Bidding after a negative 1D Response to 1C


1.1.1.  Negative Response to 1C, 1D (0-7 HCP)


NEGATIVE: 1: 0-7 HCP (covers most hand but for constructive pre-empts, a good 6 card major is shown with 2©/2♠. ,with 7-8 card suits which are bid 3 for Clubs, 3♠ for Diamonds, 4♣ for Hearts and 4 for Spades) 1 is artificial and 100% forcing. From a passed hand shows 0-6 HCP.
 

First let us consider the likely type of hands opener will have to rebid 1©/1♠ (which is a 1 round force) over 1♣:

·         15-21 HCP a 4 card suit and including (4441) hands and limited hands with a longer minor, (4M432) possible having a suit unstopped or with 2 good 4 card majors

·         16-21 HCP a 5+ card suit including 5M332

·         22+ HCP balanced or 4441 with 4 card major suit, possibly with 2 good 4 card majors or a suit unstopped

·         22+ HCP GF with 4+ major and 5+ longer minor. Hand is unlimited strength..

i) 1: F1 15+ HCP, Hearts 15-21 a 4+ carder, possibly a longer minor, possible 4441 without a singleton Heart.  Also could be 16-21 HCP balanced with 5 Hearts. Could have 16+ HCP with 2 good 4 card majors or one 4 card major and a suit unstopped. Possibly a forcing hand with 4+ hearts and a longer minor, which is unlimited

1♠: 0-7 HCP (0-6 PH) and 4+ Spades, denies 4+ Hearts but note will do with 3 Hearts instead of raising

               1N: 16-19 HCP balanced (17-19 PH)

               Other bids are similar to as over 1N below. Spade bids are only invitational.

1N: 0-5 HCP (0-4 PH denies 3 Hearts with a singleton) double negative lacking 4 card Heart support. If has 3 Hearts will be 3-5 HCP without singleton or any 0-2 HCP. Opener may pass this bid, it is non-forcing.

2: 3-7 HCP (0-6 PH) exactly 3 Hearts, denies 4+ Spades, with only 3-5 HCP (0-4 PH) will have a singleton or void, NF

               2♠: Asks for a singleton; 2N= Spades singleton; 3 denies a singleton, so has 6-8 HCP

2♠: 6-7 HCP (5-6 PH), 3 Hearts (denies 4 Spades), singleton/void in unnamed suit or 5-7 HCP (4-6 PH), 4+ Hearts, singleton/void in Spades. 2N: ask shortness with 3=1♠3, 3♠=1♠4, 3N=0♠4

2N: raise 6-7 HCP (4-6 PH), 4+ Hearts, no singleton or void

iii) 1 NT: 17-19 HCP (in 3rd/4th seat 18-19) balanced, maybe 5 card suit, 5m422 or 6m322. 1N Systems On, 3-level bids have been modified to suit higher range. 
iv) 2♣: 5+ carder Clubs, 16-21 HCP
               Pass: 0 – 5 HCP
               2: 6-7 HCP and a reasonable 5+ card suit
               2/2♠: Natural 6-7 HCP and a reasonable 5 card suit
               2N: 6-8 HCP, scattered values, balanced and no fit
               single raise 5-7 HCP  non forcing
               3: 5-7 HCP splinter and fit
               jump to 3/3♠: 5-7 HCP splinter and fit
v) 2: 5+ carder Diamonds, 15-21 HCP
               Pass: 0 – 5 HCP
               2/2♠/3§: Natural 6-8 HCP and a reasonable 5+ card suit
               2N: 5-7 HCP, scattered values, balanced and no fit
               single raise 3: 5-7 HCP non forcing
               jump to 3/3♠/4§: 5-7 HCP splinter and fit
vi) Jump to 2: Strong 2 in Hearts 22+ HCP or equivalent strength. May have a second suit.
               2♠: Double-negative, 0-3 pts no support
               2N: positive response in Spades                                                           
vii) Jump to 2♠: Strong 2 in Spades 22+ HCP or equivalent strength. May have a second suit.
               2N: Double-negative, 0-3 pts no support
viii) 2 NT: 22-23 HCP balanced, may have 5 card suit but not (5422). 2N systems on.
ix) 3♣/3: 3 1/2 - 4 1/2 losers
       minimum NT: minimum and no support
       raise: minimum and support
       new suit: values in the suit forcing
x) double jump to 3/3♠: solid suit, asking for Aces or void in side suit
new suit: ace in the suit or void with trump. 
               Next step up (not 3N or 4 of solid suit) asks for a singleton or void 
                               a repeat of suit is void not an Ace
                               cheapest NT is singleton Ace
3N: no ace, but a King or a singleton with trump
               4♣: openers is relaying for king or singleton
Raise: no 1st or 2nd round control
               New suit: asks for Queen or doubleton in bid suit
               Step 1: no control, Step 2: doubleton, Step 3: guarded Queen
xi) 3N: 24-26 HCP, balanced may have a 5-card minor but not (5422). With a 4 card major and 24-26 HCP could respond 1© or 1♠ over 1♣-1¨ as this is forcing, but could easily have (43)33 distribution. So this bid needs it’s own set of responses. With that in mind, we propose to use Baron instead of puppet Stayman. We will also use Baron for any minor suit searches. Responder should only make a move over 3N as a slam try and opener should feel free to raise responder to slam with a fit and a hand suitable for slam.

4♣: Baron 5-8 HCP invitational to slam. Opener bids 4+ card suits up the line, bidding 4N with Clubs as only 4+ card suit. If no fit found, either partner can bid 5N to invite 6N.

4¨: Transfer to Hearts. Opener should super-accept with a good fit.

4©: Transfer to Spades Opener should super-accept with a good fit.

4♠: Transfer to Clubs. 4N by opener shows an unsuitable hand for 6♣ while with a suitable hand bids 6♣ or 6N and a suitable hand but off 2 key cards bid 5♣.

4N: Transfer to Diamonds. Opener can bid 5¨ or 6¨ or possibly 5N or 6N where suitable

5♣:  Super-Gerber

xii) 4♣/4 very strong 6-5+ minor two-suiter, 6 of bid minor
xii) 4N: 27-28 HCP play 3N systems on
