Your methods appear not to let you reach the best slam here, which is 6 Clubs. West leads the seven of spades, second and fourth, and East plays the three. Over to you.

Win in hand, cross over in clubs and take the diamond finesse (repeating it if it wins). If we have 3 diamond tricks I will duck a heart in case clubs don't break. If the diamond finesse loses, I will need something good to happen in clubs or spades, and then a squeeze to happen.

Clubs are 3-2 but the diamond finesse loses and there is no squeeze (any more).

I'll look later but heart to the 10 is better than ducking.

One can play to dummy, to T, say it lost and W played another spade, now casj AK of and when/if 3-3 cash 4th discarding a diamond from North. Now cash all 4 clubs and spade Q, E will be show up squeezed if he has 4 + K, W will be squeezed too if he has 4+ and K. Problem is if you play for this you will go down when K is on and W has the long spades.

Is this a TD issue Paul? Where W player did not have the K but slow discarded a diamond?

No, it is not a TD issue, but that did cross my mind. Declarer tested clubs with queen and ace, and then took the diamond finesse. I think the right line was is to test clubs then play a heart to the ten. It loses, and a spade comes back. Now you can try the spade-diamond squeeze (which works) and if the defender bares the king of diamonds in tempo, you take the diamond finesse. You are no worse off. If the defender bares the king of diamonds not in tempo, then you play for him to have been squeezed. If he bares the nine of diamonds not in tempo, then he gets fed to the pigs.

Yea but there are also a lot of people who says "you do it on your own risk when take an action depending on the opponents tempo"
Is that true?

Only partially. In sensitive situations such as three-card endings, one should be "particularly careful" when a variation may deceive. So, showing discomfort and breaking tempo before baring the nine of diamonds would normally be punished (sorry, rectified).

What makes you think this to be the right line? Because it would have worked?

When the diamond finesse Is wrong:

Your line (touching herats before diamonds) wins over the immediate diamond finesse when West has spade length and hearts are 3-3 (spade-diamond squeeze) or East has both heart honors.
Taking the loosing diamond finesse before touching hearts wins over your line when East does not have both heart honors, but either defender holds spade length together with 4 or more hearts or West has both heart honors with spade length. (spade-heart squeeze)

Comparing these 2 conditions is not simple
However, you can not squueze West between the diamond king and spade length without loosing when West holds the spade length and East the diamond king.
Neither defender has a discarding problem in this case and it is hard to see what the spade diamond squeeze gains over the straightforward diamond finesse.
Even without computing this in all detail and unless I overlooked something your line looks to me like the inferior one
