Best play for making 3NT

I don't remember the source of this hand. I had posted this on bridgebase forums a few years back.

Playing Rubber Bridge, you reach 3NT as South. West leads the HQ and you see:

Rubber
None 
 Dummy
♠ AJT9
♥ AK
♦ K32
♣ Q932

   


 You
♠ KQ8
♥ 432
♦ Q54
♣ AJ74

How will you play?

Solution [Added Dec 13th 2014]

You have 6 tricks in the majors and need three from the minors.

If clubs are 3-2 you can get 3 tricks from the clubs. But if they are 4-1 or 5-0, you can get 3 tricks if LHO holds the club length, by playing a club to the J (and later the CA and then club to 9).

The problem occurs when RHO holds the club length: you can only get two tricks from the clubs and would need a trick from diamonds.

You only have a single heart stopper left after the opening lead. If you go out once in clubs, a heart will come back and you cannot go out in diamonds now.

The solution to this is to play the CA, then play a club to the J from dummy!

If clubs are 3-2 or LHO has the length, you make 3 club tricks.

If RHO has the length, he cannot go up with the K (otherwise you have 3 club tricks). Once you win the J, you shift to diamonds for your ninth trick.

A 100% play.
