Scoring: IMP

2♦-ps-2N-ps
3♦-ps-??

2♦=weak 2
3♦=min,no short suit

i'm not bidding 3 no, they're leading through partner's hoped for spade stopper. If he has a good spade stop then his diamonds must be terrible! ♠QJx with ♦Axxxxx I guess could be described as a minimum but even with that hand 5♦ will be OK. As opposed to that we have Kx of spades or xx or diamonds with no ace (admittedly unlikely).
... and I can prove it with my usual, flawless logic.

I would try 3♥ to involve partner a bit more.

5♦; You have 11 tricks in 6♦, 3♥, & 2♣. Partner is a favorite to have only 2♠ as 2362 and 2263 combined should be more probable than 3262. Perhaps my view is colored by my expectation after 2NT that he has no outside K or A so I do not expect Jxx Qx JT9xxx Qx or similar.

Agree with pooltuna's reasoning that 5♦ is better, provided partner is guaranteed to have 6 diamonds. 3NT if not.

Partner denied a singleton so I am bidding 3NT and expecting spades 4-4. They can cash four spades and we get the rest. If we don't get the rest when spades are 4-4, then we were not going to make 5D either. Also, they might not lead spades.

Why do we expect spades to be 4-4?

I think we could tell that simply by looking at our own diamond holding!! :)

Maybe, but then again, they may be able to cash 3 spades first.

Why do we expect spades to be 4-4?

Wishful thinking?

I think this is the wrong way to approach the problem. If spades are 4-4, 5D will make whenever 3N does, for the same score at IMP's, so our concern really should be what happens when spades are not 4-4. Ok, if diamonds are 4-0, and partner has the club Q and the diamond Ace, we would have 9 tricks in NT and 5D will go down, however, this is too specific to worry about, imo.

If a spade is not led (against either contract), both 3N and 5D will again likely make, regardless of how spades break, so this isn't a consideration either.

However, 5D gains when partner holds two small spades, spades are not 4-4 and a spade IS led.

This leads me to choose 5D over 3N.

Obviously if partner has a doubleton spade we would all bid 5D (I hope!). The reason to think about playing 3N is the times that partner has three spades and you can lose the first 3 whereas you will make 3N usually.

Yeah, but a doubleton spade seems just so much more likely than three of them.

Agreed, not saying I would bid 3N, I just thought it was LOL that the discussion about bidding 3N vs 5D all assumed partner had a doubleton spade.

I think bidding 3S would be kind of sexy to deflect the spade lead against 5D though.

5♦. Although I like the idea of either 3♥ to involve partner a bit, or 3♠ to deflect a ♠ lead, I guess I'd probably just blast it at the table.

3♠ is natural here, isn't it? If partner raises and you go back to 5♦, everyone will know 3♠ was a psyche. And if he doesn't raise you don't mind a spade lead anyway.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn
