Queen's Gambit Declined Marshall Defense Puzzle (Rated 1431): Win Material — Tactical Refutation

This middlegame puzzle is all about tactical refutation through a forcing exchange sequence. White’s active queen and rook coordination create immediate pressure on the enemy king zone and key back-rank squares. The position is not about a long strategic squeeze; it is about recognizing when a high-value piece can be traded off in a way that leaves the opponent’s pieces overloaded and their defense collapsing. Once the first forcing move lands, the follow-up is straightforward because the remaining defenders are tied up.
