Assuming that trumps behave, you have 1 spade loser and 2 further diamond losers in your hand.  North has already shown all of his points for a weak bid by playing ♦ AK and presumably holding a spade honour.  The club finesse is doomed!  

It seems obvious to ruff one of those diamonds on table.   It is tempting to try and ruff the second diamond loser with ♥9 but how do you return to your hand safely to draw the remanding trumps?

The better plan is to execute a simple squeeze on South who must have to hold on to ♣Q as well as ♦Q.

Having ruffed one diamond in dummy, lead a spade and duck to "rectify the count".  You have now lost your 3 tricks.  When North returns a spade (say), take ♠A and lead all your trumps.  South will be down to just 3 cards so can't keep all his key cards!

Note that North could have defeated the contract by not starting off by cashing ♦A - but I'll leave you to work that one out!
