Improving Queen Ask after RKCB

Source: www.vba.asn.au
The standard responses to 0314 RKCB are as follows:
4![]() |
4NT | Assume ![]() |
5![]() |
0-3 | |
5![]() |
1-4 | |
5![]() |
2 (or 5) without ![]() |
|
5![]() |
2 (or 5) with ![]() |
After 5 or 5
, a step bid is then used as a trump queen ask. The standard responses to these are:
4![]() |
4NT | Assume ![]() |
5![]() |
5![]() |
5![]() ![]() |
5![]() |
No ![]() |
|
5NT | ? I don’t know what’s “standard” | |
6![]() |
![]() ![]() |
|
6![]() |
![]() ![]() |
|
6![]() |
![]() ![]() |
|
6![]() |
![]() |
There are two major problems with this:
(1) 5NT is not utilised.
(2) If opener bids 6 with
Q and no other Kings, how can responder investigate a potential grand if responder wanted to ask about 3rd round controls (such as a vital Queen in a side suit, or maybe a doubleton)?
I am uncertain as to why 6 is taught as the bid to show the
Q with no side kings because it doesn’t make much sense to destroy so much bidding space when responder could be looking for a grand even without the aid of other kings.
A much better improvement would be to use the 5NT bid as the “Q with no other Kings” so responder still has all of the 6-level bidding to investigate third round controls. No doubt this is not the “best” version of RKCB available but it is certainly a better improvement than what the standard/default responses are.
