Queen's Indian Use The Pin Chess Puzzles

Queen's Indian Use the Pin is a tactical motif in the Queen's Indian Defense where Black or White uses a pin to restrict a key defender and gain pressure on the center or queenside. A defining feature is the bishop pinning a knight or bishop on a file, diagonal, or against the queen, often after moves like ...Bb4 or ...Ba6 in Queen's Indian structures. The pin helps win time, weaken pawn support, or set up a favorable exchange.
