Subject: Constructive bidding after your pre-empt

In mid February, there was a thread in rec.games.bridge re
constructive bidding after a preempt.  However, I deleted the articles
before commenting.  Thanks to Markus Buchhorn's, fine work with the
*Bridge Newsgroups Archive*, I was able to find them again.  There was
no universal agreement and usually not an integrated plan.  Here is a
method my partners and I play.  

You open with a 3 level pre-empt in 1st or 2nd seat, partner bids a
new suit at the 3 level.  (Forcing, else what does partner do with 5-5
majors and about 23+ HCP?)  Partner's hand is unlimited; what
information can you always give him about your hand?  Opponents
passing.

1)  Do you have support for his suit?  After your pre-empt and admit
to support, he cannot count on better than 3 small.

2)  Do you have a good suit?  Lets define a good suit as one that will
run if partner has a doubleton honor.  That limits it to 7 to the AK,
AQ, or KQ.  The J would be a +.

After 3 diamonds, pass, 3 spades, pass:

A)  You have 3 card support and a good suit.  You would seldom
(probably never) have a good 7 card suit, 3 card support for a major,
and an Ace to cue-bid, and may not have any outside honor.  However,
you will always have a short suit.

You hold:   S xxx     H xx   D   AQJxxxx   C x:
Bid your short suit, 4 clubs.  If partner has as little as 6 spades to
the AKQ, the heart A, and Kx of diamonds - 6 spades is a fine contract
in spite of only 23 HCP in the two hands!

B)  You have 3 card support but a ragged suit (or no singleton if you
preempted on a 6 card suit), just bid 4 spades.  Partner will need a
real fit if he needs to run your suit.

C)  You do not have 3 card support or a good suit, bid 4 diamonds.

D)  No fit but a good suit.  Bid 3 NT which says "I have less than 3
card support for your suit; my suit will run if you have a doubleton
honor; I may have absolutely no help in any other suit,  . . . . .
but,  . . .  this is our last chance to play in 3 NT if we belong
there.   Please pull it unless you have a fit and all suits stopped."
You have the example hand, but partner bid hearts.

Hope it comes up sometime (but not against me)!
