The tournament system is "arena" tournament. Each round there is a game: one player from each team.
Each team is composed by 10 players, ranked in order of increasing strength. The loser is eliminated, while the winner keeps playing in the next round. The tournament is over when one of the teams has no players anymore. The Chinese team consists of strong amateur players (some of them - top amateurs, world champions). Our European team has a few pros, the rest are strong amateurs.
