After opening strong 2♣, there are 3 ways to show 2♦ :
1- playing as waiting bid
2- playing as controls
3- playing as positive response
The worse way is as waiting bid, it is a wasteful bidding style, generally speaking, it promises 0-7 hcp in the past, now you see it is really tough to show the hand precisely.
Who play waiting bid? Who is willing to play waiting bid?
Last question first: I play waiting 2
♦. I have also played controls. I prefer waiting to controls. There seems to be considerable support for this preference, at least among these two choices, in the above responses. I allow that option 3, the 2
♦ as a positive response, may be better than either waiting or controls. I am cautious, however. For example, playing waiting you can have the following auction: 2
♣-2
♦-2
♥-3
♣-3
♦-3
♥.
At this point opener knows that responder has pretty much nothing in points but does have at least something of a heart fit. If this suffices, he can bid 4
♥. If not, he can pass. Playing 2
♦ as positive the auction, with this same weak hand, begins 2
♣-2
♥ and I am not sure how it goes from there. Not easily, I think.
With the current hand, if 2
♦ is positive I suppose ot begins 2
♣-2
♦, since surely an ace is enough for positive. Then 2
♥-4
♦. I like that, as I mentioned somewhere above. But still we have some stuff to sort out. Afaik, the 2
♦ does not promise an ace, it just promises values. Playing 2
♦ as waiting the auction 2
♣-2
♦-2
♥-4
♦ presumably also promises some values beyond the stiff diamond and the four trump. So I am not sure it is all that much different.
After the splinter support of hearts we are going to 6
♥, we have to sort out 6 from 7, and it would be good to have tools, independent of what took place before the 4
♦ bid. My choice over 2
♥ was 3
♥. I admit that if we were playing 2
♦ as positive then 3
♥ would not have seemed right, but I think I should have bid 4
♦ anyway.
Examining the merits of 2
♦ positive is on my list of things to do, along with losing weight and learning how to use various features of my cell phone. It may well be worthwhile, I have not yet done it. So far, I am more inclined to work through with partner more details of the 2
♦ waiting approach.
