Learn How to Spot Swallowtail Mate: King Safety
This puzzle is a classic example of how king safety can outweigh material in the opening. Even when one side appears to be doing fine structurally, a poorly sheltered king and loose coordination can create an immediate mating net. The key idea is to look for direct access to the enemy king, especially when the queen can invade with tempo and the surrounding pieces cannot help. In classical chess, these tactical shots often arise from neglected development and exposed dark squares.
