Mr. Harry Shershow
Personal Computing
1050 Commomwealth Avenue
Boston, Mass. 02215

Dear Mr Shershow:

\JJon Ryder wrote a GO program under my supervision, while he was a graduate
student here at Stanford.  The program played a very mediocre game,
although nobody was able to do any better, at least for some time.  I do
not know anything about the Reitman program, however, and Reitman may
easily have surpassed Ryder.

Ryder, himself, was a very good GO player, (a 3-Dan player when he was
here, and he may be better by now) and he was always rather unhappy with
the performance of his program.  Like all really good GO players, Ryder
played somewhat intuitively and he found that transcribing his intuitive
knowledge into a computer program was far from easy.

Ryder left here to go to the Bell Telephone Labs. and I believe he is
still there.  I suggest that you write him, although he seems to have lost
interest in programming GO and may not even have a copy of his old
program that he could send you. Ryder may still be a good source of information
about other GO programs because of his interest in GO.\.
