The problem is more complex at matchpoint play, but even then the prudent line begins by taking the diamond finesse, leading up to the King. Diamonds is the suit in which you have a sure loser, and playing diamonds first, at worst, might result in the opponents cashing up to 3 "quick" diamond tricks. But the club finesse for your ninth trick would remain available when you regain the lead.
If you start instead with the club finesse and it wins, it is true you will have have nine tricks, and can then safely try for 10 by crossing to hand in spades and leading a diamond toward dummy's king.
But if you start with a club finesse, and it fails, the opponents certainly will continue hearts, leaving you with at least 3 heart losers, a club and at least one diamond trick, regardless of whom has the diamond ace.
So in situations such as this one, to maximize your contract's chances:
If one of two finesses can produce the extra trick you need, the best play is to first try the suit where losing at least one trick appears certain. Hold the "A-Q" finesse in reserve!
