Flat Chess is a chess application that lets you play with your friends on a nice board in a no-fuss manner.
In striving for programming simplicity, it has a few quirks. Please read the Flat Chess Tips found behind the link on the bottom. It will help you sign up and invite friends. And it will help you with operation. It only takes five minutes to read and you will find everything will work smoothly thereafter.
You can play at the same time or you can play whenever you want. That is usually how it is with me. Where I make a move and close the application and come back later to make another move. But you are welcome to schedule a time with a friend and play without closing the browser. You will be notified in the application as soon as a move is made.
If you feel compelled, please let me know what you think!
