What is your description of the theme?
Theme = Schnoebelen. A promoted piece is captured, having never moved.
That's very helpful.
Since a promoted rook at h8 is captured having never moved, why is my position not an example of Schnoebelen?

I was about to say that playing dumb doesn't suit you. But then I thought, maybe it does.

Perhaps it does, or perhaps I'm not just playing. But I honestly wonder why, if the theme is Schnoebelen as you stated, the shorter game doesn't qualify.
My latest thought is that the actual theme could be a Schnoebelen for both sides. I believe you're right in thinking that #6742 is the shortest problem of that theme.
To extend the theme somewhat, I wonder if someone, without using computers, can find another problem of the same length which also exhibits a Schnoebelen for both sides.

Bingo. Theme acquired.
I checked the chess problem database server and found some others of the same length, but none shorter, at least without fairy conditions.
In case anyone is interested, here's another problem of the same length in which both sides show the Schnoebelen theme. But I was not able to find it without using my computer.
@6758
With the Schnoebelen hint it is not hard:
I hope this position works the way I want it to.

Seems we both confirmed the duals.

Since there are so many more SPGs, is "duals" the right word? I guess we could say the "multiples".

There's no need to put too fine a point on it. One dual is too many for SPG's.

I do like this concept of an (almost) excelsior SPG where a pawn captures all the way to the back rank. I don't suppose our experts know of any?

That will be a good one if someone can find it. Here's a position with a unique SPG including an Excelsior white and a pawn that needs a non-capture move before capturing all the way to the back rank.
I tried to make this position more fun to solve (than another version I made), but that may make this cooked. Mostly confident that it is unique, though.
hmm
does the theme necessitate capture?
if so i dont think your position is part of the theme
Bingo. It doesn't count.
Since #6742 refers to "this theme" without telling what it is, it's up to the solver to infer the theme. I did solve it, and decided the theme is a position with a unique SPG in which a promoted pawn is captured by the opposing king. My view is that my position meets the theme and has a shorter solution.
