Learn How to Swallowtail Mate: Mate in 1
This chess endgame puzzle is a classic mate in 1 based on a mating net around the enemy king. The key idea is that the attacking queen can deliver a direct checkmate because the king’s escape squares are already covered by its own pieces and pawns. In practical classical chess, these patterns often appear when one side has active pieces, a centralized king, and the opponent’s king is boxed in by limited mobility.
