The Wernher Open Pairs national bridge championship is held at the summer American Contract Bridge League (ACBL) North American Bridge Championship (NABC).
Typically starting on the Tuesday of the NABC, the Wernher Open Pairs is a four session matchpoint pairs event, with two qualifying sessions and two final sessions. The event is open to any player, but due to its current conflicting schedule with the more prestigious Spingold Knockout Teams, it is generally considered to be the weakest open national event on the calendar.
