Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the Caro-Kann Defense, Advance Variation, where tactical awareness matters more than long-term plans. White is behind in material, but the position contains a forcing idea based on a discovered attack and a pinned defender. The key is that one active piece can give check while also opening a line for another piece to hit a major target. These motifs often turn a worse position into a winning combination by forcing the opponent to recapture in a way that weakens their king and pieces.
