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!
(hide) If you want to play a game with an opponent of a similar level, you can define a required BKR range for a new game invitation. Then nobody with a BKR outside this range will be able to see/accept it. (Katechka) (show all tips)
