| − | A player creates a '''pin''' when makes he attacks an opponent's piece in between his attacking piece and another more valuable enemy piece. The opponent cannot move the attacked piece without losing the more valuable piece behind it, thus effectively "pinning" the piece. Pinning pieces to the enemy King are most effective because the pinned piece ''cannot'' legally move; if it could, the King would be exposed to check. | + | A player creates a '''pin''' when makes he attacks an opponent's piece in between his attacking piece and another more valuable enemy piece.
