It was not easy, but I managed to find something in common between these two variations. 7. c2c3  7... f8d6  8. f4g3 [%c_effect g3;square;g3;type;GreatFind;persistent;true] It's also possible to exchange and play the normal plan with Ne5-f4, but the move played in the game is more dangerous. It's hard for Black to complete development without trading bishops, but opening the h-file brings the rook to the game. 8... e8g8  9. f1d3  9... b6c7  10. g3h4 [%c_effect h4;square;h4;type;Inaccuracy;persistent;true] The plan of capturing the knight on f6 is not effective. 10... b8c6  11. h4f6  11... g7f6  12. e1g1  12... c5c4 [%c_effect c4;square;c4;type;GreatFind;persistent;true] 13. d3e2  13... f6f5 Black has controlled all of White's pawn breaks and is ready to advance the pawns on the queenside. 14. g2g3  14... b7b5  15. f3h4  15... g8h8  16. h4g2  16... f8g8  17. b2b3  17... c7a5  18. d1c2  18... g8c8  19. b3c4  19... b5c4  20. b1b7  20... c8c7  21. f1b1  21... a5a6  22. b7c7  22... d6c7  23. g2f4 The worst is over for White, who managed to stabilize the queenside and can count on equality. 23... a8b8  24. b1b8  24... c7b8  25. c2b2  25... b8d6  26. e2d1  26... h8g7 [%c_effect g7;square;g7;type;Inaccuracy;persistent;true] The king goes the wrong way, and this will lead to defeat. 27. f4h5  27... g7g6 [%c_effect g6;square;g6;type;Mistake;persistent;true] 28. h2h3 The plan is to play g3-g4, undermining the black king's defenses. 28... a6a3  29. b2c2  29... d6c7 [%c_effect c7;square;c7;type;Inaccuracy;persistent;true] played to bring the queen to the defense, but it's already too late. 30. g3g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] 30... c6e7  31. d2f3 There are other ways to win: 31... d7c8 [%c_effect c8;square;c8;type;Inaccuracy;persistent;true]
