I would cash the DA, cross to the HA and lead a diamond planning to duck. I think people will pop with KQ after that sequence of plays far more often they would split with KQ had you not cashed the ace.
Club, ace of spades and another spade, and take it from there. Choice comes when RHO wins the spade and returns a diamond. I think I'll play the Ace of diamonds at that point and continue a third spade.
