Be3 (13. a5) 13. ... Rb8 (13. ... Qe7 14. f3 Nh5!?) 14. Qd2 Qe7 15. f3 Ne8 16. Kh1 Nc7 17. Rab1? (17. Bg5) 17. ... b5 with good play for Black, Topel – 侯逸凡 (Hóu Yìfán), 1st World Mind Sports Games, Women’s Team Blitz Tournament, 北京 (Běijīng) 2008. 11. ... Qe7 12. 0-0 Nbd7 13. Re1 0-0 14. a5 Ne8 15.

Rxa6 Nd4 the position is in dynamic equilibrium — but maybe a little easier for Black. 24. ... Rxc4 25. Qd2 Qe7 26. Bf4 Qd7 27. Qd3 Rb4 28. Qg3 Rd8


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. ... Qxe4 35. h3 (35. Bxc5?? Qc2−+) 35. ... Bd4 36. Qb3 Qf5 37. Rc1 Qxf2+ 38. Kh2 Qe3 39. Qxe3 Bxe3 40. Bc7 Rxd5 41. Ra1 Rd7 42. Bb6 Rd6 43. Rxa6 Kg7 44. Ra3 Bf4+ 45. g3 Bxg3+ 46. Kxg3 Rxb6 0 : 1.

16. Rh4! Nc5 17. Rd1. White didn’t need to castle to find the best synthesis between King safety and development. 17. ... 0-0 18. Rg4 f5?! 19. Rgd4 Rad8 20. Nh4 Rf7 21. Ng6 Ne6 22. Rd5 Nf8 23. Nf4 Rc8 24. b3 e6


25. R5d4? It does seem quite a doubtful offer. White could simply continue 25. Rd6 b5 26. R1d4 maintaining her powerful bind. 25. ... Qxe5 26. Ng6 Qh2 27. Rh4 Qc7 28. Qc3 Nxg6. 28. ... d5 doesn’t make all that difference, as after 29. Qe1 Black would take on g6 anyway. 29. hxg6 Rf6 30. Rxh6 b5?? A self-mating blunder due to time shortage. 30. ... Qf4! seems fine for Black.


31. Rh8+! Kxh8 32. Qh3+ Kg8 33. Qh7+ Kf8 34. Qh8+ Ke7 35. Qxg7+ Ke8 36. Qxf6 Qh2 37. Qf7+ 1 : 0.

20. Rcd1? In a typical isolani position with pros and cons, 侯逸凡 (Hóu Yìfán) falls asleep and makes a grave mistake that loses a Pawn for nothing.
20. ... Nxe4 21. Nxe4 Bxh2+! 22. Kxh2 Bxe4 23. Bxe4 Qh4+ 24. Kg1 Qxe4. Finally Black has gained the Pawn almost for free as she is already eyeing the isolated d4-Pawn, so now it is no longer a matter of good and bad ideas, but rather a matter of technique.
25. Qa6. Also deserving consideration is 25. d5!? so as to interfere on the diagonal a8-h1 after 25. ... exd5 26. Qa6 — if nothing else, that may offer a more stubborn resistance.

Qf3 Nf6. A tabiya from the Scheveningen Variation, which usually ends here with a draw by repetition, the first occurrence being in Psakhis – Kasparov, 30th Chess Olympiad, Manila 1992. 阮露斐 (Ruǎn Lùfěi) tries for a win instead, but with little luck. 19.

Another Date

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 International Master Evgeny Yakovlevich Gik, «Наука и жизнь» (Science and Life), No. 11, 2008.

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 d6 9. c3 Bg4 10. d3. 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. A senseless jump: the Knight will be kicked back immediately. 22. ... Qd8 23. Kg2 g6 24. Ng3 Kg7 25. Rh1 Rh8 26. Nhf1 Qf6 27. Be3 Bxe3 28. Nxe3 Ng5 29. Qe2. 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.

Kosteniuk’s one and only victory in the Final match with 侯逸凡 (Hóu Yìfán) sealed the fate of the Women’s World Chess Championship 2008. Photo: Evgeny Yakovlevich Gik Archive.
