Live 1-2, KK played too weakly?

[deadmoney98]

I really did not think villain had a queen, and for whatever reason thought he had a hand like 99. I guess I just don't really see what betting accomplishes other than the obvious, which is taking it down right there, obviously an acceptable outcome. With bottom set in Villain's position, I would look to checkraise sometimes on the turn after that flop action (probably not in this particular game, but you get the idea.)

Anyway, what worse hand calls if I bet on the turn? Against most players in this game I would bet/raise all streets, but I just felt like I was WA/WB here.

Edited to add: His flop bet was a little bigger than the table standard, so I kind of felt like he was trying to end then hand right there, which his check on the turn helped to confirm. So why not check behind and let him take another shot on the river?
