Boden's Mate.

Nice Boden's Mate - intersecting the paths of the two Bishops to check the King and block the King's escape to three squares with his own pieces and the edge of the board blocking him in the other directions.

I have been trying to pull off this stunning checkmate ever since I found out about it. The first time I saw it, I was amazed that the queen could be sacrificed to make way for the bishop. I recently made a checkmate OTB that was similar, but it wasn't the same as a pure Boden's.
