What do you think is expert standard for Double in the following auction? If it is different, what do you play it as?

2♣-(Pass)-2♦-(2♠)
 X
♣ Veni, vidi, proficisci ♣

Surely Double here is penalty, presuming 2♣ is strong?

Won't presume to know what "standard" is. Pass=takeout, double=desire to defend 2S is our choice. 2NT? Heck, maybe a 2NT rebid.

As default, double is to defend in gameforcing auctions. Pass acts as neutral or takeout. Most serious partnerships have discussed this situation and many seems to make other agreements.

Generic forcing pass agreement - the X is for penalty.
We have changed this to T/O.

Which followes our general guidline, "all" low level doubles are for T/O.

Pass is forcing ( hence T/O ).
X = penalty.

Depends on the meaning of 2♦, but I'd take it as penalty.

I think it doesn't matter on the meaning of 2♦ -- whether it is simply waiting and possibly a 2nd negative follow-up or whether you play 2♥! as an immediate negative with 2♦ as waiting but positive.

Okay, so I guess pretty much nobody here plays it as 22-24 balanced then.

The following different sequence ( an immediate Overcall ) shows Opener with a 22-24 balanced ( I believe in Bridge World Standard ):

2C - ( 2D/2H/2S ) - pass! - ( p )
X = 22-24 balanced

where Responder's pass! was forcing ( whereas if Responder had Doubled, it would have been his weakest action -- immediate "2nd negative" . )

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Edit... I just clicked on the website in rbouskila's post for the Bridge World:

http://www.bridgewor...=bwsall.html#VB

and it shows that Free is right !!! Opener's X would depend on the meaning of 2♦ in your original sequence ( Overcall AFTER Responder's bid ):

2♣-(Pass)-2♦!-(2♠)
X = ??
If 2D were waiting but positive, then Opener's X = ?? undefined by Bridge World...

Bridge World only shows this sequence after Responder's immediate negative ( 2H! ) :

2♣-(Pass)-2♥!-(2♠)
X = PENALTY, whereas pass would be forcing.

- - - - - - - - - - - - - - - - - - - - - - - - - - - -
Conclusion: I have no (reference) answer for your sequence.
Something to be discussed with partner.

Edit 2: In my previous post I just "assumed" Opener's X was penalty for the 2D! ( waiting, but positive ) case also.
