1. e2e4  1... c7c5  2. b1c3  2... d7d6  3. f2f3 It's not the first time that the world champion  used this rare line. 3... b8c6  4. f1b5  4... g7g6  5. g1e2  5... f8g7  6. d2d4  6... c5d4  7. e2d4  7... c8d7  8. c1e3  8... g8f6  9. d1d2  9... e8g8  10. e1c1  10... a8c8  11. b5e2 Ultimately it all ended in a Dragon. White can be happy that he got his opponent out of his comfortable Najdorf zone, whereas  Vachier-Lagrave can enjoy the relatively obscure position of the enemy  light-squared bishop on e2 (it normally stands much more actively on b3)  in this double-edged position. 11... a7a6 This looks like the right plan here. White is ready to swap the black knight any time it maneuvers to c4, and in this case it would not matter if the bishop stands on b3 or e2.  However, the advance of the queenside pawns will highlight the fact that  White does not have enough control over the d5-square. 12. c1b1  12... b7b5  13. g2g4  13... c6d4  14. e3d4  14... e7e5 Forcing matters. 15. d4e3  15... b5b4  16. c3d5  This turns out to be a mistake. 16... f6d5  17. e4d5  17... e5e4 A very strong move which immediately opens the files  and the diagonals for the black pieces. 18. f3e4  18... f8e8 White cannot keep the extra pawn. 19. e3d4  19... e8e4  20. d4g7  20... g8g7  21. h2h3  21... a6a5 Vachier-Lagrave secured a large  advantage. 22. h1f1  22... d8e7 The control of the open file determines Black's advantage.  Carlsen has problems with his central pawn. 23. e2d3  23... e4e5
