Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a tactical fork creating a decisive material gain. Black’s active knight jumps into the white king zone with tempo, attacking multiple high-value pieces at once and forcing the king to respond. The position is especially instructive because White’s king safety is already compromised, so a single forcing move turns activity into concrete profit. In classical chess, these patterns often decide games before any endgame is reached.
