1. d4 d5 2. c4 e6 3. Nf3 Nf6 4. Nc3 c6 5. e3 Nbd7 6. Qc2 Bd6 7. Bd3 dxc4 8. Bxc4 b5 9. Bd3 Bb7 10. 0-0 a6 11. Ng5. Somewhat inconsistent. For 11. e4 e5 12. Bg5 see Ni – Ingvason, Reykjavik 2010. 11. ... Qc7 12. h3 c5 13. Nge4 Be7 14. Nxf6+ Nxf6 15. dxc5 Qxc5 16. e4 Rc8 17. a3 0-0 18. Qe2 Qe5 19. f4 Qb8 20. e5 Nd5 21. Nxd5 Bxd5 22. Be3 g6 23. a4 Bc4 24. Rfc1 Bxd3 25. Qxd3 Rxc1+ 26. Rxc1 bxa4 27. Qxa6 Qb3 28. Qe2 Rb8 29. Rc2 h5 30. Bc1 Rd8 31. Kh2. A questionable prophylaxis. But also in case of 31. Rc3 Rd1+ 32. Kh2 Qd5 we’d prefer Black. 31. ... Rd3. Infiltration. 32. Rd2 Rxd2 33. Qxd2 h4 34. Qf2 Kf8 35. Be3 Ke8 36. Qd2 Bb4 37. Qd4 Be7 38. Bf2 Qc2 39. Be3 Qb3 40. Bf2? A grave faux pas. After 40. Qd2!? Qc4 White’s game is tenable. 40. ... Qb4! The right track. White cannot hold the ending. 41. Kg1 Qxd4 42. Bxd4 Kd7 43. Kf2 Kc6 44. Ke3. A bad move, but also after 44. Ke2 Kd5 45. Kd3 g5! White loses. 44. ... Bc5 45. Kd3 Bxd4 46. Kxd4 Kb5. So far so easy so clear. 47. Kc3 Kc5 48. Kd3 Kb4 49. Kc2 Kc4 50. Kb1 Kd3 51. Ka2 Ke3 52. Ka3

52. ... Kf2! Prettily calculated. 53. Kxa4 Kxg2 54. b4 Kxh3 55. b5 Kg4 56. b6 h3 57. b7 h2 58. b8=Q h1=Q 59. Qf8 Qe4+ 0 : 1.
