context: 1. e2e4  1... c7c5  2. g1f3  2... e7e6  3. d2d4  3... c5d4  4. f3d4  4... b8c6  5. b1c3  5... d8c7  6. c1e3  6... a7a6  7. a2a3 A cunning way of meeting the Taimanov variation. It's much more dangerous than it looks and has been played many times by strong GMs. 7... b7b5 This is probably the most reliable move. 8. d4c6  8... c7c6  9. d1d4 A curious move and not the most popular. 9... c6d6 A rare move, offering a queen exchange. Black faces some problems on the queenside, so this is probably not the most accurate. 10. e1c1  10... d6d4  11. e3d4  11... c8b7  12. f2f3  12... g8e7 A typical maneuver: the knight is heading to c6. It seems that Black is close to equalizing, but now comes a surprise. 13. a3a4 A new move that proves an advantage for White. 13... b5b4  14. c3a2  14... e7c6  15. d4f2  15... f8e7  16. c1b1  16... d7d6 Too passive. 17. a2c1  17... e8g8  18. c1b3 The endgame is very unpleasant for Black. He doesn't have an active plan, and the d6-pawn will suffer pressure from a bishop on g3. The queenside overall is a bit shaky. 18... f8c8  19. f2g3  19... e7f8 This doesn't help Black's position, although it's difficult to recommend active moves. 20. f1e2  20... e6e5 A big positional concession. 21. d1d2  21... a6a5  22. g3f2  22... b7a6 Black tries to do something, but the position becomes even worse after the bishop exchange. 23. e2a6  23... a8a6  24. h1d1  24... f7f6  25. d2d5 White is strategically winning due to the weaknesses on the light squares. 25... g8f7  26. d5b5  26... f7e6  27. d1d5  27... c8a8 The queenside is nearly collapsing. 28. b5b6  28... f8e7  29. b6b7  29... f6f5 Trying some counterplay on the kingside. 30. b3d2  30... f5e4  31. f3e4  31... a8c8  32. f2e3 Nepomniachtchi is not in a hurry. 32... c6d8  33. b7b6  33... a6a8  34. b2b3 The knight is going to c4. 34... d8f7  35. d2c4  35... e7d8  36. b6b7  36... d8c7  37. b7b5  37... f7d8  38. e3b6  38... a8a6  39. b6c7  39... c8c7  40. c4a5 It's time to start harvesting. 40... d8f7  41. b5b4  41... f7g5  42. d5b5  42... c7c5  43. a5b7  43... c5c7  44. h2h4  44... g5f7  45. b7a5  45... g7g5  46. h4h5  46... g5g4  47. a5c4  47... f7g5  48. b5b7  48... c7b7  49. b4b7  49... g5e4  50. b7h7 With two distant passed pawns and a material advantage, the win is certain. 50... e6f5  51. h5h6  51... d6d5  52. c4e3  52... f5e6  53. h7g7  53... a6a8  54. e3g4  54... d5d4  55. h6h7  55... a8h8  56. a4a5 It's impossible to cope with both pawns.
