Hi,

Partner opened 2♣ RHO X what do I do?

I passed then put opener into 4♠ but a needless RKB got us to 5♠.

We made but I hand no clue what to do.

What defensive schemas are people using over Xs and two level suit interventions?

What are the most commons response?

Many thanks.

I would have bid either 1♥ or 5NT I sometimes do better when I have a hand, but not always.

I think the most common structure is that pass is the way you show the kind of hand that would have made a positive response (whatever your partnership's definition of that is) without the interference. Bidding a suit shows a weak hand with that suit, while double and redouble show weak balanced hands.

So if you pass and then support partner, he would be justified in exploring for slam.

[Antrax]

Doubling 2♣ actually gives you more options.
The I/A solution after a suit bid is to play X as weak (either double negative or just 0-7 HCP), a suit bid the same as a positive response to 2♣ (so for us a good 5+ card suit) and pass as a not-negative hand without a good suit to show.
After a double, opener has to guess whether to pass for penalties or take the double out to their suit.
After a pass, opener can double to suggest penalty, or start bidding their suits normally.
After a positive response opener basically ignores the interference.

It's far from being a very good solution, but it's pretty easy to remember, and it happens quite rarely, especially if you don't open 2♣ on playing strength alone (if you do, it's more likely you'll have a long suit and the opponents will have one of their own).

I like this and it is a good link to send to new PD's but if she says what to do when 2♣ is doubled I can't find it.

1♥after 2 ♣ ...Great

Without interference:
2D = waiting, but positive ( at least an A or K or 2 Q )
2H! = bust

With: 2C - ( X ) - ??

pass = positive; would have bid 2D without interference .
any suit = natural and positive, EDIT: except this time, 2D and 2H are natural.
XX! = bust ( this is not standard; EDIT: may switch pass and XX meanings ).

I don't see what the problem is when RHO doubles. It takes no space, and doesn't prevent you from doing anything you would have done if RHO had passed.

So, all of your bids mean exactly the same thing. However, you have two additional calls - pass and redouble.

Redouble should be natural. It says you have clubs and that you may want to play it in 2♣xx.

Pass essentially says that you have nothing to say, but if partner wants to play it in 2♣xx, partner can redouble.

I don't think you ever want to play in 2♣x, since it is not game.

Actually I think XX as a bust is standard...

Hardly. And it makes no sense.

[helene_t]

Maybe I shouldn't suggest nonstandard stuff here but what about a general agreement about what to do when they double an artificial bid? They may also double stayman, fsf etc. Pass=nothing to say, xx=to play is easy to remember .
But of course it may depend what responses you normally play after 2c. If you play 2h=bust you probably want to have a bust call here as well

[the hog]

If they x an artificial bid, xx should be a meta rule to play. Thos who have played relay systems will see the logic in this.

That works ok here, or in relay auctions I imagine, because you expect it to be your hand so, as ArtK78 says, if you want to play there at all you want to be redoubled.

In other situations that isn't the case. If it goes (1NT) 2♣(majors) dbl, and I have a weak hand with long clubs and no support for a major, I want to be able to pass to play.

[Phil]

I play x and XX as busts and I think that's fairly standard too, at least on the west coast. If doubled, pass is balanced (or default) and suit bids including 2!d are natural. I've never discussed 2N but logically that's the minors.

You could soup this up but it's a pretty rare auction and as long as you have a basic agreement you are fine. I do remember writing down -1600 once when partner and I weren't on the same page.

[mycroft]

Standard here, too, is XX=bust. That certainly leads to +760 on occasion, when the big hand decides "we don't have game, except possibly for this one; if it works, they're never interfering in our 2♣ auctions again."

But I can see switching the rule and making XX=to play. The issue with that is that +1160 isn't +1430, but it certainly is better than +660 - and opener has to guess without knowing anything about partner's hand except "I have clubs too, and a GF. Not able to tell you about support for your suit."
