You'll find them at "fulltiltpoker" poker site. IMO its a pretty average place to play and the pros are rarely ever on. I only once saw Andy Bloch playing at a 5-10 limit table and he made a few hundred before leaving. If you aren't a "real money" player u cant use the chat facility, so u cant chat to the players if they are playing. Still nothing stopping you from watching quietly. Oh, and i think they just use their full names e.g. Andy Bloch
