Learn How to Win Material: Discovered Attack
This Ruy Lopez middlegame puzzle is a classic example of a tactical refutation based on a discovered attack and a fork. White’s pieces are coordinated around the center, while Black’s advanced knight creates a temporary threat that can be met by forcing tactics. The key idea is to look for a capture that removes the attacker and opens a line for another piece to strike a more valuable target. In positions like this, material balance can change quickly when one loose piece is overworked.
