(2♥)-4♣-(Pass)-4NT

4♣=5c♣, 5c♠, good hand
4NT=RKC, 6 aces

What answers do you use, especially to show Q's or voids?

Similar, but void not possible:
1NT-3♥ (3♥:3=1=4/5)
4♥-4NT (4♥=asks 5c-minor, good hand // 4NT=RKC,6 aces)
?

Note: Our answers on 4NT with 5 aces:
5♣=41
5♦=30
5♥=2, without Q
5♠=2 with Q
5NT=even number of aces and a void
6x=odd number of aces and a void

I suggest the higher ranking Q in the first reply to 6 Ace .
I then roll the lower ranking Q into the K-ask ( specific replies ):

1) (2♥)-4♣-(Pass)-4NT :
4NT = 6 Ace for ♠ & ♣

5C = 0/3
5D = 1/4
5H = 2 - ♠Q
5S = 2 + ♠Q

a) Let's say 4NT got the 5C reply ( 0/3 ),
then: 5D = ♠Q-ask:

5H = ♠Q + ♥K
5S = no ♠Q
5NT = ♠Q + ♦K ( NT shows feature of asking suit, ♦ ), no ♥K
6C = ♠Q + ♣Q but no ♥K or ♦K
6S = ♠Q but no ♥K or ♦K or ♣Q

b) Let's say K-ask after 4NT got the 5C reply,
then 5NT = K-ask :

6C = ♣Q
6D = ♦K but no ♣Q
6H = ♥K but no ♦K or ♣Q
6S = no outside K or ♣Q

Playing 6 aces is technically highly questionable. I can see the attraction - you want keycard available for both suits, but it is hopeless when responder is short in one of our suits, and it leaves ambiguity over strain, which hurts follow up bids (my eyes are still bleeding from reading the first response, for instance).

Other solutions are available.

There are several response schemes available. Probably the most common method is for a (single) suit to be agreed but for the king of the other suit to be included as a key card. For example, you might play that 4♥ is a 6KCB ask with diamonds agreed (but including ♠K) and 4NT is a 6KCB ask with spades agreed (but including ♣K). I do not think I would recommend this though. If you did this then the answers over 4NT are simple:

5♣ = 1 or 4
5♦ = 0 or 3
5♥ = 2 or 5 without ♠Q
5♠ = 2 or 5 with ♠Q
5NT = even + void
6m = odd + void

You would subsequently treat the ♣Q as the king in follow-ups.

Similarly, over 4♥:

4♠ = 1 or 4
4NT = 0 or 3
5♣ = 2 or 5 without ♣Q
5♦ = 2 or 5 with ♣Q
5♥ = even + void
5♠/5NT = odd + void

I read on the forum a couple of years ago, that you can answer 0 queens, 1 queen. If you happen to have 2 queens you answer 0 and add a keycard to your hand. This is obviously dangerous on some hands and I wouldn't recomend it, but I though it was a funny simple smart way to deal with it.


The optimal strategy will vary on context, since sometimes one queen is useless (5-5 opposite 4-2), others both are golden (5-5 opposite 3-3).

Focusing on one and using the other as a side king sounds best for me, this allow partner to use evaluation for extra trumps as queen etc, however this creates problems as to wich one, sometimes it is obvious wich one to use since partner has shown doubleton in one of the suits (1NT-2H-2S-3m-3NT-4m) but other cases are harded and should be solved with some rules. My recomendation:

-When both suits are shown at the same time and none raised (your example) use the major (avoids ambiguity when singing off at 5 level)
-When suits have been shown at different stages (1NT-2H-2P-3C) use the one that has been explicity raised, otherwise use the second one to be shown.
