Learn How to Win Material: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with king safety pressure. One piece is pinned or overloaded, so moving the attacking piece can reveal a stronger line against the enemy queen and king zone. The key idea is not a flashy sacrifice for its own sake, but forcing the opponent into a sequence where a defender is removed and a major piece becomes vulnerable. These are the kinds of tactical patterns that often decide classical chess games.
