When the Wrong Bishop Still Wins
Win against perfect defense
Waking the engine…
The theory
The wrong bishop and rook pawn is only a draw when the defender reaches the corner. Deny that corner and the win returns.
The condition. If your king arrives in time to keep the enemy monarch away from the drawing corner, the pawn queens normally.
The method. Combine king and bishop to shoulder the defender aside, control the escape squares, and march the pawn up the board.
In this drill the engine races for the corner. Cut it off cleanly and precisely, or the theoretical draw slips back in.
