Hi!
There is a new version of the problem child available at
http://ehochpi.de/~steffen/sorgenkind/
Main change: A big bug in Sorgenkind 0.3 (stalemate / mate detection doesn't work correctly in some rare cases - thanks to Werner Schuele for pointing that out!) was fixed.
I've also done some tweaking, so that version is probably a little bit stronger than 0.3.
Best,
Steffen
