Each court is assigned 4 or 5 players of roughly equal ability. A round robin is played where you partner with each player on your court multiple times. Based on the results you move up or down in the club's rankings for the next round robin. It's basically a promotion/relegation system where the top performer is promoted one court, the bottom performer is relegated one court, and the middle performers stay put. Of course, it's also dependent on which players show up on any given night.
Participants must arrive and sign up by 7:20 p.m. Participants must be at least 14 years old and must be able to stay until 9:30 if necessary. Courts will also be available for regular play.
