hi bryant,
how about trying it without the tablebases access? I am interested
in that though. its more about understanding the position. and I have'nt found
any program that actually found it draw without tablebases....
thanks.
pavel
ps, pls forgive my ignorance but as far as i know screamer is a macintosh
program , do you have any plan to port it for windows by any chance?
