Learn How to Spot Swallowtail Mate: King Safety
This puzzle is a pure king-safety lesson from the Sicilian Defense, where one side’s development and piece activity create a mating net before material matters. The key idea is that an exposed king in the center can be punished immediately when the queen and bishop coordinate on the same diagonal and the escape squares are covered. Even in the opening, tactical threats can override a material deficit if the opponent’s king has no flight squares and the defending pieces are poorly placed.
