Learn How to Fork: Winning Material
This middlegame puzzle is a classic example of a tactical refutation based on a fork and an overloaded defender. One well-timed check forces the king into a narrow response, and that tempo creates a second tactical hit against a high-value piece. The key idea is that the defender cannot protect everything at once, so the attacking side wins material by combining check, threat, and piece activity. These are the kinds of patterns that often decide classical chess games.
