Potluck

侯逸凡 (Hóu Yìfán) – 李超 (Lǐ Chāo)
2nd 海南 (Hǎinán) 儋州 (Dānzhōu) Super Grandmaster Chess Tournament; 儋州 (Dānzhōu), May 23, 2011
Sicilian Defence B67

1. e4 c5 2. Ne2 Nc6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 d6 6. Bg5 e6 7. Qd2 a6 8. 0-0-0 Bd7 9. f4 b5 10. Bxf6 gxf6 11. Kb1 b4 12. Nce2 Qb6 13. Qe1 h5!? A novelty in place of 13. ... Rc8, which was preferred by Croatian Grandmaster Zdenko Kožul, in fact a specialist of this line with Black: 14. Nxc6 Bxc6 15. Nd4 Bb7 16. f5 e5 17. Nf3 Rg8 18. Qh4 Ke7 19. Rg1 h5 20. Bd3 Bh6 21. g3 a5 22. Rg2 a4 23. Re2 b3! 24. a3 Rc3!! 25. Qxh5 Rb8 26. Qxh6 bxc2+ 27. Rxc2 Ba6! forcing a winning endgame, Shirov – Kožul, 16th European Team Chess Championship, Heraklion 2007.
14. Nxc6 Bxc6 15. f5. Maybe too hasty. Worth considering was 15. Nd4 followed by Bf1-c4, taking advantage of the absence of Black’s Rooks on the c-file.
15. ... e5 16. Qh4 Ke7 17. Ng3. 17. Rxd6 Bg7 18. Rd3 Bh6! also seems a little bit uncomfortable for White.
17. ... Bh6 18. Nxh5 Bg5 19. Qg4 Qc5 20. h4. 侯逸凡 (Hóu Yìfán) prepares for the “Rook lift”, at the cost, however, of allowing the activation of the enemy dark-square Bishop.
20. ... Be3 21. Rh3 a5 22. Qf3 Bd4 23. Ng3. Intending Ng3-e2.
23. ... Rhc8 24. Rd2. If 24. Bd3 then 24. ... b3! with a vehement attack.
24. ... Bc3! This must have been a bad surprise for White.
25. Rd1 Ba4 26. b3. It is not easy to suggest anything better. 26. Bd3 Bxb2! 27. Kxb2 Qc3+ 28. Kb1 Rab8! runs into a mating attack, and 26. Qd3 Bxb2! 27. Kxb2 Bxc2 28. Rc1 Bxd3 29. Rxc5 dxc5 30. Bxd3 c4 also looks awful. Maybe White should have contented herself with 26. Rd5 Qc7 allowing her opponent the upper hand.
26. ... Bxb3! 27. cxb3 a4 28. Bc4 axb3 29. Bxb3


29. ... Rxa2!! 30. Bxa2. Also after 30. Kxa2 Qa5+ 31. Kb1 Qa1+ 32. Kc2 Be1+ Black would mate in a few moves.
30. ... b3! 31. Bxb3 Qa3! 32. Kc2 Qb2+ 33. Kd3 Ba5! 34. Bc4 Rxc4! Another brick in the wall.
35. Ne2. Or 35. Kxc4 Qc2+ 36. Kb5 Qc5+ and mate next move. 35. ... Qc2+ 36. Ke3 Bb6+ 0–1.
