It was IMP.
Here is South's hand: ♠Qxx, ♥xx, ♦Qxxx, ♣QJ9x
Should South accept invitation (North bid 3♦) or not?
I would have bid 4♠ directly. Any cards from South would be helpful, except ♣Q, even ♥Qx(x) or ♥Jxx is useful. An average 7-8 hcp hand from South would be good for game.
I wouldn't bid game with this hand after a 3
♦ try.
When playing with less-experienced players (which I should do more often, but I don't really play at all anymore), I used to discuss these sorts of tries. Imo, to accept a help suit/long suit try, responder needs to do more than just look at his holding in the suit.
He needs to assess whether his raise was within the mid to upper part of the range for the raise. For example, with xxx xx KQxx xxxx, had I bid 2
♠ on the given auction, I would NOT accept a 3
♦ try. I have a sub-minimum raise and my superb help in diamonds shouldn't be enough. If it is, partner had a 4
♠ bid rather than a game try.
So in this case, the raise was in the minimum part of the spectrum. Pure 'walter the walrus' types will say, no doubt, that the range is maybe 5-9 and we have 7 and a doubleton heart so it's mid-range, but proper valuation suggests that this is what is known as a very soft 7 count. It lacks any Aces or Kings, and Q's and J's are over-valued in the 4321 count, especially in trump contracts.
If as opener all you need is a fitting minimum, just bid game. You gain when he has a fitting hand, minimum or otherwise, and often you find that a non-fitting 'good' raise makes up for the lack of fit and, as I pointed out in my first post on this thread, concealment of your hand-type will often make defence very difficult, thus allowing you to score up the game even when you 'should' go down.
