Learn How to Win Material: Discovered Attack
This puzzle is a classic middlegame example of a discovered attack in the Indian Defense. One piece can move with tempo, uncovering a stronger line of attack from a queen or bishop while also winning material. The key idea is that tactical pressure often comes from alignment: when a defended piece is pinned, overloaded, or tied to another target, a single forcing move can create a decisive material gain without needing a mating attack.
