Zukertort Opening Black Mustang Defense Puzzle (Rated 1311): Win Material — Tactical Refutation

This puzzle is a classic middlegame example of tactical refutation in the Zukertort Opening. White’s queen activity creates immediate pressure, but the real idea is to exploit a loose enemy piece and the alignment of the black queen and knight. The position rewards accurate calculation and shows how a forcing capture can overturn material balance while simplifying into a favorable chess endgame. It is a strong example of classical chess technique: use tactics to convert initiative into a decisive material edge.
