Chess
From xat wiki
Chess is a xat game which allows you to play chess with another user in private chat.
Note: The chess app has no built in turns or rules, so it is your job to make sure you and your partner are playing properly (or playing by agreed rules).
Starting a game of chess
To start a game of chess, click on 
from the left side applications menu and select 
. Then, private chat a user who also has the chess app open. Any user can take the first move.
What are the rules?
You can read the rules of chess here.
So, how do I win?
The players must enforce the rules between themselves so they must also decide who wins.
