Greetings,

I have spent some time looking for any good online multiplayer chess systems that use Javascript (no Flash!). I have not been able to find anything - does anybody know of one?

To that end, I started developing my own and am looking for feedback, requested features, etc. It is at http://www.chessdatabaseonline.com.

Chess Database Online

Current features:

- 1.2 million game database, currently only searchable by player name and board position. Board position searches are very fast and return back the first 200 games that match the position as well as statistics on all moves played from that position.

- Javascript play/analysis engine with a playing strength of roughly 2200-2400.

- Play against other players, easy registration via Facebook

- Powerful chat system

- Realtime piece movements - ie, you can watch your opponent actually moving the pieces around the board.

- Create any number of variation branches for any move for study purposes

- Uses Javascript web sockets to enable multiplayer play without using Flash.


Not currently supported:

- Touch input
- Opening classifications
- Observing games

Chess Database Online

Constructive criticism is always welcome 

Cheers,
