Learn How to Swallowtail Mate: Mate in 1
This middlegame puzzle is a classic mating pattern from the King's Gambit Declined: the enemy king is stuck in the center, and White’s queen and rook coordinate to create a direct mating net. The key idea is that the king’s escape squares are stripped away by its own pieces and pawns, so a single forcing move can end the game immediately. In classical chess, these patterns often appear when development and king safety matter more than material.
