Yeah, sadly, webworkers are the only way to go really. You can also process the search in chunks, but that basically requires writing an iterative search, which is not as fun.

Awesome job! Great to see another strong JS engine on the scene :).

I played them against each other at 2s a move, and Garbochess (http://forwardcoding.com/projects/ajaxchess/chess.html) barely prevailed, although it was a toss-up in the midgame for quite a while. My guess is that they are quite ...

Added the ability to analyze positions in this release (if you have a browser that supports web workers - chrome, firefox, safari). Also, if you have a browser that supports workers, the engine will output it's thinking line in real time as ...
