Zukertort Opening Black Mustang Defense Puzzle (Rated 1456): Win Material — Discovered Attack

This puzzle shows a classic middlegame tactical refutation built around a discovered attack and a pinned piece. Black’s pressure on the center creates a concrete tactical sequence where one capture opens lines, removes a key defender, and exposes a major piece to attack. The position is not about slow maneuvering; it is about recognizing that the opponent’s last move has left a tactical vulnerability. In classical chess, these moments often decide the game by winning material and simplifying into a clearly better ending.
