The author, Dieter Buerssner, loves C programming, mathematics, chess programming and bicycles! I think he must be my long lost brother.
You will definitely like his program. Since one requirement of the B.O.T.C. contest was public distribution of binary and book, here it is:
ftp://38.168.214.175/pub/Yace/
No real documentation yet, but you're used to that with winboard programs.

This is a port that I have done, and it is possible that I have introduced errors. If an error does turn up, don't bother Dieter. Send me an email instead.
