Hamman's Rule?

White versus white, you hold the following as dealer
♠ 93
♥ 62
♦ KQT97
♣ 9653
You have a good partner, though you're certain not a well oiled partnership.
Expert opponents and team mates
Here's the auction
P - (1♠) - X - (3♠) - 3♠ is alerted as weak
P - (P) - X - (P)
I trust that no one will disagree with the first pass, nor the second.
For better or worse, I decided to pull the second double. (I've always played that the first double is for takeout, the second is convertable values, the third is blood)
What should 3NT show in this sequence?

2) On this auction I think partner would take 3NT by responder as a minimum hand with both minors.

I expect p to have a good hand for his second double.

Is pass really that clear over 3s with that hand? I would have bid something.
1) I would assume our first pass limits our hand to 10 hcp
2) I would assume our second pass limits our hand to less than a maximum given assumption number one?
3) I assume our second pass limits our hand to most 0-7 hcp hands or some /semi or balanced 8-10 hcp hands.
4) I consider this hand a one suited 8-10 hcp hand so bid something.

(2) I like a 4♦ bid in this sequence. Even if 3NT were "two places to play" it seems unlikely that clubs will play much better than diamonds even if partner is 3-4 in the minors. As for passing, there are probably around 18 total tricks on this hand. Opponents have nine spades if not ten, and we probably have nine diamonds. There's also no reason to think we have strength in spades, or that our trump suit is breaking in their hands (either of which could reduce the tricks). At IMPs, I'd definitely want to avoid the possibility of -530 (3♠X making) and am willing to pay the price of occasionally trading a +100 for a -100 (3♠X down one for 4♦X down 1). Most of the time I'd expect one of 3♠ and 4♦ to make. In fact five diamonds could well be making, but bidding it with the worst possible spade holding seems over-aggressive.

By the way, don't you think 5♦ is the right bid with the hand you gave? Can partner be any less than:
x
AQJx
10xxx
AKJx
about 75% to make given the bidding.

So the choice is between 4 and 5 Diamond and I will take the later bid.

You guys seem to assume responder has misbid.
Have our World Class opp really misbid?
If they have 10spades then they bid 4s at some point..not 3s.
I assume pard has 2 spades on this hand..not one.

3NT is surely to play...After (1S)-X-(3S), you dont stretch to bid 3NT on a reasonable 8-9 count do you?

But 4♦ seems par with your hand. There's a pretty high chance pard will have a doubleton spade, making 5♦ a long way. And if pard has a good hand, he can always mutter a prayer for you to have KJxxx of diamonds and take a shot at 5.

There are many hands with 10 spades between the opponents where it is right for them to bid only three spades.

3NT is to play, of course.

3NT will show that you are a mastermind because with xx he will pass it expecting to make and you will be down enough to make the bottom look like up.

Responder has a weak hand, opener doesnt have enough to bid 4♠ (either as an advance sac or to play).
Give partner a reasonable hand for his bidding so far, such as:
Ax AQxx Axx KQxx
and 5♦ should have some play, and this is about the worst hand I would expect. Better hands just make it easier. So I would just bid 5♦.
While many suggest that 3N is to play, this doesnt make a lot of sense. If you have a holding that is capable of bidding 3N at equal vul on this auction, you should be converting the 2nd X to penalty. While it makes sense that 3N should be "pick a minor" in this sequence, partner has already said they can tolerate whatever you bid. Since your hand has such a good diamond suit, it doesnt make a lot of sense to bid 3N to find a minor.
So many experts, not enough X cards.

Mike, the key here is that the higher level partner is going to force you to bid at, then the shorter he must get in the opponents suit OR the stronger his hand must get (and usually both).
In the cases where he has two spades, they will be Ax or KQ or at a minimum Kx. He cannot be expecting more than one spade loser given the auction.
RHO could well be holding Jxxxx xxx xxx xx and choose to bid only 3♠, the hand simply has too many losers and no stiffs/voids for a 4♠ bid.
So many experts, not enough X cards.
