on this webpage search Kickback or asking bid other than 4NT
The question is my partner introduced me this convention a few month ago and we did practice some hands on this convention(with various slam try sequence). I do feel now we can avoid bidding a minor slam which two keycards are missing. However I also notice a new problem. It seems to me this convention save some space on key card asking but deprive some space on cue-bid. During bidding practice quite a few times my partner and I find, let's say, ♣
fit at 4 level, now 4♦ is key card asking but I care more about ♦ controll than total number of key cards, and we finally bid a slam with only 1 key card missing but lacking 2nd round control in ♦.

Is the problem due to natural disadvantage of the convention or my personal misunderstanding
of some basic concept of slam bidding?
