Learn How to Win Material: Discovered Attack
This chess endgame puzzle centers on a discovered attack: one piece moves with tempo, uncovering a stronger line of force behind it. The key idea is that a pinned or overloaded defender can’t respond to both threats at once, so the position collapses into a winning sequence. In classical chess, these tactical shots often appear when rooks and minor pieces are aligned on open files and the king is exposed to direct checks or material loss.
