Opposite Exceptions (part 14)

White has just captured on f2 in Spanton (1881) - Raj Bhopal (1931), Northumbria Challengers (Newcastle) 2019. Who stands better, and by how much?

Black has the upper hand, according to Stockfish12; a slight edge, according to Komodo11.01.
61...Bxh2 62.Ke3 Bd6?!
Activating the king with 62...Kf6 seems better.
63.a5?!
The engines prefer 63.Kd4.
63...h5?
Much better is 63...Bc5+ (winning, according to Stockfish12, although Komodo11.01 gives Black just a slight edge).
64.Bf1?
64.Kd4 wins, eg 64...g5 65.a6 Bb8 66.Kc5 g4 67.Kc6! etc.
64...Kf6?
64...Bc5+ draws.
65.Ke4?
Again Kd4 wins.
65...Ke7 66.a6 Bb8 67.b4?
67.f4 seems to  hold.
67...Ba7?
There is no need for this. Black wins with 67...f5+ followed by ...g5 etc.
68.b5?
Again f4 seems to hold.
68...Kd6!?
68...g5 wins. The text probably does too, but is less clear.
69.Kf4
Or 69.f4 f5+ 70.Kf3, when 70...e5 seems strong.
The game finished:
69...f6 70.Ke4 g5 71.Bc4 f5+ 72.Kd3 h4 73.Ke2 e5 74.Bd3 Ke6 75.Bc4+ Kf6 76.Bd5 g4 77.Kf1 h3 78.fxg4 fxg4 79.Bb7 Kg5 80.Bc8 Kf4 81.Bd7 e4 82.Be6 Kf3 0-1
