Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with a tactical refutation. Black’s pieces are coordinated around the enemy king and queen, and one active rook creates a direct threat that forces White into a losing sequence. The key idea is that a seemingly natural capture can uncover a stronger attack on a more valuable target. In classical chess, these motifs often decide the game by winning material and collapsing the opponent’s coordination.
