Sicilian Defence B32

1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5 5. Nb5 d6 6. c4 g6. For 6. ... Be7 7. N1c3 a6 8. Na3 Be6 9. Be2 Bg5 see Svidler – Andreikin, World Chess Championship Candidates, Khanty-Mansiysk 2014. 7. Be3 Be6 8. N1c3 a6 9. Na3 Nf6 10. Be2 Bg7 11. Nc2 Rc8 12. Rc1 0-0 13. 0-0 Ne7 14. Na3 Nc6 15. Re1 Nd4 16. f3 Qb6 17. Rb1 Nxe2+ 18. Rxe2 Qb4 19. Rd2 Rfd8 20. c5? In the post-mortem directly after game Ivanchuk criticized this move. 20. Qb3 was worth considering. 20. ... Qa5 21. Rxd6 Bf8 22. Rxd8 Rxd8 23. Qe2 Bxc5 24. Nc2. Black has a shining initiative, and his Bishop-pair may soon become quite effective. 24. ... Bd4 25. Qe1 b5? This throws away any advantage. 25. ... Rd7 would have kept a definite edge for Black. 26. Nxd4 exd4 27. Bg5. A forced move, but a good one! 27. ... dxc3 28. Qxc3. On 28. Bxf6? Bxa2! would be a win for Black. 28. ... Qxc3 29. bxc3 Bxa2 30. Bxf6 Rd6. Else 30. ... Bxb1 would be a dead draw in a Bishops of opposite colours ending. 31. Be5 Re6 32. Ra1 Rxe5 33. Rxa2 Re6 34. Kf2 Kf8 35. Ke3 Ke7 36. g4 Kd7 37. f4 Rc6 38. Kd4 Kc7. “Risky”, Ivanchuk said. 39. f5 Rc4+ 40. Kd5 Kb6 41. Ra3 a5 42. e5

42. ... Ra4?? A tragic blunder! 42. ... gxf5! 43. gxf5 Rf4! 44. f6 Rf3! 45. Kd6 Re3 is still a double-edged endgame, but probably a draw. 43. Rxa4 1 : 0. For after 43. ... bxa4 44. Kc4 gxf5 45. gxf5 Kc6 46. Kd3 Kd5 47. e6 fxe6 48. f6 Kd6 49. c4 e5 50. c5+ Ke6 51. c6 e4+ 52. Kc2 White wins. “It’s not so difficult for a good Grandmaster...”, Ivanchuk said.
