Learn How to Win Material: Discovered Check
This middlegame puzzle comes from the Ruy Lopez and shows how a discovered check can force a powerful tactical sequence. White’s active knight creates immediate pressure on the black king while also uncovering attacks on key pieces. The idea is not a mating attack, but a decisive material win: the check forces a response, and the follow-up exploits a pinned or overloaded defender. In classical chess, these motifs often appear when one piece has to do two jobs at once.
