Negative doubles

After a suit overcall of partner's one-level suit opening, an immediate double (through 4D) is for takeout with 7+ HCP at 1-2 level and 9+ at 3-4 level.

  • If there is exactly 1unbid major, double promises at least 4-card in that suit.
  • If there are 2 unbid majors, double promises at least 4-card in one of the majors.
  • If both majors have been bid, double promises at least 4-card in each minor suit.

REBIDS BY OPENER

  • Any minimum bid: Natural, non-forcing.
  • Any jum bid: 16-18 HCP, invitational.
  • Cue-bid: 19+ HCP, forcing.
  • Pass: Converts the negative double into penalty.

REBIDS BY NEGATIVE DOUBLER

  • 1NT or new suit: Natural, maximum 10 HCP, non-forcing.
  • 2NT, single raise, or jump preference: 11-12 HCP, invitational.
  • Cue-bid: 13+ HCP, forcing.
  • Any game bid: Natural and sign-off.

 

Jordan 2NT

If partner opens a major (say S), and overcaller doubles, you bid:

  • 2S with a minimum hand
  • 3S preemptively
  • Jordan 2NT as a limit raise or better.
  • XX in this position shows 10+ points, and tends to deny opener's suit.

You can also use it after minor openings too.

 

 

Cue is limit raise or better

To improve competitive bidding you should strongly consider using this convention. If partner opens the bidding and right hand opponent overcalls a cue bid shows support and at least a limit raise. All raises then become competitive bids.

  1H - (2C) - 3C ; shows heart support and a limit raise or better.

The cue bid is used in this instance to show a specific hand that has four trump support and is at least a limit raise. Partner with a minimum will return to the original suit, and the cue-bidder will only go on with less than an 8 loser hand.

You can also use it after minoropening. Then a cue show the same as inverted minor.

1C - (1S) - 2S ; shows club support and a limit raise or better.

 

 

Cue Raises

In competitive sequences, responder cuebids an opponent's bid to show a limit raise or better in opener's major. Also used on defense. A jump raise in competition is therefore preemptive.

example

1H - (2C) - 3C = show heart support and at least invitational.
                 3H = Pre-empt.

I prefer to use it after our side overcalls. Cuebids of opponent's suit now show a good raise or GF.

example

(1H) - 1S - (Pass/1NT/2C/2D) - 2H = Good raise in spade OR GF.

 

 

Roman Jumps

This is a defense against a weak two preempt in a major. A jump shows a game-going hand with 5-5 in the suit and the other major.

Examples:
Opponent You
2H            4C shows clubs and spades
2S            4D shows diamonds and hearts

Other partnerships may play a Roman Jump shows 5-5 in the suit bid and the suit above it. (Thus 4C over 2H would show clubs and diamonds).


(My idea:) You could incorporate Roman Jumps and a direct cue bid to show all 5-5 hands: 

Over weak 2(major): jump = suit + other major
cue = both minors

Over weak 2(minor): jump = suit + other minor
cue = both majors

 

 

Invisible Cuebids, Splinters, and Doubles

This is an extension of "Unusual vs Unusual." These can be used as a defense against any known two-suited overcall (say Michael's). 

The invisible cue bids work as follows:

Bidding the lower known suit: 10+ hcp, support for partner
Bidding the higher known suit: 10+ hcp, showing the "4th" suit 

The invisible splinters are:

Jumping in the other suits: 10+ hcp, splinter w/ support 
*Bidding the 4th suit: 10+ hcp, splinter w/ support
[note: some may not want to play this as a splinter] 

An extension of this is: 
Direct raise of partner: up to bad 9 hcp, support
Game raise of partner: 8-9 hcp, good shape 
Directly doubling: 10+ hcp, good defense of their suits
pass then double: you could only double one of their suits
pass then raise: up to bad 9 hcp, support, you might have doubled the other suit

 

 

Roth 4C response to preempt:

Over a 3 level preempt, 4C is used as a slam try. Opener rebids:

4D bad hand, bad suit
4H 2 of the top 3 
4S good hand, bad suit
4NT solid suit

 

 

Western Cue-Bid

A cue-bid in the opponent's suit in a competitive auction where no major fit is evident, is a request for partner to bid NT if he can 'stop' their suit..

Example
1S - (2H) - 3H ; ask for stopper in heart. opener bid 3NT with a stopper

 

 

Etter  1 NT

Escape from Doubled 1NT

A mechanism is necessary to escape from a doubled notrump contract.

Especially when playing weak notrump openers.

The simple system played here consists of:

  • Redouble                      =a single suited hand. The notrump opener is forced to bid 2 clubs. The responder then corrects to the suit, passing if it is clubs.
  • 2 of a suit                     =This shows a two suited hand. The suit bid and a higher suit. Therefore suits are bid up the line until an acceptable fit has been found. For instance, 2 hearts shows hearts and spades, opener should pick one. 2 clubs shows clubs and a higher ranking suit. You should leave the lower ranking suit only if it is clear that a higher ranking suit will be better.
  • Pass is to play.

 

Lebensohl vs 1NT

2NT response (when 1NT is overcalled): Artificial transfer bid, forcing opener to bid 3C. After 3C relay, responder may pass (with clubs), or bid three of his suit as a signoff.
3 of a new suit (after a two-level suit overcall): Natrual and forcing.
Double 2-level overcall: Penalty with 7HCP defensive strength.
Double 3-level overcall: Takeout.
Cuebid: Stayman. It promises at least 1 four-card major and denies a stopper in the enemy suit.
3NT: Denies a stopper in the enemy suit. opener pass with stopper in enemy's suit, or explores for a better contract.
2NT then Cuebid: Stayman. It promises at least 1 four-card major and promise a stopper in the enemy suit.
2NT then 3NT: Promise a stopper in the enemy suit.
