Learn How to Spot a Mate in 1: Knight Fork
This middlegame puzzle is a classic example of a forcing tactical finish built around king safety. White’s pieces are already aimed at the enemy king, and the key idea is to notice how a knight can jump into a square that both checks the king and removes every escape route. In positions like this, material balance matters far less than the immediate mating net. The lesson is to always scan for forcing moves first, especially when the opponent’s king is exposed and their defenders are overloaded.
