The S hand is borderline for 3♦: the stiff ♠Q is probably not full value, but the internal texture of the (7) card suit argues for aggression. I wouldn't complain to partner if partner bid either 2 or 3♦, altho I personally think it is a 3♦ call: I would use LTC to break the tie.
After 2♦, responder has an easy 2♠, which is simply a game force, ostensibly based on ♠s. However, responder knows that there is no real likelihood of being raised here: certainly not beyond 3N. Opener might have to raise on, say AQx x AQxxxx Jxx: I think 3♠ here is best.
Anyway, that is an irrelevancy.
Should opener rebid his ♦s after 2♠?
IMO, no: he has shown 6+ in the suit already and someone has to bid notrump.
Give responder 4=5=2=2 with Kxxx KQxxx Ax xx and we are beyond 3N (I note that the form of scoring is not given: this issue is of far more importance at mps than at imps.
So:
1♦ 1♥
2♦ 2♠
2N ?
Now responder has a real problem: we are beginning to see the problems arising from bidding only 2♦ with a 5 loser hand!
It is easy to say that responder should upgrade the ♦A, but what if opener held xx xx KQJxxx AQx... how would the auction be different?
And 3♦ here sounds like 2♠ was an artificial gf based on primary ♦ support, for which Ax is a little light.
If responder did decide that the hand was worth one mild try: then he continues 3♦ and now wild horses should not keep S, who has been underbidding, from driving to slam.
But I can see a lot of players bidding a simple 3N, ending the auction.
If opener rebid 3♦, which I think is correct, then slam is pretty easy, even if the partnership has no way to stop in 4N.
1♦ 1♥
3♦ 4♦
4♥ 4♠
and several ways to go from here.
Given that this is the B/I section, I assume that most would treat 4N here as keycard (I don't... for me, 4N denies the ♣A but promises a hand too good to signoff in 5♦.. I would make this bid hoping to hear 5♣, but intending to bid 6♦ otherwise)
Responder should not take 4♥ as delayed ♥ preference: the 4♦ bid committed the partnership to ♦s or notrump.
If responder wanted to go slower, he could try 3♠ and then over 3N, either bid 4♦ or bid 4N... however, I think those choices would be errors.
3♠ then 4♦ suggests responder is bidding around the ♣ shortness, and he doesn't have the right ♣ length...
3♠ then 4N fails to give true value to the undisclosed ♦A: we know that partner's suit is now solid, but he doesn't, so he may be too pessimistic if he has stretched based on his suit (as he has). Furthermore, it devalues, for slam purposes, the internal strength of the ♥ suit.
So I think opener should rebid 3♦ and then N will make a strong slam try of 4♦, over which S, with all side suits controlled and the hard-working (opposite most slam-try responses) ♥A, will drive to slam.
