NL 300: Set meets riv bet with straight and flush possible

[CennyCripple]

First hand ever against Villain so no freakin read what so ever.

Do we call rivbet. I got really spuprised when he betted. I've shown strength enough to make a c/r turn or river with flush IMO. If he flopped a straight he should have played it more aggresivley.
But I only beat a bluff huh?
