Learn How to Swallowtail Mate: Mate in 1
This puzzle is a classic mating net built around king safety, piece coordination, and a trapped enemy king. Even in a material deficit, the attacking side can win instantly when the opponent’s king has no flight squares and key defenders are overloaded. The pattern often appears in the middlegame or chess endgame when heavy pieces invade the seventh or eighth rank and the king is boxed in by its own pieces and pawns.
