Defence against Multi 2's


There are a number of  different strategies to defend against Multi 2's. The system I use is simple and not far removed from standard bidding.

Over a two level bid.

Bid a suit with an opening hand and a five card suit.

Bid 2NT with a hand that you would have 1NT. You need stoppers in the suits that openers promise.

Double with shortage in opp suit. You may have to delay the double until you know what suit the opposition has.

Lets look at some examples:

After 2D

2D could be a weak 6 card major or a strong hand. S has to bid.

1.

2D
4
AJ4
KQJ852
1092

South West North East


2D 3D

Show your opening hand and 5 D's

2.

2D
AK3
AJ4
KJ82
1092

South West North East


2D 2NT

You would have opened 1NT id the opp hadn't bid 2D You can stop both majors.
N is unlikely to have either of the strong hands.

3.
South West North East


2D Pass
2H
Pass Pass Double
2D
AK32
A5
K985
1092

You are not sure if N has S/H/strong hand. If you double and N has spades you could be in trouble.
Wait! you will get another bid as S will probably bid 2H and North will describe hand. If he has H's then your double will show 4 spades.

4.
2D
AKJ32
A
KQ85
1092

Here you are much stronger and need to show partner you points. You intend to bid your suit to show 16+.
In the unlikely but possible event that N's suit is spades then bid NT or double again and hope partner sees it as penalties.

Over 2H

2H shows 5 H's and 5 cards in another suit. S may not bid
South West North East


2D Double
2H
3D Pass 3S

5.

2H
AK32
A
K1085
1092

South West North East


2H Double
2S
Pass 4S
Pass

Double to show 4 spades, can't afford to wait as S and partner may pass. You can cover the minors if partner doesn't like spades. Here partner has bid to game and therefore must have 12 total points.
