Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic discovered attack idea: one piece moves with tempo, uncovering a stronger line of fire behind it. The key is that the first tactical shot is not the final goal; it is the move that opens the file or diagonal for a rook or bishop to attack a more valuable target. In positions like this, forcing moves often win material because the opponent is overloaded and cannot defend everything at once.
