what happens when a basic member is playing in a tournament and has registered for another tournament. And the second tournaments starts. As the basic member is allowed to play in only one tournament. Is he kicked out of one of the tournament? Is so which one? First one or second?

You don't get kicked out.

Are you sure you can even sign up for the 2nd?

I dont know how I could... but yes I'm. Now I couldn't register to any more tournaments..

Or does chess 960 tourney does not count as tournament? ;-)

I tell you, I am a diamond member.  About 30 cents a day.  It is worth every penny.  The stuff you get is worth the cost of half a Coke a day!

No, I do not work for Chess.com -- just a happy camper.
