Learn How to Win Material: Tactical Refutation
This chess endgame puzzle is a classic example of a tactical refutation in a simplified position. White appears to have strong activity and a large material edge, but the position contains a hidden resource based on forcing play and an intermezzo. The key idea is to notice when a seemingly active rook is actually vulnerable to a direct counterstrike, especially when checks and captures can be used to change the balance immediately. In classical chess, these moments often decide the game on the spot.
