In NoTrumps count your winners - 1 in spades 2 in hearts 2 in diamonds and 2 in clubs - you are 1 trick short at the moment, hearts looks like the best suit to develop another winner
A spade lead - holdup for 2 rounds until forced to take it, play 8H and keep playing hearts to get the AH out. Discard low clubs on the spade return, win the club return with KC and make a diamond finesse hoping West has KD, play AD and QD, play KH and return to Dummy with AC, play your last heart trick and then lose the 10D.Hold up playing your AS on the opening lead to guard against a 7-0 or 6-1 or 5-2 spade split which could help you out if the one who has the long spade suit doesn't have the AH. You can't do anything if the opponent who holds the long spade suit also has the AH. In this case its a nice 3-4 spade suit but a hold up blocks communication between defenders. In this case the holdup does not help but it does not harm its a safety play
Makes 9 tricks, now you ask, should you have accepted partners invite to 3NT????
