Learn How to Spot a Swallowtail Mate: Mate in 1
This puzzle is a classic middlegame mating pattern from the King’s Gambit Accepted, where White’s queen and rook coordinate to exploit the exposed black king. The key idea is not material gain but king safety: when the enemy king is stuck in the center and its flight squares are restricted, a forcing check can end the game immediately. In classical chess, these patterns often appear after rapid development and open lines toward the king.
