Learn How to Win Material: Discovered Attack
This middlegame puzzle is built around a discovered attack, where one move opens a line for a stronger piece while also creating a direct tactical threat. The key idea is that the attacked piece is not the real target; instead, the hidden line behind it is what matters. In positions like this, a queen, bishop, or rook can suddenly become active against the king or a loose piece, turning a small initiative into a decisive material gain.
