Kings inquiry activation following RKCB and Dynamic meaning to Kings Inquiry

Suppose you play RKCB and always activate it by bidding 4NT.  i.e. you do not play kickback.While not playing kickback bidding space is a problem.

RKCB is combined with Kings Inquiry and Inquiry for Q of trump suit. Kings Inquiry can be played as "Specific Kings" or as "Kings Quantity". Kings Inquiry if made by bidding 5NT is perfect when you play in .

When trump suit is and Kings Inquiry is defined as specific kings – space allows showing any king responder has.

When trump suit is H and specific kings is activated by bidding 5NT responder has no way to show king of spade unless he bid 6 which might be too high.

Obviously when trump suit is minor suit the problem is even more serious.

We can see that whenever Kings Inquiry can be made by bidding 5 in trump suit + 1 (or lower) we have no space problem.

In order to save bidding space I suggest that following the initial response to 4NT the cheapest bid which is not trump suit and which is not Q ask should be interpreted as Kings Inquiry.

Examples:

Trump suit is : 4NT-5-5 is kings inquiry (Q inquiry was skipped)

Trump suit is : 4NT-5-5NT is kings inquiry

Trump suit is : 4NT-5-5 is kings inquiry

Trump suit is : 4NT-5-5 is kings Inquiry (Q inquiry was skipped)

Trump suit is : 4NT-5-5NT is kings Inquiry

Trump suit is : 4NT-5-5 is kings Inquiry (Q inquiry was skipped)

Trump suit is : 4NT-5-5 is kings Inquiry (Q inquiry was skipped)

Trump suit is : 4NT-5-5 is kings Inquiry

Trump suit is : 4NT-5-5NT is kings Inquiry

Trump suit is L: 4NT-5-5 is kings Inquiry (Q inquiry was skipped)

Trump suit is L: 4NT-5-5 is kings Inquiry (Q inquiry was skipped)

Trump suit is L: 4NT-5-5 is kings Inquiry

Trump suit is L: 4NT-5-5NT is kings Inquiry

The above structure saves bidding space and as long as the bid which activates Kings Inquiry is not higher than 5 in trump + 1 Specific Kings works perfect.

I wonder, if bidding space is not big enough to show all kings is not it smarter to play Kings quantity and not specific kings ? or do you have other suggestions ?
