Learn How to Win Material: Discovered Attack
This puzzle is a classic example of a discovered attack in the middlegame, where one tactical blow opens lines against the enemy king and queen at the same time. The key idea is that a forcing capture can remove a defender and expose a hidden attack on the back rank or king zone. In positions like this, the side to move often wins material by creating check first, then using the exposed queen and pinned pieces to keep the initiative.
