1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. b1c3  3... f8g7  4. e2e4  4... d7d6  5. h2h3  5... e8g8  6. c1e3  6... b8c6 A provocative move, in the spirit of the game Letelier-Fischer. 7. d4d5  7... c6e5  8. f2f4  8... e5d7  9. g2g4 A very unusual position arose. White has  advanced six out of his eight pawn, whereas Black has only two of them  moved, just modestly a half-move through. However, since Firouzja has  developed most of his pieces and castled he can hope to undermine the  center nicely. 9... c7c6  10. g1f3  10... c6d5  11. c4d5  11... b7b6 Black is blitzing out a novelty. Firouzja is not afraid to weaken the c6 square. 12. f3d4  12... d7c5 The point. 13. d1f3 A wise decision. It also came as a surprise for Caruana's  younger opponent. On his next two moves Black spent almost half an hour. 13... c8b7  14. g4g5  14... f6e4 But found a good continuation. There is  nothing else. If Firouzja does not use his temporary development advantage it will disappear. 15. c3e4  15... b7d5  16. e4f6  16... e7f6  17. f3d5  17... f8e8  18. d4c2  Best. 18... f6g5  19. e1c1  19... g5f4  20. e3d4 An important move. Caruana swaps  off the opponent's most dangerous piece. 20... g7d4  21. d5d4  21... c5e6  22. d4d2  22... d8f6  23. c1b1 Finally White consolidated. Technically speaking, the material slightly favors Black. However, since the pawns are not moving  easily it looks easier for the pieces to maneuver and occupy good squares.  23... a8c8  24. f1b5  24... e8d8  25. c2b4  25... d6d5 Of course! The knight should  not be allowed this fantastic outpost for free. 26. h1f1  26... c8c5  27. a2a4 Consolidating even more. 27... d5d4 Probably  Firouzja's first inaccuracy in the game. 28. b4d3  28... c5f5  29. f1f3  29... g6g5  30. d1g1  30... g8f8  31. h3h4 Caruana grasps his chance to open the enemy king. 31... h7h6  32. h4g5  32... h6g5  33. f3h3  33... f4f3  34. b5c4  34... f8e7  35. c4e6 One more precise exchange. Caruana mainly outplayed his  opponent today in the art of trading.
