This is a free chess server
Yahoo chess require a Java download to be able to play. It is free and easy to play. On the previous incarnation of Yahoo chess, I experienced quite a bit of obscene language, so please use with caution!
I have not used Yahoo Chess recently, so any feedback that I can add to this page will be much appreciated.
Please contact me at email@example.com if there are any mistakes or new servers you would like me to add to this list.
