The best Othello computer programs can easily defeat the best humans. As early as 1980, the program The Moor beat the reigning world champion, and in 1997, Logistello defeated the human champion Takeshi Murakami 6:0.
This dominance is not seen in games like chess, where the best computers are about equal to the best humans (although the Hydra machine may soon change that), or
Go, where even average human players trounce the best computers.
