Back then it was a totally  new concept. 15. h2h4  15... f6e4  16. e2e3  16... a8c8  17. a4b6 Aronian improves the opponent's pawn  structure but gets the bishop pair in return. 17... a7b6  18. c2d1 It  seems as the h5 thrust backfired. 18... d7f5 Carlsen decides to  sacrifice the pawn. 19. d1h5  19... d8d7  20. h5d1  20... c6c5 Surprisingly enough, Black's compensation exists. He has a strong center and freedom in maneuvering. The extra pawn is not  very important yet. 21. f1e1  21... c8d8  22. a1c1  22... f5h3  23. d1f3  23... f7f6 Blunting the other bishop. 24. g2h3  24... d7h3  25. c1d1  25... b6b5 Carlsen's play is instructive as usual. Every move that he  makes improves a bit something in his camp. 26. f3g2  26... h3e6  27. f2f3 Aronian  decides that the time for concrete actions came. However, in the process  he is also weakening his king. 27... e4d6  28. g3g4  28... d5d4 The central  break does not require explanation. 29. g2d2  29... e6d5  30. e3d4  30... c5c4 Play for  blockade. The content this game reminds me of another encounter between  the two opponents: the one at the London Chess Classic in 2017. Back then  Carlsen sacrificed two pawns as well, but the major difference was the  lack of queens in the game in England's capital. With the queens on, the  Norwegian has all the reasons to play for a win. 31. b2a3 Aronian must have missed something. 31... d5f3  32. d2g2  32... e8e1  33. d1e1  33... f3c3 A tempo move which provides  the necessary time for the world champion to fulfil his plans on the  queenside.
