1. d2d4  1... d7d5  2. c2c4  2... d5c4  3. e2e3  3... g8f6  4. f1c4  4... e7e6  5. g1f3  5... a7a6  6. e1g1  6... c7c5  7. c4e2 [%c_effect e2;square;e2;type;Interesting;persistent;true] Only the tenth most popular choice in this Queen's Gambit Accepted position, which shows how rich it is. White has the most diverse options, such as 7.a4, which was played by Botvinnik in the match against Petrosian, and the solid 7.dxc5, which was played by Kramnik in the match against Kasparov (he also played 7.a4 in one of the games), or the more ambitious 7.Bb3, which I played several times, among other moves. 7... b8d7  8. b1c3  8... b7b5 The position ended up transposing into a known line, with a lot of theory, which sometimes occurs in a different order of moves. 9. d4d5 A critical attempt. 9... e6d5  10. c3d5  10... c8b7  11. d5f6  11... d8f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true] 12. a2a4  12... b5b4  13. e3e4 All of this is still well-known. 13... h7h6 [%c_effect h6;square;h6;type;GreatFind;persistent;true] A good prophylactic move to prevent an attack from White's bishop on g5. 14. d1c2  14... f8d6  15. c1e3  15... e8g8  16. a1d1  16... a8d8  17. f3d2  17... d6f4 A new move. The bishop exchange is useful against White's plan to play f4-e5. 18. e3f4  18... f6f4  19. g2g3  19... f4f6  20. a4a5 Fixing the pawn on a6, although it's not so clear to me what's the benefit of this. 20... f6e7 It's clear that Black has no problems and has several possible moves. 21. d1c1 Another difficult move. Maybe the idea is to reposition the rooks, preparing to bring the other one to d1, but that seems a bit superficial. 21... f7f5 [%c_effect f5;square;f5;type;Interesting;persistent;true] 22. e2c4  22... g8h8  23. c4d5 At this point we have to understand that Black is pushing for the initiative and White is trying to force a draw. 23... b7c8 [%c_effect c8;square;c8;type;Interesting;persistent;true] Abdusattorov keeps pushing for a win. 24. e4f5  24... d7e5 This is the point of Black's previous move. 25. d5e4  25... c8f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] 26. c2c5 The only move. 26... e7e8 Again refusing a draw. 27. f2f4 [%c_effect f4;square;f4;type;GreatFind;persistent;true] So defends with resourcefulness. 27... f5e4  28. f4e5  28... f8f1  29. c1f1 White can finally breathe calmly. 29... e4d3 A step in the wrong direction.. 30. f1e1  30... e8e6  31. c5b6 A solid choice. 31... e6d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] 32. e5e6 The pawn marches on and the game becomes sharp again, although the position still remains equal. 32... d3b5  33. e6e7  33... d8e8  34. b6f2  34... b5c6 With this powerful battery, Black always has some chances. 35. d2e4  35... d5d7 [%c_effect d7;square;d7;type;Mistake;persistent;true] The first real mistake of the game. 36. f2f8  36... h8h7  37. f8f7  37... h7h8  38. f7f8  38... h8h7  39. f8f7  39... h7h8  40. e4f2 [%c_effect f2;square;f2;type;GreatFind;persistent;true] Now White has managed to stabilize the powerful extra pawn on e7 and has a decisive advantage, but there's still a lot of work left to put the point in the pocket. 40... c6b7  41. h2h4 [%c_effect h4;square;h4;type;GreatFind;persistent;true] White is not in a hurry and takes time to improve his position. 41... b7c6  42. f7e6  42... d7c7  43. g1h2
