Party 400NL, valubet second pair meh kicker?

[Melchiades]

Villain just sat down, seems kind of stationy. Def capable of having floated flop with A-high but after he checked river my hand is most likely good. I'm slightly worried about valueowning myself against JT/QT/KT, will pocket pairs below the 9 call often enough to make a bet here?
