Learn How to Win Material: Discovered Attack
This middlegame puzzle is built around a classic discovered attack: one active piece moves away to reveal a stronger line for a rook behind it. The key idea is that the hidden rook suddenly attacks a vulnerable target on the same file, while the moving piece also creates a direct tactical win. Because the opponent’s pieces are loosely coordinated, the tactic wins material cleanly and leaves White with a decisive advantage. It is a great example of how active rooks and piece coordination can punish an exposed position.
