Learn How to Win a Piece: Tactical Refutation
This middlegame puzzle is about recognizing a tactical refutation when a pinned piece is overloaded. Black’s bishop creates pressure on the king side, but that pressure can be met by a forcing capture that removes the attacker and wins material. The key idea is that a piece defending another piece can become tactically vulnerable when it is pinned or tied to a stronger threat. In practical classical chess, these moments often decide the game immediately.
