Re: New Tool for Tuning with Skopt

I'm trying it now, using xboard protocol, and I'm not really successful because python-chess seems to be rejecting "usermove=1". Anyone experience this before ? Yes, this is frustrating.

Re: On-line engine blitz tourney June

Myrddin is connected, but I won't be available to manually join the tournament. Can you do it for me, please?

Thanks!
