There's one other method that I've seen, described by Marshall Miles in Bridge From The Top. Opener shows his suitability in steps: bad, average, good, excellent. Then responder can sign off in 4NT or one of the trump suits (except opposite the "excellent" hand), or he can bid a new suit as a keycard-ask. Miles suggests a numerical method where aces and key kings are 2 and key queens are 1, but you could play two-suits Keycard instead, or you could have responder show how many keycards he has.

Seems like a no brainer to play this unless you do something else very useful with your 3D 3H 3S (I have heard of some people playing that it shows a 4 card minor with 4m direct showing 5 which also seems very good).

When I first designed this part of the system, this is roughly what I put in. However, I now think the transfers are simply better. There is an added bonus for me in that this also mirrors precisely what I like to play over a 1NT opening. Incidentally, I think there is a reasonable argument to drop 3 Smolen after a 2NT opening, since this sequence can usefully be employed to help with probing for minor suit slams, whereas the 54 hand is comparatively easy to handle elsewhere.

But how would you bid it ? ( I assume using your transfer method ) ?

How about

2NT - 3;
3 - 4 (diamonds);
4 - 4 (RKCB);
4 - 5 (K ask);
5 - 5 (SSA);
6 - 7?

At this point I'd be trying to decide between 7 and 7NT. With diamonds 3-2 and hearts 4-2/3-3 we can count 13 tricks in diamonds unless partner has specifically AJxx Ax KJxx AQJx, but even opposite that 7 is pretty good.

Finding 7NT when it's right is tricky, because it will usually depend on whether partner has J as well as some extra black-suit winners. For example, opposite AQxx AJ Kxxx AKxx we want to play 7NT, but opposite either AQxx Ax KJxx AKxx or AJxx AJ Kxxx AQJx we should be in 7.

You missed the context Phil. Frances' question was how to bid the hand if making a transfer and showing a second suit promised at least 5-5.

In the sequence I gave, Opener has denied a side king and shown the Q so several of these hands are not possible.

Yes. I wasn't discussing the auction you'd have opposite that specific opening hand, where all roads lead to 7. My point was that if you are opposite a hand where 7NT is right, it's hard to fnd out about it.

For example, in your auction, if responder shows K, you still won't know whether to play 7 or 7NT, because it depends on whether opener has J.

Or, after opener denied a king, he might have had AQJx AJ Kxxx AJxx, where 7NT is about 95% but 7 is a mere 68%. Maybe opener would convert to 7NT with this, though.

Yes, you are right about this. Do you have any suggestions? Aside from adding a step for QJ to the SSA (which has its own problems) it is difficult to see any way of getting the required information here outside of having started 1 and relayed (which is a little bit more than a small tweak).

Asking bids after Keycard aren't really my speciality, but it seems to me that in this auction the red-suit jacks are more important than the black-suit queens. For the specific case of a two-suiter opposite a balanced hand perhaps you should change the meaning of one of your new-suit bids, eg 5 in your auction. Or if you were playing spirals you could change the order to something like: keycards, queen of trumps, long side-suit king, short side-suit kings, long side-suit queen, jack of trumps, long side-suit jack.

I can vaguely remember Phil telling me about asking for the jack of trumps, in about 1990, so maybe he's already got a set of rules to cover this.
