It's amazing how well Black's rook and knight coordinate in the next moves.
1. d2d4  1... g8f6  2. c2c4  2... e7e6  3. b1c3  3... f8b4  4. d1c2 This is one of the best options for White in the Nimzo-Indian. What can be more logical than preparing to capture the bishop with the queen $2 The problem is that the variations are so deeply studied that it's hard to fight for an advantage against a well-prepared opponent. 4... d7d5  5. c4d5  5... e6d5  6. c1g5  6... h7h6  7. g5h4  7... e8g8  8. e2e3  8... c7c5  9. d4c5  9... c8e6  10. g1f3  10... b8d7 This position is considered to be fine for Black, and this game doesn't challenge the evaluation. 11. c5c6 A rare move whose idea is to give back the pawn immediately in order to close the c-file. 11... b7c6  12. f1e2  12... d8a5 This move was played only once before, in a Titled Tuesday game from 2016. 13. e1g1  13... b4c3 The natural continuation and a new move. 14. b2c3 This is better than exchanging queens. 14... f6e4  15. f1c1  15... c6c5  16. c3c4  16... a8b8  17. f3e1 The idea is to play f2-f3. Gukesh said in the post-game interview that he didn't like this move. 17... a5a3 [%c_effect a3;square;a3;type;GreatFind;persistent;true] Avoiding f2-f3 and preparing ...Rb2. 18. c4d5  18... e6d5  19. c2d3  19... a3d3  20. e2d3  20... g7g5  21. d3e4  21... d5e4  22. h4g3  22... b8b7  23. f2f3  23... e4g6 The endgame is equal. 24. c1d1 This move is not a mistake, but it looks strange to remove the rook from the protection against the c-pawn advance. 24... f8c8  25. e3e4  25... c5c4 Passed pawns must be pushed. 26. e1c2  26... c4c3  27. d1d6  27... d7f8 [%c_effect f8;square;f8;type;GreatFind;persistent;true] Gukesh plays the endgame superbly and maximizes his chances. 28. a1c1  28... f7f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] Another excellent move, opening the diagonal for the bishop. 29. d6d4 [%c_effect d4;square;d4;type;Mistake;persistent;true] The turning point of the game. 29... f8e6 There are two stronger alternatives. 30. d4b4  30... b7d7 [%c_effect d7;square;d7;type;GreatFind;persistent;true] The rook invades the d-file, and White's position can no longer be saved. 31. c2e3  31... f5e4  32. f3e4
