Learn How to Spot Mate in 1: Knight Fork
This middlegame puzzle is a classic example of a forcing tactical finish built on king safety. White’s pieces coordinate around the enemy king, and the key idea is that a knight can jump to a square where it gives check while also controlling escape squares and important defenders. In positions like this, the strongest move is often not the most materialistic one, but the one that ends the game immediately by exploiting a vulnerable king and overloaded back-rank or queen-side defenses.
