1. d2d4  1... g8f6  2. c2c4  2... g7g6  3. g1f3  3... f8g7  4. e2e3 This shy move is used by some elite chess players as an Anti-Grunfeld weapon. 4... e8g8  5. f1e2  5... d7d6  6. b1c3  6... b8d7 Nepomniachtchi plays in typical King's Indian style, putting the knight on d7 and then playing e5. It can't be too bad. 7. h2h3 The game will quickly take an original course. I think Keymer's idea was to postpone castling and thus make the e5-e4 advance less pleasant for Black. 7... e7e5  8. b2b4  8... e5d4 A new move. 9. e3d4  9... d6d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] 10. e1g1 White cannot avoid the isolated pawn structure. 10... d5c4  11. e2c4  11... d7b6  12. c4b3  12... b6d5  13. c3d5  13... f6d5 Black equalized without any problems and, in practice, his position is even a little more comfortable to play. White's opening strategy clearly didn't work. But the situation is not serious either. As is known from modern chess strategy, the isolated pawn is not as bad as was formerly believed. 14. b4b5  14... a7a6  15. b5a6  15... a8a6  16. c1g5  16... d8d6  17. d1d2  17... c8e6  18. f1e1  18... c7c6 Both sides make natural moves, and the game remains balanced for a long time. 19. a1b1  19... a6a8  20. g5h6  20... f8e8  21. h6g7  21... g8g7  22. e1e5  22... h7h6  23. b1e1  23... f7f6 [%c_effect f6;square;f6;type;GreatFind;persistent;true] A curious pawn structure. It's important to remove the rook. 24. e5e4
