Learn How to Spot Swallowtail Mate: Mate in 1
This middlegame puzzle is a classic example of a mating net where the enemy king is boxed in by its own pieces and pawns. The key idea is to recognize when a queen can exploit the weakened king zone, especially after the opponent’s last move creates a fatal gap. In positions like this, material count matters far less than king safety. Even in classical chess, a single forcing move can end the game immediately if the king has no escape squares and no piece can interpose.
