context: 1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5 Vachier-Lagrave has a playing style and opening repertoire very similar to that of Bobby Fischer. The Ruy Lopez is one of his favorite openings. 3... a7a6  4. b5a4  4... g8f6  5. e1g1  5... f8e7  6. f1e1  6... b7b5  7. a4b3  7... e8g8  8. h2h3  8... c8b7  9. d2d3  9... d7d6  10. a2a4  10... c6a5  11. b3a2  11... c7c5 This queenside expansion is a very common idea in the Ruy Lopez. 12. b1d2  12... d8c7  13. d2f1  13... b5b4  14. c1d2  14... b7c8 [%c_effect c8;square;c8;type;GreatFind;persistent;true] Carlsen also plays this important defensive move, countering a knight jump to f5. 15. f1e3  15... c8e6  16. e3f5 This move has never been played in this position (although there will be a transposition of moves later in the game). 16... a5c6  17. c2c3  17... e6a2 [%c_effect a2;square;a2;type;Inaccuracy;persistent;true] 18. a1a2  18... b4c3  19. b2c3  19... f8b8  20. d3d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] White's position is clearly better with the strong knight on f5, pressure in the center, and the possibility of exploiting the weakness of the d5-square. 20... e7f8  21. d4c5  21... d6c5  22. d2g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] Forcing the knight to go back.
