First Computer Wins in 9x9 Go for Black with Komi 7.5

Abstract

For computers, 9x9 Go is by far easier than 19x19 Go. The usual komi for 9x9 Go is 7.5. However, until a recent date, it was observed that computers could only win games against professional players, when computers played as White. Computers playing as Black was considered much more difficult. This contribution reports the two first wins Black against professional players. So far they are the only two wins. One game is against a top-ranked player, the winner of a recent major tournament.
