Right line for this calling station?

[TheDoubleA]

I am at work right now and do not have hand history. Sorry.

Villian is running at 50/6/.5, so basically he is a calling station. 2-3 rotations previous to this hand this happened:

UTG he calls
I raise to .5 with A7dd
all fold and he calls
Flop is A,x,x with a spade draw and straight draw
He ckecks
I bet .7
He calls
turn puts straight and flush out there, making most draws
We check it down and I win, he shows absolutly nothing, making me wonder why he would even call the flop

Now it is the hand in question:

He lims UTG for .1
I raise with AhQs to .5
all fold he calls
Flop: Ax Jh 8h
He checks
I bet .7 (again) and he calls.

(at this point I am sort of readless. He calls so much with nothing, that I am having a hard time putting him on a hand. I think that betting for value is the way to go unless a very scary card comes off.)

Turn: (Ax Jh 8h) (Kh)

He checks. I check. (I count that as scary)

River: (Ax Jh 8h) (Kh) (2x)

He checks. Hero????

(I think that if I check it down, I will win, based on the previous hands I have seen him play and we had almost this same situation. I feel like a bet his is ideal)

Pot: $3
I want him to call a bet with a worse hand, so i bet $1. Thoughts??????

He pushed for 5.50ish ove that bet. Hero????????


Sorry for the horrible format and long post, but any thoughts on all streets would be great.

Thanks

Against this type of player, you need to bet the turn. He could very easily have a jack or weak ace, you're giving him way too much credit by checking the scare card, you have a couple nice draws to fall back on, and you can always take a free showdown if he checks the river. As played, you can fold the river I think. A2 or something FTW.

Yea, I think I botched not betting the turn, expecially because I held the Ah. As played, I was half drunk (only one-tabling, not to worry) and called after a little bit of thought. he showed KK for a set of Ks, which was the last thing I put him on. I think that I could have come to the conclusion of folding there, but with a few beers and the fact that I was running over the table kinda lead me into a call.
