Oh, you mean THAT one! Well, obviously it's not an exact replica, as the program prevents that. BTW, sometimes in haste I'll leave out a pawn (or even a rook), which allows the problem to be posted; that's not the case here.
It was nothing like it. My bad. Sorry. Indeed there are many puzzels here. Maybe other puzzelcreators leave out a piece by mistake, then someone puts out the original. I guess that has happened before.
