Learn How to Spot Mate in 1: Queen Sac
This middlegame puzzle is a classic example of a forcing tactical finish in the Four Knights Game. White’s queen is active near the enemy king, and Black’s back rank and king safety are both badly compromised. The key idea is to recognize when a seemingly loose piece can be used to deliver immediate checkmate because the king has no safe flight squares and the surrounding defenders are overloaded or pinned. In these positions, material count matters less than the final mating net.
