Learn How to Spot Swallowtail Mate: Mate in 1
This puzzle is a classic mate in 1 based on a swallowtail mate pattern, where the enemy king is boxed in by its own pieces and has no flight squares. Even though White has a huge material edge, the real lesson is tactical: when the king is exposed and key escape squares are blocked, a single forcing move can end the game immediately. In middlegame positions like this, always scan for direct checks before considering material gains.
