Initially you have 4 winners only 3 Aces and a King.

If the spades behave themselves you might be able to obtain 4 more there and if you can set up the Clubs you might obtain 3/4 more there.

Normally with 8 cards JXXX opposite AQXX you would play low to the Queen and then play the Ace praying for a doubleton King.

However here we have 9 cards and a shortage of entries to Dummy Therefore we are going to play that the suit breaks 2:2 with King onside or just maybe if the King is onside and suit breaks 3:1 then maybe the singleton is a singleton 10.

Enter dummy with the ♣Jack in order to finesse the ♠Jack.

Now play the  Jack which East covers. More importantly West follows with the 10.

You now draw the remaining trumps.

Now you have to deal with Clubs, You can either finesse the Club Jack or play for the clubs to be 3:3 and ruff the third club.

First let's come back to hand with the ♣Ace.

You decide to take the latter play.

No hurry trying the Clubs yet.

You want to play a Heart towards dummy- maybe West is a follower of 2nd hand plays low.

He isn't and takes his Ace straight away before getting of lead with his Diamond winner before exiting with a Club and the club suit does indeed break 3:3.

West takes his Ace and cashes his Diamond winner. Now you can claim the rest with more winners than cards left (1 Heart, 2 trumps and 2 Clubs)

You eventually made 5 trumps 2 clubs, 2 established Clubs, 1 Diamond  and 1 Club ruffed (in short hand).
