Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a tactical refutation built around a fork and a hanging piece. Black’s active knight jumps into the center with tempo, creating a direct check while also attacking key white material. The position shows why king safety matters so much in classical chess: White’s king is exposed, pieces are loose, and one tactical shot can convert a static edge into a decisive material gain. The idea is not a long maneuver but a short forcing sequence.
