Bidding after a positive minor suit response


1.1.1.  2C Response to 1C, +ve 5+ Diamonds


POSITIVE 2♣: transfer to Diamonds showing 8+ HCP and a five+ card suit GF. From a passed hand shows 7-10(11) HCP.

               2: showing a balanced hand 2-3 diamonds any strength or 4414 distribution and 19+ HCP (20 in 3rd/4th)

                               2/2♠/3♣: 4 card suit or 5 card suit but 8-10 HCP

                               2NT: 12-14 HCP 5d332 (10-(11) PH)

                               3: 6+ Diamonds(without a 4 card suit)

                                    3: ask; 3♠: 6 Diamonds, 3NT: 7 Diamonds, 4♣: 8 Diamonds, 4: 9+ Diamonds

                               3/3/3♠: 5 card suit with 12+ HCP

                               3NT 9-11 HCP 5d332 (7-9 PH)

                               4NT(quantitative): 15-16 HCP 5d332

            For the brave, invert 2♠/2NT and 3♠/3NT responses to right-side NT contracts.

               2: SAB Natural five+ card suit

                               3N: Special SAB response showing 2 of major suit asked and balanced 11-13 HCP

               2♠: SAB Natural five+ card suit

                               3N: Special SAB response showing 2 of major suit asked and balanced 11-13 HCP

               2NT: is 30/14 ask for Diamonds and sets trump. Usually 4+ Diamond support.

               3♣: SAB Natural five+ card suit

                        One sequence requires special attention. After 3 which shows 11+ without Club support. To show Hearts you would have to bid 4, this would normally be forcing but here responder can correct to 4NT or 5♣ with only three Hearts. This method can be used in other sequences where opener has been shut out of showing a 4 card major.

                               3NT: 4th Step Special Response shows 12-14 HCP 3325d distribution.

                                    4♣/4: Keycard for minor suit bid

               3: 4 card support with mild slam interest, usually 17-18 HCP balancedcue-bidding suggested

               3/3♠/4♣: A strong hand with a solid or semi-solid suit ask for cue-bidding, see 19.6

               3NT: 16-18 HCP 4414 dist. with singleton diamond, non-forcing. (17-19 in 3rd/4th)

               4/4♠/5♣: 156-18 HCP, 4+ support, singleton or void in suit bid

Should a fit be found even through SAB, if opener bids the agreed suit below 3NT this is RKCB 30/14. This can occur even late into an auction. 
Example Hands:

1.1.2.  2D Response to 1C, 8-13 HCP balanced




2: 8-13 HCP balanced GF, only (4333) hands, hands with 4 Clubs and Diamnds or 9-10 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 3NT rather than continuing the relay with no hope for slam. Other non-jump bids(with 2NT 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 3NT 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
               2NT: 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
                               3NT: poor 5 Diamonds 5d332                 
               2NT: 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
                                              3NT: 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.)
               2NT: 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
2NT: 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
               3NT: 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
               3NT: 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, 3NT: 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)
3NT: to play, no slam interest.
