He could have some kind of a draw on the flop that he "gave up" with on the turn and wants to bluff with it again seeing you are checking and he probably thinks you have a weak hand. I think we can bluffcatch here with 99 and take a note on what he does this with here, also he made it under half pot se he's giving us a pretty good price to look him up.

Hi, for the action i like call river, maybe this villan bet any draw fail or 7cxc 6cxc, etc, i not think thaht villain make check in this turn with As

Not sure if I'm to happy cbetting this type of texture. Think it's ok considering we're UTG and we are perceived to have a lot of Ax in our range. Problem is once he calls we're not to happy to proceed most of the times, like now. I think our line is ok but we can't really call any reasonable sized bets on later streets.

Player dependent but generally fold. You should check your weak aces to bluff catch here that can beat him if he values KQ and also redduces the chances he has an A

All looks fine to me. We could just take the other route of turning our hand into a bluff and betting 3 streets.
