As a beginning go player (10 kyu amateur), one of the most interesting
aspects of the game is how much difficulty computers have with this
game. I believe that Go is unique among board games in this aspect.
As you know, the game of Go is played at three board sizes: 19, 13,
and 9. To answer your question, a computer has not yet beaten a
computer at the minimum board level of Go, which is on a 9x9 board.
Althought it is possible that a computer may be able to beat a human
on an even smaller board, this has never been done with a
professional. I don't find this likely, however, as we need to
remember that the game gets easier for the human as well, on smaller
The best and only example of a game in which a computer has played a
top professional go player on the minimum board size is a game with
Saiko Masataka (8 dan professional!) against the programs "Many Faces
of Go" and "GoAhead." This is known as a "multibrained game," because
to help the computer out, a human player chooses the best move between
the two programs.
The computer was given a two stone handicap at this board size, and
was allowed to go first with 0 komi, but despite all of these
advantages, it still lost to Masataka.

After further research, I have found that technically speaking, a
computer can beat a human at 3x3, 5x5, 7x7 Go. (Go board sizes are
always in odd numbers).
The reason for this is that all the possible sizes under size nine are
"solved" by humans. Because Go's komi is designed to enlicit a draw,
perfect play will always result in a draw if the human plays perfect
positions (and this is already known) on any board size less than 9x9.
5x5 and 7x7 have been solved, by people, not computers, so there may
some errors :) I've seen some of the diagrams from the 5x5 solution,
have a copy. It's been published somewhere. The 7x7 solution, I
and never saw it, and as far as I know it is not published. Of course
first move in both cases is at the center.
