Ekren convention

In the game of bridge, Ekren refers to a preemptive opening of 2 defined as 4-4, 4-5, 5-4 or 5-5 in the majors and 3–10 high card points. This conventional preempt was designed by Bjørn Olav Ekren from Norway and is an example of the modern style of highly aggressive preemptive bidding.
