Bg4?! This is a waste of time as Nd4-e2 and h2-h3 are useful for White anyway.
12. Nd5 Better was 12.b3 Rb8 13.Bb2.
17. Nd4 Of course, White does not blunder with 17.b3? Bxh3.
18. cxb4 After 18.Qe2 bxc3 19.bxc3 Qc7 Black's chances are preferable, but White had a try 18.f4 Nc4 19.Qe2. I planned to meet it with 19. ..Nxb2!?.
22.Rc1! Qc7 23.Bc3 Ra2 24.Rb1!? was worth considering. Perhaps Black should try 22...Nd3!?.
24. g4? This move badly weakens White's king. Better was 24.c7. Black has to play 24...Rb5 25.Qxb5! Nf3+ 26.Bxf3 Qxb5 27.Rfb1 Qc4 28.Rc1 Qd3 29.Rab1! Qxf3 30.Rb8 Qf5 31.Rxf8+ Bxf8 32.c8Q Qxa5, with a draw.
25. c7? Now this pawn advance loses. White had to play 25.Qe4, although after 25...Qxe4 26.Bxe4 e6 27.c7 d5 Black is clearly better.
27. Qxe5 Or 27.Rfc1 Qxf2+ 28.Kh1 Qh4+ 29.Kg1 Bh2+ 30.Kh1 Bf4+ 31.Kg1 Be3+ 32.Kf1 Qf2#.
