context: 1. e2e4  1... c7c5  2. g1f3  2... b8c6  3. f1b5 The Rossolimo line is a frequent guest at the top level. GM Sveshnikov once considered it the only way to fight against his beloved defense. 3... g7g6  4. e1g1  4... f8g7  5. f1e1  5... e7e5  6. b5c6  6... d7c6  7. d2d3  7... d8e7  8. a2a4  8... g8f6  9. a4a5  9... e8g8  10. c1e3  10... f8d8  11. d1c1  11... c5c4 Mamedov's idea from before, except that this time this is not even a sacrifice. It is a novelty, though. 12. a1a3  12... c4d3  13. c2d3 And the players enter a reversed Najdorf pawn structure. 13... f6h5 Quite a natural move. 14. e3g5 White is trying to provoke a concession. 14... g7f6  15. g5f6 Nepomniachtchi is happy to deprive his opponent of his bishop pair. 15... e7f6 But now this queen becomes annoying. Carlsen has managed to equalize comfortably. 16. c1c3  16... d8e8  17. b1d2  17... c8g4  18. h2h3  18... g4f3  19. d2f3  19... h5f4 The play of both players is pretty logical and straightforward. 20. g1h2  20... a8d8  21. e1e3 The best way to defend the pawn is from the third rank. 21... b7b6 The most logical human move. 22. a5b6 The a-file is in White's hands. 22... a7b6  23. b2b4
