Pretty common turn spot that I hate

[Wynton]

Considering villain raised pf, it's hard to see that he's going to have a 2 or 4 of diamonds in his hand. Possibly, he raised from MP with 55 or 77 (and one of them was a diamond). Seem more plausible that he raised with pocket Ts or Js (and therefore more likely that his flush is higher).

I am torn here about whether I could call a raise on the river, especially because it's such a bluff-inducing board. Is c/c the river (when diamond falls) so bad?
