Lead: ♥3

Assuming you pull 3 rounds of trumps,

T1: ♥3, 9, 4, 5
T2: ♥T, 7, Q, 2
T3: ♥8, 6, T, ♦3

Opponents playing UDCA. With 4-4 in minors they open 1♦. 15-17 NT, Normal negative doubles to show 4♠.

Assume LHO is 3334 (also works if he's 3325) with a spade honor (if ♠KQ are offside we can't ever make) and play a trump now.

If LHO pitches a spade, that's our 8th trick.

If LHO pitches a diamond, let's pitch a diamond from dummy and play a club now. If they clear clubs, it's the end of the hand, we have a marked endplay on RHO. They do best to win 2 rounds of clubs ending in the west hand and play a diamond through, but we can just win in hand and play a diamond back. If RHO plays the 3rd round of clubs now, we ruff and exit a diamond, endplaying RHO. If he chooses to cash his diamond, he squeezes his partner on that trick. (If it turns out LHO was 3325, RHO will be forced to squeeze his partner with the 13th diamond or break spades for us).

If LHO pitches a club, we can pitch a diamond from dummy and play a club. They cannot cash their clubs without setting up our 8th trick. They are free to cash 2 diamonds and 2 clubs, but now they have to either break spades for me or set up my 8th trick in clubs.
(If it turns out LHO was 3325, the same squeeze position results as in the second case where LHO will get squeezed in the black suits).

Edit: Actually I think I overthought this one, immediate club seems to always make as long as I play my trump before clearing diamonds.

Or use trumps to ruff out all the ♣ and tuck them in with a ♦. When you a ♣ after trumps, defense has to play a third ♣. Now ♦Q from hand. If they win, they are forced to return a ♦. Win in dummy ruff last ♣, give them a ♦ and they have to play ♠. If they duck the ♦, you play a second ♦ making sure you don't put up dummy's K, as now LHO can win the third ♦ and get out a ♣ forcing you to play ♠ yourself. When you play low, if LHO wins he is forced to play a ♣ which you ruff, play the last ♦ and force a ♠ play. The whole hand was:

If RHO discards a ♠ you have to throw them in with the third ♠ after eliminating ♣ and guess ♦, which is probably even tougher.

I was LHO. When 2♥ came back to me, I didn't want to sell out, so I doubled. My failure to double first, failure to bid NT, failure to bid 2♦ or failure to bid 2nt when balancing to compete in minors should make my distribution clear I thought. I was happy when I caught partner with nothing in ♥. I thought partner would bid 2♠ with that hand which is fairly easy to play for -1. Unless it's doubled, which is really tough for the overcaller to do looking at so much in ♥, it should be a decent spot I thought. All I remember about the hand is that declarer didn't play a ♣ or a trump after pulling 3 rounds. How we conceded an overtrick thereafter is something I can't reconstruct

In our section of 13 tables, only 3 -110's and our -570. but in the 3 combined sections quite a few -110s and even -140s, when even 110 needed non-trivial play.
