1. e4 e6 2. d4 d5 3. Nc3 Bb4 4. e5 c5 5. a3 Bxc3+ 6. bxc3 Ne7 7. h4. One of the sharpest lines against the Winawer French besides 7. Qg4.
7. ... Qc7. After 7. ... Nbc6 8. h5 h6 9. Qg4 Rg8 10. Bd3 white is better, as played already in 1937 in the game L. Steiner – Koshnitzky.
8. Nf3. The Pawn sacrifice 8. h5 cxd4 9. cxd4 Qc3+ 10. Bd2 Qxd4 11. Nf3 Qe4+ 12. Be2 Nf5 is not entirely clear.
8. ... Nbc6 9. h5 h6 10. Bd3 Bd7. Avoiding a trap: 10. ... cxd4 11. cxd4 Nxd4? 12. Nxd4 Qc3+ 13. Qd2! Qxa1 14. c3 Nc6 15. Nb3 winning the Black Queen.
11. 0-0 0-0-0. 11. ... c4 12. Be2 f6 was played before.
12. a4 Nf5. Black should have either attacked the center with 12. ... f6 or blocked it with 12. ... f5.
13. Ba3 f6?! Too late, but after either 13. ... cxd4 14. Bxf5 exf5 15. Bd6 Qb6 16. cxd4 or 13. ... c4 14. Bxf5 exf5 15. a5 Be6 16. Bd6 Qd7 17. a6 White is better.

16. Bd4. Consolidating, but 侯 (Hóu) could have played the sharp 16. Bb4!? Nxb4 17. cxb4 Qxb4 18. Bxf5 exf5 19. Nd4 Rhe8 20. Re1 Be6 21. Rb1 with a powerful attack.
16. ... g6? Trying to open files against the White King, Black makes a fatal mistake. 16. ... Rhf8 is better.
17. hxg6 Rhg8. After 17. ... Nce7 18. Nd2 Nxg6 19. Nb3 Qc7 20. Bxf5 exf5 21. e6 Bxe6 22. Bxh8 White should win.
18. Bxf5! exf5 19. Nh4 Ne7. 19. ... Be8 is met by 20. Qh5!.


20. e6! White opens the e-file and preserves the g-Pawn.

29. Re2? The wrong Rook. Both 29. Ra2 and 29. e5 would allow White to maintain her position. 29. ... Nb5! 30. Nxb5? Not a good move, but it’s hard to give a good advice: 30. Rxa6?? Nxc3 loses right off, while on other moves Black can play ... Nb5-d4. 30. ... Qxb5 31. Rae1 Rxb2 32. Rxb2 Qxb2 33. Bxd6 Qb4. That’s the point! Black wins at least a Pawn, remaining with a won ending.


34. Rd1. 34. f3?? is unplayable because of 34. ... Rxd6! winning on the spot, while after 34. Rf1 Qxe4 35. Bxc5 Qxd5 36. Qa3 Qc6 Black’s passed a-Pawn would make the difference. 34. ...

Qf4! seems fine for Black.

White wishes to avoid theory, but her play is somewhat passive, and Alexandra Konstantinovna will not meet any difficulties. 10. ... Na5 11. Bc2 c5 12. h3 Bd7 13. d4 Qc7 14. d5. 侯逸凡 (Hóu Yìfán) closes the centre, which in the present situation is to her opponent’s advantage. The sharper 14. b4 was worth considering here. 14. ... c4 15. Nbd2 Nb7 16. Nf1 Nc5


17. g4. Having no prospects on the Queenside, White launches herself toward the Kingside. But the black squares on the Kingside are now seriously weakened — which will eventually affect the result. 17. ... h5 18. N3h2 hxg4 19. hxg4 Qc8 20. f3 Nh7 21. Ng3 Bg5 22. Nf5.

Kosteniuk stands clearly better, but seemingly White can still resist... 29. ... Rag8 30. Raf1 Qf4 31. Rxh8 Rxh8 32. Rh1 Rxh1 33. Nxh1.


Apparently the Chinese woman has defended all her weaknesses, but here Alexandra Konstantinovna, taking advantage of the vulnerability of the f3-Pawn, delivers a terrible blow. 33. ... Nd3! The Knight enters with decisive effect 34. Bxd3. White must take it — the b2-Pawn is attacked, and there is the threat of ... Ng5xf3 followed by a fork on e1. 34. ... cxd3 35. Qf2 d2 36. Ng3


36. ... Nxf3! The fulfillment of a beautiful combination. 37. Qxf3 Bxg4! 38. Qf2. After 38. Qxf4 exf4 White can resign at once. 38. ... d1=Q 39. Nxd1 Bxd1 40. Qe1 Bf3+ 41. Kg1 f5 42. exf5 gxf5. Black has an extra Pawn and an overwhelming position. The rest is simple. 43. Qf2 Kg6 44. b3 e4 45. c4 bxc4 46. bxc4 Qg5 47. c5 f4 48. cxd6 fxg3 0 : 1.

Women’s World Chess Championship Knockout Tournament; match game 2; Nalchik, September 5, 2008
Sicilian Defence B53

Notes by International Master Elena Sedina, Torre & Cavallo Scacco!, No. 11, November 2008, pp. 15-16.

1. e4 c5 2. Nf3 d6 3. d4. I think my opponent was already a bit surprised by my 3rd move, as in the last years I have always played here 3. Bb5+. 3. ... cxd4 4. Qxd4!? A line especially (and successfully) played by Sergio Mariotti in the 1970s, which was recently reintroduced at high level by super Grandmaster Gata Kamsky. I had prepared it, together with Grandmaster Arthur Kogan, especially for my first round opponent, Irina Krush of United States. [...] Irina then did not take part in the tournament, but my careful preparation proved not to have been in vain... 4. ... Nc6. In the first tie-break game the young Chinese preferred 4. ... a6 [...]. 5. Bb5 Nf6. Here is a brilliant win by the young Chinese prodigy from the World Championship under-20 which was held a little time before than the Women’s World Championship: 5. ... Bd7 6. Bxc6 Bxc6 7. Nc3 h6 8. Be3 e5 9. Qc4 Nf6 10. 0-0-0 Qc8 11. Qd3 a6 12. Nh4! b5 13. f4 b4 14. fxe5 dxe5 15. Nd5 Bb5 16. Qd2 Qc6 17. Nf3! Nd7 18. Nxb4 Qc4 19. Nd5 Qxa2 20. Nc7+ Kd8 21. Qc3! Qa1+ 22. Kd2 Qa4 23. Nd5 Rc8 24. Bb6+ Nxb6 25. Nxb6 1 : 0 侯逸凡 (Hóu Yìfán) – Arun Prasad, 47th World Junior Chess Championship U-20, Gaziantep 2008. 6. Nc3 Bd7 7. Bxc6 bxc6? It’s a trivial and rather unexpected mistake, especially because it was committed by a player who has already achieved all the Grandmaster norms. The theoretical (and logic) move is certainly 7. ... Bxc6. Probably 侯逸凡 (Hóu Yìfán), who occasionally plays this variation as White, had her reasons to avoid the main line... 8. e5 dxe5 9. Nxe5 e6. On 9. ... Qb6 White would play 10. Qc4 provoking the advance 10. ... e6 anyway. 10. 0-0 Be7 11. Rd1. The outcome of the opening is not satisfactory for Black: in addition to her spoiled Pawn structure, she is also behind in development. 11. ... Qb6 12. Qc4. A valid alternative could be 12. Qd3!? with the idea of Qd3-g3. 12. ... Rd8 13. Bg5 h6. 13. ... Qxb2 loses quickly due to 14. Rab1 Qa3 (or 14. ... Qxc2 15. Nxd7 Nxd7 16. Bxc7 Kxc7 17. Nd5+) 15. Bxf6 Bxf6 16. Nxd7 Bxc3 17. Qxc6 Ke7 18. Rb3 winning in both cases. 14. Be3! After the more obvious 14. Nxd7?! Nxd7 15. Bxe7 Kxe7 16. Ne4 Nf6 17. Nxf6 Kxf6 it would not have been easy to exploit the exposed position of the Black King. The key idea of the Bishop move is to transfer it to c5 trying to exchange Black’s dark-square Bishop and preventing her from castling. 14. ... Qc7. Also after 14. ... Qxb2 15. Rab1 Qxc2 the winning idea is always the same: 16. Bc5! Nd5 (after 16. ... Bxc5 17. Qxc5 Black cannot defend against White’ numerous threats) 17. Bxe7 Qxc3 18. Qxc3 Nxc3 19. Bxd8 Nxd1 20. Rxd1 and finally White remains a piece ahead. 15. Nxd7 Rxd7. On 15. ... Nxd7 there would follow 16. Nb5. 16. Rxd7 Qxd7 17. Rd1


17. ... Nd5? After this move Black ends up in a desperate position. The best try for counterplay would have been 17. ... Qb7 18. Bc5 0-0! 19. Bxe7 Qxe7 20. Qxc6 Qb4 and White must work very hard to convert her extra Pawn. 18. Bc5 Qb7. Now la variante di prima 18. ... 0-0 19. Bxe7 Qxe7 20. Qxc6 is certainly favourable to White. 19. Nxd5 exd5?! Black’s decision to stay with the King in the centre is hard to understand. The variation 19. ... cxd5 was certainly to be preferred, even though after 20. Qa4+ Qd7 21. Qb4! (the ending after 21. Qxa7 Qxa7 22. Bxa7 Kd7 23. c4 is almost impossible to win) 21. ... a5 22. Qa3 Qc7 23. Bxe7 Qxe7 24. Qa4+ Qd7 25. Qxa5 0-0 26. c4 and White should manage to convert an extra Pawn. 20. Qe2 Kd8 21. Bd4! At this stage, exchanges definitely favour Black. 21. ... Re8 22. Re1! Keeping the Black pieces tied up is more important than immediate material gain. After 22. Bxg7?! Bg5 23. Qf3 Qe7 White would allow Black to recoordinate her forces. 22. ... f6 23. Qe3 Qc7


24. b4! Preventing Black from continuing ... c6-c5. For this reason the move 24. Bxa7?! would not be so good after 24. ... c5. 24. ... f5 25. Bxg7. The time of the harvest has finally come: the end is very near for Black. The rest of the game is of little interest. 25. ... Rg8 26. Be5 Qb7 27. Qxh6 Qxb4 28. c3 Qg4 29. Bg3 Rg6 30. Qh8+ Kd7 31. Qb8 Qg5 32. Qc7+ Ke8 33. h4 Qf6 34. h5 Rg4 35. Bd6 Re4 36. Qxc6+ Kf8 37. Bxe7+ Qxe7 38. Rxe4 Qxe4 39. Qa8+ Ke7 40. Qxa7+ Kd6 41. Qd4 Qb1+ 42. Kh2 Ke6 43. h6 Qb7 44. Qg7 Qb8+ 45. g3 Qb2 46. Kg2 1 : 0. In conclusion, although, after all, this win was not enough to allow me go through the round, it will remain as one of the highest achievements of my career. Now, after overcoming the bitterness of the lost tie-breaker, I thought that in any case being eliminated in the eighth-finals extra time by the World Championship finalist was not such a little thing...

At First Bite

侯逸凡 (Hóu Yìfán) – Alexandra Konstantinovna Kosteniuk
Women’s World Chess Championship Knockout Tournament; Final match game 1; Nalchik, September 14, 2008
Spanish Game C90

Notes by Alexandra Konstantinovna Kosteniuk, Chess Life Online, December 8, 2008.

The first game of any match is very important. If the match is short it’s even more important since a good start means a lot. I was very happy to begin the match (for the first time in the championship) with the black pieces.

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. 0-0 Be7 6. Re1 b5 7. Bb3 0-0 8. a3


An unexpected move. I was not ready for this variation. I thought she would opt for a different kind of Anti-Marshall starting with 8. a4. 8. ... d6. Since I didn’t know much about this kind of variation, I tried to use my logic in order to solve the opening problems. Magnus Carlsen used this variation twice with White this year and had pretty good results with it, although I doubt it was purely a question of the opening. Those two games went:
a) 8. ... Bc5 9. c3 d6 10. d4 Bb6 11. h3 Re8 12. Bg5 h6 13. Bh4 exd4 14. cxd4 g5 15. Bg3 g4 16. hxg4 Bxg4 17. Bh4 Nxd4 18. Nc3 Bxf3 19. gxf3 Kh8 20. Nd5 Rg8+ 21. Kf1 Ng4 22. Qxd4+ Bxd4 23. Bxd8 Nh2+ 24. Ke2 Raxd8 25. Rad1 Bxb2 26. Rh1 c6 27. Nf4 Be5 28. Nd3 Nxf3 29. Kxf3 Bg7 30. Rh5 d5 31. exd5 Rd6 32. Rf5 cxd5 33. Rc1 Rf6 34. Rxf6 Bxf6 35. Rc6 Kg7 36. Nf4 Bg5 37. Nh5+ Kh8 38. Rxa6 d4 39. Ke4 Rg6 40. Ra7 1 : 0 Carlsen – Aronian, 25th Torneo Internacional de Ajedrez Ciudad de Linares – Morelia, Morelia 2008;
b) 8. ... Bc5 9. c3 d6 10. h3 Bb6 11. d3 h6 12. Nbd2 Ne7 13. Nf1 Ng6 14. Ng3 Bb7 15. Nf5 Bc8 16. d4 Be6 17. dxe5 Bxb3 18. Qxb3 dxe5 19. Qc2 Re8 20. c4 bxc4 21. Qxc4 Qd7 22. Be3 Qe6 23. Qxe6 Rxe6 24. g3 Rb8 25. Bd2 Nf8 26. Bc3 N8d7 27. Re2 Rbe8 28. Nd2 Nc5 29. Kg2 Na4 30. Rc1 Rc6 31. Ne3 Nxc3 32. Rxc3 Rxc3 33. bxc3 Ba5 34. Nd1 Rd8 35. Nc4 Rxd1 36. Nxa5 Rd3 37. Nc4 Rxc3 38. Nxe5 Rxa3 39. f3 Ra5 40. Nc6 Rc5 41. Nd4 a5 42. Ra2 Rc4 43. Nf5 a4 44. Ne3 Rc3 45. Kf2 a3 46. Nc2 Nd7 47. Nxa3 Ne5 48. f4 Nd3+ 49. Kg2 Nb4 50. Rb2 c5 51. Nb5 Rd3 52. e5 g5 53. fxg5 hxg5 54. Nd6 Re3 ½ : ½ Carlsen – Lékó, 17th Amber Blindfold Chess Tournament, Nice 2008.
9. c3 Bg4. During the game I was interested in transposing to a Marshall by playing ... d6-d5. Would the s2-a3 move be helpful for White? Since I couldn’t understand the difference between a normal Marshall and a Marshall with a2-a3 I finally decided not to play ... d6-d5. After the game I found a game between Suetin and Lilienthal where Andor played 9. ... d5 10. exd5 Nxd5 11. Nxe5 Nxe5 12. Rxe5 c6 13. d4 Bd6 14. Re1 Qh4 15. g3 Qh3 16. Be3 Bg4 17. Qd3 Rae8 18. Nd2 Re6 and even though here Suetin played using the fact that the Pawn is on a3, 19. c4 (19. a4 would lead to a very well-known theoretical position of the main Marshall variation) Black could have played 19. ... Bf4! (19. ... bxc4 20. Nxc4 Rb8 21. Bc2 Nxe3 22. Nxe3 Bf3 23. Qf5 Qxf5 24. Bxf5 Rf6 25. b4 Bf8 26. Bd3 Rd8 27. Nc2 Ra8 28. Re5 Bd5 29. Rae1 Rd6 30. Be4 Be6 31. Rd1 Be7 32. Rc5 1 : 0 Suetin – Lilienthal, Kislovodsk 1967. 10. d3 Na5 11. Bc2. I was a little bit surprised to see this move. I thought that the Bishop would go to a2. 11. ... c5 12. h3 Bd7! 13. d4 Qc7 14. d5. After this move we have a Classical Chigorin with the strange move a2-a3 and an extra tempo for Black. Since I play this kind of structure for White I knew the basic ideas and plans for both sides and that gave me a practical advantage. 14. ... c4 15. Nbd2 Nb7 16. Nf1 Nc5 17. g4?!


A very risky move. Keres was the first to use this move in the position with the Pawn on a2 and the Knight on b7. I knew this idea since not so long ago, in a blitz game I unsuccesfuly tried to use this plan for White. I would suggest a normal move such as 17. Ng3 or 17. N3h2 for White. 17. ... h5! Of course Black didn’t want to allow White to put her Knight on g3. 18. N3h2? Here White shouldn’t allow Black to close the g-file. 侯 (Hóu) should have played 18. gxh5 Bxh3 and only here 19. N3h2 hoping to use an open g-file for the attack. 18. ... hxg4 19. hxg4 Qc8. Forcing White to weaken the black squares. 20. f3 Nh7 21. Ng3 Bg5 22. Nf5!? An interesting idea, but only if 侯 (Hóu) finds the most brave continuation. 22. ... Qd8 23. Kg2 g6 24. Ng3. After this move, Black’s advantage is unquestionable. White should have tried to complicate the game with 24. Nxd6!? Bxc1 25. Qxc1 Qf6 26. Nf5 gxf5 27. gxf5 Qg5+ 28. Ng4 and despite the extra piece, Black has to be very careful. For example after 28. ... Qxc1 29. Raxc1 f6 30. Rh1 Kg7 31. Rcg1 White has very strong compensation for the Knight. 24. ... Kg7 25. Rh1 Rh8 26. Nhf1 Qf6 27. Be3 Bxe3 28. Nxe3 Ng5 29. Qe2 Rag8?! I didn’t see how to continue and decided simply to wait. I think I should have played 29. ... Nd3!? 30. Bxd3 cxd3 31. Qf2 Qf4 32. Rad1 and it seems that the d3-Pawn will be lost in a few more moves. But it’s not that easy: 32. ... a5 33. Rxd3 [33. Rxh8 Rxh8 34. Rxd3 (34. Nef1 Qf6! preparing the f4 square for the Knight 35. Rxd3 Nh3 36. Qe3 Nf4+ 37. Kg1 Nxd3 38. Qxd3 Qf4 and Black should be winning soon) 34. ... Nxe4! 35. fxe4 Rh2+) 33. ... Rxh1 34. Nxh1 (34. Kxh1? Nh3!) 34. ... Nxe4 35. Qe2 Rh8 with attack. 30. Raf1 Qf4 31. Rxh8? 侯 (Hóu) couldn’t handle the pressure and decided to exchange the Rooks forgetting about a very strong resource that Black will have after this exchange. She should have continued the game by playing 31. Qf2 and I’m not sure what I would have played. During the game I was thinking about playing on the Queenside. Although Black’s position is better, it is unclear how to get something concrete from this small advantage. 31. ... Rxh8 32. Rh1 Rxh1 33. Nxh1 Nd3!


After this move the White’s position collapses like a house of cards. 34. Bxd3. After 34. Ng3 Black would continue 34. ... Nxf3 35. Bxd3 Nh4+ 36. Kh3 cxd3 37. Qxd3 Nf3 dominating the game. 34. ... cxd3 35. Qf2 d2 36. Ng3 Nxf3! Of course not 36. ... Qxe3 37. Qxe3 d1=Q 38. Qxg5 giving White some initiative. 37. Qxf3 Bxg4! After this move the game is practically over and I was precise till the very end. 38. Qf2 d1=Q 39. Nxd1 Bxd1 40. Qe1 Bf3+ 41. Kg1 f5 42. exf5 gxf5 43. Qf2 Kg6 44. b3 e4 45. c4 bxc4 46. bxc4 Qg5 47. c5 f4 48. cxd6


48. ... fxg3. The last precise moment. It was still possible to lose the game: 48. ... Qxg3+?? 49. Qxg3+ fxg3 50. d7. 0 : 1.

Se nella modalità classica gli “Scacchi Matti” à la Paolo Bagnoli sono ormai un cult alla quinta recidiva, negli scacchi960 la casistica suicida-cappellologica è ancora alla preistoria, anche se... per mole e prole gli scacchi cangianti sono il Paese dei Balocchi!

Lékó ricorda Fischer

Intervistato da Janis Nisii all’indomani del successo allo Sparkassen Chess Meeting di Dortmund (Torre & Cavallo Scacco!, n. 9, settembre 2008, pp. 3-6 e p. 30), il Grande Maestro ungherese Péter Lékó, già enfant terrible degli scacchi negli anni ’90, ha ricordato le sue ormai remote frequentazioni con Bobby Fischer:
– Mi puoi parlare delle tue lezioni con Fischer?
– Non ho mai fatto lezioni con Fischer, questa cosa che si dice è frutto di un fraintendimento. No, ho avuto una relazione molto stretta con lui negli ultimi anni in cui ha vissuto in Ungheria. Ci siamo avvicinati molto e siamo diventati amici, ma non credo sia bello parlare di questa amicizia proprio perché era così forte.
– C’era una grossa differenza di età...
– Sì, ma è stato splendido. Abbiamo passato dei momenti magnifici insieme tra il 1998 e il 1999.
– Quindi non prendevi lezioni da lui. Però parlavate di scacchi, immagino, puoi dirci qualcosa?
– No, non prendevo lezioni da lui innanzitutto perché lui non ne dava proprio di lezioni! Ma per me è stato veramente incredibile conoscere la sua visione degli scacchi. Anche se non era tra i top da più di 20 anni, era sorprendente il modo in cui parlava del gioco. Il modo in cui pensa e vede gli scacchi è assolutamente fenomenale [qui, e in altre frasi successive, Peter usa i verbi al presente, come se Fischer fosse ancora vivo... N.d.R.]. Era facile comprendere perché fosse il numero uno in assoluto e perché è diventato una simile leggenda, cosa che prima di incontrarlo non capivo. Credo che la generazione più giovane sia fuorviata dai computer e così tende a pensare che Fischer non giocasse con avversari così bravi, che all’epoca non fossero poi così preparati e cose simili. Poi, quando lo vedi, quando lo incontri, ed è chiaro che non è nel momento del suo fulgore, e ti accorgi di quanto sia ancora così brillante, beh allora inizi a nutrire un tale rispetto... Sono felice di aver avuto quel periodo con lui, perché sono arrivato a conoscerlo bene e ho capito che dentro è un’ottima persona.
– Ti ha ispirato?
– Sì, senza dubbio.
– Ti spingeva ad andare avanti?
– No, lui non spingeva nessuno. Stava spesso da solo, voglio dire, per lo più. Ma per me è stato un periodo molto bello e mi ha ispirato tantissimo.
– Già, non stento a crederlo.
Lékó onorò comunque in vita il “maestro”, allorché a Magonza nel 2001 si consacrò primo Campione del Mondo di scacchi Fischerandom della storia di specialità. Un idillio cominciato in verità nel 1996 a Kanjiza, cittadina serba al confine con l’Ungheria, già covo del “latitante” Fischer nei primi anni ’90, e dove l’allora giovanissimo Péter si impose con 9½ su 11 nel primo torneo di Fischerandom della storia eterodossa.
