Tried a standard piece placement, but castling not possible, tournament. It didn't work:

BUT, I think I figured it out now! Want to try? Unrated.
(I'm sorry if it doesn't do what it is supposed to, but it is just an experiment)



Hello everybody!
Go ahaed and tyr to castle, if you want to.
This is a test to see whether or not it will work in this position,
So, there is no penalty, like being kicked out of the tournament, if you do.
But, don't be surprised if you can't castle, because you are not supposed to be able to.
Good luck!
