1D (1H) ?

[straube]

We play an artificial 1D (10-15 w/ 0+ diamonds).

Over 1H interference we play

 

dbl-negative or GF with a suit

1S-5 spades

1N-natural

2m-nf

2H-undiscussed but probably GF cue asking for stopper

2S-weak

2N-weak, minors

3m-weak

 

so I'm responder and hold xxx Ax xxxx AKxx

 

1N shows a stopper and as many as 11, but this is a nice 11 and I don't really want to declare.

I chose dbl and hoped to raise 1N to 2N.

 

Seems like we need better ways to sort out minors and balanced hands. We don't have enough ways to force

 

How about

 

dbl-spades

1S-suggests NT or could be competitive with a minor

1N-natural

2C-forcing

2D-forcing

2H-another spade hand?

2S-weak

2N-minors

Somewhat off-topic, but am I right in thinking that artificial continuations (e.g. 1S denies spades) in this auction are not GCC legal in the ACBL, even when 1D is artificial (10-15, 0+ diamonds)?

[Jlall]

Yeah I got penalized once in the national fast pairs for playing 1S=denies spades....I guess it was a national GCC event!

 

Straube, your suggested sequence is very common/good. I'd recommend keeping 2N natural though (sometimes you want to play from your side), and using 3C for both minors.

 

Also, use X=4-5 spades, 2H=6+ spades constructive or better, 2S=6+ spades weak.

[Cascade]

Over a symmetric 1♦ which always has a major we play a negative double emphasizes the minors.

[Jlall]

If you are playing GCC you can just play the same thing with 1S being 4-5 spades, and X denying spades.

 

This is slightly worse because you'd like to bid 1D (1H) X p 1S with 3, and 2S with 4, but it's not a huge deal.

[straube]

Unfortunately, we usually are playing GCC. Thanks for the feedback.

Here's a scheme that could work:

 

1D - (1H):

 

X: Denying S, could be GF bal hand / forcing with a minor

1S: 4-5 spades, forcing

1N: Natural

2m: NF

2H: 6+S, game interest

2S: 6+ S, NF

2N: Natural invite

3C: Both Minors

3N: TP

 

One possibility is to replace 2N+ with Rubensohl-like semantics.

 

It would work similarly over 1D - (1S) as well:

 

X: 4-5 hearts

1N: Natural

2x: NF

2S: 6+ H, GI (or 5H and a minor)

2N: Natural invite

3C: Minors

3N: TP

[straube]

For those who play that dbl denies four spades, what does a 1S rebid by opener show?

 

Should dbl deny five spades but not deny four?

The trouble is that after suit interference, we're already out of system. Say it goes 1D (1H) 1S

and opener has xxx xx KQxx AKxx, he may judge to raise spades here. He may rebid 1N with

Ax xxxx AKx Jxxx. I mean, what else?

 

So we don't really have the tools we might otherwise have for 1D-1S, 1N. The 2H cue (unless otherwise defined) serves as a forcing bid while other bids are natural.

 

It seems like responder will frequently have a difficult time describing his hand if he's (for example) 2-suited with spades and a minor. It's hard for him to bid 1S with both Kxxx x xx Axxxxx as well as KQxx xx Ax AKxxxx. With the former, he'll want to bid 1S and then 2C (if possible). With the latter, he'll want to bid 2C and then 2S.

 

I would rather lose out on the NFBs and place them into the double hand. Some of them will be pleased to hear partner rebid 1N anyway. Something like Kx xxx xxx AQJxx.

 

I'm still wondering what 1D (1H) dbl (P) 1S ought to show. Maybe just natural with no heart stopper.

 

Jlall have any ideas?

Here's how Ambra (by Garozzo and others) handles the problem -- some responses switched:

 

1D - (1H)

 

X: 8-10 bal or 11+ bal

1♠: 4+♠

1N: Transfer to ♣

2C: Transfer to ♦ either TP or GF

2D: Constructive, NF

2H: 5+ ♠, 5+ ♣, forcing one round

2S: 6+ ♠

2N: 6+ ♣, GI

 

Over:

 

1D - (1S)

 

X: 4+ H, or GF bal

1N: Bal hand, NF

2C: Transfer to ♦ either TP or GF

2D: Transfer to ♥

2H: 5+ ♦s, constructive

2S: 5+H, 5+ C, F1

2N: 6+ ♣, GI

I'm first off wondering if their 1D is natural or not. It looks like it's made for a natural 1D.

I also wonder if it's GCC legal. Can the 2-level bids be transfers? I'm thinking yes, but I'm not sure. I know Bergen uses Switch and Rubin's transfer advances seem to be legal. But 1D (1H) 1S apparently has to be natural because it's at the 1-level? Is this right?

I don't think non-GF artificial bids are GCC after a natural overcall, i.e. 1X-(1Y). The short version is non-jump new suit bids basically have to be natural.

 

The long version... Transfers by advancer as specifically allowed, but not by responder after interference in general. Doubles are special in this regard, in that both 1) you can always use double for anything, and 2) if they double, you can play anything you want (like transfers). Jumps and 2-3NT bids are also allowed as raises (fitted or otherwise) or artificial GFs. I suppose you can still play 1H-(1S)-1N as forcing on a wide range of hands if you really wanted. 1N overcalls also allow any defense, subject to the "no woolsey" rule about known suits for 2D+.

[mycroft]

2) if they double *artifically*, you can play anything you want on the GCC. If 1D-X means "I have diamonds and want to defend" you're still on natural turf. Anybody play penalty doubles here?

[straube]

So we're thinking of using 1D (1H) 1N as something other than natural.

 

GCC legal? Sensical?

 

For instance, it could be a forcing or semiforcing NT suggesting diamonds or minors.

 

Is it very important to keep 1N natural there? We're not getting to game, right?

 

I keep thinking that lots of folks play 1D artificial and what are their methods?
