my idea
Force every move black can make: Block the pawn’s advance with f6->e5, bring your king diagonally up+right toward the fray until the mobile pawn promotes, and capture the resulting piece with your bishop. The only move for black is then to advance the pawn. Move your king to block its advance once more, forcing black to capture your leading pawn. Defend your remaining pawn with your king (Kf5) and black must move their king to the 8th row.
No matter if they choose Kf8, Kg8 or Kh8, capture their remaining pawn and you’re effectively at book moves for a king+pawn (+bishop) vs king endgame.
Not particularly good at chess, but was able to find a path in 17 moves. Had to play around accidentally forcing a draw which was interesting.
