6th Chess World Cup; tie-break game 4 (Blitz 10+10); Baku, September 29, 2015
Queen’s Pawn Game A40

1. Nf3 c5 2. c4 g6 3. d4 Bg7 4. d5 d6 5. Nc3 Bxc3+ 6. bxc3 f5. Peter Veniaminovich Svidler on Eljanov needing to win with Black: “I think mostly in the opening he should forget about the opening” :)”. 7. g3 Nf6 8. Bg2 Qa5 9. Qb3 Nbd7 10. Nd2 Nb6 11. 0-0 Bd7 12. Re1 Qa4 13. Bf1 Ne4 14. e3 0-0-0 15. Bd3 Nxd2 16. Bxd2 e5 17. f4 e4 18. Be2 h6 19. Kf2 g5 20. h4 Rdg8 21. Rh1 gxf4 22. exf4 Rg7. As a result of a very poor opening strategy by Karjakin Black has got a splendid position. 23. h5 Rhg8 24. Rhg1 Qa6 25. a4 Be8 26. Be1 Nd7 27. Ke3 Nf6 28. Rh1 Qa5 29. Bf2 b6 30. Rh3 Kd8 31. Be1 Ke7 32. Bf2 Kf8 33. Be1 Re7 34. Rh1 Rgg7 35. Ra3 Kg8 36. Bf2 Kh8 37. Be1 Rg8 38. Bf2 Reg7 39. Rh3 Qa6 40. Qd1? An amazingly bad move for White to make in his very inconvenient position, losing two Pawns. It is hard, however, to suggest any good move; maybe 40. Be1, although after 40. ... Ng4+ 41. Kd2 Re7 Black stands much better. 40. ... Ng4+ 41. Bxg4 fxg4 42. Rh1 Qxc4 43. Qe2 Qxd5 44. Rd1 Qe6 45. c4 Rd7 46. Rd5 Bf7 47. Be1 Qe8 48. Rf5 Kh7 49. Bc3 Be6 50. Rf6 Rf7 51. Rg6. In desperation, White sacrifices a third Pawn! 51. ... Rxg6 52. hxg6+ Kxg6 53. Ra1 h5 54. Rd1 Rd7 55. Qh2. White offers a fourth Pawn! 55. ... Qd8 56. Ba1 d5. Why not 56. ... Bxc4? 57. cxd5 Rxd5 58. Qb2 Rd3+ 59. Ke2 Qd4 60. Qxd4 cxd4 61. Rxd3 Bc4 62. Bxd4 exd3+ 63. Ke3. Karjakin managed to slip out into an ending with Bishops of opposite colours – even if two Pawns down. Both objectively and psychologically, it will turn out to be his saving clause!

63. ... Kf5 64. Bc3 a5 65. Be1 Ke6 66. Bc3 Kf5 67. Be1 Kf6 68. Bd2 Kg6 69. Bc3 Kf5. Here the drama of Eljanov: he fell into a threefold repetition that Karjakin claimed immediately! ½ : ½.
