A very series Bosma
A correct, I hope, rendition of an idea from a couple of years back.
ser-s=11
 (= 2+9 )

Does this work?
EDIT: 9-3-2023 new version, the previous one was dualistic.
 (= 6+6 )
ser-h=18
Bosma
1. d1=S 2. Sb2 3. Sc4 4. f1=Q 5. Qf3 8. e1=B 9. Bf2 10. Ba7 11. Kb8 12. Qa8 15. f1=R 16. Rb1 17. Rb7 18. Sb6 Kb6=

Thanks.
Solution to yours?

Solution added. As you could've guessed, it's my favourite theme: AUW.

Suggestion: For more OTB relevance :-))), a study. Say, Black has an
overwhelming material advantage but the lil bastich of a white king keeps
hiding in triple checks.
Or even a win, think Kb7 - Ka8 Lc8 Sd8 or such.

Why would you want OTB relevance for a fairy condition?

@James Malcom(1)
Series autostalemate seems more suitable for the task, like for example
 (= 2+8 )
Ser-!=10

That may be so, Georgy
Hauke, the only Bosma study atm is the first example there was: pdb.dieschwalbe.de/P1377131

Found a dual in my AUW, posted a (hopefully) fixed version.

@Joost, regarding James' factoid: QED. Bosma wasn't a fairy condition
for a short time, at least by letter of law.
