1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... g8f6  4. d2d3  4... f8c5  5. c2c3  5... e8g8  6. e1g1  6... d7d6  7. b5a4  7... c6e7  8. a4c2 White prepares d3-d4 but does not yet show where will his  queenside knight go. 8... e7g6  9. d3d4  9... c5b6  10. a2a4  10... c7c6  11. d4e5  11... g6e5  12. f3e5  12... d6e5  13. d1d8  13... f8d8  14. a4a5  14... b6c5  15. b1d2  15... c8e6 The opening went fine for Grischuk and he enjoys comfortable  equality. Black's problem was purely psychological. As Grischuk put it he  clearly understood that this same position can be achieved with reversed  colors. Obviously he became extra confident and committed a serious  inaccuracy. 16. f1e1  16... b7b5 "Very big mistake." (Grischuk) 17. d2b3  17... e6b3 The Russian GM did not like neither of the alternatives, but it seems as this  is the real mistake. 18. c2b3  18... f6g4  19. e1e2 Now White is clearly better thanks to his bishop  pair. Carlsen quickly builds upon his advantage. 19... d8d6  20. c1g5  Wins an important tempo to bring the queenside rook out. 20... g8f8  21. a1f1  21... g4f6  22. g2g3 In order to prepare f2-f4 which will open both files  and diagonals for his pieces. Notice that Black holds the d-file but it is completely useless for his as the bishops control all the squares. In the  meanwhile Carlsen wants to open a file for his own rooks. 22... a7a6  23. g1g2  23... f6d7  24. g5c1  24... c5a7  25. f2f4  25... f7f6  26. h2h4  26... a8e8  27. h4h5  27... h7h6 Forced. 28. b3a2 One of those little moves that make a big difference at the  end. The bishop steps away from the possible tempos after Nd7-c5 and  eventually d3. 28... c6c5 "Ugly as it blocks the bishop" (Carlsen) 29. c1e3 Grischuk praised Carlsen's play after the game and especially  this decision. It was not very obvious what the pins and the counterpins  will lead to, plus White sacrifices a pawn. But the world champion had it  all right. 29... e5f4  30. g3f4  30... e8e4  31. a2b1  31... e4e7  32. f1e1  32... f6f5 Missing his chance. 33. b1f5  33... d7f6 The knight covers the e8 spot, however Black's ship is  already leaking from far too many holes. 34. g2f3  34... f6d5  35. e2d2 "A complete surprise for me." (Grischuk) 35... d6d8  36. f5e4 The pins worked in White's favor. 36... e7d7  37. e1d1  37... d5f6  38. d2d7
