If Black advances the pawn to h4, White plays g4. If Black plays g4, White goes h4. 17... d8f8  18. g1g2 [%c_effect g2;square;g2;type;Inaccuracy;persistent;true] 18... g5g4 [%c_effect g4;square;g4;type;GreatFind;persistent;true] 19. h3h4  19... f6f3  20. d1f3  20... f8f3  21. f1d1  21... d6d5 White has to be careful in the endgame, since Black's rook is very powerful on f3 and can help with attacking the pawns on the third rank. 22. c1e3 [%c_effect e3;square;e3;type;Mistake;persistent;true] 22... d5d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] 23. c3d4  23... e5d4  24. e3f4 This is played in order to deny Black's knight the e5-square. 24... e6e5  25. f4g5 Let's not forget this is a blitz game and it's impossible to work out such details like whether Black should avoid the exchange of the bishop for the knight or not. 25... c6d8  26. g5d8  26... h8d8
