Looks I have to study compound squeezes again, thanks for the explanation Frances.

So basically this squeeze worked when RHO help the KH, is that better then 50% ?.

With the diamond lead, you should probably finesse unless East shows out on the third diamond. If East shows out, he is more likely to have the HK than West, and the double squeeze would be favored over the hook. This loses if West had the HK and East can guard sp+d. But you are still OK if West has SQJ.

Squeeze will still win if diamonds are 5-3 ( likely from the lead) and you will of course ruff one D to isolate a D guard with west. If 9 or 10 does not drop from East, then you have to decide which option to go for, but I think its very close decision, and I certainly dont favor Heart finesse to be a lot superior then double S.

By the way, against average BBO field defenders misdiscarding on trumps is likely. Not likely to work against strong opponents, byt maybe something to have in mind.

I guess my point is that all declarers went down, but not because they took H hook or East kept D nine, ( almost all East threw diamonds early), they simply played the hand wrong.

This is not exactly true, yes the double squeeze will work if west has 5 diamonds and east has the K of heart, but what if west got the K of heart ? then you would want a♦♥ simple squeeze on west, but you wont make it cause you went for the double squeeze not the simple squeeze and played the A♥ earlier.
Anyway my point is you are still playing for not better then 50% (here u play on K♥ on the right) so, the heart finnese isnt a bad line.

Yes, I agree, but the decision is very close. I dont know if anybody can work out the actual percentages which layout is more likely. With QJ10xx♦ and K♥ and K♣, West will have a legitimate 1♦ overcall over 1club, so that is maybe one inference. He already showed 6 points, so probably placing the other king in East is a slightly better percentage play, also if you can figure out that East has 4 hearts, he is a 4:3 favorite to hold K♥.

Another option is if you have high enough heart in hand for threat, like 10 or 9, to place Queen of hearts on the table early and test West. If he does not cover, and plays in tempo, win the ace, ruff diamond, and play for the double S. Just a thought;).

I think as a rule of thumb, double squeeze is higher percentage than a simple finesse. (Whereas simple squeezes are worse, without additional clues.)
Here if LHO has long diamonds, then RHO has more vacant places for the ♥K, and thus the squeeze is notably better than the finsse.

FrancesHinden's analysis is dead on from my POV. Nice work!
