Learn How to Win Material: Tactical Refutation
This middlegame puzzle is a classic example of a tactical refutation where an active defensive move turns the tables by winning material. The key idea is to notice when a high-value piece is overextended and can be challenged by a lower-value piece, especially when the enemy king is exposed and several pieces are tied down. In classical chess, these positions often look dangerous for the defender, but accurate calculation reveals that the attack is actually unsound.
