Please recommend a two-player online chess game

I recently met a friend’s young son, who is a chess player and wants to play online. (They live in Georgia, I live in Minnesota.) What is a good free site where friend’s son and I can play chess against each other online?

Thanks.

Chesscube.com. This site runs in your browser using Flash, so you don’t need to download a separate program.

FICS. The Free Internet Chess Server. This requires that you install an interface program to connect and play.

There are also a number of pay sites, such as PlayChess and ICC.

Thank you!

I used gameknot.com for a while, and it was both free and did about everything I’d want an online chess game to do.
