Learn How to Use a Discovered Attack: Decisive Material Gain
This puzzle is a classic example of a discovered attack in a sharp middlegame-to-endgame transition. One piece is forced to move with check, and that temporary clearance opens a line for another attacker to strike a valuable target. The key idea is that the checking move is not the real point; it is the hidden follow-up that wins major material. In classical chess, these tactics often appear when queens, rooks, and bishops are aligned on open files or long diagonals.
