The Big Bounce

Anatoly Yevgenyevich Karpov – Mariya Muzychuk
2nd Trophée Karpov; knockout game 2; Cap d’Agde, November 1, 2013
Grünfeld Defence D90

“C’était une superbe partie. Je pense que tout le monde a pris énormément de plaisir. Karpov a montré une très grande technique dans la finale de Dame + Pion. Il a fini par gagner après 103 coups! C’est dommage que Mariya ait perdu de cette manière. Elle n’était pas obligée de donner 102. ... Qc5+. Elle pouvait encore jouer 102. ... Qa6+ et la partie continuait, même si elle aurait sans doute fini par perdre tôt ou tard cette position. Après l’échec croisé de Karpov par 103. Qc7+, c’est tout de suite fini”, Woman Grandmaster Nino Maisuradze said.

1. Nf3 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. h4 h6 6. e4 Nxc3 7. bxc3 Bg7 8. d4 c5 9. Be3 Qa5 10. Qd2 Nc6 11. Rc1 cxd4 12. cxd4 Qxd2+ 13. Kxd2 f5. For 13. ... 0-0 14. d5 Rd8 15. Ke1 Na5 see Pein – Williams, 4NCL 2013-2014, Hinckley 2013. 14. e5 Be6 15. Bc4 Bxc4 16. Rxc4 e6 17. Rb1 0-0-0 18. Ke2 Rd5 19. g3 Rhd8 20. Ne1 Bf8 21. Nd3 g5 22. hxg5 hxg5 23. Bxg5 Rxd4 24. Rxc6+ bxc6 25. Bxd8 Rxd8 26. Rh1 Ba3 27. Rh7 Rd7 28. Rxd7 Kxd7. “This ending is very difficult for Black, as her Pawns on c6 and e6 can only be defended by the King, because White’s King will be more active, and because White has the possibility of creating an outside passed Pawn with f2-f3 and g3-g4 to overload Black’s King”, Dennis Monokroussos said. 29. Kd2! “It’s important for White to activate his King (on c4) before Black can do the same with hers on the Queenside”, Monokroussos said. 29. ... Be7 30. Kc3 Bd8 31. Kc4 Bb6 32. Nc5+ Ke7 33. f3 Bc7 34. Kd4 Bb6 35. a4 a5 36. Kc4 Bc7 37. Nd3 Bb6 38. g4 fxg4 39. fxg4 Kf7 40. Ne1 Bf2? Already Black goes wrong. 40. ... Kg6 41. Nf3 Kh6 seems to give Black a tenable position. 41. Nf3 Kg6 42. Kd3? Karpov has a moment of hesitation. It was time for 42. Nd4! with consequences similar to those in the game. 42. ... Bb6 43. Ke4 Bf2? Repetita non iuvant. Correct was 43. ... Kh6 as after 44. Nd4 Kg5 45. Nxe6+ Kxg4 46. Nf8 Kg5 47. Nd7 Bc7 48. e6 Bd6 Black  holds the balance. 44. Nd4! Finally! 44. ... Bxd4 45. Kxd4 Kg5 46. Kc5 Kf4 47. Kb6! 47. Kxc6? Kxe5 leads to a dead draw. The most direct route to the basket, however, was 47. g5!! Kxg5 48. Kb6! winning easily for White.


47. ... c5!! A fantastic defensive idea, giving Black practical chances for survival, especially at knockout chess. 48. Kxa5? After 48. g5! c4 (much easier for White is 48. ... Kxg5?? 49. Kxa5+-) 49. g6 c3 50. g7 c2 51. g8=Q c1=Q 52. Qxe6 White retains excellent winning chances, although the ending is not “a walk in the park”, as a Deutsche Panzer optimistically called it. 48. ... Kxe5 49. g5 c4 50. Kb4 Kd4 51. g6 c3 52. g7 c2 53. g8=Q c1=Q. Any comments on what follows is merely academic. With a few seconds left for each player, it becomes more a matter of stamina than objecitivity. 54. Qd8+ Ke4 55. a5 Qb2+ 56. Kc5 Qc3+ 57. Kb5 Qb3+ 58. Kc6 Qc4+ 59. Kb7 Qb5+ 60. Qb6 Qd7+ 61. Qc7 Qb5+ 62. Ka7 Kf5 63. a6 e5 64. Qb6 Qd7+ 65. Kb8 Qe8+ 66. Kc7 Qe7+ 67. Kc6 Qe6+? Here 67. ... Qe8+ is the only move to draw according to tablebases. 68. Kc5 Qe7+ 69. Kc4 Qf7+ 70. Kb4 Qf8+ 71. Ka4 Qe8+ 72. Ka5 e4 73. a7 Qc8 74. Qb5+. More accurate is 74. Kb4! as if 74. ... Kg4 then 75. Qb8 and wins. 74. ... Kg4 75. Qd5 Qc3+ 76. Kb5 Qb2+ 77. Kc6 Qf6+ 78. Kc7 Qc3+ 79. Qc6? Qa5+? And here 79. ... Qe5+! was comparatively the best move – most probably the only move. 80. Kb7 Qb4+ 81. Kc8 Qf8+ 82. Kc7 Qf4+ 83. Qd6 Qc1+ 84. Qc6 Qf4+ 85. Kb6. Stronger was 85. Kb7! and if 85. ... Qf7+ then 86. Kb8 and wins. 85. ... Qf2+ 86. Qc5 Qb2+ 87. Kc6 Qf6+ 88. Kb7 Qf7+ 89. Kc8 Qe8+ 90. Kc7? Qf7+? Here 90. ... e3! draws. 91. Kb6 Qb3+ 92. Qb5 Qa3 93. Qd7+ Kf4 94. Qd5 Qb4+ 95. Kc7 Here 95. Qb5! was much stronger. 95. ... Qe7+ 96. Kb6 Qb4+ 97. Kc6 Qa4+ 98. Kb7 Qb4+ 99. Kc7 Qe7+ 100. Qd7 Qc5+ 101. Kb8 Qb6+ 102. Kc8 Qc5+? The last blunder. After 102. ... Qa6+ 103. Kd8 White ought to win surely, though laboriously, according to tablebases. But would have Karpov succeeded, with a few seconds on his clock? 103. Qc7+ 1 : 0.
