  Overtake with your ♣A.

As soon as you see the opening lead and dummy you should start figuring out just how you can defeat the contract.
Hopefully this plan came to your mind.

From his lead, you know partner also holds the ♣Q.
Overtake the ♣K.
Play your singleton 5.
When South starts on trumps, win the first one with your ♠A.
Put partner back on lead with a small ♣ to his known ♣Q.

If you have a partner who pays attention he will now play a for you to ruff. Two ♣s, the Ace of trumps, and a ruff makes down 1.
