UNUSUAL 2NT OVERCALL Surendra Mehta August 2007

Surendra Mehta August 2007 20073 Unusual 2NT Overcall After an opponent opening bid of one of a suit, a direct jump to 2NT is unusual. Hitherto this has meant a very strong hand (20 – 22 points) with a stopper in opponents suit. Some Bridge players make a jump 2NT overcall to mean something else.

Surendra Mehta August 2007 20074 Unusual 2 NT Overcall It shows 5:5 distribution in the two lowest unbid suits, and a fairly weak hand (normally 7-15 points) Over 1 or 1 , 2NT shows at least 5:5 in clubs and diamonds Over 1 , 2NT shows at least 5:5 in clubs and hearts Over 1 , 2NT shows at least 5:5 in diamonds and hearts Simpler version: Over 1 of a minor, 2NT shows 5 cards in both the major suits and over 1 of a major, 2NT shows 5 cards in both minor suits

Surendra Mehta August 2007 20075 Additional Unusual Auctions The Unusual 2NT can also be used after both opponents have bid, as in these situations: 1H Pass 1S 2NT 1H Pass 2H 2NT 1S Pass 1NT 2NT If opponents bid 2 different suits, then 2NT indicates 5 cards in both the remaining suits The Unusual 2NT convention is useful because it gives up the strong 20-21 point natural 2NT overcall, which practically never occurs, in exchange for pre-empting the opponents and paving the way for a possible good sacrifice.

Surendra Mehta August 2007 20076 Unusual No Trump Overcall Unusual 2NT is like a pre-emptive bid but you can show 2 suits in one bid!! If vulnerable, your suit quality should be fairly solid with 2 honours in each suit Alert! The 2 NT overcall should be alerted, as it is not a natural bid. Responses to 2NT are NOT alertable.

Perhaps your bid will stop the opponents finding their major suit game.

Surendra Mehta August 2007 200710 Disadvantages of Unusual 2NT Overacall You or your partner might forget this is unusual Your partner may make a mistake in deciding which are your two long suits – Play simpler version. Must agree with your partner which version you are playing. Occasionally playing unusual NT will lead you a contract where you will go down heavily You can no longer use 2NT overcall to show 20-22 points. Generally, in duplicate game, the advantages outweigh disadvantages. Normal 2NT overcall showing 20-22 points is very rare. If you have such a hand, double first, and then bid NT – showing 19+ points.

Surendra Mehta August 2007 200711 Defence against Unusual 2NT Overacall The old-fashioned approach to dealing with these overcalls was to use cuebids of the opponent's suits to show stoppers or controls. For example, after 1H by partner, and 2NT by RHO (clubs and diamonds), your 3D cue-bid would show a diamond stopper and ask partner to bid 3NT with a club stopper.
