Thanks to Julia for taking the time to show this Upside-Down Chess position as I believe the variant inventor (George Jelliss) had thoughtfully envisioned it (note that the color of squares in the diagram are inverted).

I also gave this link in the definition section above the problem. Maybe some shorter version of the definition could be added there too.

Oops, right you are! This is AUW+1 for both white and black (not super-auw).
