Learn How to Fork: Decisive Material Gain
This middlegame puzzle is a classic example of a forcing tactical refutation built around a knight fork. Black’s active knight jumps into the white king’s zone, creating a direct check while also attacking a valuable bishop. The key idea is that the king’s limited escape squares make the check especially strong, and the follow-up wins material immediately. In practical classical chess, these are the moments where king safety outweighs static material count.
