Carlsen usually finds his own ways to play the openings, most of the time avoiding variations that are too theoretical. Everybody recognizes his brilliant play, especially in the endgame, but I think his legacy in opening theory is no less important and usually underrated. 5... d7d6 Certainly not the way to challenge, theoretically speaking, white's previous move. Abdusattorov makes a practical choice to accept a hedgehog pawn structure. 6. c2c4  6... f8e7  7. b1c3  7... a7a6  8. c1e3  8... e8g8  9. e1g1  9... b7b6  10. f2f4  10... d8c7  11. a1c1  11... b8d7 Black's position became very passive and one might think that White has a comfortable position, but actually it's already winning after Carlsen's next move. 12. g2g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] 12... d7c5  13. d3b1  13... c8b7  14. d1f3
