As much as I'd be thinking to fold the flop out of pure (and incorrect) nittishness thinking which says "fold to aggression until you have better reads", what is villain repping that beats you? QQ-KK is unlikely as villain would have raised you pre 9/10. AA is more likely than those as some regs like to get fancy with that from time to time, but still very unlikely. 5x and 8x are also unlikely, so flop must be a call. FD is more likely than a K on th turn as I don't see that there's much Kx he would have a) called pre with and b) raised on the flop so there's even a valid argument for calling the turn. This is a good example of "when a scare card is not a scare card".

Fold river.
