Playchess.com is an interesting international site. Many Grandmasters, (you can watch, on a board not in person, Nigel Short, Yasser Seirawan and Magnus Carlssen playing their games for instance. Even Kasparov drops by once in a while) many International Masters, many FIDE Masters, a beginnerssection (!) (try beating those speedies to start with), chess lessons, chess-training, simuls, live reports from all the major chess events, eight pawn chess, shuffle chess, possibility of saving the games that you played and lots of other features.
People who use chess computers/software outside the special computer rooms for computer assisted chess get their rating deleted.
