Technical stuff

The AI is a simple brute-force AI with no pruning. It evaluates a given position by counting the value of the pieces for each side (pawn -> 1, knight/bishop -> 3, rook -> 5, queen -> 9). It will evaluate the tree of moves, and take the path that results in the greatest gain. To learn more, check out my post on how it works.
