Of course not, and that´s good so - otherwise Chest would have a BUG!

>Please (re-)read the discussion about 0-0-0-0 first...

I did read it, but ´0-0-0-0´ is definitely an illegal (better: nonexisting)
move, and so this discussion is not about ´Chess´ but about an exotic
(and also nonexisting) version of chess - call it ´FairyChess´ or whatever.
And so also the above given ´solution´ of this chess problem isn´t
correct at all!
