My guess: After ruffing the 3rd ♦, cross to ♣A and run ♠T (LHO shows out). Finesse ♥Q (wins). Lead another ♠, covering RHO's card. Cash ♥A, ♣JA, Lead a card from dummy, couping RHO if he is 5233. If RHO covers ♠T, you might make an overtrick.

The logical goal is 4s here. (with no beat from opponent)
Cross ♣ (A or K) then run 10 K if fail then i try the finess H(j or Q). if fails both lose. if at least one works win. (if the first Finess works you may go from 4 S).
in ANY case if one finess works here you should go back on s from avoid the ruff.
But if the s is 4-1 you lose anyway one more s. in this case i cross the back with C and i play the As ,then onother s and so fur i had one more on my hand. Then i take the next trick (by ruff on D, by Qc or if East try H by finess try). This plan works
Anyway you can watch and the GIB. from your hand...

Ok this is my thinking line. On 5-0 s is no hope, on 3-2 is try win one finess. on 4-1? i dont really now if is the correct plan

(LHO shows out)

♠s were actually 4-1 with the K onside. So, ruff the 3rd ♦, cross to the A♣, lead the T♠, winning. Lead a second ♠, putting in the Q and LHO shows out. Now you can afford to lose a ♥, but you need to take one more shortening ruff in hand and get back with dummy on lead at trick 12.

So A♥ and a ♥, losing to LHO. Ruff (or overruff) the return and go back to dummy in ♣ to coup RHO. If LHO leads ♣ when in with the K♥, you will be glad that you played A♥ and another. If you use a ♣ to enter dummy and take the losing finesse in ♥s, LHO will return a ♣, and leave you short of an entry to be in dummy at trick 12 after taking the necessary shortening ruff.

I saw the line in the play, but rejected it for some odd reason as too speculative, fearing I was falling prey to FPS (fancy play syndrome). So did everyone else who even considered it, I guess.

What shape was RHO? Biggerclub's line is cunning but RHO can usually thwart it by discarding ♣s at every opportunity For example, If LHO has 5 ♦s, he can lead a 4th round Perhaps, the ♥ finesse is a better bet at single-dummy

[biggerclub]

Well it works here because ♦ are 4-4. And it works anytime RHO has at least 3 ♣ and at least 7 cards in the minors, to go with the four ♠ that I already know about. And if the K♥ is stiff.

But everyone, including me, took the finesse so maybe our collective instincts/analyses were correct.

When you ruff a ♥, a cruel RHO can discard a ♣

edit: just noticed west can exit a club, which would destroy the coup.
