(3♠) X  (P)  4♣
(P)   4♦?

[aguahombre]

A good question to ask partner. My answer is "no", but I have been out of mainstream before.

[gwnn]

Not forcing. As a general rule it's never possible to force partner with a natural bid if he can still have 0 HCP.

Only exception that springs to mind is

2♣-2♦/2♥ some form of waiting bid that could have 0 HCP
2♠

which is played as forcing by almost everyone.

Not even something like

1♣-x-1♥-p
p-3♠

is forcing, even though it is obviously quite strong

[mohitz]

Non forcing but shows extras. Typically short clubs, 5+ diamonds and some hearts.

this seems contradictory. Having forced partner to do something intelligent at at least the 3NT level, I don't understand a non-forcing bid showing extras. But, just an observation.

[gwnn]

well, a double at the 3S level can be in practice (strictly as a function of HCP and cutting off the top of the range because those hands never come) 12-26.

12-16 is a minimum and will pass
17-20 is extras and can bid on but can't force to game so bids in a non-forcing way
21-26 can be treated as a GF and will bid something else.

These numbers are approximate, I am just using them as illustration that it is indeed possible for an extras call to be non-forcing, even at this level.

[ggwhiz]

Non-forcing but if you agree to play it in advance, it's "equal level conversion", at a high level in this case.

Basically, even after 1♠ - dble - pass - 2♣ then 2♦ by the doubler doesn't show extra values, just ♦ with a side order of ♥.

ie. (best case?) ♠xx ♥AQxx ♦AQJxxx ♣x can double a 1♠ opener without the risk of losing the ♥ suit by overcalling 2♦.

Especially effective at Matchpoints I think but pretty rare.

I don't see any contradiction in Mohitz' statement.

There is a difference between "shows extras" and "might have extras" with the ELC 4D call --either way, non-forcing ---extra king, or more, or not.

I have no idea why that would make no sense. Care to elaborate?

[jillybean]

So is partner expected to correct to ♦'s holding 3244 after;
(3♠) X (P) 4♣
(P)  4♥ ?

and

(3♥) X (P) (4♣)
(P)  4♥   must be a cue in support of ♣, 4♠ would be a choice of ♠/♦ game?


I see the need to play ELC at this level, is it also expert standard to play ELC
at the 2 and 3 level?

[aguahombre]

? entirely different auction
Different person bid 4C, etc.

oops corrected, I post too fast without thinking

[Codo]

To me 4 ♦ would be forcing.

Yes there are reasons why the approach that 4 ♦ should not be forcing is superior. But I would not rate them convincing enough to make an exception from the rule that double and an own suit is forcing.

This is BI not AE.

This rule is quite awful. I don't know how you come with that but I suspect there must be some loss in translation...
Doubling and bidding new suit is almost always natural, showing extras and not forcing.
For example:

1♠ dbl - pas - 2♣
pass 2♥

Is obviously not forcing and natural. Something like:
x
AKJxxx
AKx
Qxx

The OP's sequence is classically not forcing and showing very strong hand with diamonds. I can see a point for playing this as forcing or as some kind of ♥ + ♦ hand. No opinion what is better at 4 level but without some prior special agreement it's not forcing.

Where do you get that non-standard rule from?

Standard: Doubling then bidding your own suit shows extras but is not forcing.

Aside from being standard it has always served me well. I can pass when I'm weak and think we are high enough, I can raise or bid something else when I have a little strength and chances to make. What exactly is not to like?

[hanp]

I have honestly never heard of Codo's rule, and it would never have occured to me that this auction is forcing.

Me neither - unless partner had made a response that showed values.

[Codo]

Maybe I was on drugs when I wrote what I did.
Sorry.

Can someone answer these questions, please.
