tarcellius:
In a general sense, you could try to reference the AI of a chess program. The best, easiest one I've seen is Tom's Simple Chess Program that you can find at this website:
http://www.tckerrigan.com/Chess/TSCP

It follows the general need for board game AI:
1.) find legal moves (harder in pente than chess since more legal moves available for the most part) and potentially prune out terrible ones
2.) find a way to assign a score to a position
Hope that helps!

Ever?
