Hand Evaluation – KCB ( Splinters )

PITBULLS:

          Kantar comes up with a new idea in this article. You can turn the tables on partner when she splinters & answer KCB even when she did not intend the splinter to be KCB !! Just have the understanding that Q bids are not allowed in these specific 4 level sequences so bids are “out of the blue” KCB responses. See his article below.

After a game-forcing major suit splinter agreement,  4NT is RKB.  In some of these splinter sequences the opener can ask for keycards via 4NT or show them via step responses! (Back in the fast lane again)

Consider this sequence:

Opener (you)       Responder
1NT                       2H  (1) 
 2S                        4C, 4D, 4H   (2) 
 ?  

(1) Transfer to spades 
(2)  Singleton in the jump suit, slam try, with at least six spades. 

What do your rebids mean? Here's the latest from the  ward in the psychiatric wing:

A. With no slam interest, sign off in the agreed suit,  bid 4S. 

B. If you wish to take charge, bid 4NT, RKB (1430).  

C. And here's the kicker. With certain hands it might be better to answer the splinter jump by steps treating it as if it were a RKB ask! However, the agreed suit and 4NT are not counted as steps. Also, to pull one of these "role reversals" you must have at least "2 with", the first step. There are actually three steps:     

1st step= "2" with 
2nd step= "3" without
3rd step = "3" with

Why do this? Because some hands (the ones with aces and spaces) are better suited to showing keycards rather than asking for them. Others,  the ones with fillers in the side suits, suits headed by the KQ or KQJ are better suited to asking for keycards because it is easier to count tricks. Can we have our cake and eat it too? Why not?  

A "FILLER" ASK    

Opener     Responder
S. AQ        S. KJ10xxx
H. J10x     H.x
D. KQxx   D. Axx
C. KQxx   C. Axx

1NT          2H (1)
2S             4H (2)
4NT (3)    5D (4)
6S             Pass

(1) Transfer
(2) Singleton slam try
(3) RKB (1430)  opener asking
(4) "3"  

 Opener has a good hand for spades, nothing wasted in hearts, plus fillers in the minors making it easy to count tricks.  

ACES AND SPACES 

Opener     Responder
S. Axx       S. KQJxxx
H. Kxxx    H. Axx
D. Axx      D. x 
C. AJx      C. Kxx

1NT          2H (1)
2S             4D (2)
5C (3)       6S 

(1)  Transfer 
(2)  Singleton slam try 
(3) 2nd step response, showing "3 without". A first step response of 4H  shows "2" with. 4S, to play, and 4NT, RKB, are not counted as steps.  

Opener, with aces and spaces, elects to show keycards rather than ask for them. 

TALK ABOUT THE WRONG HAND 

Opener       Responder
S. KQJx      S. x
H. Jx            H. AQxxxx
D. AQxx      D. Kxx
C. QJx         C. Axx

1NT             2D (1)
2H                3S (2)
3NT (3)        Pass (4)

1. Transfer
2. Singleton slam try
3. To play knowing partner has a singleton spade and six hearts, etc. 
4. Faith

ANOTHER "WRONG" HAND  
    

Opener        Responder
S. Jx             S. AKxxxx
H. KQJx       H. x
D. AQxx       D. Kxx
C. QJx          C. Kxx

1NT              2H (1)
2S                 4H (2)
4S (3)           Pass

(1) Transfer
(2) Singleton slam try
(3) Would like to to in reverse to 3NT, but the rules don't permit it and 4NT is RKB.

TAKING CHARGE

Opener       Responder
S. Kxx         S. Ax
H. Kx           H. AQJxxx
D. AKxxx    D. x
C. Kxx         C. Qxxx

1NT             2D (1)
2H                4D (2)
4NT (3)        5S (4)
6H                Pass

(1) Transfer
(2) Singleton slam try
(3) RKB (1430) opener asking 
(4) 2 with

A reasonable contract. In order to make a singleton slam try in this sequence, responder should have a 6 card suit and at 13 "attractive" HCP, minimum. With a 7 card suit responder can fudge a point or two.

Another  sequence where an ask-show option is possible occurs when responder makes a four level splinter response to an opening bid of 1H or 1S. 

SHOWING OFF YOUR NEW MOVES

Opener        Responder
S. AJxxxx   S. Kxxx
H. QJx         H. Kxxx
D. Axx         D. x
C. x              C. KQJx

1S                4D (1)
4H (2)          4S  (3)
Pass

(1) Singleton diamond, opening bid values
(2) "2" with (10 card fit assured) 
(3)  Two aces missing

Reminder: These suggestions deal only with the  sequences mentioned. (Add others if you like-or junk it all). It's just an idea.
