Learn How to Win Material: Discovered Attack
This puzzle is a classic middlegame tactical refutation built around a discovered attack and a forcing sequence that wins material. White can use a pawn capture to open lines, creating pressure on a pinned black bishop and the rook behind it. The key idea is that one move changes the whole board: a hidden rook attack becomes active, and Black’s pieces are overloaded. The result is a clean tactical gain rather than a speculative attack.
