Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the Slav Defense, Three Knights Variation, where one careless trigger move allows a tactical refutation. The key idea is removal of the defender: a piece that looks active is actually overextended and can be exchanged off to expose a more valuable target. Black’s pieces coordinate to win material while also improving king safety and piece activity, turning a balanced position into a decisive advantage.
