Queen's Gambit Declined Marshall Defense Puzzle (Rated 1105): Win Material — Tactical Skewer

This middlegame puzzle is about converting activity into a decisive material gain. White’s pieces are active, the knight on d5 is a key outpost, and Black’s coordination is loose enough for a forcing tactical sequence. The critical idea is to use a capture that opens lines and overloads the defender, creating a skewer-like effect on the central pieces. Once the first exchange lands, the follow-up wins a major piece by exploiting the pinned and hanging targets.
