Duras Gambit Other Variations Puzzle (Rated 935): Spot a Discovered Attack — Tactical Refutation

This puzzle is a classic opening tactical refutation built around a discovered attack and a pinned piece. Black can exploit the exposed white king and the loose coordination of White’s queen, knight, and bishop to win material with tempo. The key idea is that one capture removes a defender while simultaneously opening a line for a rook attack. In practical classical chess, these patterns often decide the middlegame before development is complete.
