Disarray - Now, Rife At the Black Court (Posted on 2007-10-25)

While still at home the Black King, in rather similar circumstances as his White oppressor, finds disarray at Court [K, Q, QB, QKt, QR] on his Queen’s side.

Again, he is the only occupant of the first rank and all 5 pieces are spread within the domain [K1 – QR5] with none being a direct threat to another.

Find a situation where the occupants again enjoy a lesser domain, and the Queen again can force ‘mate’ without herself being under any threat; after a successful "coup d'etat" who cares if another is also under threat?

Bonus:
I offer 28 scenarios where the Court enjoys 'serenity', but how many fit the "more reduced" domain category?.

RE: Bonus.
I nominate 3 instances, two have no QR occupancy (one of which is my solution) and the other has no 5th rank. Q to Kt1
I do need to refer to my prior poser Disarray - Anarchy At the White Court
There I indicated my strategy for finding my multiple case scenarios; but there I also noted my lapse in not being purely methodical.
Again I commend the findings of Dej Mar and Charlie.
With regards to Charlie's program I doubted there would be little adjustment needed, as reflected in the next paragraph.
The fact that both problems had 48 cases where pieces could be placed without threat was a bit of a surprise, but .... the chessboard is, by and large, symmetrical.
