Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with a tactical refutation. One piece is acting as a shield, and once it is challenged or removed, a hidden line opens up against a more valuable target. The key idea is that active rooks and a centralized queen can create immediate pressure when a pinned or overloaded piece can no longer defend everything at once. The result is a winning sequence that turns activity into decisive material gain.
