It is able to search through the game tree and make a game-theoretic optimal move every time. It only has a search and leaf-node evaluator in it. Now, I put in both of those things so that it can understand tic-tac-toe better, and win more games. This is NOT a knowledge-based program. It is a search-based program. There is a large difference. That heuristics exist in Chess Tiger to aid the search does not change the fundamental nature of the program. I am not suggesting that it is impossible to have a knowledge-based program. PARADISE is a good example of one, though AFAIK it did not play complete games. Dave
