Alapin Unpinning Chess Puzzles
Alapin Unpinning is a tactical motif where a pinned piece is freed by moving or interposing another piece so the pin no longer matters. In practice, it often appears when a bishop, knight, or rook is pinned to the king or queen and the side under pressure uses a precise move to remove the pin’s effect. The key idea is not just escaping the pin, but doing so while keeping the position tactically sound.
To spot Alapin Unpinning, look for positions where a pinned piece is defended by a second piece that can step in, capture, or create a new line of defense. It is especially useful when the pin is only temporary and the unpinning move also attacks the pinning piece or gains tempo. Use it when you can break the pin without losing material, because the motif often turns a passive defense into active counterplay.
