Editing Pin (chess) (section)

== Pin combinations ==
Pinning can also be used in combination with other tactics.  For example, a piece can be pinned to prevent it from moving to attack, or a defending piece can be pinned as part of tactic [[Undermining (chess)|undermining]] an opponent's defense. Another tactic which takes advantage of a pin can be called ''working the pin''.  In this tactic, other pieces from the pinning piece's side attack the opposing pinned piece.  Since the pinned piece cannot move out of the line of attack, the player whose piece is pinned may move other pieces to defend the pinned piece, but the pinning player may yet attack with even more pieces, etc. Using a [[Battery (chess)|battery]] of doubled rooks with a queen behind them to this end is known as [[Alekhine's gun]].

A pinned piece can usually no longer be counted on as a defender of another friendly piece or as an attacker of an opposing piece (unless the subject is still within the pinning line). However, a pinned piece can still give check to the opposing king, and therefore can still defend friendly pieces against captures made by the enemy king.
