See my previous comment that sets forth my answer to this comment. The Fool's Mate "puzzle" would indeed be a puzzle to my granddaughter, who has just learned how the pieces move.
What you seem to imply is that to be a puzzle it has to be difficult for you.
As far as the "forcing" element being required in a puzzle, my answer to that as far as this puzzle is concerned is that the forcing move in this situation also happens to be the move that checkmates. Granted, this is an extremely elementary puzzle, but it would still be a puzzle to some.
And such wouldn't be a puzzle unless there was a forced nature to the moves that ended in the smothered mate.
How about we just post the start position and label it Fools Mate Puzzle?
If you think that makes it a puzzle then you need some more chess experience.
