A Flash 2-player chess game I found - it's not very good - but I have posted it here so that you can test out my vB Flash Player hack. When I say 2-player, I mean literally, another player sitting next to you.

I think this one is public domain.
Just download chess2.txt and RENAME it to chess2.swf (I cannot attach SWF here for some reason), then upload it into your forum directory.
To play it in your forums, link to this URL (changing it to match your forum directory):

Any more better Flash games, please post here and share.
