a pin where the pinned piece is the king, meaning it cannot move without putting the king in check, making it illegal to move the pinned piece
An absolute pin in chess occurs when a piece is pinned against the king, meaning the pinned piece cannot move without exposing the king to check. This makes moving the pinned piece illegal because it would place the king in danger. For example, if a rook or queen attacks a piece that is in line with the opponent's king, that piece cannot move without putting the king in check. Absolute pins are especially strong because they completely restrict the movement of the pinned piece and can force the opponent into a defensive position.
- The chess piece was under an absolute pin, unable to move without risking the king's safety.
- When the queen moved into position, it created an absolute pin on the opponent’s rook.
- The player found himself in an absolute pin, where even a small move could lead to a checkmate.
- The knight was stuck in an absolute pin, unable to move because the king was in danger.
