Please, allow me to add my "this problem is wrong" email, just so we are 1 closer to the reveal. Unless you mean KxP RxP#. No it clearly says white to move. Arrrrrgh

I don't think there is a mate in two in this position.
Here is the FEN of the position, as posted by you: "7R/7p/5P1k/4BKpP/8/8/8/8 w - g6 0 1"
The definition of FEN, as described in Wikipedia (http://en.wikipedia.org/wiki/Forsyth-Edwards_Notation) says:
"En passant target square in algebraic notation. If there's no en passant target square, this is "–". If a pawn has just made a 2-square move, this is the position "behind" the pawn. This is recorded regardless of whether there is a pawn in position to make an en passant capture."
See if you can solve this one. White to move and mate in two:

Well, I didn't look at the FEN, and maybe he got the FEN wrong. But if you look at the Black pieces, the black pawn must have just moved two squares. All other possible black moves are illegal.
Edit - For example, the black king couldn't have just moved from g7 because that means White's f-pawn must have just advanced, but that's impossible, since the white king is immediately behind the pawn.
The FEN says it's White to play move #1 next. The only possible explanation is that this is the initial starting position, i.e. the players are playing a game from a set position.

Er, OK then...
I can't believe that Geoff! Of all the gall, trying to slip something like that past us! I'll never listen to him again! First he tells us that the Lewis pieces aren't really chess pieces, then he tries this FEN finagling! Hmph!

Arrrrrrrrrrrrrrrgh! OK. But still aaaaaaaaaaaaarrrrrrrrrgh! Thanks for stopping me from eating my own foot off trying to solve it.
You must always follow what's on the board, not what's hidden in a FEN.
You don't look at the captured pieces off the board, how many of you have
been mated by piece off the board?
So why are you now suddenly looking at the hidden FEN?
(If you look under the board you will see it's still a mate in 2)
But to clarify things. If you go The Corner you will see the original diagram
is not a FEN but a series of GIF's pasted together so the charge levied at me
by Fat Lady that I am misleading my fellow RHP members is false and I demand
a Forum Ban (35 minutes will suffice).
Had another email this morning about this problem.
The lad thought the board was the wrong way around, when it's still a mate in 2. (That is just a coincidence).
I can see on the next Corner I am going to have to post the solution.
(all this from a poxy birthday cake - remember I saw the position on
the cake and it reminded me of this problem).
