3d asking

[jerome keslin]

Hi, 

Forgive the question which has nothing to do with KS, but I was curious to know if anyone has heard of, or plays the following :

After a 3 club preempt, a 3 diamond responds asks opener for a 3 card major. If he has one , he rebids the OTHER major to right side the contract.

I've heard of it.  (I think it's in _Preempts A to Z_.)  

Unless you preempts are always very classic, I'd suggest using the 3D response as something more like Ogust.  It doesn't matter too much what the other responses mean as long as 3C-3D-3S means "my suit will run opposite Ax or Kx".

In a couple of partnerships I play something suggested by Peter Boyd:

• 3♦ shows an invite in a major or doubt about 3N
• 3♥ = I would reject a ♥ invite.
• 3♠ = I would accept a ♥ invite but reject a ♠ invite.
• 3N = I would accept either major suit invite and 3N is fine with me.
• 4♣ = Sorry!

Another version that I have seen is 3♦ as Puppet to 3♥ to either a) play 3♥  b) differentiate strength of immediate/delayed 3♠. 

 

Scientists can then decide meaning of immediate 3♥ and responder’s 3♥ followed by various rebids. I can’t recall which pair(s) were using this, so can’t check for the follow-ups they used.

 

Finally thought of who might be playing that treatment. At one point Brink-Drijver used:

3!D = PUP 3!H  a) !H, to play  b) !S, FG  c) doubt about 3N  d) !H & !S

 

Historical note: confirm 3♣ - 3♦  ask for 3-card major is mentioned in Preempts A to Z [Sabine Zenkel & Ron Andersen]. Fuzzy memory has someone mentioning the convention before that publication.

 

Current note: at least one Dutch pair uses the 3♦ ask and defines the immediate 3♣ – 3M  conditionally a) 1^st seat favorable = NF  b) otherwise F1
