Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with a pin and a trapped piece. One side has active pieces aimed at the enemy king and the b1 rook, while the defender’s coordination is loose. The key idea is that a forcing check can pull the king into a vulnerable square, allowing the attacking side to win material immediately. In classical chess, these tactical motifs often appear when rooks and bishops line up on open files and diagonals.
