Multi Two’s

by Rowan Ferguson

Why use Multi 2's

With the enormous emphasis in recent times on competitive bidding, the advantage of using multi twos can be readily seen. Not only is it the pre-emptive nature of these bids, which creates an advantage; it is also the fact that many different hands can now he described. Let us examine the bids in turn.

The 2D Opening

This bid carries 3 possible meanings: 

1. A weak two in hearts or spades.

2. A balanced 21‑22 count or

3. A 4441 shaped hand with 19+pts.

Responder has several options available to ascertain which hand opener holds:

2H: Please describe your hand 

2S If your weak two is in spades please pass, but if you have a weak two in hearts, I have a good raise to 3H (ie we have a 9 card fit)

2NT: I have a reasonable hand (16+). Please tell me if your hand is of the strong variety or if you have a good weak‑ two or a questionable weak two.

3H: I have a competitive raise in either major but not enough for game.

Lets look at some examples

The 2NT asks you describe your hand more and you need 16+ pts to do this. You are looking for game if N is top of his range.

Any bid by North at the 3 (inc 3H) level shows a singleton in that suit and 19+ pts. Here south knows that N has 4 hearts so bids to game.

2H's, 2S's and 2NT

All these bids show 2 suited hands.

2H shows 5 hearts and 5 of another with 6‑9 points.

2S shows 5 spades and 5 of a minor suit with 6‑10 points.

2NT shows 5‑5 in both minors.

Let's see how this works:

2H by N shows 5-5 in hearts and another. S enquires about the other suit by bidding the next suit up. N would have passed had his second suit been S.
