Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack that also wins material through tactical pressure on the king and queen. One piece is pinned in a way that makes it vulnerable, while the alignment of major pieces creates a forcing sequence. The key idea is to remove the defender and open a line so a stronger piece can attack with tempo. In classical chess, these tactical motifs often decide the game before any endgame is reached.
