Learn How to Win Material: Discovered Attack
This middlegame puzzle shows how a forcing check can expose a hidden tactical idea. White’s active rook and queen coordination create a direct threat against the black king while also uncovering pressure on a loose queen. The key lesson is that a checking move can do more than attack the king: it can force a capture, remove a defender, and open a line for a stronger follow-up. In classical chess, these tactical refutations often decide the game immediately.
