Many consider chess to be the best game ever invented. Chess imposes a set of rules and has finite limits, but just as you start to think you’re finally solving its mysteries, chess thwarts you. Sometimes, therefore, the game is frustrating, but far more often, chess proves both surprising and delightful. The deeper you get into chess, the more of its secrets you unearth — but the game has never been tapped out. Even today’s monster computers are far from playing the theorized “perfect” chess game.
