  Play the ♣J.

You should not allow yourself to be misled by South winning the first trick with the ♠Q. East does not hold either the ♠A or the ♠J or he would have played it. South is just trying to be deceptive.

That means you need the next ♠ play to come from East, so you play your ♣J and let East win his ♣A. You can be sure East has the ♣A because South would have played the suit differently if he held the Ace.

East will win the ♣A and return his ♠ through South's ♠ A Q.
This allows you to set up your ♠ suit while you still have the ♣K for an entry.
