Alekhine's Defense Unpinning Chess Puzzles
Alekhine's Defense Unpinning is a tactical motif in the Alekhine Defense where a pinned piece is moved or exchanged so the line of attack is opened again. It often appears after 1.e4 Nf6, when White gains space and Black later uses a pawn break or piece maneuver to free a knight or bishop that was tied to a defender. The defining feature is the removal of a pin on a piece that was restricting the position.
Look for it when one of your pieces is pinned to the king, queen, or a key defender and you can force that piece to move with a tempo, capture, or discovered attack. In practical play, the idea is to unpin at the right moment so the freed piece can recapture, defend, or counterattack in the center. In Alekhine structures, this often means using ...e6, ...d6, or a tactical exchange to break White's pressure and restore piece activity.
Frequently Asked Questions: Alekhine's Defense Unpinning
