I haven't played chess in any regular capacity since high school, but it's always fun to return to the game. There is a neat little site called chesshere.com that allows you to play realtime and non-realtime games. The non-realtime ones are reminiscent of chess by e-mail, but very well designed and great for getting in a few moves during lunchtime.
If you want to play against a "top-seeded" amateur, send me a challenge at jedidjab79. I promise to not lose before the seventh move :)
