Hi Joachim
Pro Deo most probably looses informtion when
hash tables are cleared after each move I think.
And as far as I can remember, Ed Schröder prefers
the option [Clear Hash Table = Never]. In my tests
http://www.utzingerk.com/pro_deo.htm I used the
option "always" ... but to replay 280 games at
60m+10s is a time consuming matter.
