This was in a supervised deal and play session, but let's assume IMPs - low spots are approximate.

---

You get the lead of the T♥. East plays the 5♥. Plan the play.

When you tackle hearts:

Spoiler

When you lead a second heart, East shows out, discarding the 8♦, standard carding, usually attitude in this situation. If you led low to dummy, West ducked.

When you tackle clubs:

Spoiler

East has 4 (QT9x) and West has 2 (Jx)

When you tackle spades:

Spoiler

The spade finesse works.

When you tackle diamonds:

Spoiler

The K♦ is with East.

Did you manage to make it (assuming no brilliancies by the defenders)?

this is going to seem like a book sigh.
trick one play small from dummy and win the Q. I pretty much need 3 heart tricks to have a chance and playing LHO for the heart K OR RHO for a singleton K OR the suit breaking 33 is best accomplished by playing low.
trick 2 small heart toward the J is a reasonable continuation since any squeeze that might develop probably requires us to rectify the count.
there are all sort of continuations depending on what happened at trick 2 soooooooooooooo I cheated and looked to see what the spoiler said about hearts I was quite surprised the jack held the trick.
trick 3 spade toward the Q. Its 5050 and since LHO has no clue how many spades I own (no stayman) they are much less likely to return the suit. If the spade finesse loses we are reduced to finding clubs 33 and the dia K with lho sooooooooooooooooooooooo I cheated again to see if the spade finesse worked and hmmm suddenly our very weak looking contract is picking up steam. I now need 1 more trick and it is either a 33 club break the dia K with lho OR an endplay of rho holding (hopefully only 4-5) clubs and 3 spades to the K and the dia K.
trick 4 low club hopefully ducking it into RHO (much less complication that way since they cannot return a dia w/o giving me my 9th trick) and rho will correctly assume we do Not have the club J and therefore a club return is safe.
trick 5 win the club ACE (pretty much any other return other than a club and we are reduced to needing clubs 33)
trick 6 lead a dia toward the Queen but intending to duck if lho produces the T or J (there is still that 25% chance lho held the JT of diamonds and rho can still be endplayed in clubs.
trick 7 if the dia Q won we have our 9th trick and can hope for 33 clubs for our 10th. If the dia Q LOST we are reduced to needing 33 clubs. If we ducked the dia (because to the J or T being played we now have to assume 33 clubs OR our last ditch effort rho with 4 clubs 3 spade to the K and the dia K. Win any return go to the club K (if necessary and discover the 42 split) lead a spade to the ace and exit with the club and hope the endplay works. I would NOT cash the heart ace since that would increase the odds of rho ditching the spade K.

This is not a guaranteed LOP but it gives us a pretty reasonable chance of scoring up 9 tricks whenever they are available. How did I do?

Spoiler

You had to try the endplay without leading to the queen at trick 6 - I don't think LHO is going up with the J from Jx. I was RHO - yes I could have ditched the K♠ but I wasn't going to find that not knowing where the J♠ was - well if you gave me a second chance by cashing A♥ maybe.

Just goes to show that the bridge gods put the backs on the cards to make sure we can never beat this game only play it (sigh).
