Villain is a good regular. What do you think of this spot? I rangecheck on the flop and arrive with all my strong holdings on the turn. On the river my hand is probably just a bluffcatcher, since I dont think that villain would choose a pot sized bet with any weaker overpair. Do you think that this spot is over- or underbluffed? My general opinion is that paired runouts are underbluffed, however in this case villain could end up with the same conclusion. Call or fold?
