This Help page lists the ACBL web site and several other ACBL links of interest.
ACBL Web Site: Our District 21, Unit 500 and our Bridge Clubs are members of the American Contract Bridge League (ACBL). It is a wonderful resource for duplicate bridge players in the U.S.A. This is the single web site address for the ACBL with information about Districts, Units, Clubs, Tournaments and how to play the game.
ACBL Club Results: ACBL provides an "ACBL Club Results" system that allows game results to be uploaded to the internet. Any club that belongs to the ACBL and uses this system can be located on the ACBL Web Site, and results displayed. A very nice feature of this is the ability to merge hand records with game results. Our Unit 500 began using ACBL Club Results, as of Nov. 11, 2013. So, if you look up Clubs in California, Castro Valley, Hayward and San Leandro, you will see our results listed.
Nationals: AKA NABCs or North American Bridge Championships are held three times a year. San Francisco has hosted an NABC most recently in Fall, 2012 and Fall, 2007
Tournaments: There are Sectional and Regional Tournaments played all over the country. This area of the ACBL web site lets you search for past tournament results or future scheduled tournaments.
