fd & oesd on turn?

What do you think he may have that beats you with which he hasn't yet bet or raised? Pretty much all his made hands need protection vs a flush draw or a (better) straight and if he has a really strong hand he still needs to get the stacks in so why would he check the turn and take the chance that you check behind?

I'll grant you that he may slow play a straight. If you are really worried about being check raised, just take the passive line and check behind. Otherwise there are quite a few made hands in his range that would fold to a barrel here I think, and if called you have tons of outs.

edit: I think this is one of these hands where the exercise of putting opp on a proper range street by street is very interesting and beneficial. Try it.
