One of the white pawns will be lost  anyway, and Black will not allow any compensation. 17. f4e3  17... g7d4  18. e3d4  18... c5b3  19. a1b1  19... b3d4  20. d1d4  20... e8e2 Vachier-Lagrave  wins a pawn, but the win is not yet in sight. If White manages to swap the queenside pawns, he would be able to hold. 21. g2f3  21... e2c2  22. f3e4  22... c2c5  23. b1d1  23... g8g7  24. d4d3  24... a7a5 Sooner or later a crisis will happen in the center, and some  pawns will disappear. For the time being both sides try to improve their  situations. 25. d3d4  25... b7c6  26. b2b4  26... c5c3  27. e4d5  27... c6a4  28. d1d2  28... c3a3  29. b4a5  29... b6a5  30. h2h4 All the white pawns are properly  placed. 30... a4b5  31. d2b2  31... b5c6  32. b2d2  32... a3a4
