Fair points. But in the end though, people may as well just go somewhere else to play chess then. Why bother with the X10 connection at all.
The only way I thought this might work was if someone who knew what they were doing with the coding, & had the inclination, could set things up here.
Not being an expert, I don't know how tricky this might be. Certainly the just-2-player-per-thread option would be a doddle. But that's not very ambitious!
In a slight off-topic point, I was just wondering ; how would
Deep Blue of 1997 fare against a chess program running on the average home PC of today? Any ideas?
