Learn How to Win Material: Discovered Attack
This middlegame puzzle shows how a forcing tactical sequence can turn king safety into a decisive material win. Black’s pieces are coordinated around the white king, with a pinned defender and a vulnerable rook on the h4-square. The key idea is a discovered attack: by moving one piece with tempo, another attacker becomes stronger and the position collapses. It’s a classic example of tactical refutation in classical chess, where active pieces outweigh raw material.
