NS Vul N dealer IMPs .Bidding was
N opens 2 (Multy weak M or strong any)-dbl by E(Values or Very good suit)-2by S( support)-3byW (Natural 1RF)
P (Confirms weak M almost certainly )-3(cue in spades support)-P-4(Cue in )
P-5-p-6 -p-p-p
So North has shown a weak 2 in Major.East has shown Good Diamond suit or Opening values or both.South has shown abilty to play at least upto 3 .West has club suit and at least opening values.
N lead 4 (std leads)
Dummy has singleton , 3 rags , 7 card Diamond suit headed by AKQ and Jx in
Declarer lets out a barely audible hmm before playing a card from Dummy.South wins Ace.
What should South return?

I don't know what you think we should infer from from declarer's "hmm". It might mean that 6 is a good contract, or that it's missing two aces, or that 6 is better, or that he doesn't know how to play the hand, or just that he thinks his partner should have bid differently. The last of these seems quite likely, in fact.

Anyway, I return a diamond.

Partner opened a vulnerable 2 spades in first position, if he has KJ K contract won't be beaten unless an unlikelly diamond ruff happens.

Heart only works (I think) when partner opened with 7 spades KJ10

Spade works antime he opened with the ace.

I think spade is much better.

Why can't partner have a singleton heart, making declarer 3=3=1=6? KJ109xx in spades is enough for a weak 2, partner doesn't need any other high cards.

That's not a weak 2 vulnerable versus not in first position for me. With that holding both diamond and heart works, so a diamond might be better.

is better than if declarer is 3307 (or Axxx??,Kxx,--,AKQ10xx).

Assuming declarer controls -- which is perhaps indicated by the 6 bid and possibly supported if the "hmm" expresses ironic surprise at dummy's diamond controls -- and assuming partner hasn't led a low heart from x4 or opened 1st seat vul with a 5-card suit,

If declarer has AKxxxxxx the only chance is Kxx,x,x,AKxxxxxx and a shift.
If declarer has AKQxxxx, a will work and a will be ok also vs. Kx(x),Kxx,(x),AKQxxxx (which helps explain the weak 2).
If declarer has AKxxxxx, a will work, a may be ok (if partner A), and a works if partner has 7 .
If declarer has AKQxxx, a will work, as previous, will work.

If declarer does not control then

If declarer has 7-8 clubs, the only chance is a .
If declarer has AKQxxx, a will work if partner is 7123, a if partner is 6313 or 7123 with A, a if partner is 7303 (maybe KJxxxxx, Kxx, --, xxx?)
If declarer has AKQxx a will work only if declarer bid surprisingly to ignore 3NT, a will be ok if partner isn't very light for the opening bid, a is good if declarer is Axx,x,J10xx,AKQxx which seems a very optimistic 6 bid.

There seem to be a lot of imponderables, such as explaining the opponents' bidding. makes the most sense to me, perhaps because I am not used to 7303 weak twos.

2 = Multi.
-X = Penalty.
2 = Like .
3 = Cue.
4 = Cue.
hm = Why didn't I bid 6N?
IMO = 10, = 6, = 5.
The 4 looks like a singleton.
I guess the layout is something like that on the left.
West can try the false-card of K.

Hmm Why didn't I at least bid 5NT to give partner a choice if he has the AH rather than the AD then six of clubs with second choice 6D is better than 6 NT.

My hand was AJ10xxx Kxx X xxx.My partner thought I had a singleton and tried to give me a ruff.When I suggested that hmm indicates 'missing 2 aces and he should have returned his angry retort included most of what gnasher has posted.He further added next time instead of paying to attention to trivial details like hmm I should concentrate on own cards and select proper opening leads eg K on this deal. :angry: On the other table North hand opened 2 spades E passed south after a crafty 2NT ( strong inquiry!) played in 4 spades and made.
hmm

Hm... xxx x Jxx AKQxxx
Hard to believe that declarer made only one grand-slam try with his useful ten-count :)
