Unusual 2 No Trump - A conventional defence method

  1. The unusual 2 NT is a conventional defence method. It is designed to show a two suited hand with one bid.
  2. The logic and reasoning behind the convention is to deprive opponents of bidding space and also to describe your distribution.
 It has a pre-emptive effect putting pressure on the opponents to find their fits and games at the 3 level.

The Unusual 2 NT is used after the opposition have opened the bidding.
It is artificial showing 2 unbid suits and should be at least 5 cards in each suit.
There is no point count minimum, although vulnerability should be a consideration.
The convention is a direct jump to 2 NT after an opening bid.
eg. After a IC or ID opening, 2NT shows both majors.
After a IH or IS opening, 2 NT shows both minors.

 

PARTNER'S RESPONSES.

Partner usually bids the suit he has most tolerance for.
With equal length in both suits, bid the cheapest suit. If I had an honour in one of the suits, I would be inclined to bid that suit.
EG If partner bid 2NT showing the majors and you had S 95 and H 72, just bid the hearts. If you had SJ4 and H 97. I would bid the Spades.
If partner bid 2 NT showing the minors, the same method applies.
NB. The unusual 2NT is NOT on after the opponents open a weak two.
Over a weak 2, 2NT shows a good balanced hand and a stopper in their suit.
The unusual 2 NT is NEVER on after an artificial opening such as 2Clubs.
