Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a tactical refutation built around king safety and loose pieces. Black’s attack works because the white king is still exposed, while key white pieces are tied up and unable to coordinate. The winning idea combines check, pressure on the queen, and a fork-like sequence that forces the defender into passive replies. It is a strong example of how a single active piece can create a decisive material gain when the opponent’s king and back rank are vulnerable.
