Defensive Unpinning Puzzle: Unpin — Defend Tactics
An unpinning tactic changes the value of a defensive piece. A pinned defender may appear to protect an important target, but once the pin is removed or exploited, that protection collapses. In this middlegame position, White combines king pressure with an attack on a loose bishop. The key idea is to force the defender into an uncomfortable choice, then use the resulting line to win material. This is a practical example of how tactical coordination can overcome temporary threats against your own queen.
