In param.txt there was no personality loaded. The program played considerably weaker and I think a couple of times a new ply was reached -I could see that in Uci-debug mode from Shredder- but not communicated as a new iteration. I hope this was only in the version of Pro Deo that gets loaded if it cannot find a personality file. It is possible to check that with param.txt Regards, Eelco
