The 2008 edition's rules have been published, and commented on.
The Go section of the tournament used a mixed system that used eight separate Swiss Pairing tournaments of up to 24 players to select two players. These sixteen players then competed in a Single Knockout Tournament to determine the final winner and other rankings.
