Is this raise too thin, especially given the board paired? I figure I'm probably over-repping my hand here but I'm trying to focus on getting the maximum value out of my hands and I just don't think villain is gonna fold any Jx hand here on the river.

First of all, how much Jx does he have compared to stuff that beats us?

Second, I think this guy will find a fold pretty often with KJ and worse, unless you've been winning a few pots more than average at river without showdown. I want to see this guy call top pair to river raises before I'll start combo counting. I'm calling this river bet.

as played,call river.
i would raise/fold to shove turn

I feel like calling down and then raising river looks stronger than just raising flop. So if you don't think he's folding Jx here then he's really prob not folding flop?

I would raise flop. As played, I think it's a bit over-repping, I don't mind a smaller raise I guess. I would just call though 95% of the time.
