Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Old Indian Defense and shows how a single tactical trigger can collapse a position. White’s setup looks active, but the king’s safety and piece coordination are fragile. Black can exploit the fact that one pawn move opens lines for a rook and creates a discovered attack against key white pieces. The idea is not just to win a pawn, but to use the opened file and tactical pressure to gain a decisive advantage.
