How Drawish Are Opposite-Coloured Bishops (part four)?

HERE is another opposite-coloured bishops ending I did not cover in Opposite Exceptions.
Black has just captured on d2 in Spanton (164 BCF) - A Trifunovic (147 BCF), Middlesex Teams 1993

Black's extra two pawns are enough to win without any particular problem.
33.Bc2 Bc1 34.b3 Kf8 35.a4
Not 35.Bxh7? g6 etc, which does not change the outcome but makes the win even easier for Black.
35...bxa4 36.bxa4 f5 37.Ke2 Ke7 38.Ba3 Ba5 39.Bd3 Bb4 40.Bxa6 Bxa5
Reducing pawns to one side of the board can give drawing opportunities, but is insufficient here.
The game finished:
41.Kf3 Kf6 42.g4 g6 43.Bd3 Kg5 44.gxf5 gxf5 45.Bc4 e5 46.Be2 Bc7 47.Kg2 h6 48.Bd1 e4 49.Be2 Kf4 50.Kf2 B6+ 51.Kg2 Ke3 52.Bb5 f4 53.Kf1 f3 54.Ke1 Ba5+ 55.Kf1 Kf4 56.Bc6 e3 57.Bb5 Ke5 58.Bd3 Kd4 59.Bb5 Kc3 0-1
