1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... d7d6  5. e1g1  5... c8d7  6. c2c3  6... g7g6  7. d2d4  7... f8g7  8. h2h3  8... g8f6  9. a4c2  9... e8g8  10. f1e1  10... f8e8  11. b1d2  11... d8e7  12. d2f1  12... e7f8  13. f1g3  13... g7h6 A novelty. It makes sense to trade the dark-squared bishop which is often a  problematic piece in these structures. Especially if White closes the  center with d4-d5. 14. f3g5 Firouzja prevents the idea of the world champion. The position is very rich in content. A lot of moves make sense. 14... c6d8 A nice maneuver. 15. c2b3  15... d8e6  16. h3h4  16... a8d8  17. c1e3  17... h6g7  18. h4h5  18... g7h6 Carlsen is never shy to make the maximum out of any situation.  Even if this means to seemingly lose a tempo. 19. d1c1  19... f6g4  20. g5e6  Firouzja blinks first. 20... f7e6  21. e1f1  21... g4e3 Not a bad move. 22. f2e3  22... f8e7  23. h5g6  23... h7g6 The bishop pair and the possibility of play  along the dark squares determines the advantage of the world champion. 24. c1d2  24... e5d4  25. c3d4  25... g8g7  26. f1f3  26... e8f8  27. a1f1  27... f8f3  28. f1f3  28... d8f8  29. d2c3 White starts to  demonstrate activity. 29... c7c6  30. g3f1  30... e6e5  31. f3f8  31... g7f8  32. c3c4 Suddenly Firouzja has serious threats.  Carlsen does not react in the best possible way: 32... e7f6  33. d4e5  33... d6e5  34. c4b4  34... c6c5  35. b4b7 Now White keeps all his advantages:  both material and initiative. Notice how wonderful his knight is; it does  not let any black pieces around his Majesty. 35... d7b5  36. b7c8  36... f8e7  37. c8c5  37... f6d6  38. c5d6  38... e7d6  39. b3f7  39... b5f1 Now the world champion enters an endgame,  rich in drawing opportunities despite the extra white pawns. 40. g1f1  40... g6g5  41. f1e2  41... h6f8  42. e2f3  42... d6e7  43. f7c4
