1929.0. "What is double?" by DAVIDB::DMILLER (This bug fix broke what???????) Mon Feb 10 1997 14:22

	One more weird one from Hudson - and this time neither JK nor BB was
	involved.

	Without giving hands for now, what does this auction mean?

	Pard	RHO	You
	1D	3D	Dbl

	You look at the opponents' card, and it doesn't say what this is.

	If you think 3D is a stopper ask, showing a long running minor, does
	double imply a diamond honor wanting it led, or does it warn against
	a diamond lead, or is it something else entirely?

	If you think 3D is natural (Another common thing I've seen), is
	double negative?

	And if 3D is GF Michaels, is double a desire to double one of the
	suits, or does it suggest a diamond sacrifice?

	And lastly, would you ever double without asking for an explanation?

	More of the story in my next reply...

1929.1Confusion among the ranksDAVIDB::DMILLERThis bug fix broke what???????Mon Feb 10 1997 14:3426
	Looking at QTxx-KQx-J987x-J, it seems obvious to you that this is a
	stopper-ask.  Partner doubled with this hand, without asking what the
	meaning of 3D was.

	Next hand bid 4H.  I now asked the 4H bidding what 3D was.  "I presume
	it's some sort of Michaels bid", was the reply.

	I'm looking at KJxx-AJxx-KTxx-x.  I know she hasn't got a clue what
	the 3D bid really was.  I'd like to double, but I'm afraid the 3D
	bidder will run to 5C, and that might make.  So I quietly passed.

	The 3D bidder passed, and now it's back to partner.  He'd like to
	hit it, but with the explanation he just heard, 4H might make, so
	he bid 5D!

	Full layout:

				QTxx-KQx-J987x-J
		xx-x-Qx-AKQTxxxx		Axx-xxxxx-Ax-xxx
				KJxx-AJxx-KTxx-x

	As you can see, we have a good shot at making 4S, while 5D is down
	one.  The best action is to pass out 4H and set it a bundle.  Should
	we have looked for recourse?

1929.2shows diamondsGAAS::BRAUCHERChampagne SupernovaMon Feb 10 1997 14:3511
  Since you're doubling a partscore at Imps in a possible misunderstanding,
 I think you have to be able to beat 3D !!  So, by logic, it shows diamonds
 enough so that 3D probably isn't natural.  I think you DO NOT set up a
 force by this.  That is, after 1D-3D-Dbl-P-P-3S-P-P-?, opener is invited
 but not forced.  However, you could have the agreement that such doubles
 DO set up a force.  Mostly, you'd ask, or get an alert.  I'm not sure
 that any of the popular treatments require an alert, however.  Cue-bids
 are mostly not alertable, and I'm not all sure what is a "standard" 3D.

1929.3Methods and madnessDAVIDB::DMILLERThis bug fix broke what???????Mon Feb 10 1997 14:3611
	One final question.

	For those you play gambling 3NT bids, what is the difference between
	1m-3N and 1m-3m?

	Should one be no outside controls (Gambling, as if the opening bid
	never happen), while the other has some outside controls and just
	needs a stopper in opener's minor?  Does it make a difference if
	the opening bid is in a major?

1929.4One more treatmentCADSYS::GROSSThe bug stops hereMon Feb 10 1997 17:534
With some partners, I play that the jump cue shows the highest and lowest unbid
suits.
