Four Knights Game Spanish Variation Pin Puzzle (Rated 1051): Win Material — Pin Tactic

This middlegame puzzle shows how a well-timed pin can turn active piece placement into a decisive material gain. White’s bishop creates pressure on the queen and king line, forcing the defender into a difficult choice. When the queen is overloaded and the king is vulnerable, even a short tactical sequence can win a major piece or force a winning simplification. The key idea is not brute force, but using alignment and tempo to exploit king safety.
