Queen's Gambit Declined Puzzle (Rated 988): Pin — Win Material
In this Queen's Gambit Declined middlegame, Black has extra material, but the queen and minor pieces are poorly coordinated. The key tactical idea is to exploit a king-zone entry that forces a response while exposing an overloaded queen. Once the defender is displaced, a pin and skewer combine to win material decisively. This is a classic example of how active piece placement and king safety can outweigh a temporary material deficit.
