Ekrens 2Diamond by Bjorn Olav Ekren

This convention was made by Bjorn Olav Ekren, Norway, and has become very popular here in Norway. The Ekrens 2Diamond opening promises at least 4-4 in the major suits and 3-10 HCP. Ekrens is basically a preempt convention, but it should be used with care if you don't meet with these restrictions:

You should have your HCPs concentrated mostly in the major suits, you should have maximum 5-5, and with 4-4 you should not have an invitational hand against 1NT opening. (These restrictions are my personal opinion based on experience.)
