HOW THE FORMAT WORKS
All players play three round-robin matches against rivals in their group to determine a winner and runner-up from each group, who advance to the knockout stage of the tournament. In the semi-finals the winner of Group A plays the runner-up of Group B and the winner of Group B plays the runner-up of Group A. Semi-final winners advance to the final.
