This position is a known position and it is analyzed as a draw in a book of Mark
Dvoretsky from 1992(secrets of chess tactics)

In the game black blundered and lost.
The game continued 1.Bg7+ Bf2+ 2.Kf1 Bb5+?? but Mark dvoretsky says at page 74
that black could play 1...f6 that is enough for a draw and 1..Bf2+ 2.Kf1 f6 is a
different possible move order.
