Flush Over Flush Draw

[Max Weinberg]

I'm sorry if this post has been answered in the past, but I searched through old posts and the archives and couldn't find much on it.

Here's the situation, 9 people limp to me with 2 [img]/images/graemlins/club.gif[/img] 3 [img]/images/graemlins/club.gif[/img] in the BB. The flop has two clubs on it. What are the odds of there being a higher flush draw out there?

I only ask this because I kept raising for value and want to know the EV implications of raising the worst possible flush draw for value.
