Here is a hand. I have left the participants names in since the only error, if there was an error, was mine.

Nobody got to 6H although as you can see there are 12 easy tricks.

E cashed his A and switched to a club.I played A and a small heart, so I would have made 6 even if E had a stiff heart. Easy enough.

The hands fit perfectly of course, and maybe it's not a surprise nobody was there.
One was in 6NT, that did not work so well!

 
Perhaps it is worth thinking about what I might have done.
1C-1H
1NT-2S
3H

This seems like a normal beginning.

If I want to try, I have to choose, over 3H,  between 4C and 4D. Bidding 4C is appealing but I am not sure that "bidding around the singleton" applies here. So maybe it has to be 4D. If that elicits 4S from partner we will get to 6H. Should S call 4S over the hypothetical 4D? Well, she could reason "I told him I am limited to 14 hcps and he is still interested, my hand cannot be better than it is. So ok, 4S."
 I did not offer this opportunity, so we will never know.

It occurs to me that I could have bid an nmf 2D over 1NT but I am not sure that's a good idea. Partner would bid 2H, I could show the club fit with 3C but now partner would bid 3S not only with this hand but also with a hand where her club Q is the club 3. In which case I do not want to be in 6.  Of course if I start with nmf and partner bids 3H, not 2H, maybe then we get there.

 The above is equally applicable in Std Am or 2/1 agreements are irrelevant. If Precision folks want to use it to test their agreements, feel free. I assume S opens 1NT in OCP?

A further thought. There is another problem with the nmf auction 1C-1H-1NT-2D-2H-3C.
As most people lay, there are two reasons for bidding nmf. The most frequent is to find a major suit fit. The other is to make a minor suit slam try. So very possible the 3C over 2H would/should be taken as a slam try in clubs, not hearts. Imagine I have a strong hand, interested in slam, with only four hearts but with four clubs. What to do over the 1NT rebid? Nmf followed by 3C is the usual answer. I think the reverse into 2S is the right way to start.

OliverC:
Nice hand, and an instructive one, too.

Game All, Dealer South

North
 !S KQ93
 !H AK1082
 !D Q
 !C K105


South
 !S A64
 !H Q93
 !D J97
 !C AQJ2


1 !C - 1 !H
1NT - 2 !S
3 !H - ??

I think North at fault here, to be honest. The 2 !S bid (a reverse by Responder) is game-forcing in almost any system. That being the case, we should apply the principle of "Fast Arrival" to the 3 !H bid by South, ie: 3 !H is stronger and more encouraging (ie: slam-invitational) than 4 !H would be. That being the case, I feel North should be doing something other than timidly signing off in 4 !H .


At the end of the day what action that is depends largely on your cue-bidding style, but 3 !S or 4 !C must be cue-bids for Hearts (4 !C perhaps more unambiguous). Now when South doesn't show a Diamond Control, the value of North's Diamond singleton becomes apparent and North should have no further difficulty in pushing to the slam. So...

1 !C - 1 !H
1NT - 2 !S
3 !H - 4 !C // Cue
4 !S - 4NT // Spade Cue, no Diamond Control / RKCB
5 !S - 6 !H
All Pass

This.
Though I prefer the 3 !S control, rather than 4 !C.

Also, while the 2 !S bid is almost universally played as a game-force, it does not necessarily promise a five card !H suit. In other words . . . "Fast Arrival" does not apply. The 2 !S rebid could simply be a means to force game while keeping the bidding low.

As an example, picture responder with this hand: !S KQ !H AKJT !D 2 !C KT9876 . . . and, he still goes through the 2 !S GF bid on the way to exploring slam in !C s.

[1] Cuebidding Spades rather than Clubs
The only "problem" with 3 !S is that it might be misconstrued as showing 5-6 in the Majors rather than being a cue-bid for Hearts (and so Partner might just convert to 4 !H or 4 !S not realising it really was a slam try and not you're not sure how to proceed), whereas 4 !C is unmistakeably a cue-bid for Hearts.


[2] 1 !C - 1 !H - 1NT - 2 !S not a reverse
You really believe that? Words fail me! LOL

Are you seriously suggesting that Opener, with 4-card Spades, is going to bid 1NT rather than taking the opportunity to show their Spades at the 1-level? That is such an unconstructive and misleading route to take. I don't actually know of anyone (other than yourself) who has ever suggested that it's a remotely sensible methodology.

Some people will even take this further and take the view that 1 !C -1 !H -1NT-2 !S is always showing 5-6 in the Majors, on the basis that with 4-5, there's no real point in showing the Spades, because the 1NT rebid by Opener effectively denies having a 4-card Spade suit.

Whether you go that far or not, showing a Major suit at the 1-level is far more important than showing a balanced hand with <15 hcp. If Responder has a relatively weak hand with 4-4 in the Majors, and Opener follows your methodology, you'll inevitably end up playing in 1NT rather than 2 !S when you have a 4-4 Spade fit and 2 !S is inevitably going to be a safer contract. That is just plain silly (and precisely the reason why nobody does as you suggest).


That being the case I think the vast majority of people who accept and use the principle of fast arrival would agree 100% that it applies here.


[3] Reverse into !S with !S KQ, !H AKJT, !D 2, !C K109876
Hmmmm. I must confess that were I playing 2/1 (which I do occasionally despite my preference for Super-Precision) it would never remotely occur to me to completely misrepresent my hand by responding 1 !H with that lot and then reverse into a 2-card Spade suit solely as a means of creating a GF sequence. How do you expect Partner to make the right decisions on any hand if you're not prepared to try to have a sensible bidding conversation where you show what you have and Partner shows what they have?

Seriously, I'd be more likely to bid an inverted 2 !C and then show the Hearts later. Yes, you're "not supposed to do that" with inverted Minors, but it's less of a perversion of your hand description than reversing into Spades (and suggesting 4-5 in the Majors in the process when you are actually 4-2 and have 6-card support for Opener's first bid suit). You are now also suggesting delaying your support for Partner's Clubs until you're at the 4-level, which seriously restricts your space for slam exploration, especially since you've probably got Partner hopelessly confused, thinking you've been dealt 17 cards :)

I think we have just established the usefulness of this Forum!

It would never occur to me to bid 2S over 1NT without five hearts. I think the 5-4 shape is enough though. It's true that I do not expect to be playing in spades but bidding out shape often helps find the right contract. I am not so sure that 4C over 3H shows three clubs, and thus inferentially a stiff D, but perhaps so. At any rate it certainly shows slam interest. And would quite possibly, on the logic mentioned in my OP,  produce a 4S call from opener, and now we are on our way.

As noted, I felt comfortable posting all names as surely my 4H over 3H ends the auction. If I had chosen differently, maybe we reacj 6H. I didn't..

I am looking forward to putting up some more hands. Maybe someone else would like to do so as well?

The club slam try hand of Masse:
By coincidence, I had discussed this with my StdAm partner today. We begin  1C-1H-1NT-2D

The nmf call of 2D is used in either of two situations. Search for a major suit fit OR minor suit slam try. With the Masse hand it goes 1C-1H-1NT-2D-whatever-3C. This is a slam try in clubs, whether or not opener showed three hearts in response to 2D.
 
Btw. Joe's write up uses Walsh responses to 1C. I believe 2 way nmf, where both 2C and 2D are artificial,  is particularly useful when Walsh is being played. After 1C-1H-1NT responder might well have long diamonds, and of course his strength is not yet known. In 2 way nmf, a bid of 2C over 1m-1M-1NT forces opener to bid 2D, and with a weak diamond hand responder then passes, with an invitational diamond hand he bids 3D. With a forcing D hand he starts not with 2C but with a gf 2D and then bids 3D. There are many other sequences.
There is a nice write-up at

and of course in many other places.
