Beats me! Neither of White's Rooks can even check, which leaves the Queen. Qa7+,Qc7+ or Qd6+ are all losing. This leaves bxa8+ which will lead to mate in 2, or bxc8+ with eventual mate.
What am I missing? Don't see checkmate in 1?
Mate In One!
Sort:
I suppose someone captures a rook and promotes to a rook of the same color!? (4 solutions)

King would take promoted piece, either Rook or Queen. So, not in 1 (that I can see).
actually Rc1 Rxc1 is mate in 1

Why would White move Rc1? That makes no sense. If you want the puzzle solved, perhaps it is mate after a blunder - not mate in 1. Moving Rc1 is just beyond any rational thought.
And, while I don't do puzzles "professionally," isn't mate in 1 the very next move? This would still be mate in two, the mate coming on the second move (even though part of the same sequence of moves).
it is mate in 3 not mate in 1
1.bxa8=Q Kxa8 2.Ra1+ Qa3 3.Rxa3#
Or maybe it is helpmate
1.Rf3 Ra1#
Just kidding
It is helpmate in 2
It is helpmate in 2
Needs a wormhole and Zen to solve it in one!

Ahahahhaha!
Btw, @Arisktotle solved it.
Nah! He didn't, did he? Not in 1. If anything, then in 3.
I'll leave it to RewanDemontay to solve Rocky64's version!
Btw, everyone comes with similar diagrams claiming that it was legal to promote to pieces of opposite color at some time in human history. I doubt that such was true but it is not required to refer to history. There is an active fairy variant named Andernach chess where a unit changes color after it makes a capture. All mates in 1 in RewanDemontay's diagram then become perfectly legal underpromotions, followed by color change. Rocky64's problem "Andernach style" does have a different solution than in the preceding post!
Took me 15 seconds to solve Rocky 64's problem!
While it's not Andernach, try to solve this puzzle I got published online awhile ago!
Selfmate in just 3 moves!

@Arisktotle and @RewanDemontay I'm not sure if either of you have actually solved my problem, since it's a bit tricky!

Pretty easy actually. Black has no last move if White has a mate in one via promotion to a Black rook, so it must be Black to move and mate in one.
Then again, White could have promoted to a Black pawn and Black moved one of them, making it White ‘s turn to move with mate. So it goes either which way really.
Checkmate in one move!
