Partner leads ♦3 (3rd/5th) which could be Qxx, 10xx or even xxx.

Assume declarer is going to play a heart to the jack, what is the best defence?

I played ♦J at trick one, and declarer incorrectly won with the queen. He should have won with the ace, to give me the option of playing him for AKxx Qxx Axx Kxx
... 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

And you would then score 2♦, 1♥, 1♠, 1♣ and defeat him.

Oh, does that add up to five? Sorry

Why do you assume declarer will play a heart to the jack? If declarer has Axxx Qxx AQT Kxx then this is misère play and he needs to play on spades first, when there is no defence, as the winning opening lead (a heart or a club) has not been found. If your partner has the ten of diamonds, then any old defence will work (whenever it can be beaten), and I would just continue diamonds.
I prefer to give the lawmakers credit for stating things for a reason - barmar

If West tackles spade first,still the contract will be defeated if North switches to Club upon entry.

not entirely true. cashing all the diamonds and spades squeezes south. you can them throw him in on a club for a heart in the aj.

On reflection, I think that it's right to switch to a low club, catering for declarer's AKxx Qx AQx 8xxx. On the first round of hearts partner played ♥2, which ought to be suit-preference.

After QC lead by South 4 tricks are assured in his hand as long West hold CKxx,any entry in North's hand will defeat the contract.
