Learn How to Swallowtail Mate: Mate in 1
This middlegame puzzle is a classic mating pattern from the Scotch Game / Scotch Gambit, where White’s active queen and knight coordinate against an exposed black king. The key idea is to recognize how pressure on f7 can become decisive when the king lacks safe squares and the defender is overloaded. Even though material may be messy, king safety dominates the position, and the attack ends immediately once the mating net is complete.
