Simple question, is it standard to play support doubles in an auction like 1♥(1♠) 2♦ (2♠), or do they only apply after one level response by partner?

Thanks in advance

No, that wouldn't be standard. The "standard" for support doubles is that they are off once the auction is above 2 or our suit.

I thought it was standard. I think it means "we have more than half the pack, and I have one card less in length than I normally would have to bid your suit". Pass or bid accordingly.

I have never seen this at the 4 level, but I'm sure at the 3 level it is not an uncommon agreement.

My expectation for X is extra values, no clear direction. If I had 3 diamonds, I would just raise diamonds.

If you play that 2♦ as not forcing (NFB) then yes, it shows extra values as a support double. I think it shows 2 cards in diamonds, because 3 diamonds is a raise to 3♦, as you are happy bidding at the 3 level on an 8 card fit when they have a higher ranking 8 card fit.

Perhaps we have the same idea after all. A support double shows 1 less than needed to support directly.

my agreements is that support doubles happen only when partner has bid a major that has promised 4 cards, but could have 5 (or more). Regarless of the level (but higher level shows extras)

So 1♣-(pass)-1♦-(1♠)-double its just take out. While 1♣-(pass)-1♠-(3♥)-double is support with a better than minimum opening hand.

Playing 2D as forcing or not forcing has nothing to do with it.

We do not have the same idea. My idea is that a support double always shows exactly 3. My idea is that It does not apply here. This is not "support" but rather cooperative.
