Black is winning, according to Stockfish12; Komodo11.01 gives Black a slight edge at first, but eventually changes to giving Black the upper hand.
33...Bxg2 34.Kb4 Kc6 35.Kc4 a6 36.a3!?
The engines do not like this, preferring 36.Be1, but I cannot work out what is wrong with the text.
36...e5 37.Bg3
The engines prefer retreating with 37.Kd3!? but it is hard to see what that achieves.
37...Bf1+ 38.Kc3 Kd5 39.Kd2 Ke4 40.Ke1 Bh3 41.Ke2 Bg4+ 42.Kf2 f5
The problem for White is Black will get a pair of connected passers while White cannot successfully activate his queenside pawn-majority.
43.h4 f4 44.exf4
If 44.Bh2 then 44...Be6 45.b4 g4.
The game finished:
44...gxf4 45.Bh2 Bd1 46.b4 Ba4 47.Bg1 Kf5 48.Kg2 Bc6+ 49.Kf1 e4 50.Bf2 e3 51.Be1 f3 52.Bc3 f2 0-1
