I tried it a few times when it first came out and now I think I'm hooked. I've played for cash a few times and won a dollar twice, but it’s the points that really have me going back. There's something about getting a point reward for winning and losing points when I make a big blunder and waste a game. I was skeptical at first, but I'm really spending a lot more time there now. They do need more players though, it seems there's a small community that digs it, but I would like to add more friends to my profile for those 5-minute dollar games.
Also, I got whooped by a grandmaster the other day, so that was nice. I tried to get him to play me in that outlaw variation that they have. It lets you buy back lost pieces and what not, but he said no.
