Agoraphobia (by Loyd right?) It is illegal because no pieces have been captured yet the pawn structure suggests captures have occured

Yes it's Lloyd (1858) and actually called "The Arena"

All that have to occur is that White under-promotes 6 pawns in the "Bishop Problem"

I prefer this one with Pc5 -> b5, making it dual-free.

Huh? Oh, really a DUAL. I thought you meant two solutions. But then 1... Nf6 and 1... d5 can be exchanged too. What kind of a PG is this 🙄
