Learn How to Spot Mate in 2: Swallowtail Mate
This chess endgame puzzle shows a classic mating net where the queen and bishop coordinate to trap the enemy king on a narrow set of squares. The key idea is not material gain but king restriction: once the king is forced onto a vulnerable square, every escape route is covered. In classical chess, these patterns often appear when heavy pieces and a fianchetto bishop work together to create a decisive checkmate with bishop and knight-style geometry, even without a knight involved.
