will probably continue to beat computers for
some time into the future. Standard chess is
relatively easy to program. Using the basic
pawn=1, knight=3, bishop=3, rook=5, etc.,
system for evaluating the value of pieces, it
isn't that difficult to teach the computer how to
perform a rough evaluation of the strength of
each side after a combination of moves. Of
course, strong chess programs go far beyond
this basic valuation system in their analysis,
but the point remains that evaluating a board
is relatively easy compared to some other
games. So chess lends itself to "brute force"
programming techniques of simply calculating
every possible combination of moves and
evaluating their outcomes with a relatively
simple board evaluation routine.
But how about a game like the Japanese
game of Go? Here things start to get much
more subtle. Unlike chess, where you can
suddenly lose through the capture of a queen
or king, events proceed much more gradually
and subtly in Go. Furthermore, it requires
some degree of expertise and long-range
vision to evaluate a board position. Unlike
chess, there is no simple pawn=1, knight=3,
etc., evaluation method. Indeed, my father,
who learned Go while stationed in Japan
many years ago, can whip the best Go
computer programs I send to him despite the
fact that he considers himself just an
"average" player. He says that the programs
make a lot of silly strategic mistakes.

(4 Comments)but I think it is probably still far from being a
"God-like" machine which is able to play
perfect chess. In a match between this chess
machine and God, I would put my money on
God, even if He plays black and gives the
computer a knight handicap.
