Chess Project Protocol

Since spring break, I've busy on VM and study Solaris/Linux/BSD. Now, I need to do my homework on designing Chess Project Protocol, which is a class project for my Client-Server class. I did some sample command but I've not officially written any protocol. My guess is something base on HTTP/1.1 or POP3, which has been taught in class.

The worst thing is ... I don't know how to play chess! hahahhaaaa...
