Learn How to Win Material: Discovered Check
This middlegame puzzle is a classic example of a tactical refutation built around king safety and piece activity. White’s attack works because the enemy king is exposed and several black pieces are overloaded or poorly coordinated. The key idea is to create a forcing sequence that gives check while also opening lines for a second threat, turning a simple tactical shot into a decisive material win. Patterns like discovered check, double check, and trapped-piece tactics often appear together in such positions.
