People play there to win BTC?
well that's the idea... but it's still technically in beta. I'm trying to get it off the ground, so you won't really find any opponents yet. and bitcoinadvertising.com is proving to be a disappointment. i'm still working at it though, i think it's a good idea
What's to stop someone from using a chess bot to choose all of their moves for them, giving them a huge advantage over human players? There are some pretty powerful chess engines that are commercially available, and capable of beating the best players in the world. Not to poke holes in what I think is a pretty awesome idea for a site, but I'm sure I'm not the only one who'll think of this possibility.
