Learn How to Spot Swallowtail Mate: Mate in 1
This puzzle comes from the Russian Game, specifically the Stafford Gambit, where one side’s king safety has collapsed and a forcing tactical finish appears immediately.

In practical classical chess, these motifs often arise when development lags and the king is left exposed in the middlegame.
