We play a version of 2/1 with inverted minors. In a practice bidding session, my partner opened 1D and I had A x QJXXXX AKJXX. I bid 4N and immediately got into an argument. I was hoping it was taken as KCB, but from what I could find it is BW. Most inverted minor raise auctions are looking for a NT game. Is 4N quantitative, BW or KCB? Is there a standard meaning to this bid?

Obviously the most important part is to have agreement on what it is (regardless of what others play). But as far as I know, the default meaning for 1X-4NT is ace-asking. I don't remember ever having a hand for that bid, but it makes sense to me -- if you want to RKC, you can set the trump first, using whatever forcing raise is available to you.

[TWO4BRIDGE]

Use 1m - 4m! = RKC

And 1m - 4NT as "Specific Ace Ask " ( Google it )

Some might well choose 1♦-4N as quantitative. For instance, imagine you have a hand like:

AQx AQT KJx JTxx

Over 1♦ you don't have great responses. You can bid 2♣ but that doesn't really suit your hand with such a bad 4 card suit and a flat hand. You can try an inverted raise but that is a bit of a stretch as you don't really want to suggest a diamond fit opposite 4 or even many 5 card suits. With the same hand and no major Q you might well respond 3nt which many play as a flat 13-15. With this 17 count though you might well be interested in slam in NT or diamonds depending on if partner has extra values and if partner is flatish or shapely.

[bucky]

Yes, I think 1♦-4NT being quantitative is a useful treatment, if 1♦-2NT is not forcing in your system.

1x 4NT = Bwood

1x set the suit then 4nt = KC

Those are the rules we used.

[P_Marlowe]

RKCB.

Is there a standard meaning: no.

What would I take the bid for: RKCB.

Either my p is not advanced enough, or my p thinks I am not advanced enough, fairly
safe bet that it was meant to be RKCB without prior discussion.

With kind regards

1X-4NT is never RKC for me. With a fit you have time to just support and continue with 4NT afterwards. Without a fit and quantitative you can bid a suit first and see what happens. All that's left is regular Blacky, asking for Aces (maybe specific).
