1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. e1g1  5... f8e7  6. f1e1  6... b7b5  7. a4b3  7... e8g8  8. a2a4  8... c8b7  9. d2d3  9... d7d6  10. c1d2 A tricky move order that deprives Black of the standard Nc6-a5 maneuver. 10... d8d7 Played after almost half an hour of reflection. Was Carlsen  trying to remember something? Or was he deciding what to reveal and what  to hide before the match? At the press conference he said \"I just did't  know it very well.\" 11. b1c3 Now the d7-square is no longer available for the kingside knight; therefore, Black switches back to 11... c6a5  12. b3a2  12... c7c5  13. c3e2  13... a5c6  14. e2g3 The knight landed on g3 via a slightly different  route, and Bacrot is ready for the usual kingside attack business. 14... d6d5 The most aggressive way. 15. e4d5  15... f6d5  16. c2c3 A novelty that was played instantly. But  judging by the amount of time spent by both the players so far, the  impression is that they both were already out of book. 16... a8d8 In Marshall spirit! 17. a4b5 It seems useful to open the a-file for the rook. However,  Carlsen delicately criticized this move, mentioning that the bishop on a2  is in big trouble in many lines afterward. 17... a6b5  18. f3e5 And  Bacrot takes the most principled decision. 18... c6e5  19. e1e5  19... e7d6  20. e5e1  20... d5f4  21. d2f4  21... d6f4 The end of the forcing line. Black has full  compensation for the pawn, thanks to his excellent bishops and control  over the d-file. 22. g3e4 Defending the pawn tactically. 22... d7c7 A clever move that provokes a kingside weakening. 23. g2g3 Bacrot voluntarily weakens the light squares, a decision he would  regret later. 23... f4e5  24. f2f4 One more weakening. 24... e5d6  25. d1h5  25... c7c6  26. h5h3  26... c5c4 \"I was already feeling very comfortable.\" (Carlsen) It is important to block the white bishop as it is always ready to do something  malicious to the enemy kingside. 27. d3d4  27... d8e8  28. d4d5  28... c6d5  29. a1d1  29... e8e4 \"I didn't see a win after the queen sac, but I thought it  would be very difficult for him.\" (Carlsen) 30. d1d5  30... e4e1  31. g1f2
