Score one for humanity. After four grueling sessions of human vs. computer poker, the human players managed to outlast and outwit the bot. It was by no means an easy task, as the computer performed strongly on day one. But, by the second day, the human players seemed to have a pretty good feel for the way the machine played the game, giving them the leg up. Assuming that computer, dubbed Polaris, represents the vanguard of AI poker, it would seem that it'll still going to be a long time before computers can compete at the top level, as they can do in chess. This particular match offered the computer optimal conditions, as it faced an opponent heads up in limit poker; in a no-limit game with a full table of opponents (conditions that would make it even harder to calculate proper strategy), its performance would have likely been significantly worse.
