I...

ugh, this is such a cruddy spot. we need villain not to have Ax, 6x, or a set about 33% of the time here for this to be a +EV call, I mean he could have 99+ here sometimes but probably not often enough... I think I sigh fold here.

I can't see how we can be good...no idea what kind of hand he could turn into a bluff on this river because if he has 77 and thought he was good on the flop he can't possibly think he's good anymore...

Fold. You're not going to be good often enough to make calling profitable.

I'd bet at least a little bigger on the turn (~$3.75) just so I can shove the river for slightly less than pot.

yea u gotta fold in a spot like that
