To be able to reason about the rules of a game so trivial that it has been solved for ages, so that it can figure out enough strategy to never not bring the game to a draw (if played against one who is playing to not lose), or a win (if played against someone who is leaving the bot an opening to win), as mentioned in [0] and probably a squillion other places?
