1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. e1g1  5... f8e7  6. b1c3 As far as I know, this is the first time that Carlsen has played this move. It is not as popular as 6.Re1 or 6.d3, but many strong grandmasters have tried it. 6... b7b5  7. a4b3  7... e8g8  8. d2d3  8... c6a5 [%c_effect a5;square;a5;type;Mistake;persistent;true] I wonder whether this is a sacrifice or a blunder. In any case, Black has no compensation for the pawn. 9. f3e5  9... a5b3  10. a2b3  10... b5b4  11. c3e2  11... f8e8  12. e5f3 In the normal lines in which Black sacrifices the e5-pawn, he usually already has well-developed pieces and is playing d5 quickly, something that doesn't happen here. 12... c7c5  13. e2f4  13... d7d6  14. c2c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] A good way to close the game and bury the d5-break. 14... e7f8  15. h2h3  15... a6a5  16. f1e1  16... g7g6  17. f4d5  17... f6d5  18. c4d5  18... f8g7  19. c1g5  19... f7f6  20. g5f4 White has consolidated his position and is a healthy pawn up. Firouzja, however, continues to fight. 20... g6g5  21. f4e3  21... g5g4  22. h3g4 [%c_effect g4;square;g4;type;Inaccuracy;persistent;true] This move allows counterplay for Black. 22... c8g4 The pin turns out to be unpleasant for White. 23. d1c2 Now Black can disrupt the pawn structure. 23... g4f3  24. g2f3  24... f6f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] Black has some compensation for the pawn now. 25. g1f1 The king must go to a safer place. 25... d8f6  26. a1b1  26... f5e4  27. f3e4  27... f6f3 [%c_effect f3;square;f3;type;Mistake;persistent;true] Firouzja tries to avoid White's king walk, but Carlsen's reply refutes his plan. 28. c2d1 [%c_effect d1;square;d1;type;GreatFind;persistent;true] 28... f3d1 Otherwise, the king marches to e2, but the endgame is winning for White. 29. e1d1  29... a5a4 Necessary to create some activity in the queenside. 30. b3a4  30... a8a4  31. e3f4  31... e8d8  32. b2b3  32... a4a6  33. f1e2  33... d8f8  34. f4e3  34... g7e5  35. d1d2  35... f8f7  36. d2c2  36... g8f8  37. d3d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true]
