Learn How to Win Material: Discovered Attack
This puzzle comes from the Caro-Kann Defense, Exchange Variation, and it shows how a discovered attack can decide a middlegame. White’s pieces are lined up so that one tactical capture opens a direct attack on an important black piece while also exposing the king to a forcing check. The key idea is not a flashy sacrifice, but accurate coordination: remove the defender, create a check, and then win material when the position becomes overloaded.
