Learn How to Win Material: Tactical Refutation
This middlegame puzzle is a classic tactical refutation: one active piece is overextended and can be punished by forcing exchanges. The key idea is that a hanging piece on an open line can be captured, and the resulting recapture sequence wins material because the defender is overloaded. In practical classical chess, these moments often decide the game immediately, especially when king safety and piece activity are already imbalanced.
