The "Spring", "Summer", and "Fall" NABCs are usually scheduled in March, July, and November for about eleven days.
They comprise both championship and side contests of different kinds (e.g. matchpoint pairs and knockout teams, one-day and two-day) in many classes of competition (e.g. open/women/senior or defined by masterpoints).
The event was contested annually in New York as a separate championship until 1958, when it was incorporated into Spring NABCs.
Awarded to the Open Board-a-Match Teams winners at the fall North American Bridge Championship (NABC), it was donated by the Greater New York Bridge Association in 1965 in memory of Curt H. Reisinger, a great benefactor and official of the ACBL, and replaced the Chicago Trophy.
During each event, the ACBL publishes a Daily Bulletin highlighting attendance, results, schedules, people profiles and interesting hands.
