Learn How to Fork: Decisive Material Gain
This puzzle comes from the King's Indian Defense and shows a classic middlegame tactical refutation based on a fork. Black’s active knight jump creates immediate pressure on the white king and pieces, forcing a response while also winning time. The key idea is that a forcing check can be used to expose the king and simultaneously attack valuable material. In practical play, these motifs often decide the game even when one side is already up material.
