I've finally found a good site to play chess online. You play whenever you can (however you have 3 days to make a move), or you can play as you would a regular time-framed game. Your call.

Check it out (no pun intended) and if you're into it look for me: dzp111 is my user name. I'm sorta good but often loose. grrr..
Non-members can play up to 6 games at a time.
