Swallows Tail Mate Puzzle (Rated 854): Spot a Mate in 1 — Swallowtail Mate

This puzzle is a clean example of a mating net in the opening, where king safety matters more than material. White’s king is stuck in the center, while Black’s pieces are already aimed at the vulnerable king zone. In classical chess, these positions often reward active piece placement and forcing moves over slow development. The key idea is to notice when the opponent’s king has no safe squares and one precise check ends the game immediately.
