I'll be white then, but I can't guarentee I'll post often...
Actually, I should be going and play some real-life chess now.

Add me to the team black

http://www.chess.net
get the java version.
if they still have it.:-*

I'll join black to balance Evert.

Yeah, this is very good addition. So if you are starting some risky attack make sure your teammates can understand your plan.

Yes Kirr, turn to the dark side.

X-G: but there is the risk that someone might play with the script and give it input while we play, thus changing the board. I could change notation to something like show?board=X&move=MOVE, so that the move changed only board X, but i think it would be more confusing.

On the other hand i could just link with show?board=X (where X would remain a constant for all of our game)but this way there would be no way to see the old moves.

Would do you people say?

I agree on the risks and problems you pointed out.
The script is good and sufficient as it is.:)
You could add some quickstart manual under the scripts interface page,
showing the standard ASCII board with a legend (r=black rook, n=black knight, Q=white queen, etc...).

Starting the game... (more players can still join!)

Because it's been years since I played chess regularly.

At any rate, I've made a chess widget of my own! It's at http://monkeyblah.com/chess.php and takes information in algebraic notation, each step separated by a comma. It should support most constructs (including disambuating captures and castling), but note that marking checks with + doesn't work.

The current game with my script looks like this:

http://monkeyblah.com/chess.php?e4
(http://monkeyblah.com/chess.php?e4)

A future move might be, for instance, img http://monkeyblah.com/chess.php?e4,e5 or something similar.

A longer example just to get a feel for it:

http://monkeyblah.com/chess.php?e4,e5,Nf3,f6,Nxe5,fxe5,Qh5
(http://monkeyblah.com/chess.php?e4,e5,Nf3,f6,Nxe5,fxe5,Qh5)

Most servers have the maximum GET set to about 2k. So the issue will probably be at the browser.
IE locks it at 256 I think. None of us should be using IE anyway, so that won't be a problem.
Firefox can take something much longer I believe.

Or ML's script might lock it down, shrugs.

If it becomes a problem I suggest adding a bit of MySQL database to the mix. Add a script for adding a "game", which accepts the series of moves, assigns an unique id, adds it to the database, and then returns the id. Then modify the original script to accept an id as opposed to a serious of moves (or both).
Or use one of those url shrinkers. trimurl or whatever it was.

Yes, do so
