[Rockymv]

Villian is 57/16. His line screamed flush draw to me. Do you call the river?

Ehh, I hate these situations. Typically when an opponent minbets and then calls a very sizeable raise he either has a strong hand [ie. a set] or some sort of strong draw. Have you seen him do this before? Any read on what his minbet is? We dont beat much here, probably only a busted flush draw, and I dont know how often your opponent has that, I dont it is enough to make this profitable. I fold and take a note of this.
