Hi friends,

I have recently spend a lot of time improving my evaluationfunction. I have
added a lot of features and studied a number of sources (Crafy, Gerbil, TSCP,
Phalanx, Beowulf etc.). Still my engine is not able to beat TCSP 181 in all
games. Now i want to fine tune the evaluation features. Can anybody give me some
advice how to ga ahead with this process? Is there a EPD set available of good
testing positions for this purpose?

Thnak in advance.
