1. d2d4  1... g8f6  2. g1f3  2... d7d5  3. c1f4  3... e7e6  4. e2e3  4... f8d6  5. b1d2  5... b7b6  6. f4g3  6... e8g8  7. f1d3  7... c8a6  The swap of the light-squared bishops is one of the safest ideas against  the London. 8. a1c1  8... a6d3 It is interesting that in this line it is White who  usually doubles the opponent's pawns after capturing on d6. 9. c2d3  9... c7c5  10. d1a4 Aronian is trying to inhibit the opponent's normal  development. 10... d6e7 Carlsen moves the bishop away from the vulnerable  position, thus preparing both Nb8-d7 and the move in the game. 11. e1g1  11... d8d7  12. a4d7 After this trade White has no advantage at all. 12... b8d7  13. c1c2  13... a7a5 In fact, Black's position is much easier to  play. He has a clear play on the queenside, and the annoying white's  bishop influence can be easily bypassed by the maneuver Ra8-a7-b7.  Speaking of the white bishop, it might soon become a problematic, empty  bishop: seemingly active, but in reality, ineffective. 14. a2a4 Probably  missing Black's next move. 14... d7b8 A nice detour. The knights are very good with such  maneuvers. They see an outpost and run towards it without worrying about  the speed. 15. f1a1 After this White's position is really bad. 15... b8c6  16. g1f1  16... f8c8 There is no rush to place the knight on the  outpost; it is not going anywhere. 17. f1e2  17... f6d7  18. d2b3 On the queenside, Carlsen achieved a lot. It is time to gain space on the opposite wing. 18... h7h5 Instructive play by the world champion! 19. h2h4 That  weakens the g4-point. 19... f7f6 Intending to lock up the bishop with e6-e5. 20. d4c5  20... b6c5  21. d3d4 Finally Aronian decided to clarify the queenside  situation but in the process opened the b-file for the black rooks. 21... c6b4  22. c2c3  22... g8f7 Carlsen is following his idea of a bishop exclusion. 23. d4c5  23... e6e5 The bishop on g3 is out of the game indefinitely, and the  black rooks own the b-file in full. 24. f3d2  24... f7e6 Obvious but not accurate here. 25. f2f4 Aronian grabs the only chance to demonstrate activity.  Otherwise, he knows he would be slowly squeezed on the queenside. 25... b4c6  26. f4e5 Now Black is in control again. 26... f6e5  27. d2f3  27... c8b8  28. a1b1 Missing the last chance to attack the d5-spot. 28... b8b4 Now it is more than obvious that Carlsen has completely  outplayed Aronian. 29. b3d2  29... b4a4 The first pawn harvest of the season. 30. e3e4  30... d5d4  31. c3c4  31... a4a2 The most natural, obvious move. And one that gave Aronian one last amazing chance. 32. b2b3  32... a8b8 Back to control. 33. e2d1  33... b8b5  34. b1c1  34... b5c5  35. c1c2  35... a2a1  36. c2c1  36... a1a2  37. c1c2  37... a2a3  38. f3g5  38... e6f6  39. g5f3  39... c5c4  40. c2c4  40... d7c5 Aronian  tries active play: 41. d1c2  41... a3a1  42. c2b2  42... a1h1  43. b3b4 But Carlsen neatly  refutes his idea: 43... c5d3  44. b2b3  44... d3b4  45. b3a4  45... f6e6  46. a4b5 And then finishes the game beautifully  with: 46... a5a4
