Learn How to Win Material: Discovered Attack
This chess endgame puzzle shows how a single forcing move can turn active pieces into a decisive tactical sequence. The key idea is a discovered attack: one piece moves with tempo, uncovering a stronger line for another piece behind it. In classical chess, these patterns often appear when rooks are aligned on open files and the king is exposed. Here, Black’s coordination is superior, and the tactic wins material by exploiting pinned pieces and overloaded defenders.
