Openings are usually easy for computers because they can be drawn from databases with probabilities . Closings are the strongest moves a chess computer can make because a computer can figure out inevitable paths to the end . The middle game has neither extensive database calculations nor clear paths to the end , so computers use complex algorithms often the product of machine learning , and thus humans don ' t understand these algos well that calculate multiple moves and the next move . Some chess engines calculate many moves in advance , and that ' s what takes time . Mazes , on the other hand , are completeinformation problems . There is no enemy trying to screw with your plan . Many smart algorithms can solve millionmove mazes in under a second . I guess you could think of it this way one maze is one maze , but a chess move , to a computer , is hundreds of mazes that your opponent gets to choose between .
