Ekren convention

In the game of bridge, Ekren refers to a Norway. It can be seen as an example of the modern style of ultra aggressive preemptive bidding.

Responses to a 2 Ekren opening:[1]

Pass = To play (can be a tactical manoeuvre in the absence of a major suit fit and does not guarantee long diamonds)
2/ = To play
2NT = Relay (invitational or stronger)
3 = Natural, not forcing
3 = Invitational with 3-3 in the majors
3/ = Preemptive, to play
4/ = To play

In responding to the 2NT relay the opener indicates whether (s)he holds a minimum or a maximum (because of their playing strength 5-5's are generally considered maximum), and - in case of a maximum - the distribution in the majors:

3 = any minimum (responder's 3/ rebid now indicates an invite)
3 = 5-5 min or max (creates game force)
3 = 4-5 max (creates game force)
3 = 5-4 max (creates game force)
3NT = 4-4 max (creates game force)

Ekren convention Modifications

Variants of Ekren include the use of the 2 opening to indicate a weak hand with at least a 4-4 in the majors.[2] This treatment has the advantage that the left hand opponent of the opener can hardly gamble on the fact that (s)he will get a second chance to bid.

Another variant that is popular in the Netherlands (where it is referred to as Tilburg Two) and Belgium is to accommodate the Ekren hands as a weak variant in the strong 2 opening. This leaves untouched the 2// openings which are commonly utilised in the Low countries as Multi 2 diamonds and Muiderberg (also known as Tartan or 'Jón og Símon') openings. Also, a 2 relay is now available to responder that can be used to ask for the longest (or better) of the two major suits.
