Two Live 1/2 Hands OOP vs tough opponent

[LooseAggressive]

This took place at the Borgata in Atlantic City. Directly to my left is a very good regular who is fully capable of mixing it up, three-betting light, floating, and overall making life a living hell. Only reason why I'm at the table is a fish with over $2000 in his stack. I've seen the fish stack off very lightly with very weak draws and hit. Great table, terrible position. Almost comically, none of these hands deal with the fish.

10 handed table 1/2 nl

Hand One
Hero is dealt 79 [img]/images/graemlins/heart.gif[/img] [img]/images/graemlins/heart.gif[/img] in the BB.

Two limps, the fish pops it to $7, 2 callers, I call $5, two limpers call $5.

Flop: J [img]/images/graemlins/heart.gif[/img] T [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] (Pot 42)

Hero Checks, 4 checks, Villain (Weak/Passive) bets $10, Hero raises to $40, 4 folds, villain calls $30

Turn 7 [img]/images/graemlins/spade.gif[/img] (Pot $122)
Hero bets $50, Villain raises to $100, Hero?

Hero has lost a couple of big pots and has been pretty active at table here. The good player that I talked about earlier and I have some history of playing back lightly. I look steamed (although I'm not) and have a terrible image.

UTG limps for $2, Hero makes it $15(standard open in this game) with AKo and $180 total chips, Good Player makes it $35 total, Hero should?

Good player has a large range here and I feel like he could be iso-raising me because of my recent history. However in his range would be big hands as well because he knows that i know that he knows blah blah level level. What move is most likely to maximize EV?

Sorry for the large post and I appreciate comments on all streets.
