From the FAQ:
How strong is the program?
Very strong. I know what I mean : I've been vice world-champion in 1996, and the program consistently beats me. In fact, I have been refining Cassio's othello engine for more than 10 years now, using the best artificial intelligence techniques known to me. The program has won several tournaments (both human vs. computer and computer vs. computer tournaments), and is competitive with the top programs running on PC and UNIX platforms.
