What's the recommended defense to this anyway? I would think:

Double = takeout of diamonds
2♦ = majors

else natural.

We treat the 2C opening similar as
a 2D multi opener, and play the same
defence.

With kind regards

A resonable pd had known that 2 Club contains the weak two in about 90 % of all cases, so with a strong take out, he had act early.
So I give him 8-14 HCPs which makes 3 NT no nice goal.

I bid 3 HEart, this is just a little bid out of the LAW but many good things can happen. Besides some really ugly ones.

In the given situation, I doubt that there
was an agreed defence, and the guy sitting
direct behind the 2C opener passed, which
was the safe thing to do, absent an agreed
defence, because he was sure to get
another chance.
So just because he passed the first time, does
not mean he has limited itself.

What do we know.....?

Partner didn't overcall 2C (although it isn't clear what a 2D o/c could be, I would had take it as a take out double).
Partner didn't Double 2C. We also know (, at least after 3D we are 100% positive) partner didn't have any shape problems whatsoever that could prevent him from Double (or o/c 2D for that matter).

So, I gather partner is just trying to compete with second round double.

With this assumption, I Pass.
Double doesn't strike me clearly as penalty and even if it would, I am far from counting 5 tricks on defense.
3H is also possible, but I fear this can be too high and I absolutely dislike the fact of 50% of my hand being in Diams. (which also recomends we defend, right?).

Agree with Roland, although I've only played against this doo-dad once (an Iceland pair played it).

Is this multi 2♣ is rising in popularity? How long has it been around?

Has been around for ages in the Netherlands. And it is VERY popular there, if you play a tournaments or strong bridge clubs you'll run into it on a daily basis. There has even been an article in the member's monthly about "protecting the strong hand against interference" in this way.

I play it with anyone who wants to, here in Germany they are not really into such a thing even though it does NOT disturb the 2♣ opening structure much.

Defending against it you basically ignore the strong option. Apparently I am not playing my normal agreements against this opening bid because partner's Dbl would be penalty (he was trapping the round before).

The hand he is showing now would be Dbl then Pass in my system, using this defense I now pass.

Assuming opponents make the same mistake when partner Dbls directly and bid 2♦ then 3♦, the auction will go:

2♣ X 2♦ 2♥
P P 3♦ X

Thanks!
