1. e2e4  1... c7c5  2. g1f3  2... d7d6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... a7a6  6. h2h3  6... b8c6 A move that deviates from the typical choice of Najdorf players, who are certainly more attracted to 6...e5 or 6...e6, but which is still perfectly possible, as is 6...g6. 7. c1e3  7... e7e5  8. d4b3  8... c8e6  9. d1f3 This square doesn't seem the most comfortable for the queen and the reader may wonder why this piece doesn't go to d2. As is often the case, calculation provides the answer. With the queen on d2 the move 9...d5 is much more attractive for Black. 9... c6b4  10. e1c1  10... a8c8  11. c1b1 [%c_effect b1;square;b1;type;GreatFind;persistent;true] Once again the principle \"if in doubt, play Kb1\" shows its value. 11... d8c7 We're approaching the critical moment of the game and here I would like to address a typical myth that exists about the games of elite grandmasters, that is, that they know everything in the opening. Judging by the time spent and also by Vidit's comments after the game, both players were already out of preparation, even though the position was tactical, with natural moves that are also suggested by the computer and several games by strong grandmasters. This demonstrates once again, for those who still doubt it, that what wins games even at this level is skill on the board and not memory. 12. a2a3 This move invites big complications, as Black is forced to sacrifice the knight. 12... b4c2 [%c_effect c2;square;c2;type;GreatFind;persistent;true] The only way to justify the previous play. 13. b1c2  13... c7c6 [%c_effect c6;square;c6;type;GreatFind;persistent;true] Attacking the pawn on e4 and also preparing Qa4. 14. b3d2 [%c_effect d2;square;d2;type;GreatFind;persistent;true] 14... c6a4 [%c_effect a4;square;a4;type;Mistake;persistent;true] A theoretical novelty and the decisive error of the game. 14...d5 is a practically automatic move and without a doubt Firouzja would have played it in a blitz game. The move played is refuted in more than one way: in addition to what Vidit did, 15.b3 also gives White a big advantage. 15. c2d3 [%c_effect d3;square;d3;type;GreatFind;persistent;true] The best reply. 15... c8c3 There's no turning back. Black has to try to open the king position. 16. b2c3  16... d6d5  17. d3e2 [%c_effect e2;square;e2;type;GreatFind;persistent;true] Vidit prepares to hide the king on e1. After the game he admitted that he was not sure of the evaluation here (the computer considers White's position to be winning), but he played with excellent accuracy in a complicated position. 17... d5e4  18. f3g3  18... f6d7  19. e2e1  19... f7f5  20. f1e2 The good thing about having more material is that you can return some of it and still stay ahead in the count. 20... g7g6  21. h3h4  21... f8e7  22. e3g5  22... f5f4  23. g5f4  23... e5f4  24. g3f4  24... h8f8  25. f4e4
