Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Indian Defense and shows how tactical pressure can outweigh raw material. White is under heavy strain because several pieces are tied down, and one loose enemy piece can be targeted by a bishop-based tactic. The key idea is that a seemingly natural capture can open lines, create a discovered attack, and force the opponent into a sequence where material is won while their queen and knight coordination collapses.
