1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4 The Italian is the new Ruy Lopez in complexity and a chance to play for a win nowadays. 3... f8c5  4. d2d3  4... g8f6  5. e1g1  5... d7d6  6. c2c3  6... e8g8  7. h2h3  7... h7h6  8. f1e1  8... a7a6  9. a2a4 9.Nbd2 is the topical line these days. 9... a6a5 \"He surprised me [with this move], of course. I knew the move, but there are better tries for Black\" (Firouzja). So spent his rest day well and as we shall see got more than he could have dreamt for from the opening. 10. b1d2  10... c8e6  11. b2b3  11... f8e8  12. c1b2 A top novelty, but most likely we shall not see it too often... In hindsight, White regretted playing this, and felt that he should have played better. 12... d6d5 Forcing an immediate resolution in the center. That is Black's key resource. 13. c4b5  13... d5e4  14. d3e4 Only this is the real mistake. 14... f6h5 \"I completely underestimated this move. I felt kind of stupid, as it is an only move. If he backs up, he is worse. Then I felt I should hold here, but with very precise play.\" (Firouzja) 15. d2c4 Played after a bit more than five minutes on the clock. It seems as Firouzja did not yet feel how bad the situation is. 15... d8f6 So does not back up and launches a decisive attack. 16. b5c6  16... b7c6  17. c4e5  17... e6h3 Not bad at all, but that was the first moment when the inclusion of the reserves could have settled the game at once. 18. e5d3 The knight are covering a lot of squares, but will this be enough $2 18... f6g6 The second most obvious move throws away the largest chunk of the attack. 19. f3h4  19... g6g5  20. d3c5  20... g5h4 Missing his last chance for an advantage. 21. g2h3 A lot of pieces have been swapped and White does not risk to be mated anymore. On the other hand, the possibility of an ugly endgame (for Black) with a strong bishop versus a poor knight starts to frighten the second player. 21... h4g5  22. d1g4  22... g5c5  23. c3c4 \"Here I felt it is getting very tricky for him.\" (Firouzja) 23... a8b8 \"I thought this is correct, actually.\" (Firouzja) 24. e4e5  24... g7g6 \"This is really bad. When he played it, I thought for about one minute and then I saw... \" 25. b2a3 The black queen is removed from the kingside and this is suddenly deadly for the second player. 25... c5b6  26. e5e6  26... c6c5 Trying to block the bishop, but in vain. 27. e6f7  27... g8f7  28. g4d7  28... f7f8  29. d7d5  29... f8g7  30. a3c5 White wins a bunch of pawns and the game. 30... h5f6  31. c5b6
