Learn How to Swallowtail Mate: Mate in 1
This puzzle is a classic mating net in a middlegame position, where the enemy king is boxed in by its own pieces and pawns. The key idea is to recognize when a queen can deliver a direct checkmate because escape squares are covered and capture or block options fail. In classical chess, these patterns often appear after a trigger move creates a final weakness around the king. The tactical theme here is a clean mate in 1, not a long combination.
