Bridge in Oz

Came across this deal playing with my phone today.

♣ A83

Declaring 7NT with no opposing bidding and the ♣5 led, you play small from dummy and the 8 wins. What's your plan to maximize your chances?

If you play off your top black cards first and spades don't break, you'll have to pitch a third red card prematurely. I think best to start with the spade Ace and then Q-A-K of hearts in case the Jack drops.

If not then play off the top clubs and spades. If RHO has the ♥J then you will get a 3rd diamond trick any time it is possible to do so, including with a double squeeze if LHO has the 4th spade.
