$400NL. AA.... fold river?!?!?

im folding because from villians pov his overbet bluff would have to get you to fold the best hand more than 72% of the time to be profitable. Given that he knows his range looks polarised to us, making all our one pair hands the same, it seems unlikely that he can expect us to call less than 28% of the time, especially when perhaps 10% or more of our range is 7x.
