Question about "shuffle" and "nocastle"

[Volker Pittlik]

And the -variant nocastle does not work because the engine says it does not know how to play nocastle? (Although in reality it does...)...

Possibly yes! It seems this "nocastle" transforms to a relict from the past. Almost all the "wild" positions are just legal positions on the board. Every engine with implemented "setboard" should be able to handle it correctly.

Forget that script. It does the correct thing for a wrong reason. I'll post a corrected version later.

Should work now also on windows with cygwin
