There might be a little bit of value on the first hand, but only if he'll call another bet with JT-KT. Other than that most of his range will have made some kind of two pair, or he was on a draw and managed not to hit - so he isn't calling anyway.

On the second hand I might bet on the river. It's unlikely that the A helped him, unless he's playing a hand like A6 or A7. But I think he might be raising you with those stats. More likely I think his hand is some kind of connector that hit a pair or a pair and a flush draw. I can see villan calling you with worse hands on this river, but not much worse.

If you make any decent bet, you are pretty much going all in. In that respect, I would be wary that villan must be REALLY bad to get all in with a hand that you have beat here.
