This is a classic puzzle. Not the exact position, but the moves. I don't know why I posted this.

That is really old.  Older than Atilla the Hun probably.  But I once used this in a game against a 5th grader.  He was laughing because I hung my Queen and didn't see the smothered mate.  Then the tables turned.

Hilarious. What kind of idiot thinks that a person makes a move that obviously loses a queen for no reason? I bet you laughed and he cried.

If you play chessmaster 9000,you can see this checkmate when you open the program in the starting video,with only 8 pieces on the board.It is the same.

Yes. It's the classic smothered mate.
