I think >you are looking at the wrong line... > >36.Bxe5 Bxe5 is a straight win for black Dave meant 36.Bxe5 Bxe5 and it is not clear Here is again the relevant analysis(I added * to singular moves of black that is before move 39 and I am going to look at this position more today because I have other things to do) Thanks to dave Gomboc for doing the job. I did not look at most of the analysis for 37...Bxh2+ 36.Bxe5! Bxe5* 37.Nc5! Bxh2+ 38.Kxh2 dxc5* 39.a4 Bc6* 40.Rd6 cxb3 41.Bd3 b2 42.Re1 b1Q 43.Rxb1 Rxb1 44.Bxb1 is unclear, while after 40.Re6 Kf7 41.Rde1 cxb3 42.Bd3 Bb5 43.axb5 Rxe6 44.Bc4 Rbb6 45.Bxb3 White should be able to hold the rook ending. Meanwhile, 40.Re6 Kf7 41.Rde1 Rxd7 42.b4 cxb4 43.cxb4 Rb7 44.Bd1 Rxb4 45.Bf3 Bxf3 46.Rxa6 Rb2 is wild!, I'll let someone with a faster machine handle that variation (there may be good deviations for either side along the way too). If something refutes this line, it's probably this. This leaves 36.Bxe5! Bxe5* 37.Nc5! dxc5 38.Rxe5 Rxa2* 39.bxc4 Bxc4 40.Rxc5 which looks like White should be able to grovel a draw here too. 39...Bc6 40.Rxc5 Bxg2 may be an improvement for black and I did not check this line Uri
