I think that succeeded fairly well." (Carlsen) 7... h7h6  Asking the bishop to chose a side. 8. g5e3 Carlsen decided to switch back to the English Attack. The only  difference in comparison to the main lines is the presence of the black  pawn on h6. It is indeed an extra tempo for the second player, but it may  quickly turn into liability in case that black castles there and opposite  pawn storms take place. 8... b7b5  9. a2a3  9... b8d7  10. d1d2  10... c8b7  11. e1c1  11... h6h5 "Let's go back to something I know. Evidently I lost my tempo up. " (Vachier-Lagrave) 12. c1b1  12... f8e7  13. d2e1  13... a8c8 Since Black does not want to castle into an attack, it is all about the d6-d5 break now. 14. h1g1  14... d8c7  15. g2g3 "I missed this idea." (Vachier-Lagrave) 15... d7e5  The first critical moment of the game. 16. g1g2 "I saw this idea. The rook is useful immediately, covering the c2 pawn." (Vachier-Lagrave) 16... e8g8  17. h2h3  17... d6d5 Mission accomplished.  Black starts his own play before the kingside is opened. 18. f3f4  18... e5c4  19. e4e5  19... c4e3 "I thought it is important I can get his dark-squared bishop."  (Vachier-Lagrave) 20. e1e3
