Learn How to Win Material: Discovered Attack
This puzzle comes from the Zukertort Opening, specifically a Tennison Gambit structure, where development and piece activity matter more than static material. The key idea is a tactical refutation that uses a discovered attack to win material while also exploiting a pinned piece. In the opening, active minor pieces can create immediate threats against loose enemy pieces, especially when one defender is overloaded or a knight is sitting on a vulnerable square. Recognizing these patterns is essential in classical chess and middlegame tactics.
