Black has fallen into tremendous passivity. There is no longer any doubt about the final result.
1. e2e4  1... e7e5  2. g1f3  2... g8f6  3. f3e5  3... d7d6  4. e5d3 The rarest of the knight retreats in this position of the Petroff Defense. White's idea is to exchange queens and press an endgame that is close to equality. Honestly, it's a choice closer to Carlsen's style than Vachier-Lagrave's, but the French GM will show that he can play technical endgames with the same skill he plays dynamic middlegames. 4... f6e4  5. d1e2  5... d8e7  6. d3f4  6... e4f6  7. d2d4  7... e7e2  8. f1e2 Examining the results of the games played by strong grandmasters in this position, I get the impression that White's performance is much better than the computer's evaluation indicates. This shows that it's not so simple to defend the endgame. 8... b8c6  9. c2c3  9... d6d5  10. f2f3 A useful move, freeing the f2-square for the king and taking the e4-square from Black's knight. 10... c6d8 [%c_effect d8;square;d8;type;GreatFind;persistent;true] An excellent move. The knight is not doing much on c6, so it's repositioned and the pawn moves to the square, reinforcing the center. 11. e1f2 Already a new move. 11... f8d6  12. b1a3  12... c7c6  13. a3c2  13... c8f5  14. f4d3  14... h7h5 It's not clear that this move is better than the more timid pawn advance to h6. 15. c1g5  15... f6d7 Black doesn't need to be too worried about the capture on f6. 16. c2e3  16... f5h7  17. g5f4  17... e8e7  18. f4d6  18... e7d6  19. d3f4  19... h5h4  20. g2g3 White tries to open the h-file to put pressure on the kingside. 20... g7g5  21. f4g2 A critical moment. 21... h4h3 [%c_effect h3;square;h3;type;Inaccuracy;persistent;true] This move creates long-term problems for Black, as the h3-pawn becomes a weakness that will be a constant headache. There are two good alternatives. 22. g2e1  22... d8e6  23. e2d3 [%c_effect d3;square;d3;type;GreatFind;persistent;true] Controlling the f5-square. 23... a8f8  24. d3f5  24... h7g8 [%c_effect g8;square;g8;type;Inaccuracy;persistent;true] Not all ugly moves are bad, but this one is. It's better to capture the bishop. 25. e1d3  25... e6g7  26. f5d7 White has many tempting options and it's not easy to play in the most accurate way. 26... d6d7  27. e3g4 It's probably better to bring the rook to e1 or start advancing the queenside in order to create weaknesses in Black's position. 27... f7f6  28. d3c5  28... d7c8  29. h1e1  29... h8h7 [%c_effect h7;square;h7;type;Mistake;persistent;true] This is a clear mistake. The knight should be attacked immediately. 30. e1e2 [%c_effect e2;square;e2;type;Inaccuracy;persistent;true] 30... b7b6  31. c5d3  31... c8d7  32. a2a4 [%c_effect a4;square;a4;type;GreatFind;persistent;true] 32... a7a5 [%c_effect a5;square;a5;type;Mistake;persistent;true] The fatal mistake. There's no way to defend the queenside now. 33. b2b4 [%c_effect b4;square;b4;type;GreatFind;persistent;true] 33... a5b4  34. d3b4 a4-a5 is coming and Black's king is very insecure. Black's pieces are poorly placed on the kingside. Vachier Lagrave achieves the type of position he loves so much, with initiative and an attack. 34... c6c5  35. b4d3  35... c5d4  36. c3d4  36... g7e6  37. e2b2 [%c_effect b2;square;b2;type;GreatFind;persistent;true] 37... e6d4  38. b2b6 All the white pieces are able to participate in the attack. 38... h7e7  39. a1a2 A solid and practical choice for a rapid game, preventing the black rook from going to e2. 39... g8e6  40. g4e3  40... f8a8  41. a4a5  41... d7e8  42. a5a6  42... e8f7
