Actionscript 2.0 Chess Tutorial?

Hello I am making a flash game for my school project and I want to include elements of chess in the game. Essentially its going to be an educational simulation of the Roman invasion of Britain and I wish the battle sequences to be played out in a chess style format. I've been unable to find any decent chess tutorials and I was wondering if any of you have any advice regarding this. What do I need to learn to implement a chess style game? I know how to make a tile system and I want to be able to have images on those tiles that can move when the player or the computer wills it. I was wondering if you folks have any ideas for tutorials that could greatly assist me in this issue. Other board games tutorials would be useful. Or just any hints and tips that you could give me would also be great. I intend to update this thread with my progress anyway.
