4 to a flush, bad call?

[jujubeast6000]

I figured he didn't have the flush. And it was a callable bet. But question is, should I have bet it out first? Or maybe raised? Should I have folded?

Played it fine.

if you'd come out betting or raising, and had gotten reraised, then what do you do?

with all those clubs (and me not having a single one), i wouldn't have played any harder.
