Opposite Coloured bishops – Part 9

Aron Kapstan recently won 2009 Manitoba Seniors Championship. Here is a game of his that I annotated for one of my older articles. He nicely outplayed a less experienced opponent in the complicated endgame.
(11) Tootoosis Harvey - Kaptsan Aron
CAN-op (2), 09.07.2000


37...Bxc3 38.b3 e6 39.Bc4 White is up two pawns and should win. 39...Kg7 40.Kc2 Bb4 41.Rd7 Kf6 Diagram


42.f5 ?! This 'tactical' shot just helps Black. 42...exf5 43.Rxf7+ Ke5 44.Kd3 ? [44.Bd3+-] 44...Rh8 Now the position becomes unclear. Black gets his own passer, which is supported by the king, rook, and bishop. To stop this pawn White sends his king. Seems to be a bit risky, does not it? 45.Rb7 Rxh3+ 46.Ke2 Bc3 Diagram


47.a5 !? White keeps finding tactical resources... 47...Ke4 [47...Bxa5 48.Rb5+] 48.a6 Rh2+ 49.Kf1 Diagram


49...f4 ? I think that Black is playing just using his intuition in this entire endgame. [49...Kf3 !? More precise was 50.Bd5+ Kg3 51.Rb8 (51.a7 ? 51...Rf2+ 52.Kg1 Rf4 -5.50) 51...Rf2+ 52.Kg1 Bd4 53.Rg8+ Kh3 and Black seems to be getting a draw: 54.Bc4 Rg2+ 55.Kf1 Rxg8 56.Bxg8 Kg3 57.Ke2 Kf4 0.00] 50.Rd7 f3 Diagram


51.a7 ?? Missing something very important... [51.Bd5+ White had some winning chances after 51...Ke3 52.Re7+ Kd3 53.Bxf3 Bd4 54.Be4+ (54.a7 ? 54...Rf2+ 55.Ke1 Rxf3-/+ !) 54...Kc3 55.Bd5 Ra2 56.Rc7+] 51...Rh1+ 52.Kf2 Be1# Diagram
