That allows a forced win.
1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. d2d4  3... c5d4  4. f3d4  4... g8f6  5. b1c3  5... d7d6 The Classical line  is a rare choice in the practice of the world champion. 6. c1g5  6... c8d7  7. d1d2  7... a7a6  8. e1c1  8... e7e6  9. f2f4  9... f8e7  10. d4f3  10... b7b5  11. g5f6  11... g7f6 A typical pawn structure arose. Both black  flanks have been weakened. However, the four black pawns in the center  look like a strong shield in front of their king. Still, they are not  ideal and have a soft spot: the e6 one. If White manages to destroy that  pawn or force it to move, all the light squares in the center will fall  into the first player's hands. 12. c1b1  12... d8b6  13. f4f5  13... e8c8 The king is not  perfectly safe here either, but Black can at least connect his rooks. 14. f1d3  14... c8b8  15. c3e2 A typical maneuver. The knight is transfered to the  f4-square. 15... d7c8 In the confession box Carlsen said that he had  done everything wrong so far, but as long as his bishop pair is on the  board, he can hope for the best. This is what his coach Simen Agdestein  had taught him. 16. e2f4  16... c6e5  17. d3e2 Now Nf3-d4 is a deadly positional  threat. Carlsen needs to hurry with the counterplay. 17... d6d5  18. e4d5  18... e6f5 A surprising choice. The black kingside pawns are now  practically dead, but the bishops gain more scope. These sudden changes in the strategic/dynamic balances are some of the world champion's main  weapons. 19. f3d4  19... e7c5  20. h1f1  20... h8e8  21. a2a3  21... b8a8 Sidestepping the possible checks.  From a positional perspective, Black's position is hopeless. However, his  position keeps a massive amount of hidden dynamical chances which Tari  failed to appreciate. 22. h2h3  22... c8d7  23. f4h5 For a moment White loses control, and that is all Carlsen needs. 23... e5c4  24. e2c4  24... b5c4 It all starts to make sense for Carlsen now  that he has managed to open the files and the diagonals for his pieces. 25. d2c3 Now things are getting even worse. 25... d8b8 The strong threat is Re8-e3! 26. f1f3 An obvious defense,  which however, has a non-obvious flaw... 26... e8e1 A stunning move! The white rook is overloaded. 27. d1e1  27... c5d4  28. c3b4  28... b6c7 Discovering the rook with tempo. 29. d5d6  29... c7c6  30. b4a5  30... d4b2  31. b1a2  31... b2e5  32. e1b1  32... b8b1  33. a2b1  33... c6d6 With the white king wide open,  Carlsen is no longer in a rush. 34. b1c1  34... d6d4  35. a5a6  35... a8b8
