Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the King's Gambit Declined and shows how a single tactical refutation can swing the evaluation. White is behind in material, but the position contains active pieces, loose defenders, and a pinned piece that create a forcing sequence. The key idea is to notice when a seemingly strong black piece is overextended and can be challenged by a lower-value piece, opening the way to win material and restore balance.
