    If you are not the author of this problem, you should credit the original author... If you are, well, probably you could credit yourself ("I composed this mate-in-two:..") ! – Evargalo Jan 22 '18 at 16:53

Use the fact that the rook is pinned, and that the king has few squares left; I'm thinking that 1.Rd8 Kd3 (only possible move) 2.Nc5# should be the solution.

[White "NN"]
[Black "NN"]

1.Rd8 Kd3 2.Nc5#

    +1 for a nice try. 1...Kd3 breaks the pin, so 2. Nc5+ Rxc5 – user1108 Jan 21 '18 at 20:57

    @Bad_Bishop Note that 2...Rxc5 is impossible due to the d8 rook pinning the d5 rook again. – Scounged Jan 21 '18 at 21:17
  • Cheers @Scrounged. I thought you wrote 1.Re8 the first time I read your answer :-) – user1108 Jan 21 '18 at 21:21
  • @Bad_Bishop Like any good mating puzzle, it doesn't start with a check :-) – Arthur Jan 22 '18 at 13:33

Black is not in check, but still only has one move:

Check mate.

Move the rook onto the same row as the king, king moves to the only possible square, checkmate by moving the bishop to a6?

  1. Rh4, Kd3 2. Ba6#

    2. Ba6+ isn't a checkmate, Black can reply with 2...Rb5+. – JiK Jan 22 '18 at 14:20
