Hi,

playing IMPs, all green you hold in 2nd seat

♠ 105
♥ AKJ10
♦ 72
♣ AK1043

You play a simple 2/1 system, although the issue would also arise
in a standard system context.

The auction develops

(Pass) - 1♣ - (1♠) - 1NT
(Pass) - ???

You are more or less certain (?!), that partner denies a 4 card heart suit,
so the question is, do you make another move?
If it matters, you were prepared to bid 2♥ over 1♠, which may or
may not already answer the question, if you make a move now.

2NT from partner after 2♥ would be Lebensohl / a weak Relais to 3♣.

If the vulnerability affects your decision, please mention it.

With kind regards
Marlowe

I would, for me 1NT shows a little more than a 1S response.

[jdonn]

I'm closer to just bidding 3NT than passing. A 1NT response in competition is not a 6 or lousy 7 count (please no debate from Phil or any Brits, I know it's different for you) and I look to have two great sources of tricks.

Invite.

Hi,

the "Brit" (me) was holding the given hand facing an North American
player, so it should come as no surprise, that 3NT makes, being fairly
cold. I am not good at calculating the percentages, how often it makes,
but it should be way over 50%..

It may have been a more interesting question, if I would have asked,
what to bid with my partners hand:

♠K983
♥952
♦KQ10
♣QJ6

Personnally I find 1NT a bit too heavy for my taste, but I can live with the
decision:

#1 4333 shape
#2 a hand dominated by Queens and Jacks,
i.e. selling the hand as 10HCP is reasonable, and it may well be, that I am
influenced by the fact, that

#1 I know my hand
#2 I am used to play NFB, i.e. I am used to make a neg. X with the given hand
#3 I usually play with a partner who knowes, that he sometimes faces a black
hole, if it comes to acount for missing HCPs.

With kind regards
Marlowe

Pass is not a consideration for me, I lean towards 3N as the decent 5 bagger may easily produce 5 tricks. There are too many minimums partner will pass that give game a good play.

[mtvesuvius]

I'd bid 2NT with partner's hand, which I play as 10-12... However I think I will treat this as 11, since although I'm 4333, I have so many spots.

Pass is no option, the choice is between inviting and bidding (or forcing to) game).

As for Josh's remark about Brits: If many British players play the 1NT response as 6-8 it is related to the notrump range. Or, if they happen to play strong notrump, related to the fact that they grew up in a weak-notrump culture.

[Hanoi5]

That 1NT was sort of heavy. I would have invited with your hand though. The important card was the ♠10, however...

[Wackojack]

Partner should not risk missing game with his 11 count and a likely double spade stop. So respond 2NT. For me a no brainer.

I'd invite here for sure with two likely sources of tricks.
