The humans vs. computers battle just got a little more complicated, if you're keeping score. The Mainichi Daily News is reporting that for the first time ever, a computer has beaten a human Shogi champion, Ichiyo Shimizu, in Tokyo. The game lasted six hours, and the computer reportedly pursued Shimizu "aggressively" from the start. The governing association of pro Shogi players will now review the game to determine whether it will allow the computer to move onto challenge another player.
