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  24. d2f2  24... e5d5 The pawn is won, the centralization kept. Black is on his  way to the win. 25. d1e1  25... d5e5  26. f2d4  26... c8c5  27. e1e4  27... d7e6  28. b2b3  28... g7g8  29. f1e1  29... e5e4 This allows White an extra possibility. 30. e1e4  30... e7c7  31. h3h4 Which Carlsen misses. 31... c5e5  32. g4g5  32... e5e4  33. d4e4  33... c7c5  34. e4a8  34... g8g7  35. a8f3  35... c5g1  36. b1b2  36... g1d4  37. b2b1  37... h7h5  38. f3f1  38... e6d5 Now after one final centralization, Vachier-Lagrave finishes  the game nicely. 39. f1e1  39... g7f8  40. e1g3  40... f8e7  41. g3e1  41... d5e6  42. e1h1  42... e6d5  43. h1e1  43... d4e5  44. e1f2  44... d5e6  45. f2f1  45... e6f5 The decisive trade. It seems ugly to  double pawns like this, but provided that the front-runner will be a  queen, the aesthetic pain can be accepted.
