2 ♦ alerted as 6+ major weak or 19+ and balanced. Looking for answers as to how the bidding for North SOuth should have been. I was south and pretty lost because my partner and I had never discussed defence over a multi 2 diamond. I thought 3♥ might be confusing to partner and 3 clubs would show a different hand.

This hand is from a tournament where most SOuths just jumped to slam when their partner bid spades after the x of 2♥

 

many thanks :)

From an earlier thread you may find this useful:

All 17+ hands (except 17-18 balanced) should start with a double. Waiting is dangerous for two reasons:

 

1. It will be very difficult to describe that powerful hand later.

2. LHO may pass 2♦ and you never get a second chance!

 

(2♦) dbl (2♥) pass

pass 3♠

 

That will be forcing. 2♠ after an initial double would also be strong (17-20) but non-forcing.

I happen to like to play multi-versus-multi. Over 2♦ with south's hand I double, I play this shows

• An opening hand with one of the majors
  
• A balanced hand with both majors stopped and 19-22 hcp
  
• 19+hcp and a three suiter
  

Other bids show,

2♥ good 15 to 18 balanced, both majors stopped

2♠ or 2NT --> transfer to minor with opening hand in clubs and diamonds

3♣ and 3♦ = preemptive, let them figure out from here what to do...

3♥, 3♠ - michaels, bid suit and minor

3NT - monster balanced, say good 22

 

Here I would treat this hand too good for 3♠ and double, planning on clubs later, but 3♠ would get you to slam as partner with double fit will bid game with the meger values. At the table, the bidding would have been

 

2♦-X-2♥-X <--- second double is responsive showing spades.

Ps->>>> >>>>>>>>>>>>> now 6♠ is easy, if overcallers suit was hearts he pass 2♥X.

Well agreeing multi vs multi is a waste of time IMHO unless you think you will have to defend multi very often with this partner.

 

I think Roland's suggestion is very natural. Double-then-bid shows a good hand, we are used to that! Double-then-jump shows an even better hand, we are used to that too.

 

I would hope my auction to go:

(2♦) X (2♥) P

(P) 3♠, then:

3♠-4♠

5♣ (slam try) 6♣

Pass.

I have to agree this is true, with one caveat... If you play multi 2♦ yourself, adding multi-versus-multi is painless and easy. If you face lots of multi's it is also worth considering even if you don't play multi 2♦.
