Anyone who can click on GIB in your diagram can answer this question even if they are blind and cant find without GIB. I really didnt understand the purpose of a double dummy trick 2 move question.

"Well to be perfectly honest, in my humble opinion, of course without offending anyone who thinks differently from my point of view, but also by looking into this matter in a different perspective and without being condemning of one's view's and by trying to make it objectified, and by considering each and every one's valid opinion, I honestly believe that I completely forgot what I was going to say."

Clearly the post is merely that of an interesting hand rather than an actual challenge. Though I agree, it would have been nice to see it posed as a single-dummy problem.

So he has a choice between 5C and 5D, and I think that 5D really does show a 5-6 shape but perhaps it is forcing, or at least shows a much better hand? I'm curious what others think.
5C could be silly when partner has diamonds, 5D could be silly when partner has clubs or equal length. Hard to say which is more likely. However, if the opponents bid again you'd sure prefer to have bid 5D.
I don't know if we want to publically discuss all of yesterday's cardplay errors, somehow those seem more painful than the misbids. On the other hand, it is possible that we would learn something.

I certainly wouldn't mind if someone could give me an argument on a single dummy basis that a club continuation is correct on this hand.

From the lead you know that Andy has 3 or 4 diamonds, so declarer is 6-4 in spades and diamonds, or perhaps 6-5. Given his play declarer probably doesn't have a void in hearts, so from Andy's count card in clubs you know that he has a singleton club (he can't have 3). So declarer's shape is either 6-1-5-1 or 6-2-4-1. 6-2-4-1 must be the most likely by far.
If so you know the hearts are running. You also know that declarer doesn't have the communication to ruff 2 diamonds in dummy if you continue with a club, and you can't prevent a single diamond ruff anyway.

I posted this because I thought it was an interesting problem.
I don't know how to tell hand viewer to hide the other hands. You can do this by clicking on North's hand.

may not have a spade trick). If they only have one leading
a spade is a sure way of making them lose it.
Declarer playing the club K off the board is almost assuredly
short in clubs and we know from the bidding they are short in
hearts (unless they are crazy). From there we can easly imagine
them having 4+ dia and the rest of their hand would not permit
them to run the dia to their dia suit because they know
they would lose the a and another trick even if we cant see it.
They cant know they are losing a heart so only a trump loser could
cause them a headache. Returning a low club will make transportation
almost impossible for them. They wont be able to ruff enough diamonds
and still be able to pull trumps. As long as we dont make it easy for
them the contract should fail on its own lack of ability.
