I'm guessing this is another one of those "it depends" questions, right? The more passive the player is postflop the more you would want to lay it down. Against an agressive player you would have had more of a chance for him to raise the flop with a club draw to get a free card also. So if an aggressive player raises he probably has a good chance of not having a flush. Also, I think the flush card has to be of some importance. A T,J, or Q of [img]/images/graemlins/club.gif[/img]s would be worse not only because of the straight possibilities but also more likely to have made 2 pair.
