The default rule in Acol is that a new suit at the 3 level is forcing. I can see no reason why this auction would be an exception unless playing some sort of GB2NT (which you would surely have mentioned). And in almost any system other than Acol this would barely be a question.

Yeah, we have talked about it but been too lazy to adopt it.

I am not sure if a gb2nt is practical in this auction, especially when you play weak nt. GB2NT could easily wrongside a 3nt contract. It is more useful in balancing seat, and when you have already found (or are likely to have) a major suit fit, or when notrumps has already been bid, or when the 2 was a raise rather than an overcall.

With the assumption that the 2C response is "SAYC" showing at least 11 (some might say 10), I would say that both 3D and pass by opener are forcing. The way people float in nowdays, giving up a cooperative penalty double of 2S to create a forcing bid seems wrong. By cooperative penalty, I mean responder defends 2S doubled unless he has a heart fit, is really short in spades, or has a ton of clubs.

As Zelandakh says, the default rule in Acol is (and has always been) that a new suit at the three level is forcing.

Furthermore, in modern Acol a new suit after a 2-over1 response (e.g. the uncontested auction 1H, 2C, 2D) is forcing. Bidding 3D a level higher in the disturbed auction shows extra and must be forcing - I would argue that it must be GF.

To me, if opener bids a new minor at the three level, it is forcing for one round at the very least, whatever system you are playing. Opener is unlimited, except where a partnership are using a strong club system.

Be advised that last statement is not universally true.

Agree. Opps have taken away your weak 2h reply (hugely passable in standard acol), but have given you the ability to pass.
So 3d is free bid of " new suit at the three level" which in my rudimentary days was forcing for at least a round.
And I am still in my rudimentary days (before you point that out.....)

Hi,

I dont have played Acol for a long time.

The question is, how do you discover a possible diamond fit?
What is the meaning of openers X?
What would be the meaning of X by responder?

I think those question are more relevant, than anything else.
If you have answered those (I would play both as T/O), but what
ever, than you can discuss, if a direct 3D or a delayed is stronger,
again, coming from a NFB background, for me the delayed would be
stronger.

And 2NT as good / bad is also helpful, opener could still have a
strong NT, but first things first, and this would be clarifying the
meaning of X.

With kind regards

Agree. I don't play Acol but would like to know the answer. New suit at the 3 level is forcing, but bids after opponents' bids are not necessarily. If double is "values" without much to say, perhaps a 3532 shape 15 count, and therefore quite passable, 3 is forcing. If double was takeout, then it could be the start of forcing auctions with X 3(say) 3 as forcing, and 3 rather than X is not forcing.

My choice is "values", so 3 is forcing, but I do not believe this is a universal opinion.

3 is forcing unless opening bid was systematically limited.

"Well to be perfectly honest, in my humble opinion, of course without offending anyone who thinks differently from my point of view, but also by looking into this matter in a different perspective and without being condemning of one's view's and by trying to make it objectified, and by considering each and every one's valid opinion, I honestly believe that I completely forgot what I was going to say."
