I'd like to know how top GMs manage to remember so much. 10. g4g5  10... d5d4  11. g5f6  11... d4c3  12. f6g7  12... f8g7 All these moves are the first choice of the computer. 13. f4f5 Now Vitiugov started to think. 13... c3b2 Black has many candidate moves. 14. c1b2  14... c7b6 A risky decision, going after the e4-pawn. This is playable, but not very practical. 15. b2a3  15... b6e3  16. f1e2  16... e3e4  17. h1g1 It's hard to imagine that Black can survive this position, but the computer actually evaluates it as equal. 17... g7f8 After this move Tabatabaei finally started to think. Excellent preparation. 18. d1d2 Very logical. 18... d7c5 [%c_effect c5;square;c5;type;Mistake;persistent;true] This move loses. There's only one acceptable continuation for Black. 19. f3g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] Tabatabaei conducts the attack with enviable precision from here on. 19... e4h4  20. g1g3  20... h7h6 Other moves are no better: 21. g5f7 [%c_effect f7;square;f7;type;GreatFind;persistent;true] It's necessary to destroy the king's protection. 21... c5e4 The best chance. 22. d2d5  22... e4g3  23. d5e5  23... e8f7  24. h2g3  24... h4h1  25. e1f2  25... h1c6  26. e2h5  26... f7g8  27. a3f8  27... h8h7  28. h5g6  28... h7c7  29. f8h6  29... c6c5  30. e5c5  30... c7c5  31. g3g4 By a miracle, Vitiugov has managed to avoid mate in the middlegame, but his king remains in danger even after the exchange of queens. 31... c5c2  32. f2g3  32... c8d7  33. a1e1  33... c2c6  34. e1e7  34... d7e8  35. g6h7  35... g8h8  36. h6f4  36... c6c5  37. f5f6  37... e8a4  38. h7g6  38... a8f8  39. g4g5  39... c5c3  40. g3f2  40... a4c2  41. g6c2  41... c3c2  42. f2g3  42... c2c5  43. e7b7  43... c5b5  44. b7a7  44... h8g8  45. a7g7  45... g8h8  46. g3g4  46... a6a5  47. f4d6  47... f8d8  48. d6e7 This doesn't spoil the game, but there's a simpler move. 48... d8c8  49. g4h5  49... c8g8
