Learn How to Spot Swallowtail Mate: Mate in 1
This puzzle comes from the King's Gambit Accepted, Cunningham Defense, and it is a classic middlegame mating pattern rather than a long strategic squeeze. White’s queen and rook coordinate against the black king, which is stuck in the center with limited defenders. The key idea is a direct mating net: when the king’s escape squares are boxed in and a critical line is open, a single forcing move can end the game immediately. Recognizing these patterns is a major skill in classical chess and tactical puzzle solving.
