Plans Gone Wrong

侯逸凡 (Hóu Yìfán) – Pentala Harikrishna
5th György Marx Memorial; Paks, August 9, 2007
Spanish Game C88

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. 0-0 Be7 6. Re1 b5 7. Bb3 0-0 8. a4 b4 9. d3 d6 10. a5 Be6. If 10. ... Bg4?! then 11. Be3 (11. Nbd2 Nd4 12. Bc4±) 11. ... d5 12. Nbd2± (Suat Atalık’s analysis).
11. Nbd2 Qc8 12. Nc4 Rb8 13. h3 h6 14. Be3 Nh7TN (14. ... Rd8 15. Qe2 Bf8 16. Nfd2 Ne7 17. d4 Ng6 18. d5 Bd7 19. Ba4 Bb5 20. b3 Be7 21. Rec1 c6 22. Bxb5 Rxb5 23. Nb6 Qb7 24. dxc6 Qxc6 25. Qc4 ½ : ½ M. Adams – Anand, FIDE World Chess Championship Tournament, Potrero de los Funes 2005)
15. d4 exd4 16. Nxd4 Nxd4 17. Bxd4 Rb5 18. f4 Bf6∞


19. f5!? (19. Bf2 d5!⇄)
19. ... Bxc4 20. Bxc4 Bxd4+ 21. Qxd4 Re5


22. Qd3?! A bit tortuous, perhaps. More prudent seems 22. Bd3 Qb7 23. Ra4 Rb8= with equality.
22. ... Nf6 23. Bxa6 Qa8 24. Bb5?! If nothing else 24. Bc4 saves a tempo, in the sense that it does not call Black’s King’s Rook to a higher purpose. Anyway, after 24. ... Rxa5 25. Rxa5 Qxa5 Black would recover the Pawn with interest.
24. ... Rb8 25. Bc4 Rxa5 26. Rxa5 Qxa5 27. Qb3 Rf8. After all, it’s all like before.
28. Kh1 Qc5 29. c3 bxc3


30. Qxc3? This turned out to be White’s crucial mistake, since it leaves her with weak Pawns. Her best was doubtless 30. e5! dxe5 31. Qxc3 regaining the Pawn with good equalising prospects.
30. ... Re8 31. Bd3 Qxc3 32. bxc3 Re5 33. Re2 Kf8 34. Kg1 Rc5 35. Rc2 d5 36. e5. Likewise after 36. exd5 Rxd5 37. Rd2 Ne4 38. c4 Rd4 39. Rd1 Nd6 Black wins a Pawn, and with it the game.
31. ... Nd7 37. e6 Ne5 38. Bf1 d4 39. c4 fxe6 40. fxe6 Ke7 41. Rd2 Nc6 42. Rf2 Kxe6 43. Rf8 Rf5 44. Re8+ Kd6 45. Bd3 Re5 46. Rg8 Re7 47. Kf2 Kc5 48. Ra8 Ne5 49. Ra5+ Kb4 50. Rb5+ Kc3 0 : 1.

Just another happy ending gone wrong. Photo: marxgy.ase.hu.
