Two S9's in the same deck?
Anyway, it looks like declarer has 5 tricks in the majors. If declarer has
DK also, the contract is unbeatable unless I smoothly duck CQ and find
declarer with 3442 shape (and that he tries to finesse club again). On the
other hand, if the declarer knows we are good defenders, then he may suspect
that I have CQ, because it would be technically wrong for partner to not
cover CJ if he had that card. So, in an expert field, I'd rather take CQ

S J98x

D KXX
C XXX
And I was sitting West, ducking CQ;
CJ* CX CX CX
CX CK* CX CX
HX HK* HX HX
HX ?? DX DX
However, on the last round of hearts, East discarded his last club.
Game over.

So the conclusion is:
If you are playing in an expert field, you should take CQ.
If you are playing in average field but you are an expert pair, you should
duck CQ.
If you are playing in average field and you are not an expert pair, you
should take CQ. :-)))
It doesn't really cost anything for your partner to discard a diamond on 4th
heart.
