9x9 Go is by far easier than 19x19 Go for computers. However, until a recent date, and with the usual 7.5 komi in computer-Go, computers could only win games against professional players as white; playing as black is considered as much more difficult. This paper reports the two first and only wins as black against professional players, including one game against a top-ranked player, winner of a recent major tournament and therefore clearly accepted as a top pro.
