Queens Gambit Declined Westphalian Variation Puzzle (Rated 1107): Win Material — Crushing Fork in the Queen's Gambit Declined

This puzzle comes from the Queen's Gambit Declined and shows how active piece placement can turn into a decisive material gain. White’s queen and knight coordinate against Black’s loose queenside pieces, while Black’s king remains stuck in the center. The key idea is a forcing check that drags the defender into an awkward response, after which the queen can win a major piece. It is a classic example of using tempo, king safety, and piece overload to convert activity into material.
