This bidding system was devised and developed by Mr. Bård Olav Ekren, who is from Norway. The original version has been altered to reflect the evolving stages and has been complemented with several concepts and principles. The bidding system has been catagorized independently.

Ekren 2
Opening - Ekrens 2 Hearts Opening - The 2 Hearts opening shows at least 4-4 in the Majors and 5/6-10 high card points. In Norway this conventional method is called Ekrens, named after Mr. Bård Olav Ekren, who originated the convention (although he used the 2 Spades opening to show this distribution).

Ekren MaxFirst Principle - Starting a relay against a hand that is very variable in strength (at least 3 high card points difference from minimum to maximum), the first answer to the relay is often according to the MaxFirst principle. This means that the 1st step in the answer is reserved for all the hands with extra values, whereas all the remaining steps shows minimum values and some particular distribution.

Ekren RKCB or Ekrens Roman Key Card Blackwood - The Ekrens bidding system uses Roman Key Card Blackwood, RKCB, as its first and main tool for slam-going purposes.

Ekren VoSS'N Principle - This principle called VoSS’N is an acronym for Void / Single / Single / None. It is mainly used when the responder has shown at least 8 cards in two specific suits and we have a known fit (one of the two suits is partner’s suit). It is also used when we open a Minor on the 1-level and partner preempts.
