ajax chess game

Need a JS expert to build an online 2 player chess game using ajax (JS) and PHP, no flash or java. I want something that is light and efficient so that it sends as little data as possible, as few times as possible, back and forth. It should also be smart so that connection problems don’t kill the game, that if a person loses wifi for 4 seconds and comes back, they can continue playing. The code has to be well documented, and built from scratch because I will eventually want other games to be built on the same framework if possible. The game should be designed so it can be used on a regular server, and scale to a large number of concurrent users. There are several open source chess game codes available, ideally you will just add the multiplayer component to it, but you are welcome to build the chess logic from scratch if you want. Open source chess links: [login to view URL] or [login to view URL] It needs to have these features: • User registration • User Login • User Profiles • Friends list (search for and add email/usernames/names to a friends list) • Keep track of wins/losses • Play against computer • Instant action (randomly join game) • Play against a friend • At the end, quite game or play again Please see attached file for all requirements ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
