1. e2e4  1... e7e5  2. g1f3  2... g8f6  3. f3e5  3... d7d6  4. e5c4 An alternative to the more popular 4.Nf3. It has been played by some strong grandmasters, despite its harmless appearance and computer disapproval. 4... f6e4  5. d1e2  5... d8e7  6. b1c3 A rare choice. 6... e4c3  7. b2c3  7... c8g4 This novelty was played after some thought. 8. e2e7 Vidit clearly didn't expect Black's previous move. 8... f8e7  9. a1b1  9... b7b6  10. d2d4 Black will get a good position, so it's time for White to look for alternatives. 10... g4e6  11. a2a4 Moving the pawn so the knight can move, but the pawn on a4 can also be a target. 11... e8g8  12. c4e3  12... e7g5  13. c3c4  13... f8e8  14. h2h4 It's necessary to remove the bishop from its active position. 14... g5f6  15. c2c3  15... c7c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] Black's position is already more comfortable. 16. f1d3 [%c_effect d3;square;d3;type;GreatFind;persistent;true] Vidit reacts well to complicate the game. 16... b8c6 There are other tempting moves. 17. d4d5  17... c6e5  18. d3h7 [%c_effect h7;square;h7;type;GreatFind;persistent;true] 18... g8h7  19. d5e6  19... f7e6  20. e1e2 The position has completely changed, and the ending we see now is difficult to assess and will remain difficult until the last moves of the game. Theoretically, Black's pawn structure is better, with fewer weaknesses, but White's pawns on the kingside are very mobile. 20... a8d8  21. g2g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] White has to stay active. 21... g7g6  22. g4g5  22... f6g7  23. a4a5 [%c_effect a5;square;a5;type;GreatFind;persistent;true] Another good move. White sacrifices a pawn, gives Black a passer, but exchanges rooks; this makes it easier to attack Black's pawns. 23... b6a5  24. b1b7  24... d8d7  25. b7d7  25... e5d7  26. h1d1  26... g7f8  27. e3g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] Vidit handles the initial part of the endgame with great accuracy. He prepares Bf4, and the knight is excellently-placed on g4, threatening to go to f6 if its colleague leaves d7. 27... e8b8  28. c1f4  28... b8b2  29. e2f3  29... e6e5 A risky move that weakens the light squares, but Nepomniachtchi takes his chances in order to fight for the full point. 30. f4e3  30... d7b6 Another dangerous decision, allowing the knight to go to f6. 31. g4f6  31... h7h8  32. f3e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] The king gets ready to destroy Black's position if the knight takes on c4. The position is objectively equal but only if Black finds many forced and difficult moves. In practice, it's already much better for White. 32... a5a4 [%c_effect a4;square;a4;type;GreatFind;persistent;true] The best defense. 33. d1a1  33... b2b3 [%c_effect b3;square;b3;type;Mistake;persistent;true] 34. e4d3 [%c_effect d3;square;d3;type;Mistake;persistent;true] 34... a4a3  35. e3c1 The position remains difficult to defend, and here comes another mistake. 35... a7a5 [%c_effect a5;square;a5;type;Mistake;persistent;true] 36. c1a3  36... d6d5 This is Nepomniachtchi's idea, but it loses in more than one way. 37. d3c2 [%c_effect c2;square;c2;type;Mistake;persistent;true] Missing a golden chance. White had two winning moves. 37... d5c4  38. f6e4  38... b3b5 The worst has passed for Black. 39. a1d1  39... f8e7  40. d1e1  40... h8g7  41. e4d2  41... e7d6  42. d2e4  42... d6e7  43. e4g3 It's Vidit turn to show that he is playing for a win: a decision he will regret but that we are thankful for. 43... b5b3  44. a3c1  44... b6d5  45. g3e4  45... g7f7 Bringing the king to the center. 46. c1d2  46... a5a4  47. e1a1  47... d5b6  48. d2e3  48... b3b5  49. e4d2  49... b5a5  50. c2b2 The king marches to a3 in order to stop the pawn. It's still good enough for a draw, but White's life is getting more and more difficult. 50... f7e6  51. b2a3 One of the kings heads towards the center and the other to the flank. 51... a5b5  52. a1c1  52... e6f5  53. f2f3  53... b6d5  54. a3a4  54... b5b8  55. d2c4  55... e5e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] The computer continues to indicate equality without getting disturbed, but what we need to understand is that there's a computer game and a human game. In fact, understanding this \"human factor\" is one of the secrets of modern chess; that is, understanding which positions are equal for the computer but not for the flesh-and-blood chess player. Just compare both kings, and it's clear that the defense is not easy. It's actually surprising to me that the position is equal. 56. f3e4  56... f5e4  57. e3f2 For now, Vidit defends well. 57... e4d3  58. f2g3  58... d5c3  59. a4a3  59... b8b4 The last critical moment of the game. 60. c4b2 [%c_effect b2;square;b2;type;Mistake;persistent;true] A fatal mistake.
