Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Old Indian Defense and shows how a single forcing move can transform an active position into a winning tactical sequence. The key idea is a discovered attack: one piece steps with tempo, opening a line for another attacker and creating a direct threat against the king and major pieces. In this kind of classical chess position, the side to move can exploit loose coordination, pinned pieces, and vulnerable squares to win material decisively.
