I'd have to whole-heartedly agree with those folks who suggest that you just not play that person again (whom you suspect of cheating). You could always throw Russ a heads-up, but just move on.
We've a good community here, lots of great folks. Dont let a suspicious game get you down about the whole site.
Heck, I stink (move way too fast, think way too little) and I have a great time!
playing against a computer lacks the discussion that a human can give.
does it lack interest on the board as well?
if the human makes nice conversation, then is it as interesting to play a computer consulter as it is to play a genuine human master?
on a different tangent: there are also bound to be many players who are not that strong when they start here - but they are on there way to being serious competition to our best. They will improve in great leaps as they achieve insights into the game. Lets not blackban them because of their talent. Play them all i say.
