K high river call

[Pog0]

conversely, do you think villain is making a profitable play if he's bluffing here (obviously not if K high is calling, but usually it isn't)?

His flop c/r can't be a free card raise because he's OOP but it could be an equity push with an OESD+FD.

With low aggression numbers, he's probably not c/r that protected flop without a pair. Maybe then he got scared on the turn and value bet the river.

I'm probably folding an ace here a lot of the time as well.
