Learn How to Fork: Decisive Material Gain
This puzzle is a classic tactical fork in the middlegame, where one active knight creates a forcing check that also attacks a major piece. The key idea is that checks can be more than just king safety moves: they can also improve piece coordination and expose a hidden target. Here, Black’s knight jumps into an aggressive square, forcing the king to respond while the queen becomes vulnerable to capture. The result is a decisive material gain and a clear tactical edge.
