 Hand Evaluation - KCB ( Minors at 4 level )

 

PITBULLS:

 

            O.K. Kantar has got to me . He advocates “Kickback” when the partnership has just found a minor fit at the 4 level . I like this because 4NT being natural is a bonus . Kickback is bidding the cheapest available bid after the minor fit . Kickback extends to the next ranking suit when the suit has been bid previously .

 

Kickback is a dangerous convention because you have years of using the bid as a Q bid. Old habits are hard to break especially for old guys. Using it only after 4 level minor agreements makes sense to me.The 4 level is the agreement but not the ask for minors. When you have just found ( agreed ) your minor fit by the 4 level,  you need something to be KCB. Use Kickback not 4NT. 4NT & the minors is a terrible mix.

My feeling ( Kantar ) is that in sequences when a second bid minor suit is introduced for the first time suit at the three level there should be no immediate keycard ask available in that minor.   Must support partner first at the 4 level ( the agreement )  and Kickback is KCB .

Four diamonds is not RKB because it is a first bid suit.    In this sequence 4H is RKB.

In the preceding example, the response to the queen ask would be 4NT, denying the queen.   Opener should correct to 5C, but at least has the option of passing.

(1)The agreement.
(2) RKB
(3) 1
(4) Queen-ask.
(5) Yes with DK.

Once RKB is in motion, the RKB bidder frequently uses a previously bid suit as the queen-ask.   However, facing a 0 or 1 response, a return to the asker's  first bid
