Pin

How This Tactic Works

A pin immobilizes a piece by threatening the more valuable piece behind it. There are two types: an absolute pin (the piece behind is the king, so the pinned piece literally cannot move legally) and a relative pin (the piece behind is valuable but not the king, so moving is legal but costly). Pins are created by bishops, rooks, and queens along diagonals, ranks, and files. Exploiting a pin — by piling up attackers on the pinned piece — is a core middlegame theme. The pinned piece often becomes overloaded and eventually lost.

How to Spot It

• →An enemy piece stands between your bishop/rook/queen and a more valuable enemy piece
• →The pinned piece is defending another key square or piece
• →You can add more attackers to the pinned piece than the opponent has defenders

Practice Tips

• →After each game, review positions where a Pin was possible — either you played it, your opponent played it, or it was missed by both sides.
• →Focus on the key signal: An enemy piece stands between your bishop/rook/queen and a more valuable enemy piece. Train your pattern recognition until you see this automatically.
• →Upload your games to chess.rodeo for free Stockfish analysis — it will highlight exactly where tactical opportunities were missed in your games.
