Well, if villain isn't an idiot, i reckon he pushes the turn with all the draws you think he will bluff the river with, so i don't think the river bet is a bluff very often at all.

That wasn't too clear, but basically all the hands you are ahead of on the turn (all draws) are the only things you're beating on the river. If villain was to bluff with these hands, he would probably just push the turn.

There may be the occasion he has A8, but it looks far more likely that he has boated up on the turn/ has a bigger overpair than you do
