Well, the only question here, as others have said, seems to be the river.

Looking at the hand in a vacuum like this, I'd say I'd want to 3-bet the river if the A [img]/images/graemlins/club.gif[/img] is on the board, and just call if it's the 6 [img]/images/graemlins/club.gif[/img] on the board.

With the A [img]/images/graemlins/club.gif[/img] on the board, I just think a hand like A9 or even J9 is much more likely than a random flush. At that point, the only other hand I'd really think the opponent could have played that way is KQ [img]/images/graemlins/club.gif[/img], or maybe something wacky like KT [img]/images/graemlins/club.gif[/img].

If the A on the board is NOT a [img]/images/graemlins/club.gif[/img], then I just call.

I think calling or raising is the only decision, and honestly, when people make a move like that on the river when I'm 4-tabling, 9 times out of 10 I just call anyway, because the river check-raise is confusing and I'm saying WTF?
