This is a variation of the Kiss of Death mate but in this one the pieces are arranged in a specific sequence - as if making a sandwich.
In fact the Earl of Sandwich (also known as John Montagu) loved card games. He always carried with him sandwiches made of two pieces of bread with a layer of butter. These were named after him. And although the Earl loved cards he nevertheless left his mark not only in cuisine but also in chess. Specifically in this mate. See for yourself - a real sandwich on the board made of kings and queen.
