Learn How to Spot a Mate in 3: Exposed King Fork
This puzzle is a classic middlegame mating net built around an exposed king and a forcing tactical sequence. White uses a queen sacrifice to drag the defender away, then follows with a bishop check that keeps the black king boxed in. The key idea is not material count, but forcing moves: checks, captures, and threats that leave the opponent with no useful defense. Patterns like this often appear when the king’s shelter is weakened and major pieces coordinate on the same diagonal or file.
