You are playing with an expert, you have discussed responsive doubles, but do not have clear agreement about this auction. What would you expect the 2nd X to show?

Dbl = I want to compete but don't know in which suit. Usually it's not with ♥, so it suggests minors.

[menggq]

2N=JORDAN means S4 FIT
X =RESP DBL shows minors

[aguahombre]

Unless someone is messing around, there are not enough points in the deck to need a general value call. Perhaps this double should be part of a package, including 3S and 3NT in addition to the double --each suggesting different distributions.

X=less extreme (minors)
3NT=extreme in minors
3S=4H and a 6+minor?

[whereagles]

2NT in this position can be pretty low on hcp, so I'd say this is roughly equivalent to

1M dbl 3M dbl.

[jogs]

Was 2NT some type of spade raise?
Double is hand wanting to compete with exactly 3 hearts.
2=3=4=4 most likely pattern.
With fewer hearts advancer should have a suit worth
bidding.

I do not understand this 4-4 minors opinions. 2NT bid is forcing to 3♠, why shd i show 4-4 minors ? This DBL means 2NT bidder is full of ..it ! Or the opener opened with a very light hand. If i have 5-4 5-5 minors i can always bid 3 nt.

Often the case is 2 NT is alerted as limit or better but usually what we see is 7-9 hcp with a stiff (sometimes even lighter)

I will DBL with all balanced and 10 + hcps, regardless of holding 4♥+4m, 4-4 minors, or 4333 any 4 card suit. I am not bidding 3♥ here with only 4. Pd will never know when to bid 5♥ or pass or DBL if we do this both with 4♥ 9-10 hcp and weak unbalanced hands with longer ♥ IMO.

As originally defined, 7-9hcp plus a singleton is a limit raise!

Opener may have opened light, responder may have invited light. So we can have some part score or game for our side. Nobody says 3♠ makes, but it usually won't be defeated many tricks. 3♠x-1 is only +100, while 4m= is +130. Dbl also shows values so we can still penalize opps, bid 3NT,...

Yes, but people here seems to think pd will not have enough to make a "general strength" values. Which is incorrect.

AQxxx

JTxx

was a LROB for my opponents

Axxx
QTx
QTx
Axx

is also a LROB, when pd doubles 2NT you know LROB is something like the 1st example or as i said earlier even lighter if they are messing with you. My point is, it seems to me that late fashion is to bid 2 NT first with a lot of hands that used to bid 4 major in the past.

Of course its responsive.

(edit) but I would not characterize the poll choices as being mutually exclusive. A responsive double can include a hand with both minors. It can also include a balanced hand with some points that wants to 'compete'.
