NL200 6max - Delayed river bluff can work?

[MaxCaliber]

In this hand I was thinking about a bluff on the river representing a flush. I have called the flop, which points in this direction and he may see my turn check as a check-raise attempt. Do you think I can bluff on the river and if yes with how much? Around 40$?

Button is a semi-aggresive, good player who likes to cbet. I think I am percieved as a normal guy.
