flopped flush, how is my play?

I lead the flop - no reason to believe anyone bets this scary board and you have to protect your hand: you don't want to see a heart turn or a paired turn. After the check you should c/r ...
Lead turn his bet on the flop could be a steal-/probe-bet and his turn bet is not for sure. C/r afterwards is good.
I lead river for more $$ if he has a hand (TP or better) he'll call more. If he has no hand he won't call your small bet anyway.
