Queen mate where the king's own pawns plug the escape squares
A queen delivers mate to a king with the two adjacent escape squares blocked by the king's own pieces. The arrangement looks like a dovetail joint: queen below the king, two friendly pieces hugging the king at the diagonals. Also called Cozio's Mate, after the 18th-century chess composer who catalogued it.
Queen attacks the king diagonally; king's own pieces block the two adjacent flight squares.
