  Play the 10, NOT another ♠.

You can see the ♠6, ♠5, ♠4, ♠3 and ♠2.
So the ♠7 is East's lowest ♠, he is doing his best to discourage you from leading the suit again.

South held up with ♠ A J x, hoping you would play the suit again and give him two tricks.

If you play the 10 East will win the A and return a ♠, allowing you to drive out South's ♠A while you still have the ♣A for an entry.
