Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a tactical refutation based on a discovered attack and direct material gain. White’s central pawn can capture an advanced enemy piece, and that capture also opens a line for the queen to hit a key defender. The position is not about slow maneuvering: it is about noticing that one move changes the geometry of the board and exposes a loose piece. In practical classical chess, these moments often decide the game immediately.
