At the tables I seem to play at it appears that villian has a set with top kicker. Ace eight would be a logical starting had here. You called the turn after the board paired. What were you looking to pick up on the river? Maybe a re-raise of about half the pot would have defined your hand on the turn. I don't think that this guy was playing 8 4 but I guess you never know. His bet on the river looks like he doesn't want a call. I think that if i get to this river I call his all in bet. If he has the boat i pay him off.

I would bet the pot on the flop. On the turn, a re-raise might be a good way to get info, but it would pot-commit you probably.
I could see a set of sixes being played like this, only hand I would put villain on that beats you. Maybe he limped 8Ts, 86s??? I wouldn't think so. He also could have a whiffed flush draw, a massive overbet on the river usually reeks of that.
I hate these situations. I wouldn't be able to lay this down, I'm just not good enough.

This is a very easy call.
