Learn How to Win Material: Tactical Refutation
This middlegame puzzle comes from the Slav Defense and shows how a seemingly active piece can become a tactical liability. The key idea is to recognize when a loose piece, an exposed king, and a vulnerable rook line up for a forcing sequence that wins material. In classical chess, these short combinations often start with a capture that opens a file or diagonal, then continue with a forcing reply that keeps the opponent tied down.
