Black to play - White wins

1...Bg7 2.Kg4 Fine gives a note with 2.Rb5 Bd4 3.Kh6 Ng8+ 4.Kh7 Nf6+ with question marks to White's last two moves and a double exclam to the knight check, but White still wins by reversing his path with 5.Kh6! (instead of Fine's 5.gxf6?) 2...Bc3 3.Rb3 Again Fine gives a question mark to White and an exclam to Black for the inefficient 3.Kf3 Bd2 when again White can win by starting over with 4.Kg4! 3...Bg7 4.Kf4 Bh8 5.Ke4 Bg7 6.Rb6 Bc3 7.f6? instead White should slowly win with 7.Rb7. White should aim to advance f6 in a position where Bxf6 can be met with a pin on the f-file, for example 7...Bg7 8.Rc7 Bb2 9.Rc2 Bg7 10.f6 Bxf6 11.Rf2! 7...Bd2! instead of Fine's 7...Ng6? Black wins both pawns for a piece with a drawn ending after 8.fxe7 Bxg5! 9.Kf5 Bxe7 10.Rb7 Kf8! 11.Ke6 Bg5
