Too bad you missed 3NT but the rest of the field probably did too. RHO leads the diamond 8, how do you play it? (It's matchpoints!)
A problem for the hungry

I hate this problem, whatever I try can be very wrong.
Take ♦A and play trumps, don't wanna take risks, lead is lieklly to happen everywhere.

I'd admittedly try to cash the clubs for the diamond pitch, hoping for the person with the doubleton club to have stiff Ace, stiff King, or AK tight in hearts, or a void.
No guts no glory, said the crazy man.

BTW, this wins when west has the AK8x of trump as well.... if I win the 1st ♦ and play trump, west wins, crosses in ♦s and the 3rd round of ♦s is fatal.

Play three rounds of clubs. I don't even need a stiff honor, I can do it most of time that RHO has a doubleton club, which seems very possible on the auction. If RHO ruffs low, play a spade to the board and the 4th round of clubs. If RHO again ruffs high, we are in good shape, and if RHO pitches, we still have chances, since we can crash their honors with Ax opp Kx. If RHO ruffs low with the other small spot, pitch, but for reasons below they can still hold you to 4.
If LHO has the doubleton club, I'm not any worse off, and still benefit from a stiff honor, although this is unlikely as it leaves RHO with a 1=3=6=3 and LHO with a 8=1=2=2.
I think I make anytime RHO's hearts are A, K, or Ax, Kx. Curiously, Axx / Kxx doesn't help me. I can pitch if RHO ruffs small a 2nd time, but LHO can also pitch his presumed diamond, and they can make their high trump separately.
This seems like a very good return on the moderate risk of catching either opponent with a stiff club.
Playing 3 clubs also thwarts a trump promotion when LHO has ♥AK8x.

It's quite hard to get a good estimate on the odds, as it depends a lot on what the opponents would bid 2D with (or pass 2H instead of bidding 2S). It seems reasonable to assume that the whole field is in 4H (top flight of 3, and really no other contract seems reasonable even though 3NT is superior given the 2D call). That means that we should go for it if the odds for the overtrick are larger than the odds for going down.
The shapes for east that seem most consistent with the auction and lead are (A) 3-3-6-1, (
A: 84*2*5 = 840
B: 126*5*5 = 3150
C: 84*5*10 = 4200
D: 126*4*10 = 5040
But only 80% of the C hands and 50% of the D hands give you an overtrick for a total of 3360+2520 = 5880 against the 3990 hands where you go down.
So my rough estimate (ignoring several more unlikely shapes) is that it is quite a bit better to go for the uptrick.
Of course, I didn't do this computation at the table but estimated that it was right to go for the overtrick. LHO was 4-1-6-2 with a small heart so it didn't matter.

Maybe these shapes are less likely but completely ignoring them seems wrong. They're still consistent with the bidding (LHO has 7 spades sometimes but doesn't bid, but in the context of the auction that makes sense), and not wildly outrageous, and your analysis would account for the likelihood of these shapes.

I ignored 2263 with RHO because I think that both lines would take the same amount of tricks in that case.
I didn't ignore 3-3-6-1, see (A).
I ignored 2-1-6-4 because I thought LHO would possibly/likely bid 2S with 7-3-2-1 shape. I agree that this isn't clear and there are other shapes that are possible. As I said, it is very hard to make an accurate estimate and my computation should not be seen as hard evidence that playing for the uptrick is better.

Call me an out-and-out rebel if you will, but Qxx x KJ109x xxxx looks like a 2D overcall to me....

On the contrary Justin, it is good for the forum morale to see that you also can make posts like that.

I guess ♦ A, ♥ Q,
Losing when LHO has 4 ♥ and 2 ♦
but gaining when LHO has a singleton ♦ and ♥ A K

Also, I am not so sure we can assume everyone is in 3N, I could imagine North rebidding 2N over 2♥, with South rasing happily. We need the traveler
