Learn How to Spot Swallowtail Mate: Mate in 2
This chess endgame puzzle is a classic mating net built around a trapped king and a powerful queen. The key idea is that the attacking side uses a forcing check to drag the king into a worse square, where the follow-up creates an unavoidable mate in 2. Patterns like swallowtail mate reward you for noticing how the king’s escape squares are already controlled and how one active piece can dominate the board.
