Does anybody know a nice chess puzzle, where the question states:
Exactly one piece is drawn incorrectly on this diagram; another piece must be drawn on its position. Find the incorrectly drawn piece.
One needs to make retrograde analysis of the given position and find which of all the pieces is drawn incorrectly.
I really would like to find such a puzzle.
P.S. I would rather like to find an old puzzle like this than to see you creating a new one, because:
I understand that it is easy to create a simple puzzle like this. But this would be too simple.
When you try to create it, it is easy to miss some combination. Meanwhile old puzzles are checked "by time".
But if you really would like to try to create a nice puzzle like this - you are welcome.
