I saw this problem in a Jennifer Shadade lecture (around 31:40).
White to play and mate in 1 (White started at the bottom of the board as usual.)
This is not the 1st time I've seen this puzzle. The ONLY answer is e3-a3#.

I disagree.
I think it's black to move.

Nice proof, but that's not the position you originally posted.

It sucks being proved wrong, doesn't it?
In case it is not perfectly clear, I refuse to stipulate the side to move in the FEN. The composer did not stipulate it. The solver is supposed to figure that out for themselves.
Welcome to the world of retros.
You did stipulate the side to move, it's part of the FEN. You just purposely chose to be misleading rather than accurate. Perhaps a screenshot of the position would be better another time.

No, I've never had a problem admitting a mistake. Other people get married to their mistakes, to the extent that they will make up all kinds of bizarre excuses to cover themselves. Problem is, usually the only people they ever fool are themselves.
OK, prove it. Admit your mistakes in this thread.
If it helps, I know a divorce lawyer who works cheap.
So, what's the mate in one move if it's black to play?

It's a mate in one for White.
So 1...Rxc6 2. Qb8#; 1...other 2. Qb7#.
Mate in 1´s all very well, but I prefer this sort of problem: what´s the shortest route to mate here?
White to move: Qa4#
