Pure Mate

A pure mate is a checkmating position in chess in which the mated king and all vacant squares in its field are attacked only once, and squares in the king's field occupied by friendly units are not also attacked by the mating side.

The following is one of my fastest wins, if not THE fastest win using the King's Gambit. It happens to be one of the rare times I used the Bishop's Gambit variation.

It also happens to be a pure mate.
