Ok I just found and looked through the HH.

Villain has checked OOP in same type of situation with a weak ace as top pair. checked the turn and minbet the river when I checked behind turn.

He's also checked down with top pair in another hand, not the same situation as the last two but he's definitely not value betting his pairs hard, regardless of TPTK or 2nd-3rd pair.

It's debatable if he does this with two pair on the turn, but that probably doesn't change our decision with a weak ace through QT type hands from being the same to different imo.

The strongest single pair I expect him to bet on the turn is probably like 99. Maybe a T. I know that sounds/is bad but he is a bad player. It's quite possible he won't bet anything stronger than an 8 here, but that's a very error prone statement. I would, however, wager that his best pair betting the turn is an 8 before I would wager that his best pair on the turn bet is a K. If that makes any sense.
