There's no sac on h3, and White intends to get the knight to f5. 15... e5d4 This plan worsens Black's position. 16. c3d4  16... d6d5  17. e4e5 The knight on f4 is in a precarious situation. Black follows the natural plan, opening the f-file, but Antipov finds a convincing refutation. 17... f7f6  18. g3h5 A crushing move. 18... f4h5  19. c2g6  19... e6f7 The only way to save the knight, although only temporarily. 20. g6f7  20... f8f7  21. e5e6  21... f7e7  22. f3h4  22... d8e8  23. h4f5  23... e7e6  24. e1e6  24... e8e6  25. d1h5 It's over. White is a piece up, and the attack continues. 25... e6e1  26. g1h2  26... a8d8  27. f5h6  27... g7h6  28. h5g6  28... g8h8  29. g6h6  29... h8g8
