The idea of a dummy pawn promotion in a r# has certainly been done already, but I do not know of any predecessors, and it most certainly never been done at this scale before.
A.Buchanan: I think this is very original and good: do you think of publishing in magazines at all? One nit: it seems that their are multiple mates after the D promotions. D can go to the squares for R or B mates. So can't really say that the refutations are distinct, in my humble opinion, so for me this isn't quite a double allumwandlung. What am I missing?

James Malcom: Many thanks. I have thought publishing in a magazine, yes; I have made problems that have never been shown. But I have always been unsure of how and where. The refutations are not meant to be unique-they are merely meant to be there. (2020-04-26)
