1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. h2h4 A frequent Anti-Grunfeld line at the World Cup. 3... f8g7  4. b1c3  4... d7d6  5. e2e4  5... b8c6  6. d4d5  6... c6e5  7. f1e2  7... h7h5 Carlsen is trying to benefit from the h2-h4 move. He secures the position of his centralized knight. 8. c1f4 Fedoseev  replies with a novelty. This is his way of fighting the knight: by trading it. 8... e8g8  9. g1f3  9... e5f3  10. g2f3  10... c7c6  11. d1d2  11... c6d5  12. c4d5  12... g8h7 It is important to prevent the swap  of this bishop. It might have a bright future... 13. a2a4  13... f6d7 But since the white king has remained in the center, Black  would be happy to open the files for his pieces. 14. a4a5  14... f7f5  15. a1a3 The rook protects the f3-pawn, while at the same time it is ready to add pressure on the queenside. 15... d7e5  16. f4e3 Black has made a lot of progress and now comes with a brilliant idea. 16... f5f4 Carlsen opens the file, and this is just  the beginning. 17. e3f4 White has no choice. 17... c8d7 A neat move! Now that the development is finished, Carlsen is ready to occupy the f-file. 18. c3d1  18... f8f4 Showing a profound understanding of the position and of  the game itself. 19. d2f4  19... g7h6  20. f4g3  20... d8f8  21. d1e3  21... h6f4  22. g3g2  22... a8c8  23. a3c3  23... c8c3 Another deep decision. Carlsen has only a bishop for a  rook and a pawn but nevertheless trades more pieces? Well, the linear,  mathematical model does not work here anymore as the black blockading  bishop on f4 is worth more than the opponent's rook on h1 at the moment.  Speaking of that rook, it is completely out of the game; therefore, Black  needs to swap pieces on the queenside in order to open more room for his  queenside attack. 24. b2c3  24... f8c8  25. c3c4  25... b7b5  26. a5b6 The only move. 26... a7b6  27. g2g1 After this, Fedoseev will be completely helpless  until the end. 27... c8a8  28. e1f1  28... a8a2 Keeps all the white pieces paralyzed. 29. e3g2  29... a2a1 This is good enough. 30. g2e1
