There are 8902 perft(8) in one perft(11) makeing manual updates not to mention setting the fen and sending the answer by mail quite a work. What the distribute perft client does is to recieve fen's from the server, calculate the nodes and send back the answer, and then get next problem. If you don't trust me writing a good program or doing nasty stuff I can garantee you that I've meant to do no such thing. If you don't want to use .Net or don't use windows at all you can't help me. And I can't help you because it would be to much work to make software for all platforms, I used .Net because it was the easiest for me to program. /Regards Albert
