Learn How to Win Material: Discovered Attack
This Ruy Lopez middlegame puzzle shows how a discovered attack can turn a quiet-looking position into a winning tactical sequence. The key idea is that one piece is shielding a valuable line, and once it moves, a hidden rook becomes active against a loose target. In positions like this, the tactical reward is often material rather than checkmate, especially when both rooks sit on open files and one side’s king is still vulnerable.
