I must be missing something because this looks astoundingly easy. Clearly, the black king can't move. All it takes then is a check on the H file or the 1st rank for mate. So my first move is:

1. N6b4, with the treat of Rh6++

Black has only one response to prevent mate, and that's Rh8. White then follows up with either Rf5 or Rf7 and black can't stop the back rank mate and has no way to check the white king.

I let Fritz8 take a go at it, and the best it comes up with is #4. If Fritz can't do it, then I know I can't. I give up.

1. Be5 Rd2
2. Ba2 Re2
and white can't mate with the next move.

I'm beginning to think that marinakatomb is either pulling our leg, or that there is something a little off with the puzzle.

Beat you to it!

I'm done, I don't think there is a 3 move forced mate here. There must be a mistake with the puzzle, because I don't believe marinakatomb would knowingly post an unsolveable puzzle.
