Here is a hand that i played recently, it was very frustrating since in the ending i should have known better, but ended up doing something stupid :(


You might not agree with 3, but the final contract is a good one.

I got the ace of spade lead, followed by the king. East followed with the 9 and 7 indicating an even number. Next west shifted to the jack of diamond. You don¨t want east on lead, so you try a small diamond from dummy. But east plays the queen and continues with the two of diamond. What is your plan now?

If the hearts are 2-1 even I might make 4 hearts on a good day, so you will find out that hearts are 3-0 when you play a high heart..

Ruff high (West showing out), trump to dummy (East showng out), ruff a spade to confirm that West is 6313, draw trumps. East is trump-squeezed on the penultimate trump.
... 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

If I understand you correctly, you will have reduced to the following just prior to playing the penultimate trump:

void
Hx
Kx
AK


void
Jx
void
J109x

RHO has A10 in diamonds and Qxxx in clubs (presumably....we are already home if he had xxxx in clubs)

So you play a trump and he pitches a club.

Whether you are in hand or in dummy at the end of this trick, you cannot both ruff out a club and get back to your hand.

Unblocking the clubs earlier changes the layout but not the result

You hold

void
Hx
Kx
void



void
Jx
void
J10

and RHO holds void void A10, Qx.

If you win the penultimate trump in dummy, he pitches a club. If you win it in hand, he pitches a diamond.

LHO's 10 of hearts prevents an entry-shifting lead of a heart from dummy, choosing to overtake in hand or duck depending on RHO's choice of discard.

Have I missed something?

Good point.

I think we can arrange an entry-shifting squeeze like this: ruff with the jack, heart to the king, spade ruff, heart finesse, AK, Q. Now we're in the same position as your second diagram, except that our hearts are Qx in dummy and Ax in hand.

Yes, after your suggested line I came down to:

-
Qx
Kx
AK


-
Ax
--
JT9x

Now I forgot to take for the AK in clubs prior to playing the heart queen. Very expensive and frustrating.

When you get confirmation that east has 4 clubs (when he shows out in spades), you could just claim.
