context: 1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... g8f6  4. d2d3  4... h7h6 A flexible move that keeps several plans open: he can play g7-g5 and Bg7, a bold idea that became popular a few years ago; or play g6-Bg7; or simply develop the bishop on its natural square, c5, without White being able to play Bc1-g5. 5. c2c3  5... f8c5  6. b2b4  6... c5e7  7. a2a4  7... d7d6  8. d1b3  8... e8g8  9. e1g1  9... c6b8 The knight returns so that Black can prepare c6-d5. A very difficult move for someone not familiar with this opening, but Nakamura has this very well studied. 10. a4a5  10... c7c6  11. b3a2  11... d6d5  12. c4b3  12... d8c7 Defending the e5-pawn. 13. f1e1  13... f8e8  14. b1d2  14... c8e6  15. c1b2 White's pieces on the queenside make a funny impression. 15... b8d7  16. d2f1  16... e7f8 White has no good plan to improve the position, and he is overextended on the queenside. 17. f3d2 Protecting the pawn on e4 so that the other knight can go to e3. 17... a8d8  18. f1e3  18... b7b5 An excellent move to gain space on the queenside. 19. a5b6  19... a7b6  20. a1d1  20... d8a8  21. a2b1  21... b6b5 Preparing Nb6-a4. Black already has a considerable positional advantage. 22. h2h3  22... a8d8  23. b1a2 Not the best square for the queen, but maybe Nepomniachtchi was counting on a draw by move repetition. 23... d7b6 Of course, Nakamura decides to play on, instead of repeating moves with 23...Ra8. 24. e3f1  24... d8a8  25. a2b1  25... a8d8  26. b1a2 Again looking for a repetition, but this isn't the best square. 26... d8d7  27. b2c1  27... d5d4  28. b3e6  28... e8e6  29. a2b3  29... d4c3  30. b3c3  30... c7d6 The b4-pawn falls. 31. d2f3  31... d6b4 With surprising ease, Nakamura has gained a decisive advantage. 32. c3a1  32... b4e7  33. c1b2  33... d7a7  34. a1b1  34... b6a4  35. b2a1  35... e7e8 I like this move, clearing the diagonal for the bishop and defending the c6-pawn, thus reducing the strength of the d3-d4 advance, which Nepomniachtchi decides to play anyway. 36. d3d4 Sacrificing another pawn. 36... e5d4  37. f3d4  37... e6e4  38. f1g3  38... e4e1  39. d1e1  39... a7e7  40. e1e7  40... e8e7 A good and solid move. 41. d4c6  41... e7c5 Black has given back one of the pawns, but the b-pawn is more than enough for victory. 42. c6e5  42... c5d5  43. e5d3  43... f6h5 This is a rapid game, and the lack of time on the clock will affect the players' accuracy in the endgame. 44. g3h5  44... d5h5  45. d3e5 The b-pawn is attacked. 45... h5e2  46. b1b3 Blundering the f-pawn. 46... e2e1  47. g1h2  47... e1f2 Black is two pawns up and has a totally winning position. But nothing is too easy with little time on the clock. 48. a1d4  48... f2f5  49. e5f3  49... f5f4  50. h2g1  50... f4c1  51. g1h2  51... f8d6  52. g2g3  52... c1c4  53. b3e3  53... c4c2  54. h2g1  54... g8h7  55. f3e5  55... c2b1  56. g1g2  56... b1f5  57. g3g4  57... f5c2  58. g2f3 Of course, Black could have played differently in the previous moves, but his play has been good enough so far. 58... f7f6 It's better to capture the knight before playing this move. 59. e5d3 Now Qe4+ is an unpleasant threat. 59... c2c4  60. e3e4  60... h7g8  61. f3e3  61... d6f8  62. e4e8  62... a4c3 Black now loses the b-pawn. 63. d4c3  63... c4c3  64. e8b5 With pawns on the same flank and the excellent combination of queen and knight, White has no problems achieving a draw. 64... c3c7  65. b5d5  65... g8h8  66. e3f3  66... c7h2  67. d3f2  67... f8d6  68. d5a8  68... d6b8  69. a8e4  69... h2g3  70. f3e2  70... b8e5  71. e4a8  71... e5b8  72. a8e4  72... g3c7  73. e4e8  73... h8h7  74. e8e4  74... g7g6  75. e2f3  75... h7g7  76. f3g2  76... c7g3  77. g2f1  77... g3c7
