You play 4 suit transfer and partner starts with Stayman.
If 4NT is RKC: you play 41/30.
What do you bid now?
(Partner did mean the bid different then I understood it)

Looks like rkcb. I am responding according to the state of the matter that I hold 3 keycards.

Partner didn't like the 500+ penalty in 4S.
Did double of 2S promise 4xH? Or primes? Else?
What would pass mean? Not 4xH? Typical 1NT? Stay out the way?
What would 3C instead mean? Liking offense?
I'm expecting S:Qxxx and 5xgood diamonds - source of tricks.

If this auction has promised a heart fit I suppose it could be RKC for hearts.

I don't think it can show minors.

Anyway, I would take 4NT as to play.

Pass would mean: nothing extra to say. Most hand without 4cH.

Yes, A good hand with Good 5cC or 6cC

Why 5cD and not C?

So why partner didn't bid 3NT a round before if he wants to play 3NT now ?
If he is too strong, why didn't he bid 4NT ?

He was asking for a spade stopper which he didn't have himself. Now that we have it, he wants to play 4NT. He has a good 6-card minor along with his four hearts.

Now we are told that South's double shows four hearts. Then I suppose 4NT is RKC for hearts.

RKC for hearts. This auction is in the same genre as 1 - 4 - 4N.

We didn't 100% agree that DBL shows 4cH, but if DBL is takeout then it logically shows 4cH?

The main question here is: does partner promisse a 4 card M or not? Also, what are responder's other options with strong balanced hands, especially without 4M?

If this is real stayman (promissing a 4 card M), then we have a fit, which means 4NT is RKC and we have 3 keycards. I'll bid 5.

Did you agree that Dbl is takeout even?

No, you can have a maximum 2=3=4=4 for example...

My partner intended 4NT for the minors and I thought it was RKC for Hearts.
My partner started with 2 and wanted to follow that with 3 as minor suit stayman.

What was wrong with 3 over 2, planning to bid 4 later on?

I don't think "take-out" is a good definition of this double.

If it doesn't promise four hearts then it is not clear if 3 from North would be forcing. Of course if you play non-promissory Stayman then 3 shouldn't be forcing anyway, what else can North do with a 2353 8-count.

Btw, what would 2NT by North in response to the double mean?

We didn't have a 100% agreement that DBL promises 4c, but we would both expect it to be 4c.
I would take 3 from my partner as forcing, my partner wasn't sure of that.
We played 4-way transfers (1NT-2NT transfer to ), so 2 does not always promise a 4cMajor with an invitational hand.
I would take 2NT after the DBL as to play.

Let me get this straight.
If there had been NO interference, is your Minor Suit Stayman forcing ? ( ...or can 3C be passed ? ) .
1NT - 2C
2H - 3C! = MSS, forcing ?

If so, would 3C! ( by Responder ) over partner's DBL ( showing Hts), still mean the same in this interference auction ?

[ In otherwords is your MSS "system still ON" over 2-level interference ?? ]

We didn't really agree MSS, but I would take 3 as forcing; also after the interference I would take 3 as forcing.
But I don't think that in either case I would take it is as MSS after I showed .
...Probably not a good problem for the forum, given all these uncertainties.

yeah, probably better first to work out what the double means and what the follow-ups are. Then it might be easier to decide on the meaning of 4NT afterwards.
