Learn How to Spot Swallowtail Mate: Mate in 1
This puzzle is a classic swallowtail mate pattern in the middlegame, where the defending king is boxed in by its own pieces and the final attack lands with no escape squares. The key idea is not material gain, but immediate king safety collapse: a forcing queen move creates a mating net that the opponent cannot parry. In classical chess, these motifs often appear when the king is exposed and the attacking queen has direct access to the vulnerable f-file or diagonal.
