White usually arrives at this position after a series of sacrifices on the a-file or h-file. It is a type of Anderssen's mate and closely resembles the Opera mate.

A draw is possible in a few exceptional positions if the weaker side has an immediate perpetual check, e.g. with a white king on a1 and white queens on a2 and b1, the black king on e8, and the black queen giving check on d4. Black has an unlimited supply of checks on d4, a4, and d1, and the white king cannot escape the corner.
