Another endgame win

July 19, 2010
Replay (I was white)
1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Bf5 5. Ng3 Bg6 6. h4 h6 7. Nf3 Nd7 8. h5 Bh7 9. Bd3 Bxd3 10. Qxd3 e6 11. Bf4 Ngf6 12. O-O-O Nd5 13. Bd2 Bd6
As main line a Caro-Kann as possible. 13… Nb4 14. Qb3 a5 15. Kb1 a4 was an alternative, going straight after the white king.
14. Ne4 Bc7 15. g3 N7f6 16. Ne5 Nxe4 17. Qxe4 Nf6 18. Qe2 O-O?!
If 18… Qxd4, grabbing a pawn 19. Ng6 Rg8 (19… fxg6? 20. Qxe6+ Kf8 (20… Kd8 21. Bc3) 21. hxg6 Qd7 22. Bb4+) 20. Bf4 Bxf4+ 21. Nxf4 Qa4 22. Kb1 with good compensation for the pawn.
19. c3
19. Bb4 Re8 20. c4 was an alternative
19… c5
(19… Qd5)
20. Ng4
(20. dxc5)
20… Nxg4
20… cxd4 21. Bxh6 gxh6 22. Nxh6+ Kh7 23. Rxd4 Qe7 24. Nf5 with a dangerous attack
21. Qxg4 Qf6
21… cxd4 22. Bxh6 Qf6 23. Bg5 Qxf2 24. Rxd4 is even according to the computer but looks pleasant for white.24. h6 dxc3 25. bxc3 Be5 26. hxg7 Bxg7 27. Rdf1 f5 28. Qh4 Qxa2 29. Qh7+ Kf7 30. Qh5+ Kg8 31. Qh7+ is a wild variation ending in perpetual check.
22. dxc5 Rac8 23. Be3 Rfd8 24. f4 Qf5 25. Qf3
(25. Qxf5 exf5 26. Kc2)
25… b6 26. g4 Qf6 27. Rdf1?
Going through with a sub-par idea. I hadn’t realised how safe black’s king was going to be on h7! (27. cxb6 Bxb6)
27… bxc5 28. g5 Qf5 29. gxh6 gxh6 30. Rhg1+ Kh7 31. Rg2 Rg8 32. Rfg1 Bd6 33. a4 Qd5 34. Rxg8 Rxg8 35. Qxd5 Rxg1+ 36. Bxg1 exd5 37. f5?
I had seen this position before I played my 33rd move and realised that the a-pawn would be the crucial one in the resulting endgame. Here I could have forced matters instead with 37. b4! Bxf4+ 38. Kc2 cxb4 39. Bxa7 bxc3 40. a5 Be5 41. a6 Kg7 42. Be3 Bb8 43. Kxc3 f5
37… a5? 38. Kd2
(38. f6)
38… Kg7 39. Be3 Kf6 40. Bxh6 Kxf5 41. Bg7? Kg5 42. h6 Kg6 43. Ke3 f5 44. Kf3 Kh7 45. Bf6! Kxh6??
Giving up the a-pawn. Now the king is too far to stop white’s a-pawn. (45… Bc7 46. Bg5 d4 47. c4 (47. cxd4 cxd4))
46. Bd8 d4
(46… Kg6)
47. cxd4 cxd4 48. Bxa5 Kg6
(48… Bc5 49. b4)
49. Bb6 Kf6 50. a5 Ke6 51. a6 Bb8 52. a7 1-0
