White is winning, according to Stockfish12; has the upper hand (+1.17), according to Komodo11.01.

28...Bd4 29.f4 Bxb2 30.a4

Black has levelled material, but now both engines give White's position as winning.

30...Kf7 31.Kf3 Kd7

The engines give 31...h5!? 32.Ke4 h4 33.gxh4 gxh4, but reckon White's connected passed pawns and more-central king add up to a winning advantage.

32.Ke4 gxf4

32...h6 33.f5.

33.gxf4 a6 34.Be2 Ke7 35.f5 Ba3 36.f6+ Kf8 37.a5 Bb2

Or 37...Bb4 38.e6 Bxa5 39.e7+ Ke8 40.Bh5+ etc.

38.Kf5 Bc3 39.e6 bb4 40.Bf3 1-0
