Yes, but E and W would have opened first

[Tramticket]

MPs? IMPs? Rubber Bridge?

But I vote yes, unless rubber bridge.

[pescetom]

Reluctantly I would pass.

[rmnka447]

I would pass also.

[croquetfan]

must rebid 2C over partners 1NT, then do you then pass partner's 2H? Impossible to know, so must pass unless you are doing so badly you need a top and prepared to risk a disaster.

[dsLawsd]

Probably but that depends on system, type of event, quality of players in the event.

In rubber bridge, do I or E-W have a game or part score on?
IF they have a game on, then open to kill the vul if playing Chicago.
Open if we have a part score on. Etc.

These days it seems everyone bids on air...

[dil21]

Obey Pearson’s rule.

[LBengtsson]

How does Pearson evaluate a singleton King?

[palpal901]

do not open: unlikely to gain more than 1 of a suit and partner will expect this to be a stronger suit openning than seat 4 in fact has: his partner may reply too strongly and this will result in going down: the short suit could result in immediate loss to the ace and this would send a clear message to the holder of the queen in the suit.

[Winstonm]

I open. Little downside risk. Game is not out of the question. I have some defense. Partscores count, too.

[pjmingola]

I think Larry Cohen has a good rule for opening borderline hands in fourth seat: If you're playing against two of the top players at your local club and expect to get slapped around in the auction/by defense, pass. If you're playing against a pair who will let you pick up a few extra tricks, will overbid to compete, or will not push your bidding too high, open.

[apollo1201]

Yes, only with a disciplined partner who won’t get unreasonably to the 3-level. And contrary to others, I am passing partner’s 1NT rebid. She could easily have a few H. And rebidding 2C is going to land me in a precarious 2S in 5-2 with the main suit headed by the 8.

[mkkisiel]

Yes, because we would use Drury

[BillPatch]

Playing ACOL I would rebid 2♣ over a 1NT response. In ACOL I would not have shown 5 spades minimum until my rebid which would also show at least 4 clubs. Unless we had found an 8 card fit in spades partner would probably in a 4-4 club fit by passing or more rarely raising. Failing that partner would likely bid a five card or longer red suit. Only if the distribution is exactly 2=4=4=3 will responder usually preference back from the assumed seven card club fit to the assumed seven card 5-2 fit. Since the 1 NT response would promise 6 to 9 HCP points and the opponents not commonly 12, usually no more than 11 HCP, the 1 NT bidder usually has 9 or 8 HCP. I NT with 18 or 19 HCP is rarely a plus score. An 8 card fit improves the odds of success.

In a 5 card major system which utilizes the forcing or semi-forcing NT response to an unpassed major it would be unwise to disturb the 1 NT response. Almost half of the responses are in the ten to 12 point range. with 21 to 23 HCP the declaring side will win a majority of their 1 NT contracts. Since five card mars are assumed, standard 2 over 1 systems automatically raise a major immediately with 3 or more card support, so you will have already found all your spade fits. In addition the 2 ♣ rebid only shows 3 or more(rarely 2), and it is common to bid 2 clubs with an intermediate range 6 card suit playable with 2 but not a singleton, responder will usually give a false preference with 2 cards in spades, raise to 2 NT with many other balanced hands with 2 card in spades, and only raise clubs with a 4 card support with a singleton or void in spades, and five + club support unsuitable for a 2NT rebid. Also responder will usually bid their highest 5 card red suit, usually in hearts for a 6 card fit. So the 2 club rebid only improves the contract on about half of the hands without 2 cards in spades, and 90 percent of the more common 2 card spade fits play in the 5-2 spade semi-fit with that dreadful spade suit, a 5-1 heart fit, or contract for 2NT. A 2♣ rebid usually results in a worse contract in 2/1 over 75 % of the time a opposed to passing the 1NT response.

Sir we play reverse Drury so partner uses the 2C bid, bid 2S,or bid 1NT depending upon his holdings.I have a rebid of 2C over his 1NT.We very rarely pass a hand holding 2 ACES and a KING.We have the 5 carder spade suit where partner may compete at the lowest suit level for a part score.Where partner bids 1NT and then bids 2D/H/S,I shall Pass that.Apparently the remaining 29 HCP must be 10/10/9 and without a 6 carder suit else that someone would have called.I also know that quite a few will open 1S and pass partners 1NT.

[miamijd]

Seems like a normal 1S fourth-seat opener.

[rmbonger]

Yes. I would.

[Dinarius]

A wretched 8 loser 11 count?

Yes, it passes rule of 20, but badly.

It’s one of those hands where if you pass at MPs and score well you talk about it in the bar afterwards. And, if you bid 1♠️ and go for 200, you also talk about it afterwards.

Seriously, it guesswork. But, what’s my rebid? Exactly.

So, I pass.
