How to play flush draws.

[zkzkz]

In NL on the button with everyone else folded against an opponent I expect will fold to any bet after the scare card comes (if it comes).

Naively the flush draw needs only about 2:1 pot odds to make calling ok. But I find whenever the turn comes down offsuit my opponent figures out that his first bet was wimpy and puts down one I can't call for the river.

So given that you won't always get to see the river, what kind of pot odds would you want to see before calling a bet on a flush draw (if you don't expect to be able to get any more money in the pot if you hit)?

Should I just assume I won't see the river and play it as a 4:1 draw? Somewhere in-between?
