Flush draws

[Yossarian]

Just want some advice about flush draws.

If I'm on the button with a good flush draw, against 4 or so opponents, I'll try and get the flop capped.

My main question is what to do on the turn if you miss the flush and it gets checked to you. Is it usually best to bet even if you expect to be raised? Or is it better to see the river for free?

I imagine theres not a lot in it but interested to know.

Thanks.
