Learn How to Win Material: Tactical Refutation
This puzzle is a classic middlegame tactical refutation where one careless move allows a sharp response that wins material and exposes the king. The key idea is to notice loose pieces, especially a hanging knight and a vulnerable king-side structure. In positions like this, the best move is often not a quiet improving move, but a forcing capture that opens lines and creates immediate threats. Strong calculation matters more than long-term planning here.
