Learn How to Win Material: Tactical Refutation
This middlegame puzzle is a classic example of a tactical refutation based on piece activity and king safety. White can exploit loose black bishops and the exposed black king to win material with a forcing sequence. The key idea is to notice that one bishop move creates check while also attacking an undefended piece, turning a simple-looking position into a decisive advantage. In classical chess, these moments often come from active bishops and poor coordination.
