Bidding after a positive balanced response 2D & 2NT


1.1.1.  2D Response to 1C, 8-13 HCP balanced


 

2: 8-13 HCP balanced GF, only (4333) hands, hands with 4 Clubs and Diamonds or 8-10 HCP and weak 5-card minor. 7-10(11) HCP from a passed hand and where it is referred to as 8-10 HCP range 7-8 HCP is used for a passed hand and 9-10(11) HCP where 11-13 HCP is referred . Yes, responder can have a 4-card major if 4333 or 3433 distribution. Opener will often relay with 2 to find exact distribution and HCP range.  After a 2 relay a 2♠ response showing any 8-10 HCP after which opener may just jump to 3N rather than continuing the relay with no hope for slam. Other non-jump bids(with 2N showing Hearts) are either a 6+ card suit or a hand that is 5+ of a major and 5+ side suit or a 5 card suit where 3N has problems or possibly (5332) hands where trump quality is the deciding factor in slam decisions. There is very little reason not to get the responder’s distribution and HCP and this knowledge could be useful for slams or choice of game contracts.
2: Relay for distribution and HCP range
               2♠: 8-10 HCP any hand
               2N: relay for dist.;
                               3♣: 4 Clubs 4 Diamonds
                                              3:  relay for exact distribution
                                                             3: 4 Clubs 4 Diamonds 3 Hearts 2344
                                                             3♠: 4 Clubs 4 Diamonds 3 Spades 3244
                              3: 4 Hearts 3433
                               3: 4 Spades 4333, 
                               3♠: poor 5 Clubs 5c332
                               3N: poor 5 Diamonds 5d332                   
               2N: 11-13 HCP 4 Clubs 4 Diamonds
                               3♣: relay; 
                                              3: 3 Hearts 4 Clubs 4 Diamonds 2344 
                                              3: 3 Spades 4 Clubs 4 Diamonds 3244 
                                              3♠: 4 Clubs 3334
                                              3N: 4 Diamonds 3343
               3♣: 11-13 HCP 4 Clubs 3334.
               3: 11-13 HCP 4 Hearts 3433.
               3: 11-13 HCP 4 Spades 4333
               3♠: 11-13 HCP 4 Diamonds 3343
After 2 opener can obtain the exact distribution of responder except in the case of a poor minor 5m332 with 8-10 HCP. Opener now uses 4♣ as a puppet to 4then next bid is Kickback 30/14 or bids 4: as Kickback 30/14 for Clubs, see section 19.7. Opener does not have to get all the distribution before using 4♣/4 from sec. 19.7, this may avoid wrong-siding contract or giving unnecessary information away.

If responder is an unpassed hand SAB is used for 2 of a suit. Otherwise, the next four bids responder shows degree of support.

2♠: 5+ Spades SAB after 1st/2nd seat opening, asks for trump holding otherwise(below). (Should be used where opener knows to play in Spades or NT or possibly even in a second suit if they find responder with 2 Spades. There will be little room to explore so a second suit should be a good 5 card suit.)
               2N: 2 Spades
               3♣: 3 Spades JT9 or worse
               3: 3 Spades Q32 or better
               3: 4 Spades JT98 or worse
               3♠: 4 Spades Q432 or better
2N: 5+ Hearts SAB after 1st/2nd seat opening, asks for trump holding otherwise(below). (should know where auction is going)
               3♣: 2 Hearts
               3: 3 Hearts JT9 or worse
               3: 3 Hearts Q32 or better
               3♠: 4 Hearts JT98 or worse
               3N: 4 Hearts Q432 or better     
3♣: 5+ Clubs SAB after 1st/2nd seat opening, asks for trump holding otherwise(below). (should know where auction is going)
               3: 2 Clubs
               3: 3 Clubs JT9 or worse
               3♠: 3 Clubs to Q32 or better or 4 Clubs JT98 or worse
               3N: 4 Clubs Q432 or better
3: 5+ Diamonds SAB after 1st/2nd seat opening, asks for trump holding otherwise(below). (should know where auction is going as little information is obtained, so could just get distribution)
               3: 2 Diamonds, 3♠: 3 Diamonds, 3N: 4 Diamonds
For the above bids 4♣ as a relay for 30/14 in other suits and 4: as 30/14 for Clubs (see sec. 19.7)
3/3♠/4♣/4: A strong hand with a solid or semi-solid suit ask for cue-bidding (see sec.19.6)
3N: to play, no slam interest.


1.1.1.  2N Response to 1C, 14+ HCP flat


BALANCED POSITIVE 2 NT, 14+ HCP flat with no 5-card suit, with 5332 always make a positive response in that suit. With such high card strength can safely bid to 4N, so partnership is forced to 4N or 5 of suit.
3§: Baron, bid four card suits, up the line

3¨: 4 Diamonds, could have another four card suit

            3©: 4 Hearts, could have four Spades or Clubs

            3ª: 4 Spades, could have four Clubs

            3N: 4 Clubs, exactly 3334 shape  

 3/3/3♠: natural, five plus cards; not an asking bid; invites cue bids

             Raise with 3 card support; q-bid with four cards; bid 3N w/two card support

3N: 5+ Clubs, F1, similar to above, but bid 4N w/two card support
4§: Gerber
4: Show your HCP count in steps of 1, 4=14, 4♠=15 4N=16 etc.
