For casual chess players, a neat and easily accessible platform will be more than enough. Usually we just want to enjoy a chess game or two when we have "a cup of coffee". In this case InstantChess will be an ideal choice. I was attracted by its elegant interface when I visited InstantChess for the first time. I got to learn more about this website after several games. Immediately after the first game I found I was able to store my moves in the standard PGN format so that I could review my games whenever I like. This is such a small basic feature, but in fact many online chess services don't give you this option. And soon after a week or so, I decided to change my screensaver, and let my computer enjoy the beauty of chess even when I'm not around.
