Learn How to Swallowtail Mate: Two Knights Defense
This classical chess puzzle comes from the Italian Game, Two Knights Defense, where White’s pieces are ideally placed to exploit an exposed king. The key idea is a mating net built around king safety, with the queen and bishop coordinating to restrict escape squares. The position also shows how a pinned defender can make a seemingly active king vulnerable to a forced finish. In tactical terms, this is a clean mate in 2 based on forcing checks and limited king mobility.
