I see the tournament is set up for round robin matches Wed-Fri. Each player plays each other in the group of four (three matches). The winner from each group of 4 (out of 64 total players/16 groups of four) advances to the weekend for a final 16. Then it is single elimination format. My question is, what if two players from a group of four finish 2-1. How do they decide who advances to the final 16 from that group? I assume it's the head to head winner?
