Fritz, Junior 5, etc., they all are already playing at grandmaster level. They
all have earned ratings above 2600 USCF. As soon as multiprocessor support is
available for Junior 5, things will become even more difficult for humans to win
in Chess. - In Chess, the "brute force" approach seems to succeed.

Only Whei-Chi (also called Go) is beyond this "brute force approach", at least
so far. Shogi, although more complex than Chess, could also be a good candidate
for high speed search engines, as others have already pointed out.

Starting from a well designed Chess program, add a super-computer to it and you
will probably not lose many games. It appears that "human-based" grandmasters
make more "modest" errors than expected. Just analyze their games using Junior
5, Crafty, etc.
