (Melody Amber) 1995

1.e4 d5 2.exd5 Nf6 3.c4 c6 4.d4 cxd5 5.Nc3 g6 6.Bg5.   Black has been able to handle this move without much difficulty..


 6...Bg7 is also good: 7.Bxf6 (7.cxd5 0-0 8.Bc4 Nbd7 9.Nf3 Nb6 10.Bb3 Nfxd5 11.0-0 Be6 12.Re1 Re8 13.Rc1 Rc8 14.Nxd5 Bxd5 15.Rxe7 Rxe7 16.Bxe7 Bxb3. Swierczewski - Pisulinski, Saitek Open 1992. 7.Nf3 transposes to 6.Nf3 Bg7 7.Bg5.) 7...Bxf6.

A) 8.Nxd5 Bg7 9.Nf3 Nc6 10.Be2 (10.Qd2 Bg4 11.Ne5 Nxe5 12.dxe5 Bxe5 13.Be2 Be6 14.Rd1 Bxd5 15.cxd5 0-0 16.0-0 Qb6 and Black is better, with attacking chances on the kingside and a target at d5 and b2. Haanpaa - Kortelainen, Finland Championship 1989.) 10...0-0 11.0-0 e6 12.Nc3 Nxd4 13.Nxd4 Qxd4 14.Qb3.

 A1) 14...Qd7 15.Rfd1 Qe7 16.Bf3 Rb8 17.Nb5 b6 18.Nd6 Rd8 19.c5 Bd7 20.Nb7 Rdc8?! (20...bxc5! would have given Black the advantage.) 21.cxb6 axb6 22.Qxb6 Ba4 23.Rdc1 Qg5 24.Rf1 Qf4 25.Qe3 Qxe3 26.fxe3 Bxb2 drawn, though Black is a little better, Clarke - Dunn, Edinburgh open 1989.

 A2) 14...Qb6 15.Rfd1 Qa5 16.Nb5 Rb8 17.a3 a6 18.Qg3 axb5 19.Qxb8 bxc4 20.Bxc4 Bxb2 21.Qg3 Bxa1 22.Rxa1 Bd7 and Black went on to win in Von thron - Schulze, Bundesliga 1987.

 B) 8.Nf3 dxc4 9.Bxc4 0-0 10.h3 Nc6 11.d5 Ne5 12.Be2 Qa5 13.0-0 Rd8 14.Qb3 Bf5= Diez - Wohlfart, Germany 1993.

 8.cxd5 8...Qb6 9.Bb5+ Bd7 (9...Nd7 10.Nge2 a6 11.Ba4 0-0 12.Bb3 Bg7 13.0-0 Nf6 14.Re1 Qd6 15.Ng3 b5 16.Re5 Qd8 17.Qe2 Bg4 18.f3 as agreed drawn in Valiente - Slipak, Buenos Aires 1988, but White is certainly better.) 10.Bxd7+ Nxd7 11.Nge2 0-0 12.0-0 Rfd8 13.Qd3 Rac8 (13...Bg7 14.Rfd1 Nf6 15.Qf3 Rd7 16.Nf4 g5 17.Nh5 Nxh5 18.Qxh5 Qxb2 and Black was much better in. Boricsev - Seres, Eger 1995.) 14.a4 Bg7 15.a5 Qa6 16.Qe3 Re8 17.g3 Rcd8 18.Nf4 Bh6 19.Qf3 Bxf4 20.Qxf4 Nf6 21.Qe5 b6 22.Ra4 bxa5 23.Rfa1 Qb7 24.Rxa5 Qxb2 was even in Smyslov-Bronstein, Soviet Union 1967.

 6...dxc4 gives up the center for no particular reason, but it is not so bad. 7.Bxc4 Bg7 8.Nf3 0-0 (8...Nbd7 9.0-0 Nb6 10.Bd3 0-0 11.Re1 Re8 12.Qd2 Bg4 13.Be2 Rc8 14.Rac1 Nbd5 15.h3 Be6 is fine for Black,. Menzel - Hofrichter, German Championship 1996.) 9.0-0.

 A) 9...Bg4 10.Re1 (10.d5 Nbd7 11.Re1 Qc7 12.Be2 Bxf3 13.Bxf3 Ne5 14.Be2 h6 15.Bf4 Rad8 16.Qd4 and White is better, Sulskis - Weiss, Aschach 1993.) 10...Nbd7 11.Qd2 Bxf3 12.gxf3 Nb6 13.Bb3 Qd7 14.Kg2 Rfe8 and Black is at least equal. Toth - Ponyi, Salgo 1979.

 B) 9...h6 10.Bf4 Nbd7 11.Re1 Nb6 12.Bb3 e6 13.Qd2 g5 14.Be5 Nfd5 15.Bc2 is moe promising for White,. Lehmann - Ree, Amsterdam IBM II 1963.


This is a reasonable defense..

 A) 7.Nf3 Bg7 transposes to 6.Nf3 Bg7 7.Bg5 with ...Nbd7.

 B) 7.cxd5 Nxd5! 8.Nxd5 Qa5+ 9.Nc3 Qxg5 is an active defense for Black. 10.Nb5 Bh6 11.Nc7+ Kf8 12.Nxa8 Qa5+ 13.Ke2 Qb5+ 14.Ke1 Qb4+ 15.Ke2 Qxb2+ 16.Kf3 (16.Kd3 Nc5+ 17.dxc5 Bf5+ 18.Kc4 Bd2! would also have won.) 16...Nf6 17.h3 Bf5 18.g4 Be4+ 19.Kg3 Bf4+ 20.Kxf4 Qxf2+ 21.Nf3 Bxf3 22.Qe1 Nd5+ 23.Ke5 f6+ 24.Ke6 Nf4+ 25.Kd7 Qxd4+. Tuvshintugs - Vajda, World Junior Championship1993.

 C) 7.Nb5 7...a6! 8.Qa4 dxc4 9.Rc1 axb5 10.Qxa8 e5 is not as sound as the result of the game indicates. 11.dxe5 (11.Bxc4! bxc4 12.Rxc4 Nb6 13.Rxc8 Bb4+ 14.Kf1 and the threat of Bxf6 gives White a decisive material advantage. 14...Qxc8 15.Qxc8+ Nxc8 16.Bxf6 Rg8 17.Bxe5 etc.) 11...Bb4+ 12.Rc3 h6 13.Bxf6 Nxf6 14.exf6 0-0 15.Ne2 Qd3 16.f3 Qb1+ 17.Kf2 Bc5+ 18.Kg3 Qe1+ 19.Kf4 Qd2+. Olafsson - Hansen, Groningen 1985.


 This modest post for the bishop does little to advance White's cause..

Bg7 (17...Kd8 18.Rxh6 Rxh6 19.Qg5+ f6 20.Qxh6 exd5 21.Qh8+ Kc7 22.Bxd7 Kxd7 23.Qxf6 would have been no worse for White.) 18.Rxh8+ Bxh8 19.Nc7+ Kd8 20.Nxa8 Qxb5 21.Qf4 Qa5+ would have been unclear. Instead, Lehmann captured at h6 and fell into a bad position.


 7...Qa5 8.Qa4+ Qxa4 9.Nxa4 e6 10.Rc1 Bd7 11.Nc3 Nxc3 12.bxc3. Zamaev - Labutin, Russian Championship J16 Kaluga 1996 and here 12...dxc4 would have been better for Black, with the bishop taking up an active post on c6.


8...Bg7 9.cxd5.

 9.Nf3 0-0 10.cxd5 Qxd5 11.Be2 Qa5 12.Qd2 b6 13.0-0 Na6 14.Bxa6 Bxa6 is slightly better for Black, thanks to the bishop pair. = Rozentalis - Malisauskas, Oslo Royal GM 1992.

 9...Qxd5 10.Qb3 Qd6 Black has no reason to want to exchange queens here. 11.Nf3 0-0 12.Be2 Nc6 13.0-0 b6 14.Rad1 Bg4.

This is a fairly typical position. Black can continue to place pressure on White's center, and White has no active plan. The pawns in the center are difficult to maintain whether they stay in place or advance. 15.c4 Rab8 16.c5 bxc5 17.dxc5 Qc7 18.Qa4 White now has a passed pawn, but it is not very strong. 18...Rb4 19.Qa6 Rb2 20.Rd2 Rfb8 Exchanging immediately and playing ...Nb4 might have been stronger. 21.Ng5 Rxd2 22.Bxd2 Bxe2 23.Qxe2 h6 24.Nf3.

Black now lets some of the advantage slop. 24...Rb2! would have tied down White's position and the a-pawn would sooner or later fall. 24...Nd4?! 25.Nxd4 Bxd4 26.Rc1 Bxc5 27.Bxh6 Black may have simply overlooked this. 27...Qd6 28.h3 Bd4 29.Be3 Qe5 30.Qd2 Bxe3 31.Qxe3 Qxe3 32.fxe3 Rb2 33.Rc7 Rxa2 34.Rxe7 Kg7 35.h4 a5 36.Ra7 a4 37.g4 a3 38.Ra6 Kh6 39.e4 Kg7 40.e5 Kf8 41.Kh1 Drawn.

Chapter 4: 6.Nf3.

Rantanen Salo, Finland Championship 1992

1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4 Nf6 5.Nc3 g6 6.Nf3.   The development of the knight to f3 is a common, if unambitious strategy. After Black completes the kingside fianchetto, White has many different plans. We will begin by examining some of the rarer ones, and then consider the more popular continuations. 6...Bg7.

 6...dxc4 is premature, but not terrible, for example: 7.Bxc4 Bg7 8.0-0 0-0 9.Ne5 e6 (9...Nbd7 10.Re1 Nb6 11.Bb3 Bf5 is acceptable for Black.) 10.Bg5 Nbd7 11.Qb3 Qb6 12.Qxb6 Nxb6 13.Bb3 Bd7 14.Rfd1 h6 15.Bxf6 Bxf6 16.Ne4 Bxe5 17.dxe5 Bc6 18.Nf6+ Kg7 and White was slightly better in Burchert - Krause, Dortmund 1987.


 7.Bd3 is playable, and now.

 A) 7...0-0 is the normal reply, though it makes sense to exploit the move by capturing on c4. 8.0-0 Nc6 9.Be3 (9.cxd5 Nxd5 10.Be4 Be6 11.Ne2 h6 12.Be3 Qd7 13.Qd2 Kh73. Bohnert-Gradl, Nuernberg 1989.)

 A2) 9...Bg4 is also good. 10.c5 Bxf3! followed by ...e5 is very strong for Black.

 B) 7...dxc4 8.Bxc4 0-0 9.Ne5 Nfd7 10.Bf4 Nxe5 11.Bxe5 Bxe5 12.dxe5 Qc7 is better for Black, Petr - Nun, Czech Championship 1995.

 7.Be2 dxc4 8.0-0 (8.Bxc4 transposes to the previous note on 7.Bd3 dxc4.) 8...0-0 9.Bxc4 (9.h3 a6 10.a4 Nc6 11.Bxc4 Bf5=.

 This is an unusual plan for Black in the Tarrasch Defense, but with colors reversed the extra tempo makes it worth considering..

 9...b6 10.Rc1 Bb7 11.b4.

This is a critical juncture for Black. I suspect that 11...a6 is best. Giving up the center meets with typical Tarrasch counterplay here. 11...dxc4? 12.d5! Nb8 This is the only retreat. The a5 square is not available here. 13.Bxc4 Na6 14.Nd4 Nb8 Black can't seem to make up his mind where this knight belongs. 14...Nc7 was more consistent with ...Na6, but evidently Black decided the knght is better placed on d7. 15.Nde2 All the knights in this game seem bot be a bit tipsy. Why not leave the knight in pace, since it just returens to d4 shortly. 15.Qb3 would have been stronger. 15...Nbd7 16.Bf4 a6 17.Nd4 Rc8 18.Nc6!? Bxc6 19.dxc6 Rxc6 20.Bxa6 Qa8.

 8...0-0 9.0-0 Nc6.

This is a pure Tarrasch Defense reversed. The problem, from White's point of view, is that the extra tempo does not have much of an effect, and Black can usually draw by not playing with great ambition. On the other hand, if Black does try to challnge White, the extra tempo can become more important.I have played this system for White a number of times without much success. I return to it mostly out of laziness, because I know the Black side of the Tarrasch very well. I can't recommend it on any objective grounds, however..


 10.h3 is a modest but useful move. 10...b6 (10...Re8 11.Qb3 Be6 12.Qxb7 Nxd4 13.Nxd4 Bxd4 14.Rd1 Rb8 15.Qc6 Bxc3 16.bxc3 Qc8u Hedke - Volke, Bundesliga 1991.

 10...Be6 is actually a real Tarrasch with colors reversed, since White has given back the tempo. Usually White, in the regular Tarrasch, plays 9.Bg5 cxd4 10.Nxd4 h6 11.Be3.) 11.Qa4 (11.Re1 Bb7 12.Bg5 h6 13.Be3 e6 14.Qd2 Kh7 15.Rac1 Rc8 16.Red1 = Cramling - Bellon Lopez, Terrassa 1990) 11...Bb7 12.Rd1 Rc8 13.Bd2 Qd7 14.Rac1 Rfd8 15.Qa3 Nxd4 16.Nxd4 Bxd4 17.Nxd5 Bxd5 18.Bc3 Bxc3 19.Rxc3 e6 and Black is a pawn ahead,.

Despite the missing pawn, the endgame is a litle better for Black, who can use the pawns on the d-file as targets. 19.Bd3 Bxd3+ 20.Rxd3 Nxd5 21.Nxd5 Rxd5 The further reduction in material just accentuates White's problems with the d-pawn, though the centralized king provides some compensation. 22.Nf3 Rc8 23.Rhd1 Rb5 24.b3 Bh6 25.a4 Rb4 26.Nd2 Rc2 This infiltration of the seventh rank increases Black's advanatage, which is becoming serious. 27.g3 b5 28.axb5 Rxb5 29.h4 e6 30.f4 Bf8 31.Kf3 h5 32.Nc4 Bb4 33.Ne3 Rb2 34.Nc4 Ra2 35.d5 White finally eliminates the weakling. 35...exd5 36.Rxd5 Rb8 37.Rd8+ Rxd8 38.Rxd8+ Kg7 Objectively, White has excellent drawing chances in this endgame, but some care is needwed. 39.Rd7 Kf6 40.Ra7 Ke6 41.Ke4 Re2+ 42.Kd4?! White decides to give up the g-pawn for Black's a-pawn, but the weakness of the kingside that results makes defense difficult. 42...Rg2 43.Ra6+ Ke7 44.Nxa5 Bxa5 45.Rxa5 Rxg3 46.b4 Rb3 47.Rb5 Ke6.

A general plan in this endgame is to use the king to pick off the h- and f-pawns, and then sacrifice the rook for the White b-pawn in a position where the three connnected passed paws are winning against a rook. 48.Ke4 Rh3 49.Rb6+ Ke7 50.Rb7+ Kf6 51.Rb6+ Kg7 52.b5 Rxh4 53.Rc6 Rh1 54.b6 Rb1 55.Kf3 Rb3+ 56.Kg2 Kh6 57.Rf6 Kg7 58.Rc6 h4! 59.Rd6 White has nothing better to do than shuffle the rook around. 59...Kh6 60.Rf6 Kh5! 61.Rxf7 Rxb6 This endgame is winning for Black, because the h-pawn is strong. 62.Kf3 Rb3+ 63.Ke4 h3 64.Rg7.

 64.Rh7+ Kg4 65.Rh6 Rb6 66.Kd4 Rb2 67.Rxg6+ Kxf4 68.Rf6+ Kg5 69.Rf8 h2 70.Rh8 Kf4 71.Rf8+ Kg3 72.Rg8+ Kf2 73.Rh8 Kg1 wins.

 64...Kh6 65.Rg8 Kh7 66.Ra8 h2 67.Ra1 Rh3 68.Rh1 Kh6 69.Ke5 Kh5 70.Kf6 Kg4 White resigned.

Now which way should the knight go?.

 19...Qxd5 20.Rac1 Nb6! 21.Nxa7 Qxb3 22.axb3 Rxc1 23.Rxc1 Rd8.

Black has a clear advantage in this endgame. White's extra pawn is meaningless, and the bishops of opposite color are only of limited help with roooks and knights still on the board. 24.Be4 Rd4 25.Bf3 Rd3 26.Kg2 Rxb3 27.Bxb7 Rxb2 The queenside pawns are gone, so Black will have to make do with the kingside pawn majority. 28.Be4 f5 29.Bd3 Rd2 30.Bc2 Bd4 31.Bb3+ Kg7 32.Rc2 Rd3 33.Ba2 Bf6 34.Nb5 Nd5 35.Bc4 Rd1 36.Be2 Re1 37.Bc4 Nb4 38.Re2 Rc1 39.Bb3 Nd3 40.f4 A major concession. Now White's fortress is airy. 40...Rc5! 41.Na7 and here, after time control, Black missed the simple 41...Nc1 which would have wone quickly. Nunn did prevail in the end, however. White resigned.

Chapter 6: 6.cxd5 Nxd5!?

 7...Bd7 is not as bad as its reputation.

A) 8.Bc4 This position is evaluated as clearly better for White by Varnusz, but I think that Black is just a tempo up n 7.Bc4 lines and is already slightly better. 8...Nb6! 9.Bb3 Bg7 10.Nf3 Nc6 11.Bg5 Na5 12.0-0 h6 13.Bf4 0-0 14.Bc2 Bg4 15.Be3 Nac4 16.Be4 Nd6 17.h3 Nxe4 18.Nxe4 Be6 19.Nc5 Bd5 with a strong position for Black, Willms - Wolf, Postal 1992.

 8.Qb3 Nxc3 9.Bc4 Nd5 10.Bxd5 e6 11.Bxc6+ bxc6 12.Nf3 Bg7 13.Qc4 Qb6 and Black is at least equal, Moilanen - Salo, Turku 1990.

 9.Bxc6+?! bxc6 10.Qxc6+ (10.bxc3 Qd5 = Ostermeyer - Lutz, Koln 1988) 10...Bd7 11.Qxc3 Rc8 gives Black sufficient compensation.

 16.Qxc6 loses to 16...Bxe5 - +.

 16.Nxc6 Qd7! 17.c4 Bxd4 18.Rad1 Rbc8 19.Rxd4 Qxc6 20.Qxc6 Rxc6 and Black is slightly better, though the outcomes is likely to be a draw.


 16...Bxe5 17.Rxe5 Red8 18.Bc5 (18.Re4=) 18...Rd7 19.Rae1 Rb2 20.a3 Qb7 and White has a minimal advantage at best.

 31...Qf6? 32.Bf8+!+-.

 31...Bd5 32.h5+/- (32.Re8 Qc7+ 33.Qe5+ Qxe5+ 34.Rxe5 Bb7 is not likjely to be won by White.).

 32.d5! Qf6.

 32...Qd7 33.h5 rips open the remaining barrier to the king's fortress.


 Equally effective, and prettier!.


 33...gxh5 34.Bd4 Rb6 35.Bxf6+ Rxf6 36.Qe5 is a trivial win.

 34.Bd4 Qd6+ 35.Be5 Re8.

Here Karpov provides an impressive finish. 36.Qxh6! Qxe5+ 37.Rxe5 Rxe5 38.d6 Be6 39.Qd2 Bd7 40.Qd4 Re6 41.Qa7! Time control had been reached, and Black has no reason to continue. Black resigned.

 10.Ne5 This is the most ambitious move, but there is no shortage of alternatives..

 10.a4 is very popular because it threatens to dislodge the knight from b6. Black should not over-react, however. 11...a5 is not only unnecessary, but is quite weakening..

 11.Be3 Bxb5 and White is slightly worse regardless of which piece recaptures on b5. The d-pawn remains weak, and the bishop at e3 is too passive.

This is a typical Tarrasch in reverse. The pawn at d4 is not without support, but Black can easily blockade at d5. If White does not obtain some activity, then Black can slowly organize an assault against d4. 14...Rac8.

 15.Bf3 e6!? Black ignores the attack on the pawn at b7, but White is not afraid of comlications on the b-file, and this plan proves too optimistic..

 15...Qb8 16.Re1 e6 is passive, but more solid.

 16.Bxb7 Rb8.

 24.Nc3 Rxb2 25.Nxd5 Qxd5 26.Qc3 and Black has no real compensation for the exchange.

 24...Rxb2 25.Nc4 Rb4 26.Ne5 Qb7 27.h4 This square would have been better used by the queen. 27...h5 28.a5 Kh7 29.Rac1 Bh6 30.Rc5 Rb3!.

31.f3? This wraps things up quickly, but already White was in grave danger..

 31.Nd3 Nf4 32.Nxf4 Rxg3 33.fxg3 Qb3 and Black's queen is too strong.

 31.Nf3 Nc3 (31...Rb1 32.Rf1 Rxf1+ 33.Kxf1 Qb1+ 34.Ne1 Bd2 35.Qe5 allows the stunning 35...Ne3+! 36.Qxe3 Thre is nothing better. 36...Bxe3 37.fxe3 Qe4 and Black should win.) 32.Rxc3! Rxc3 33.Ng5+ Bxg5 34.Qxc3 Bxh4 35.d5 and White retains the advantage.

This amazing move, winning the b-pawn, deserves a diagram. 23...Be6 24.Rxe6 (24.Bd6 Qd8 25.Nxb4 but the dependence of the bishop at d6 on the White queen allows Black to escape with a draw. 25...Ra8 26.Qc6 Rc8 27.Qa6 ) 24...Qxe6 25.Qxe6 Rxe6 26.Nxb4 Ne4! 27.Kf1 Nxg3+ 28.hxg3 f5 with a very complicated endgame. 23.Na4 23...c3 24.bxc3 bxc3 25.Nc5 c2 26.Rc1 Nd5 27.Nf3 Qf6 28.Qb5 Rxe1+ 29.Rxe1 Qb6 30.Qxb6 Nxb6 31.Nd3 Nd5 32.Nc1 Nc3 33.Kf1 Bf8 34.Ne5 Ba3 35.Ncd3 Bxd3+ 36.Nxd3 Nxa2.

 D2b2) 21.Rf3 21...axb5 22.Qd5 Re7! 23.Qxd6 Rd8 24.Qb6 An exchange of queens at g3 is not to White's advantae. 24...b4! 25.Qxb4 Ng5 D2b21) 26.Rf4 Nxh3+ 27.gxh3 Bxf4 28.Nxf4 (28.exf4 Rde8 29.Qc4 Re3,) RR28...Rxe3 29.Ng2 Rg3 30.Ne2 Rxg2+ 31.Kxg2 Qe4+ 32.Kf2 Re8 33.Ng3 Qe3+ 34.Kg2 Rc8 35.Qa4 Qd2+(c) Haba,P.

 D2b22) 26.Rg3 26...Ne4 D2b221) 27.Rg4!? is suggested by Ftacnik. 27...Qf2+ (27...Bxe3+?? loses to 28.Kh2+-) 28.Kh2 Nd6 29.e4 Rb7 30.Qa5 Rdb8 31.Qd5 Ne8,, 32.Ra8!? Rxb2 33.Ra7! and f7 is vulnerable.

1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4 Nf6 5.Nc3 g6 6.cxd5 Bg7 7.Bb5+!? Bd7?!.   This simple interpolation eliminates any real chance Black has of equalizing. the d7-square is needed for a knight, especially since c6 is not accessible..


 8.Qb3 Bxb5 9.Qxb5+ Qd7 10.Qxd7+ Nbxd7 11.Bf4 Nb6! 12.d6 Nh5! 13.Be5 f6 14.Bg3 Nxg3 15.hxg3 exd6 16.Nge2 Kd7 and Black is better in the endgame. The queen will come to b3 at the appropriate time, but it is too early here.

 8.d6 is interesting. 8...Bxb5 (8...exd6 9.Qe2+ Qe7 10.Bf4 Qxe2+ 11.Bxe2 d5 12.Nb5! 2 Velimirovic - Maric, Jugoslavija 1979) 9.Nxb5 Qa5+ 10.Nc3 exd6 11.Qe2+ Kd8 is not worse for Black. White has potential problems on the e-file and the king can eventually come to rest at c7 or b8.

 8...0-0 9.Qb3!.

 This is the only correct move..

 9.Nge2?! allows Black to play the powerful 9...b5!.

 A) 10.Bxb5 Bxb5 11.Nxb5 Qxd5!.

White has not fared well here..

 A1) 12.Qb3 Qxg2 13.Rg1 Qb7 14.Bf4 Nd5 (14...a6 15.Nc7 Qxb3 16.axb3 Ra7 17.Rc1 Rb7u) 15.Rc1 Nxf4 16.Nxf4 a6 and Black had a slight advantage in Kharitonov - Khaludrov, Russian-sf Arkhangelsk 1996.

 A3) 12.Nbc3 12...Qxg2 13.Rg1 Qb7 14.Qa4 (14.Qb3 Qxb3 15.axb3 Nc6 16.Bf4 Rfd8 is also clearly better for Blacck, Perman - Vatanski, Laukaa 1996.) 14...Nbd7 15.Bf4 Nd5 16.Nxd5 Qxd5 17.Qb3 Qa5+ 18.Kf1 Qa6 19.Rd1 e5! 20.dxe5 Nxe5 and Black has better attacking chances, Novak-Janata, Czechoslovakia 1981.

 C) 10.Bb3 b4 11.Na4 Bb5 12.0-0 Nxd5 and Black was better in Guido - Skembris, Genova 1989.

 D) 10.Bd3 10...b4 11.Ne4 Nxd5 12.Bg5 Nc6 13.Rc1 Rc8 14.0-0 h6 15.Bh4 Bg4 and Black has a strong position, Quinteros - Cardoso, Manila 1973.

 9.Nf3 Bg4 Black should also consider 9...b5, with strong counterplay. 10.h3 Bxf3 11.Qxf3 Ne8 (11...Nbd7 12.0-0 Nb6 13.Bb3 Qd7 14.Bf4 Rad8 15.d6 exd6 16.d5 gives White the typical advantage of more space and a more solid d-pawn, Rajcsanyi-Porubszky, Hungarian Team Championship 1994.) 12.0-0 Nd6 13.Bd3 Bxd4 14.Bh6 Bg7 (14...Re8 would have been safer.) 15.Bxg7 Kxg7 16.Qe3 Nd7 17.Rfe1 and White had pressure in the center and a lot more space in Trzaska-Konieczka, BL 1988.

 9...Qb6 10.Nf3 and here Black cannot afford to exchange queens, since the bishop at d7 makes it much harder to reclaim the pawn at d5. 10...Na6 (10...Rc8 should be tried here.) 11.0-0 (11.Bf4 Rac8 12.0-0 Qb4 13.Bxa6 Qxb3 14.axb3 bxa6 15.Rfe1 Nh5 16.Rxe7 Nxf4 17.Rxd7 Rb8 18.Rxa7 Rxb3 19.Ne5 Rxb2 20.R7xa6 Rc2 was played in Schoenweitz - Ostermeier, St.Ingbert 1991, where White should have played 21.g3 Nh3+ 22.Kg2 Nxf2 23.R1a2!) 11...Qxb3 12.Bxb3 Rfd8 13.Re1 Kf8 14.Bf4 Bf5 15.a3 Rac8 16.h3 h5 17.Ng5 Ne8 18.Rad1 Nd6 19.Be5 Bh6 20.Bf4 Bg7 21.Nf3 and Black does not have enough counterplay, Doery - Froitzheim, Wiesbaden 1990.

In this position, reached from the Accelerated Panov in the present game, Black has several choices, including the capture at d6, castling, and ...e6, and interesting move which ignores the d-pawn for now and concentrates instead on maintaining some control of d5..

 8...e6 9.Nf3 0-0.

 9...a6 10.Be2 Qb6 deserves a little more attention. 11.0-0 (11.Bf4 Nh53) 11...Qxd6 12.a4 0-0 and Black is doing fine. This plan can be reached via transposition below, too.

 This complicates matters, but objectively it was a bad idea.


 19...fxe6 20.Rf4 Qg5 21.Ne4 Be7! 22.d6 Bxe4 (22...Bxd6 23.Nxd6 Qe7 24.Rf7 Qxd6 25.Qxd6 Rxd6 26.Rxb7 Rxd4 27.Rc1+/-) 23.dxe7 Re8 24.Rxe4+/-.

 19...Rxd5! was correct..

 A) 20.Nxd5 Bxd5 (20...Qxe4?? 21.Nxf6+) 21.Rf4 Qxe6 22.Re1 Qc6u.

 B) 20.Nc7 20...Rd7.

 B1) 21.Rf4 Qh3 22.Ne4 allows the beautiful 22...Rxd4!! This was an improvement by Euwe on analysis by Sozin. 23.Qe1 (23.Nxf6+ Kh8! 24.Qxd4 Qg2#) 23...Be5 24.Rh4 Rxe4 (24...Qxh4 25.gxh4 Rxe4 26.Nxa8 Rg4+ 27.Kf1 Ba6+ 28.Qe2 Bxe2+ 29.Kxe2 Rxh4 is also winning, but more slowly.) 25.Rxe4 Bxc7 - +.

 B2) 21.Nxa8 21...Bxe4 22.Re1 Be7 is given by Euwe as winning for Black. I don't think so. 23.Qc4! Bxa8 24.Qc8+ Kg7 (24...Rd8 25.Qxf5 gxf5 26.Rxe7+/-) 25.Qxa8 Bf6 26.Qe4 Re7 (26...Qxe4 27.Rxe4 Bxd4 28.Kg2 does not give Black serious wining chances.) 27.Qxe7 Bxe7 28.Rxe7 does not look winnable to me.


 20.Rf4 Qxe6 21.Nxd5 Qxd5 22.Rxf6 Qxd4 23.Qxd4 Rxd4=+.

 20...Bxe4 21.Nxe4 Rxd8.

 21...Qxe4 22.Re1 Qxe1+ (22...Qd5 23.Re8+ Kg7 24.Qf8#) 23.Qxe1 Rxd8 24.Qe4 Rxd4 25.Qa8+ Kg7 26.Qxa7+/-.

 22.Nxf6+ Qxf6 23.Rd1 Rd5 24.Re1

 The mating theme of Re8 and Qf8 returns..

 24...h5 25.Re8+ Kh7 26.Qe7.

 26.Re4 Kg7 27.h4!? might have been more effective.

 26...Qf3 27.Qf8 Qf6 28.Qe7 Qf3 29.Rd8 Rf5 30.Qe3 Qd1+ 31.Kg2.

Black is still struggling, but now finds a way to open a path on the kingside..

 31...h4! 32.h3.

 32.gxh4 Qg4+ 33.Qg3 Qe4+ 34.Kf1 Qb1+ 35.Kg2 Qe4+=.

 32.Rd7 h3+! 33.Kxh3 Qf1+ 34.Kg4 Rxf2 35.h4 Rh2 36.Rd5 (36.Rxa7 Qf5#) 36...Rh1! and White has no defense to ...Qh3+.

 32...hxg3 33.Qxg3 Qd2?.

 Now the pendulum swings back to White. Euwe provided the following drawing line. 33...Qc1 34.Kh2 Kg7 35.Qh4 Rh5 36.Qe7 Qf4+ 37.Kg1 Rg5+ 38.Kf1 Qc1+ 39.Ke2 Qxb2+ 40.Ke3.

 34.Qh4+ Rh5 35.Qf6.

 Now the queens must come off.

 35...Qg5+ 36.Qxg5 Rxg5+ 37.Kf3 Ra5 38.a3 Rb5 39.Rd7 Kg7 40.Rxa7 Rxb2.

A tough endgame for Black, but one which does offer drawing chances to Black. Euwe conducts the remainder of the game with considerable skill and earns his half point. 41.Re7 Kf6 42.Re2 Rb3+ 43.Re3 Rb2 44.h4 Rd2 45.Ke4 Rxf2 46.Rb3 Re2+ 47.Kd5 Re6 48.Rc3 Ke7 49.Rc7+ Ke8 50.a4 g5 51.hxg5 Rg6 52.Rb7 Rxg5+ 53.Kc6 Rg6+ 54.Kc7 f5 55.d5 Rg7+ 56.Kxb6 Rxb7+ 57.Kxb7 Kd7 58.a5 f4 59.a6 f3 60.a7 f2 61.a8Q f1Q 62.Qc8+ Ke7 63.Qe6+ Kd8 64.Qd6+ Ke8 65.Qc6+ Kd8 66.Qd6+ Ke8 67.Kc7 Qf7+ 68.Kb8 Qd7 69.Qe5+ Kf8 70.d6 Kf7 Drawn.

We have already seen a number of examples of this positional factor in previous chapters. In this concrete position, Black has basically two forms of counterplay. The bishop can go to f5, and infiltrate at d3, or extend to g4 and try to undermine the support of the pawn at d5..

Again transpositions are possible into previous chapters. There are several independent lines, however. The first involves an immediate challenge to the bishop at g5, and the other uses the eventual advance of the a-pawn, which White often prevents by playing a4..

Chapter 14: 6.Qb3 Main Line with 10.Nge2

1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4 Nf6 5.Nc3 g6 6.Qb3 Bg7 7.cxd5 0-0 8.Be2 Nbd7 9.Bf3 Nb6 10.Nge2 Bf5.   This is the most popular alternative to the main lines with 10...Bg4. The play remains more complex, with ideas like ...Bd3 available to Black. On the other hand, the bishop at f3 can become a popular weapon, and White has been scoring well here..


 11.Bf4 is often played first, but both moves are essential to White's plan and transpositions are almost unavoidable..

 11.a4 is not as appropriate here..

 A) 11...a5 12.Qb5.

A1) 12...Ne8!? is playable and should be about equal. 13.Bf4 Nd6 14.Bxd6 Qxd6 15.0-0 Rfc8 16.Rfd1 Rc4! puts a lot of pressure on White's center. 17.Qb3 (17.Re1 is more accurate, as the e-file is more important than the d-file right now.) 17...Rb4 18.Qa2 Bc2 19.Rd2 Bb3 20.Qb1 Bh6 21.Rd3 Rc8 22.Ne4 Qd8 23.Nc5 Bc4 24.b3 Nxd5 25.Rd1 Bxe2 26.Bxe2 Nc3 27.Qd3 Qxd4. Durban Piera - Rogers, Las Palmas 1995.

White is much better here, but accuracy is required. (25.Ng3! exposes all of the weaknesses of the light square, and after either capture at d4, Nf5 is very powerful.) 25...f5 26.Nc3 Bxd4 27.Nb5 Bc5 28.Qb2 Ne5 29.Re1 g4 30.Bd1 g3 31.Nd4 gxf2+ 32.Kxf2 Nc4 33.Qc3 Nxd2 34.Qg3+ Kh8.

 11.Nf4 can lead to interesting play after 11...g5!?.

A) 12.Nh5 Nxh5 13.Bxh5 e6 (13...h6 is also good, since 14.h4 can be met by 14...g4 ) 14.g4 A1) 14...Bd3 15.dxe6 is complicated, but better for White. 15...Bc4 16.exf7+ Kh8 (16...Bxf7 17.Bxf7+ Rxf7 18.Be3 Bxd4 19.0 - 0! is much better for White.) 17.Qc2 Nd5 18.Be3 Nb4 19.Qd2 Nd3+ 20.Kd1 Bxd4 21.Bxd4+? (21.Bxg5 Qb6. 21.Kc2! was best, and Black would have great difficulty equalizing.) 21...Qxd4 22.Kc2 Nb4+ 23.Kc1 Qxd2+ 24.Kxd2 Rad8+ 25.Kc1 Bxf7 26.a3? (26.Bxf7 Nd3+ 27.Kc2 Rxf7 would have been only slightly worse for White.) 26...Bxh5 27.axb4 Bxg4 28.Rxa7 Rxf2 29.Nd1 Rc8+ 30.Kb1 Rd2 31.Nc3 Bf3 32.Rg1 g4 33.Ra5 Rxh2. Bonet-Codina, Postal 1988.

 B) 12.Nfe2 12...g4 13.Ng3 Bg6 14.Be2 Nfxd5 (14...Qd7 Black does not have to rush to recapture the pawn. 15.0-0 h5 16.Re1 Nbxd5 17.Bd2 e6 18.Bb5 Qd8 was fine for Black in Kindermann-Brestian, Vienna 1991.) 15.Bxg4 Bxd4 16.Nce2 Be5 17.f4 Bd6 18.f5 Bb4+ 19.Nc3 Qc8 20.0-0 Bxc3 21.bxc3 h5 22.Bf3 Bh7 23.Ba3 Ne3 24.Bxe7 Re8 25.f6 Nxf1 26.Rxf1 Qc4 27.Bd5 Qxd5.

A) 12...Qd7 13.dxe7 Rfe8 14.Qd1 Bc4 15.b3 Bxe2 16.Bxe2 Rxe7 17.Ba3 is much better for White, Pilgaard-Bauner, Denmark 1990.

 B) 12...Qxd6 13.Bxb7 B1) 13...Bc4 14.Qd1 Rad8 15.b3 Bxe2 16.Qxe2 Nbd5 17.Nxd5 Nxd5 18.Bxd5 Qxd5 19.Bb2 Qb7 (19...Bxd4 20.Bxd4 Qxd4 21.Qxe7 Rfe8 22.Qg5 Re2 gives Black some counterplay, and it seems to me that White will have difficulty winning.) 20.Qe3 Rd7 21.Rac1 Rfd8 22.Rc4 Qb6 23.g3 e5 24.dxe5 Qxe3 25.fxe3 Re8 26.Rc5 h5 27.Bd4 Re6 28.Ra5 a6 29.Rc1 f6 30.exf6 Bxf6 31.Bxf6 Rxf6 32.Rc2 Rd1+ 33.Kg2 Re1 34.Re5 Kg7 35.Rd2 Rc6 36.Kf3 Kf6 37.Red5 Re6 38.Re2 Rf1+ 39.Kg2 Rc1 40.Ra5 Rb1 41.e4 Rc1 42.Kf3 Rcc6 43.Kf4 Rc1 44.e5+ Kg7 45.Ke4 Rcc6 46.Kd5 Kf7 47.Rc5.

 B2) 13...Rad8 14.Rd1 Bc4 15.Qc2 Bxe2 16.Qxe2 is also clearly better for White, Manyai-Wozny, Zalakaros 1991.

 D) 12...exd6 13.Bxb7 Rb8 14.Bf3 D1) 14...Qd7 15.Qd1 Ba6 16.b3 (16.Re1 looks stronger, and I am not sure Black has any hope of equalizing soon.) 16...Rfe8 17.Re1 Rbc8 18.Ba3 d5 19.Qd2 Ne4 20.Bxe4 dxe4 21.Rad1 h5 22.Bc5 Kh7 23.Qf4 Qb7 24.Qg3 Nd7 25.Na4 Qc6 26.Bxa7 Bxe2. Milos-Kamsky, Palma de Mallorca 1989.

 D2) 14...Re8 15.Qd1 Ba6 16.Re1 is clearly better for White, but Black has been able to survive. 16...Rc8 (16...Qd7 17.b3 Rbc8 18.Bf4 d5 19.Rc1 Ne4 was played in Merklinger-Merkel, Germany 1993 and here 20.Bxe4 or 20.Bd2 would have provided White with a serious advantage.) 17.Ng3 Rxe1+ 18.Qxe1 Qd7 19.Bf4 Re8 20.Qd2 Re6 21.b3 d5 22.Re1 Rc6 23.Be5 Bf8 24.Nce2 and again Black is just a pawn down, though Hort-Dolmatov, Amsterdam 1980 was eventually drawn,.

 11...Qd7 has struggled against 12.a4! (12.Bg5 h6 13.Bxf6 Bxf6 14.Rad1 g5 15.h3 Nc8 16.Ng3 Nd6 17.Nxf5 Qxf5 18.Rfe1 Qg6 19.Ne4 h5 Black has a bit of counterplay, but the quality of this game degenerates quickly.

 A) 14...Qxd6 may be playable: 15.Qxd6 exd6 16.Bxb7 Rab8 17.Bf3 Rfd8 18.Ra3 (18.Re1 is more promising, and deserves practical tests.) 18...Nbd5 19.Bg5 Nxc3 20.Rxc3 Bxe2 21.Bxe2 Rxb2 22.Bf3 Rb4 23.Bc6 Rc8 24.Rcc1 h6 25.Bd2 Rb2 26.Bf4 = Wolff - Odendahl, Philadelphia W 1988.

This is the most logical move. White takes control of the d6-square..

 12.d6 is possible: 12...exd6 13.Bxb7 Rb8 14.Bf3 Nbd5 15.Qd1 and White has the extra pawn. 15...Nb4 16.Ng3 Bd3 17.Be2 Bxe2 18.Ngxe2 d5 19.b3 Re8 20.h3 Ne4 21.Na4 Rc8 22.a3 Nc6 23.Ra2 Nd6 24.Bb2 Nf5 25.Bc3 Qd6 26.Qd2 (26.g4!? might be better.) 26...Re4 27.Rb1 Rce8 and Black had the initiative. 28.Qd1 Ncxd4 29.Bxd4 Nxd4 30.Nac3 Nxe2+ 31.Nxe2 Qe6 32.Kf1 Qa6 33.Rd2 Bc3 34.Rc2 d4. Norevall - Carlqvist, Postal 1985.

 12...Bd3 13.d6!.

The return of the pawn brings several concrete positional advantage. White enjoys control of greater space and the bishops can be very useful, raking the a8-h1 and b8-h2 diagonals. I don't know why anyone would want to suffer the Black side, when the ...Bg4 lines allow White much less action. Still, it is not all that easy to win as White here..

 13...exd6 14.Qd1.

 14.Bxb7 is an error, 14...Rb8 15.Bf3 Nbd5 16.Bxd5 Rxb3 17.Bxb3 gives White rook, bishop and pawn for the queen but after 17...Re8 Black's initiative swings the balance in favor of the second player.

 14...Ba6 15.b3 h6.

 15...d5 is an instructive error. As Belyavsky points out, Black should not play this move because e5 and c5 are weakened. 16.Re1 Rc8 17.Rc1 Rc6 18.Ng3 Qd7 19.a4 Rfc8 20.Qd2 Bf8 21.Na2 Rxc1 22.Rxc1 Rxc1+ 23.Qxc1 Qc8 24.Bd2 Qxc1+ 25.Nxc1 Nc8 26.Bxa5 and White went on to win in Noskowicz-Zabczyk, Postal 1992.

 16.h3 Nh7? This move just doesn't make sense to me, and Adams returns the knight to f6 shortly. 16...Rc8 followed by ...Qd7 and ...Re8 is more in keeping with the spirit of the position..

 17.g3 Rc8 18.Bg2 Re8 19.Re1 Nf6.

 In spite of Black's waste of time White has no more than a minimal advantage. The bishop n a6 is out of play, and there is no source of counterplay for Black..

 20.Rc1 Qd7.

 20...g5 would be reasonable here.

 21.Qd2 Kh7 22.Be3.

22...d5? A positional mistake. Black is hard pressed to find a constructive plan, and is running out of waiting moves. Retreating the queen to d8 would have been stronger. 23.Nf4 Rc7 24.Nd3! The weakness of e5 and c5 is obvious, and this powerful night must be eliminated. 24...Bxd3 25.Qxd3 Rcc8 26.a4! The pawn at a5 is very weak. If Black reorganizes with ...b6, then the light squares are vulnerable, and Black has no light-squared bishop to defend them. 26...Bf8 27.Bd2 Rxe1+ 28.Rxe1 Qd8 29.Ne2 Black must now act to defend the a-pawn. 29...Na8 30.Nf4 b6 31.Qb5 Rc2 An attempt top create some counterplay in a strategically hopeless position. 32.Be3 Bb4 33.Rc1 Rxc1+ 34.Bxc1 Kg7 35.Be3 Although this is a bad bishop, it is useful in defending the d-pawn, freeing all the other White pieces for more ambitious projects. 35...Bd6 The d-pawn is lost in any case. 35...Nc7 36.Qxb6 Nd7 37.Qa7 and there is no way to trap the White queen. 36.Nxd5 Nc7 37.Nxc7 Qxc7 38.Qc6! Qe7 The endgame after the exchange of queens would have been hopeless. 39.Qxb6 Bxg3 40.Qxa5! 40.fxg3 Qxe3+ 41.Kh2 Nh5 would have let Black off the hook.40...Bd6 41.Qb5 g5 42.a5 Black resigned.

Black reacts by exchanging light-squared bishops, since the Bc8 is not destined for an active future anyway..


 10...Bf5 11.Nf4 Rc8 12.h3 g5 13.Nfe2 h6 14.g4 Bd3 15.h4+/- Polgar - Bass, New York op, 1988, , ,.

 11.Bxg4 Nxg4 12.a4.

This is the main line of the modern handling of the 5...g6 defense. White plans to advance the a-pawn and force the knight to relocate, reducing the pressure at d5. The only drawback to this plan is that the White queenside becomes somewhat loose. Aivars Gipslis has been a leading exponent of the Black side, while Sofia Polgar has been seen handling the White pieces..

 12.0-0 is the most popular alternative.


 A) 13.a4 Qd7 14.d6 Qxd6 15.a5 Nbd5 16.Nb5 Qb4 17.Qxb4 Nxb4 18.Bd2 Nfd5 19.Ra4 Nd3 20.Bc3 Rfc8 21.a6 bxa6 (21...b6 would have left White with serious problems in the endgame.) 22.Rxa6 Nxb2 23.Bxb2 Rab8 24.Nxa7 Rc2 was equal in Speck-Byrne, Australian Championship 1991.

 B) 13.Nf4 is met by 13...Qd7 and more pressure is coming on the d-file. 14.Re1 (14.Be3 Rfd8 15.d6 Qxd6 16.Rad1 e6 17.Nb5 Qb8 18.Nxa7 Qxa7 19.d5 Nfxd5 20.Nxd5 Rxd5 21.Bxb6 Qxa2 22.Qf3 Rxd1 23.Rxd1 Qxb2 24.Qxb7 Ra1 25.Qb8+ Bf8 26.Rf1 Qb1! and White resigned in Bryson-Santos, Europe 1989.) 14...Rfd8 15.Nd3 Nfxd5 16.Ne5 Qd6 17.Bd2 e6 18.Ne4 Qe7 19.Qh3 Rf8 20.Ng5 h6 21.Ngf3 h5 22.g4 hxg4 23.Nxg4 Nf6 24.Bg5 Nbd7 25.Qh4 Rfc8 was seen in Negele-Unzicker, Ingelstadt 1991, where 26.Ne5 would have won easily.

 12.Bf4 ams at an early d6. 12...Nf6 13.d6 exd6.

White has three distinct plans here, and all have had some success at the board. In the light of objective analysis, however, there is little to boast about..

 A) 14.d5 Re8 15.Be3?! This is too ambitious. Instead, 15...Qc7 or 15...Ng4 should give Black the advantage. 15...Rxe3 and it looks like Black's attack is fizzling, but after 16.fxe3 Ng4 17.Nd1 Qg5 18.e4 Re8 19.0-0 Rxe4 20.Qf3 f5 21.Nec3 Nxh2 22.Kxh2 Qh6+ 23.Kg1 Bd4+ 24.Nf2 Re3 25.Qd1 Be5 26.Nh3 Rg3 27.Ne2 and Black has more than enough compensation for the double exchange. 27...Qxh3 28.Nxg3 Qxg3 29.Rf3 Qh2+ 30.Kf2 Qh4+ 31.Ke2 (31.Kf1 Bxb2! would have maintained the balance.) 31...Qg4 32.Kf1 Bxb2 33.Rb1 Be5 34.Rc1 Qh4 35.Rh3 Qf4+ 36.Kg1 Bd4+ (36...Qe4?) 37.Kh1 Nxd5. Petersen-Rewitz, Denmark 1993. 38.Rc4 Ne3 39.Rxd4 looks at least equal for Black.

 B) 14.a4 a5 15.0-0 Re8 16.Rad1 Rc8 17.Qb5 Rc4 (17...Nc4 18.b3 Na3 19.Qxb7 Nh5 20.Bg3 Nc2 and White is better, Dolmatov-O'Cinneide, Bern 1994.) 18.Bg5 h6 19.Bxf6 Bxf6 20.b3 Rb4 21.Qxa5 Rxb3 22.Rb1 Rxb1 23.Rxb1 Nc4 24.Qd5 is solid enough for Black.

 C) 14.0-0 14...Re8 was better for White in Odendahl-Calogridis, Dallas (Pinfork) 1996. C1) 15.Ng3 Qd7 16.Rac1 Rac8 (16...h5 17.h3 h4 18.Nge2 Ne4 19.Nxe4 Rxe4 20.Be3 Rae8 21.Nc3 Rxe3 22.fxe3 Rxe3 23.Qb4! and Black is a little better, as the pawn at d5 has more support than the pawn at d4, Bednarska-Kaczorowska, Polish Women's Championship 1992.) 17.Rfd1 h5 18.Bg5 d5?.

 C2) 15.Rfe1 15...Nh5 16.a4 and White was in trouble in Moberg-Madebrink, Helsingborg 1991. 16...Nxf4 17.Nxf4 Bxd4 Black does not have to play 12...a5 immediately because the advance of the a-pawn is not a threat since Black threatens to capture the pawn at d5.

 12...Nf6 will usually transpose below after Black plays ...Nf6..

 C) 13.0-0 13...Qd6 and now White will have more possibilities after 14.Bf4 Qb4 15.Qd1!.

 C1) 15...Rfd8 16.Bc7+/- (16.d6 e5+/-) 16...Rd7 17.d6 exd6 18.Bxb6 Qxb6 19.Nd5 Qa7 (19...Qc6 20.Nef4 Nf6 21.Rc1 Qxd5 22.Nxd5 Nxd5 23.Qg4!?. 19...Qa6 20.Nec3!3) 20.Nec3+- Qxd4 21.h3 and here instead of (21.Qxd4 Bxd4 22.Nb5 Nf6+-) 21...Nh6 (21...Qxd1 22.Raxd1 Nf6 23.Nb6 Polgar - Skembris, Korfu 1990.) 22.Qxd4 Bxd4 23.Nb5 Bxb2 24.Ra2 and White wins, Black should retreat the bishop to e5 at move 24 instead, as the advance of White's f-pawn to f4 would only create a weakness. 24...Bg7 25.Nb6 Rad8 26.Nxd7 Rxd7 27.Rd1 Bf8 (27...Nf5 28.g4 Nh4 29.Rxd6!? where White can try) 28.Rad2 Nf5 29.g4 Nh4 30.Rd5 b6 31.Kh2 h6 32.Kg3 g5 33.Nxd6 Re7 34.Nf5 Re4.

I think that Black will find it hard to achieve full equality here, and certainly practical experience has not been pleasant: 35.R1d4! and the bishop comes to a3 with devastating effect:.

 C2) 15...Nf6 16.d6 was seen in Ricardi-Glavina, Salta 1987 and here 24.Qd2 or 24.Rfe1 would have left Black in a miserable position. 16...exd6 17.Nb5 led to a win for White in Swan-Williams, Postal 1992. 17...Rfd8 (17...Ne8 18.b3 d5 19.Bc1 is Laine-Ledger, Hastings 1994. By placing a rook on c1 or e1 White would have had a huge advantage. 19...Qe7 20.Ba3 Qd7 21.Rc1 Nc8 22.Bxf8 Bxf8 23.Qc2 Nb6 and Black has not been able to hold the position. Two examples: 17...Qc4 18.b3 Qc6 19.Rc1 Qe4 20.Bxd6. Kiefhaber-Schaack, Germany 1990. 17...Nc8 18.b3 d5 19.Bc1 Qe7 20.Ba3 Qe4 21.Bxf8 Bxf8. Carlier-Sibbing, Netherlands 1985.) 18.b3 Ne4 19.f3 g5 20.fxe4 gxf4 21.Nxf4 d5 22.e5 and White is better, Oral - Nikolaidis, EU-Cup Olomouc 1996. 22...Nc8 (22...Qe7 23.Nh5 Kh8 24.Nxg7 Kxg7 25.Nd6 Rxd6 26.exd6 Qxd6 27.Qh5 Rf8 28.Rf3 Nd7 29.Qg4+ Kh8 30.Rg3 Qf6 31.Rf1.

This is the main line. The immediate advance of the a-pawn is one of the popular alternatives.) 23.Nc7 Ra7 24.Ncxd5 Qf8 25.Qg4 Kh8 26.Ne6 gives Black an initiative.


 12...Qd7 13.a5 Nc8 14.Bf4 Nf6 15.0-0 Rd8 16.Rfc1 Nd6 17.Bxd6 Qxd6 18.Qxb7 puts enough pressure on c3 to make up for the pawn.

 13.Nf4 was agreed drawn in Winsnes-Gipslis, Berlin 1991..

 13.a5 Nbxd5 14.Qxb7 Qd6 15.Qb3 Rab8 was about equal in Winterstein-Jonitz, Giessen 1991. 16.Qd1 Rfc8 (16...e5 17.0-0 Rfd8 18.dxe5 Qxe5 19.Qd4 Qxd4 20.Nxd4 Nxc3 21.bxc3 Rbc8.

Although Black is a pawn down, I'd rather be sitting on that side of the board. The pressure at d5 is intense, and the long diagonal can be used by Black. 22.a6 Ne4 23.Nb5 Nxc3 24.Nxc3 Bxc3 25.Ra2 Bd4 26.g3 h5 27.Kg2 Rc6 28.Rd1 Bb6 29.Re1 Rdc8 30.Be3 Re8 31.Bxb6 Rxe1 32.Bxa7 Ree6 33.Bb6 Rxb6 34.a7 Ra6 35.a8Q+ Rxa8 36.Rxa8+ Kg7 37.h4? Wrong knight. After 27...Nbd5 Black would have all the chances.) 17.0-0 Rc6 (17...e6 18.Re1 Qa6 19.Ra4 h6 20.h3 Rb7 21.Nxd5 Nxd5 22.Ng3 Qb5 23.Ne4 Rc6 24.Nc5 Rbc7! and White went on to win in Polgar - Arkell, London 1988.) 18.h3 Ra6 19.Qd3 Nb4 20.Qf3 Qc6 21.Qxc6 Nxc6 22.d5 Nb4 23.Rd1 Rd8 24.Bg5 Rad6 is not so effective here. After 25.Bf4 R6d7 26.d6 e6 27.Na4 Nfd5 Black plays 28.Bg3 Rb7 29.Nec3 Nxc3 30.bxc3 Nc6 31.a6!.

 13.d6! with a good game, for example 13...Qxd6 14.Bf4 Qd7 15.Be5 Rac8 16.0-0 Rfd8 17.Rfd1. Karacsony-Lepsenyi, Budapest 1995. 17...Nfd5.

Black does not have to play this move, but it is a good idea. 18.Bxg7 Kxg7 19.Ne4 Qg4 is not solid enough after 20.f3 Qe6 21.Qd3 Nc4 22.Nc5 Qe3+ 23.Qxe3 Ncxe3 24.Nxb7 Nxd1 25.Nxd8 N5e3 26.Nb7 Rc2 27.Nf4 g5 28.Nd3 Rxg2+ 29.Kh1 Rd2 30.Nbc5 Nc2 31.Rc1 Nxd4 32.Ne1 Nf2+!.

Black's formation is quite solid and the extra doubled d-pawn is of little significance. White usualy gives it up before long by advancing to d6, returning the material for positional considerations. 25...Rc5 26.Qe6 exd6 27.Qxf5 dxe5 28.Ne4 Rxa5 29.Bg5 Qb6 30.Rxa5 Qxa5 31.Rc1 Qb4 32.h4 Rf8 33.Rc7 Qb6 34.Nf6+ Bxf6 35.Bxf6 Qb4 36.Rc8 This is the only move for White which can cause Black any problems.

This is the correct rook to place at c8. The pawn at a5 remains defended, and White has no way to make progress. In the long run, the superiority of the bishop at g7 over White's dark-squared bishop becomes apparent.) 25...Nxa4 26.Nd3! Qb3 27.Nc5 Nxc3 28.Rxc3 Qa2 29.Bg5 Nd7 30.Nxd7 Rxc3 31.Qe8 Black has a small but persistent advantage. Both minor pieces are better placed and the c-file is controlled by the heavy artillery.


Black removes one pair of queenside pawns to create a target on the queenside. 18.Qd3 Ne8 19.Ra2 Nc4 20.b3 Ne5 21.Qd1 Nc7!? Now the d-pawns are removed, eliminating White's spatial advantage. 22.Nxc7 Rxc7! 23.Ba3 b5.

Black now has the advantage of bishop against knght. 24.axb5 Rb7 25.Ne2 Qxb5 26.Nc1 Nd7 Black can easily cope with White's threats. 27.Bxd6 Nb6 28.Bf4 Nxd5 29.Bd2 Nc3? On the last move of time control, White chooses to weaken the position. 30.Bxc3 Bxc3 would have been less commital. 31.Qf3 Rc8 32.Rc2 Rbc7 33.Rd1 Kg7 34.h3 Bf6 35.Rxc7 Rxc7 36.Ne2 h5 37.Rd6 Qe5! This is no time for an endgame. The queen has work to do! 38.Rd5 Qa1+ 39.Kh2 h4 40.g3?! 40.Qg4 would have offered considerably more resistance and it is not clear that Black has enough to win. 40...Qf1 41.Rd2 Be5 42.Qg2 Qe1!.

43.Ra2 Re7 44.Qg1 Qb4 45.Qd1 Qe4 46.Rd2 Rb7 47.Rd3 a4 48.Re3 Qf5 49.f4 Bf6 50.bxa4 Rb2 51.Qd6 Qb1 52.Qd5 Qe1 White resigned.

1.e4 c6 2.d4 d5 3.exd5 cxd5 4.c4 Nf6 5.Nc3 g6 6.Qb3 Bg7 7.cxd5 0-0 8.Be2 Nbd7 9.Bf3 Nb6 10.Nge2.   In this game we examine alternatives to the main lines which involve the early development of the bishop to g4 or f5..


 10...Ne8 11.0-0 Bf5 12.Re1 Rc8 13.Bf4 Nd6 14.Rac1 looks to be only marginally better for White.

 10...h6 11.0-0 g5 12.h3 Qd6 13.Bd2 a6 14.Ng3 a5 15.a4 Qb4 16.Qc2 Nc4 17.Bc1 Nd6 18.Re1 Re8 19.Bd2 (19.b3!? Qxd4 20.Be3 Qb4 21.Bd2 Qh4 22.Nb5 Nxb5 23.axb5 might give White some advantage.) 19...Qxd4 20.b3 Qc5 was equal in Troltenier-Fuchs, Germany 1988.


 11.a4 is an obvious reply. Black can transpose to the main lines with either ...Bf5 or ...Bg4, but there are some independent paths. 11...Qd6 is the most interesting.

A) 12.0-0 Qb4 (12...Bf5 13.Nb5 Qd7 14.Nbc3 Ra6 15.d6 exd6 16.Nf4 Bg4 17.Bxg4 Nxg4 18.h3 Nf6 19.Be3 Rc8 20.Rfc1 Rc4 21.Ncd5 Rxc1+ 22.Rxc1 Nfxd5 23.Nxd5 Nxd5 24.Qxd5 h6 25.Rc5 Rb6 26.Rxa5 Rxb2 27.Ra8+ Kh7 28.a5 Rb5 29.Qa2 Qf5 30.a6 bxa6 31.Rxa6 d5 32.Ra7 Rb4 33.Ra5 Bxd4 34.Rxd5 Rb1+ 35.Kh2 Be5+ 36.g3 Qe4 37.Qxb1 Bxg3+ 38.fxg3 Qxb1 39.Rd2 Qe1 40.Bf4 g5. Barendse - Dorenberg, Enschede 1992) 13.Qa2 Rd8 14.b3 Qd6 15.Nb5 Qd7 16.Nec3 Qf5 17.Ba3 Bf8 18.Rfe1 Qf4 19.Bc1 Qb8 20.g3 Ne8 21.Bf4 Nd6 22.Nxd6 exd6 23.Bg5 Rd7 24.Re8 f6 25.Bh6 Rf7 26.Nb5 Nd7. Metz - Steinmacher, Waldshut 1991.

 B) 12.Nb5 12...Qb4+ 13.Qxb4 axb4 14.d6 exd6 is a bit better for White. 15.b3 (15.Nxd6 Rxa4 16.Rxa4 Nxa4 17.0-0 Be6 18.Nf4 Rd8 19.Nxb7 Rxd4 20.Nxe6 fxe6 and Black was able to draw in Behling-Derikum, Germany 1984.) 15...Be6 16.Nc7 Rab8 17.Nxe6 fxe6 18.Bd2 Nbd5 19.0-0 Kf7 20.Rfc1 Rfc8 21.g4 Nc3 22.Nxc3 bxc3 23.Rxc3 Rxc3 24.Bxc3 and White went on to win in Dolmatov-Halldorsson, Reykjavik 1988.

 11.Bf4 is one of two moves that invite the advance of Black's a-pawn, 11...a4 12.Qb5.

 A) 12...Bf5 13.h3 Ne8 14.g4 Bd7 15.Qd3 Nd6 16.h4 Qc8 (16...Nbc4!? comes into consideration.) 17.Rc1 Bxg4 18.Nxa4 Qf5 19.Qxf5 Nxf5 20.Bxg4 Nxa4 21.Bxf5 gxf5 22.Rg1 and White had an attack on the kingside, Drugda-Cech, Postal 1992.

 B) 12...Bg4 is quite playable here, leading to positions similar to that of the Main Lines with ...Bg4.

 C) 12...Bd7 13.Qb4 Bg4 14.Bxg4 Nxg4 15.d6 e5 16.dxe5 Nxe5.

This is an interesting position. Black has some potential compensation along the a1 - h8 diagonal, and the pawn at d6 is very weak. So it seems White should bring a rook to d1, either directly or by castlng queenside. The latter seems far too risky to me, as the king will come under a ferocious attack. So I think that 17.Rd1 is best, but that move has yet to be tested..

 C1) 17.0-0 Nd3 18.Qe4 Nxf4 19.Qxf4 Re8 20.Rad1 Be5 21.Qb4 Re6 22.Nb5 Rc8 23.f4 Rc4 24.Qd2 Bg7 25.Rf3 (25.Nec3 would create real problems for Black. White will advance the f-pawn and undermine Black's kingside pawn stucture.) 25...Rce4 26.Nec3 Nc4 27.Qf2 Ne3 28.Rc1 Ng4 29.Qc5 This loses by force. (29.Qg3 would have maintained control of the e1 - square and Black would have nothing better than 29...Qb6+ 30.Kh1 Bxc3 31.Nxc3 Qxb2 and after 32.Rg1 Black has problems with the knight at g4 and pawn at d6.) 29...Re1+ 30.Rxe1 Rxe1+ 31.Rf1 Qh4 32.h3 Ne3 33.Rxe1 Qxe1+. Rota-Gagliardi, Postal 1985.

 C2) 17.Bxe5 17...Bxe5 18.Rd1 Rc8 19.Nd5 Nxd5 20.Rxd5 Qg5 21.Qe4 Rce8 22.d7 Re6 23.Qd3 Rd8 24.0-0 Qe7 25.Rd1 Bxb2 26.Ng3 Ba3 27.Rd4 Re1+ 28.Rxe1 Qxe1+ 29.Nf1 Bc5 30.Qe4 was drawn in Jensen-Du Jardin, Denmark 1984.

 11.Bg5 also allows the effective advance of the a-pawn. 11...a4 12.Qb5 Bd7 13.Qb4 Bf5 14.0-0 Nfxd5 (14...Rc8 is also sensible.) 15.Nxd5 Nxd5 16.Qxb7 Be6 17.Nf4 Nxf4 18.Bxf4 Qxd4 19.Be3 Qxb2 20.Qxe7 and Black was at least equal, Berg-Derikum, Germany 1985.


 11...Qd6 12.Bf4 Qb4 13.Rfe1 Nc4 14.Na4 Nd2 15.Bxd2 Qxd2 16.Nb6 gave White a clear advantage in Sadilkova-Skacelova Zahorovska, Frenstat 1989.
