Opener's Rebid in 1 Club Auctions

After the step response, opener "opens" the bidding.  The choice depends somewhat on the step response.  The "opening bid" can be in notrump or in a suit.  Over a notrump opening, a simple Stayman-Jacoby structure is used, even though the transfer fails because that was the step response.

Usually opener bids suits in the standard order of longest suit first, and responder bids suits at the lowest level before bidding suits at the next level.  Standard order is:

  1. Longest suit first.
  2. Highest ranking of five-card suits.
  3. Four-card suits up-the-line.
With non-touching five-card suits, opener may bid the cheapest five-card suit first.

Rules for the lowest-level first are:

  1. Longest suit at lowest-level first.
  2. Highest ranking of two five-card suits.
  3. Four-card suits including diamonds up-the-line.
  4. And only then suits at the next level. 
Again, with five spades and five diamonds, responder may choose to bid 2 rather than 2 over 2 .

These rules apply over a step response.  After a two-level response, both players bid suits in the standard order.

If responder bid 3 rather than 2 , opener will bid 3NT and the spade game is missed.  Opener would have a more difficult problem over 3 if he lacked the count for game.

Up-the-line includes the minors and finds the diamond slam.  3 is a splinter in support of diamonds, and the responding hand becomes good.

If, after 1 , opener rebids a suit, five or more cards are expected.  The exceptions are:

Recommendation:  With a singleton ace or king, bid notrump over 1 or 1 .

Bid 1 .  If partner is short in spades and has 3-6 HCP, he can choose between 1NT and a six-card suit.  If you bid 2 over 1 partner can only bid a six-card suit (or a strong five-card suit).  You will miss 4-3, 4-4, and probably 5-4 spade fits.

Bid 1NT.  Partner will use Stayman or Jacoby with a major.  If he doesn't, you will play notrump.  Why pinpoint the diamond lead?  If the response had been 1 , then bid 1 .

Is it acceptable to bid 1NT over 1 with a singleton?  If you are willing for partner to use Stayman and Jacoby, the answer is yes.  On both of these hands I would rebid 1NT.  Then, I would accept a transfer to hearts with the singleton heart.  If you rebid 2 rather than 1NT you will miss 5-3 major fits.

It is acceptable to bid notrump with a five-card major or a long minor.

Recommendation:

  K x

  A Q x x x x
  J x

I bid 1NT over 1 , 1 , or 1 .  I bid notrump with any excuse.  The system allows a 2 response.  One advantage of the 1NT rebid is that the opponents are more reluctant to bid over a balanced 16 count than an unbalanced 16 count.

Not to rebid notrump over the step response is stupid.  It is amazing how often the concealed suit is led.

Club-Notrump Auctions

The strength of the notrump rebid depends on the step response.

After the 1 Step

The most usual auction after 1 is:

1 1
1NT

and 1NT shows 16-19 HCP.  The next stronger auction is:

1 1
2NT

Here 1NT shows 20-21 HCP, or compensating values.

  A K Q x x x

Eight tricks is worth 2NT.  Finally the auction

1 1
2 (a)  2 (b) 
2NT (c) 

is forcing to 3NT.  This auction is Kokish, and all the bids to this point are artificial.  2 is artificial and forces 2 unless responder has a reasonable six-card minor.  Opener can have either 24 HCP or 9 tricks at notrump.  Nine tricks is more likely.  I might have:

  A x x
  A
  A x x
  A K Q x x x

The alerts: 
(a) 2 forces 2 and more often is a game force without hearts. 
(b) The fourth alert.  The exception to a 2 bid is a reasonable 6-card minor.  My notion is K-Q-x-x-x-x. 
(c)  Opener forces game.  Stayman and Jacoby apply.  If opener's rebid is anything but 2NT, his bid shows hearts and whatever he bids.  Thus over 2 :

Kokish applies in competition whenever partner shows 0-6 points, and the bid before 2 was 1 or less.

After the 1 Step

1 1
1NT

The 1NT bid shows 16-17 HCP, and is nonforcing.  Responder may use Stayman or Jacoby and then pass the response.  The jump to 2NT in the auction

1 1
2NT

shows 18-up HCP or compensating playing tricks.  For example:

  K x
  x x x
  A Q x
  A K J x x

is 18 notrump points.

After the 1 Step

The 1 step creates a game force.  The strength for 1NT and 2NT are the same as over a 1 response.

1 1
1NT

1NT=16-19 points.

1 1
2NT

2NT=20-up HCP.  I think 2NT over 1 denies a five-card suit.

A balanced 22-23 hand is opened 2NT.  Responding creates a game force.  With 24 points, open 1 and use Kokish.

Note that these auctions do not include the 1NT or 2NT responses to 1 , or other competitive auctions where responders first bid is in notrump.  Those auctions proceed naturally.  Opener may not get to play the hand, but he does not decrease his chances of playing the hand by using Stayman or Jacoby.

Stayman and Jacoby

After the notrump rebid, relatively normal Stayman-Jacoby auctions follow.  These rules also apply in competitive auctions if all competition was before the notrump bid.  Against a vicious preempt opener might have to rebid 3NT.  The system is on.  Later I talk about interference after the notrump bid.

The rules apply to both natural and artificial defenses.  If the defense is artificial, the chances are that one opponent is flying blind.  The rules work when the overcall is a psyche.

Stayman:  Bid hearts first.  In a game-forcing auction, Stayman promises a four-card major.  In a game-forcing auction, opener may jump to three in a five-card major.

Scrambling Stayman:  Scrambling Stayman occurs after 1 — 1 — 1NT and after a 12-15 notrump opening.  Responder's rebid in a non-game auction is an attempt to find the best part score.  Scrambling Stayman does not promise a four-card major.  Opener passes when a seven-card fit is found, or when responder rebids a minor (or possibly 2NT in a 1 auction).  Obviously, instead of "Scrambling Stayman", I could say "Nonforcing Stayman", except that expression has been corrupted.  In "Scrambling Stayman" nothing is forcing once a seven-card fit is found.

Stayman in the 1 — 1 — 1NT auction is forcing on opener to 2NT.  Responder can quit when he wants.

Forcing Stayman:  Forcing-to-Game Stayman is used after the 1 step, after 1 — 1 — 2NT, or after a 2NT opening.

Jacoby transfers.  Diamond and heart bids are transfers.  In a game-forcing auction or after a 2NT opening, accepting the transfer shows three-card or four-card support.  Refusing a heart transfer with a notrump call denies four spades.  Opener may jump in response to a transfer.

A spade bid is Minor-Suit Stayman.

A jump in a minor shows that minor.  I always use Jacoby and do not jump in the majors.  If I did, the jump would be natural.

The are some differences that follow from information provided by the step response:

The "bid beautifully" rule is off when opener rebids notrump.  Once responder knows the final contract, he may jump to it.

1 1 PassPass
? 

Rebid 1NT.  This is the track at other tables.  The only difference is that you know LHO has a spade threat.  If partner has a yarborough, it could be wrong to bid.  Partner's point count, however is more apt to be 5 or 6 rather than 0 to 4.  The chances are good that the plus is your's.  A possible difference is that at other tables LHO led a spade and here he may lead an off-suit.

If, in the above hand, you had four hearts instead of four diamonds, both 1NT and double are allowed.  I would double.

  Q x x
  A K x

1 Pass1 1

This is a different track.  RHO has asked for a spade lead.  1NT is acceptable.  Pass is best.  Partner, with some count will reopen with a suit bid, a notrump bid, or a takeout double.  If you pass or double, partner can bid two-of-a-minor to play.  If you bid 1NT, he has to go to the three-level to play a minor.

Scrambling Stayman is used in auctions where responder indicates 0 to 6 points, opener rebids 1NT, and your RHO passes, doubles or bids 2 .

PartnerRHOYouLHO

Scrambling Stayman also applies after a 12-15 notrump, and a pass or a 2 bid by RHO.

Nonforcing-to-2NT Stayman is used in the auction where opener shows 7-8 points and RHO passes over 1NT:

PartnerRHOYouLHO
1 Call1 , DBLCall
1NTPass? 

If RHO bids over 1NT, then pass functions as double and other bids are natural.  They cannot play below 2NT undoubled.

Forcing-to-Game Stayman applies when you are known to have 25 points, after Kokish, or when the opening is 2NT.

Scrambling Stayman arises most frequently in auctions that begin with 1NT (12-15), and with 1 -1 - 1NT.  In the following examples we omit the 1 -1 start.  Examples of finding a seven-card major fit using Scrambling Stayman are:

1NT2
2 2
?

Opener passes with three spades.

1NT2
2 2
?

Pass with three hearts, and bid 2 with three spades.

1NT2
2 2
?

Pass with three spades.

An example of a "stop" auction is:

1NT2
2 3 or 3

Responder's second bid is an alert.  An extreme application of "Scrambling Stayman" would be to use this auction independent of your major holding anytime you want to play 3 or 3 .  We do not do this.  If you choose to do so, I feel that the minor suit bid should be a "special alert" to the effect that it is your partnership style.  (In Stayman as originally written, 3 and 3 were "stop" bids, and responder's 2 bid did not show a major.  In most current versions of Nonforcing Stayman 3 is forcing.) 

When should you use Stayman and Jacoby?  There is no problem in truly forcing auctions.  These conventions are used almost whenever you have a four- or five-card major.

Let us examine the decision to use Stayman and Jacoby in the nonforcing 1 -1 — 1NT auction.  If opener is required to be balanced for a 1NT bid, then it is reasonable to Stayman with 4-3 in the majors and a balanced hand.  This is the case over a 1NT opening where opener is usually 4-3-3-3 or 4-4-3-2.  After a 1 opening, 1NT may be done with a long minor, or possibly a singleton.  My rules are:

  x x x
  x x x x x
  x x x

Always transfer, and opener always accepts the transfer even with a singleton.

  x x x x

1 1
1NT? 

Stayman can be used with any point count.  We are a hero when partner has a four-card major and a 4-3 major fit may be better than 1NT.  The awkward case is when partner is 2-2 in the majors and bids 2NT over our rebid of 2 .

  Q x x x
  K x x x
  x x
  x x x
 
1 1
1NT? 

It is wrong to use yarboroughs as example hands when you are more likely to hold 5 or 6 HCP rather than 0 to 4 HCP.  One of the options of my hand dealing and bidding program, BID95 is "stats".  The program generates tables for Walsh vs Walsh and Big Club vs Big Club for various opening bids in first to fourth seat.  For example in Big Club, you open 1 in first seat about 10% of the time and almost 42% of the time in fourth seat.  Pass and high-level preempts become unlikely in fourth seat.

Passing 1NT with this hand will tend to yield an average result.  Bidding 2 is an attempt for a better result, and the result will be different from that of the field if opener has 16-17.  It partner has 18-19, the field is on a different street, and our action simply is an attempt for the best result.

This example shows that you may play three-of-a-minor after a 7-8 point response.  Whether or not you ever want to bid this way is questionable.  In a team game, 3 is a reasonable scientific bid.  Opener may pass or bid 3NT.  Pass, 2NT, and 3NT are alternatives to 3 .

Continuations of 3 or more clubs, 2 , and 3NT are all reasonable.  It is difficult to create a hand that insisting on a minor will always be correct.  (A jump to 4 is not a splinter in support of hearts because 3 is nonforcing.) 

Game-Forcing Stayman and Jacoby auctions are relatively standard.  The one additional feature is the trump support rule in Jacoby auctions.  This rule allows responder to confidently go past 3NT with either a suit bid or a splinter bid.

Versus Interference

After a 0-6 auction:

1 Call0-6Call
? 

If opener rebids 1NT, the observations are:

1 Call0-6Call
BidCallPassCall
Dbl

Hopefully your understand my notation.  Opener and the opponents have been bidding away and responder has done nothing.  (I assume that pass as his second bid was not a business pass of a takeout double.)  Opener's third bid is a takeout double.  The "double is takeout" principle could be extended to later rounds of bidding.

1 Pass, Bid0-6Pass, Bid
PassPass, BidBidPass, Bid
PassPass, BidDbl

I have reversed the roles of opener and responder.  The last double is takeout.

I can build long auctions from either side of the table where all doubles are takeout:

1 Pass1 1
Dbl2 PassPass
Dbl3 PassPass
DblPass
 
1 Pass1 1
PassPassDbl2
PassPassDbl3
PassPassDbl

Though I have not seen any auctions like these in twenty-five years, all the doubles are takeout doubles.  The doubler could have interspersed a suit bid or a notrump bid between the doubles, and the doubles would still be takeout.  Both LHO and RHO could be bidding - even arguing about trumps - and doubles are takeout until the bird across the street chirps.

The opponents can bid several suits.  Think takeout doubles.  In any of these auctions the bid of a suit previously bid by them is natural and nonforcing.

Some Examples

  Q x x x x
  K x x x x

1 Pass1 Pass
1NT2 PassPass
2 Pass2 Pass
Pass3 PassPass

Here you scrambled to a 4-3 spade fit and then allowed the opponents to play 3 undoubled.  This may not be right, but it is systemically okay.

  x x
  K J x x
  x x x
  Q J x x
 
1 Pass1 Pass
1 2 ? 

Pass is approximately this hand.  Again the pass is forcing.  You should have 0 to 2 spades, 2 to 4 hearts, 2 to 4 diamonds (no diamond tricks with four diamonds), and 3 to 5 clubs.  With any other distribution you would bid or double.

Interference After the Notrump Rebid

This is a proposal for a new set of agreements when the interference occurs after the notrump rebid.  Human nature being what it is, interference usually occurs on the first round of bidding.  Interference on the second round happens when second seat doesn't know what a direct 2 over 1 means, or when fourth seats action arouses second seat's interest.  Second seat is allowed to delay his interference to the second round and we must be prepared.

The Law of Total Tricks suggests that we should play at the two-level when there are 15 trumps, and the last side out should take the push to the three-level when there are 16 trumps.  (The average number of trumps on all deals is 16.7.) 

Thus, if we have to decide between double as business and double as takeout, we should choose takeout.  I studied a set of 48 deals where our 12-15 notrump was overcalled.  I found 13 deals where I wanted to play negative doubles and 2 deals where I wanted to play business doubles.  This is consistent with the "law." 

Our agreement on overcalls of our weak notrump is negative doubles, and for consistency it is negative doubles through 3 .  If they overcall 2 we play system on.  Here "double = Stayman" and negative doubles mean the same thing.  This is our agreement even if the overcall is artificial.  2 for the majors cannot buy the majors - one of the bidder's majors may be four-small - or he may have forgotten his system.  If the bid is artificial they may have to pull the negative double.  If responder passes opener is not expected to reopen.

How do these arguments apply to the big club auctions?  I think they apply exactly when responder has shown 0-6 points and the rebid is 1NT.

1 Pass1 Pass
1NTCall

Rebid After 1 — 1 — 1NT, and then Interference
Overcall Rules
2 Double = Stayman and system on.
2 — > 3 Negative doubles.  Suit bids natural.  2NT = "Do the right thing."  Cue of a natural bid is Stayman.
Double System on.  Redouble — > 2 and responder passes or corrects to diamonds.  This is different than over a 1NT opening.
A reopening double is takeout.

What about other big club cases?  If responder has 7-12 points, then we have a force to 2NT or 3NT, and a pass corresponds to a negative double.

1 Pass1 , 1 Pass
1NT, 2NTCall

After Delayed Interference in 1 — 1 , 1 Auctions
Overcall Rules
2 Double = business.  Pass = Stayman.  Rest of system on.
2 — > Double = business.  Pass = negative.  Other bids natural.

A reopening double is business.

I expect the group to discuss and do computer studies on the above.

Your bid depends on the overcall.  Over 2 you transfer to spades and then bid hearts.  Over 2 bid spades and then hearts.

Proceed normally when the overcall occurs during the scramble and before you have shown the majors.  Pass denies a four-card major.  Double is a penalty double.
