Luis, it's difficult to give a definite answer to your question of what requirements you need for the 2♠ bid. As you know, a 2♠ bid in this situation can be the lesser evil with a hand like
♠ KJTxx
♥ xxx
♦
♣ Kxxxx
Sure, you can build prototypes for the 2♠ bid, like the book examples on on stuff like AQJxxx xxx x Qxx, but in reality it's hard to say what type of hand 2♠ really shows, since it can vary a lot. The frontiers get better defined if you play weak jump, though.
As for whether if should be constructive or not, well, if you play 3rd suit forcing (e.g. 1♦-1♠-2♦-2♥* = art, forcing, inv+), then you can play 2♠ as not-so-constructive. Otherwise you may have a case for a constructive 2♠. I say "may" because it's not certain it should be so.
On the above hand, after 1D-1S-2D, I would pass 2D.
It will probably go down. However:
a. We are not yet doubled. If we are, I will perhaps trot out the spades, or maybe better redouble, which should show a hand that can't stand diamonds but isn't all that enamored with spades either. Also only modest hearts since with 5-4 surely I would have bid 2H or pulled to 2H. Pard can try clubs if he is really short in spades.
b. On some other day I might actually have a better hand. I would like partner to think more positively of my spades on those times when I do rebid spades.
So
1D-1S-2D-2S for me should be something like
KQxxxx
xx
x
Qxxx
You can't always get what you want, they tell me, but I would like to wait on something like this before rebidding 2S.
There is a neigboring thread discussing whether 1m-1M-2m-3M is forcing. In my style, no. Change the xx of hearts to Ax, and one of the spades spots to the ten, and it appears to me to be a 3S bid. With trash, pard can pass.
As noted, if you play that my KQxxxx, xx, x, Qxxx hand can be bid 1D-2S, then of course this changes things. Perhaps that's a good idea, I just have never done it.
