Learn How to Swallowtail Mate: Mate in 1
This puzzle is a classic chess endgame mating finish where the attacking queen delivers a forced mate in one. The key idea behind a swallowtail mate is that the enemy king is boxed in by its own pieces and pawns, leaving only a tiny set of escape squares. In positions like this, queen activity and king safety matter more than material, because one precise check ends the game immediately.
