The Western Conference is an association of three ACBL Districts (17, 21 and 22) in the Western United States. They organize Sectional Tournaments at Clubs (STaC), and provide information on upcoming Western States Bridge events.
STaC games are held three times a year. Each tournament lasts for one week and has morning, afternoon, and evening sessions. Dozens of tables from several ACBL districts play the same hands. You can win 20+ silver masterpoints in one session of Bridge.
