Spanish Game C67
1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. 0-0 Nxe4 5. Re1 Nd6 6. Nxe5 Be7 7. Bf1 Nxe5 8. Rxe5 0-0 9. d4 Bf6 10. Re1 Re8 11. c3 Rxe1 12. Qxe1 Ne8 13. d5 d6 14. Nd2 c6 15. Ne4 Be7 16. Bf4 cxd5 17. Ng3 Be6 18. Bd3 Bg5 19. Qe3 Bxf4 20. Qxf4 Qf6 21. Qb4 Qe7 22. Re1 Qd7 23. Ne2 a5 24. Qb6 Qc7 25. Qe3 Nf6 26. Nd4 Re8 27. Qg3 Bd7 28. Rxe8+ Nxe8 29. Qe3 Qd8 30. f3 Nf6 31. Be2 Kf8 32. g4 h6 33. Kf2 Qe7 34. Qxe7+ Kxe7. A probably equal endgame has arisen as Black’s extra Pawn is almost nullified by the doubled Pawn on the d-file. 35. Ke3 g5 36. h3 h5 37. Bd3 hxg4 38. hxg4 Be6 39. b3 Nd7 40. Nc2. If 40. Nf5+ then 40. ... Bxf5 41. Bxf5 Ne5 42. Bc8 b6 43. Bb7 Ke6 44. Bc8+ Ke7 with a draw by repetition. 40. ... Ne5 41. Be2 Ng6 42. Bd3 Nf4 43. Bh7 Kf6 44. Nd4 Ke5 45. Bc2 Bd7 46. Bb1 Ng2+ 47. Kf2 Nh4 48. Kg3 f5 49. f4+ Kf6 50. fxg5+ Kxg5 51. gxf5 Bxf5 52. Nxf5 Nxf5+ 53. Kf3. Of course the King and Pawn ending would be lost for White. 53. ... d4 54. cxd4 Nxd4+ 55. Ke4 Nb5
56. Kd3? 56. Kd5! Nc3+ 57. Kxd6 Nxb1 58. Kc7 draws. 57. ... Kf4? 57. ... Na3!−+ is only too easy to miss it! 57. a4 Nc7 58. Kd4 b6 59. Bc2 Kf3 60. Bd3 Kf2
61. Kc4? White rashly allows the d-Pawn to advance, with disastrous consequences for her own doom. Almost any other move would have been good enough for a draw. 61. ... Ke3−+ 62. Bf1 (62. Kc3 d5−+) 62. ... d5+ 63. Kc3 Ne6 64. b4 Nd4 65. Ba6 Nf5 0 : 1.
