Learn How to Spot Swallow's Tail Mate: Mate in 1
This puzzle is a classic mating pattern in a sharp middlegame, where the enemy king is boxed in by its own pieces and pawns. The key idea is that the queen can deliver a direct checkmate because the king has no escape squares, no useful blocks, and no safe capture. Even though the material balance heavily favors Black, tactical king safety matters more than material when the mating net is already complete.
