Learn How to Swallowtail Mate: Mate in 1
This puzzle is a pure tactical finish in a sharp king-safety position. White’s heavy piece activity and the exposed black king create a classic mating net, where the final blow is delivered by a queen sacrifice-style pattern on the back rank and around the king’s escape squares. Even though material is not fully equal, the attack is all that matters because the king has no safe flight squares and the checking piece cannot be captured or blocked.
