Playing teams, red vs white you receive:

♠AJ
♥AQ4
♦AJT987xx
♣---

Your RHO passes as dealer and you...

Let's suppose you opened 2♣ (you can explain why it's not a good choice), LHO bids 5♣ (natural) and your partner bids 6♣. You have no agreement on this sequence with partner (who does? You can explain what you think it should be though) and RHO passes, what's your bid?

For another take on the same hand:

Spoiler

What about 1♦-5♣-X-Pass, what then?

[the hog]

I really cannot conceive of another opening apart from 1D. 2C is not an option for me - a long minor and a paucity of honours in the hand do not a 2C opening make.
This obviously affects your second question, but as you have started a guessing game, I guess to bid 6D.

Over 1D (5C) X I pass.

[whereagles]

People here hate 2♣ openers so they will be quick to criticize it and be happy to give it full blame.

But they are wrong.

The real question is what to do after the preempt and the choice of opening does very little, if anything, to solve it.

Anyway, regardless of opening 1♦ or 2♣, you're called to make a judgement bid afterwards. If it goes

2♣ 5♣ 6♣ ??

now 6♥ seems ok. Pard apparently has some sort of major 2-suiter. If diamonds were a possibility pard could have, perhaps, bid 5NT pick-a-slam. If, on the other hand, it goes

1♦ 5♣ dbl ??

I would probably bid a plain 5♦, maybe 6 if I feel lucky and/or need points.

[mtvesuvius]

I bid 6♦ in both cases. Not a huge fan of 2♣, but I can live with it.

[MrAce]

I would not have opened 2♣.

But now that i opened and pd bid 6♣, it seems like i have to find a way to get in pd's mind. Forcing pass was available but he did not, one can interprete this different ways. To me he should have a 2 suiter and i suspect he has majors. But i disagree with the remark "Who discusses this" I am pretty confident good pdships discussed what bid means what over a high level preempt after 2♣. Me and my pd did not discuss to be honest.

But whatever...i am bidding my 8 card suit now, how many more times am i supposed to conceale this suit ?

Hasn't LHO already done that?

Please tell me how opening 1♦ would have worked considerably better. I'm very curious.

I haven't seen partner's hand, but maybe a 1♦ opening would have saved us from having to play in 6♥ when we belong in 5♦.

I agree with this.

Bid 6♦. Partner has something like ♠ Kxxxx ♥ Kxxxx ♦ - ♣ Axx
Your 2♣ opener has worked quite well . Partner will probably play in 6♥ with chances in spite of likely bad breaks.

[jonottawa]

I like 2♣ and 6♦ now. 9.5 tricks with first round control in every suit is plenty for 2♣ imo.

LOL

and you are, of course, right?

I don't suppose you have a bidding book coming out anytime so that I can burn and replace all of my existing texts with your masterpiece?

I try to avoid opening 2c on hands where I am not afraid that the auction will fizzle. we are missing a suit, we have relatively short majors and we do not have an overwhelmingly large number of hcp. opening a natural ♦ gives my side at least one natural call to draw an inference from, rather than having p be completely in the dark.

[jjbrr]

I can't live with 2♣. Think 1♦ is totally normal.

Also the argument that it doesn't matter is just silly, unless you're telling me that there are no hands in which partner bids 6C after a 2C opener but not a 1D opener, which I don't believe.

And what if you've got the hand you're just as likely to hold like A, x, AKQJ10xxx, Kxx, I'm sure you'll enjoy playing 6♥ or 7♦.

I would open 1♦ rather than 2♣. There are hands where opps will bid 5♣ over 2♣ but do a bit less if 1♦ is opened.

I think 6♦ is my hand above, 6♣ is the hand in the original post IF you've opened 1♦.

Having opened 2♣, I don't think you can distinguish between the two hands.

[Phil]

I would open 1♦ but if you change the diamonds to a major its an easy 2♣ opener.

I really don't what partner is doing with 6♣. It seems 5N and then 6♥ would say "pick a major". I guess we can figure out in the post mortem if I'm supposed to bid 7♦ or not.

[JLOGIC]

Partner had 6C, 5N, pass then 5N, pass then 6C available. Who has any clue what the difference of all of them is? I'd guess partner has the majors.

Likewise over 1D 5C X p ? we have 5N and 6C available, what is the difference? Who knows, I wish 6C would be a really good 6D bid with 5N our bid when we have a slam bid with doubt about strain, but I would just bid 6D in real life.

[dake50]

Partner forcing slam with an aceless hand (well maybe CA).
He must be stuffed with the K's I need.
LHO long in clubs upping my chances to win anywhich finesse.
I'm in for 7D.

That was a political answer, right? I.e. the kind that leaves the question untouched

I was going to reply to this, but then I saw you're marked as a resident troll, so I will follow the canonical advise of not feeding the trolls.

Well, you know better than most of us not to overcook stuff in undiscussed situations. I would just say

5NT = pick-a-slam type, so majors with tolerance for diamonds.
6♣ = just majors I guess.

Other variants I would just take them as above and ask pard later what he had in mind.
