NLTRN - A Deceptively Weak Hand

[Dromar]

$100 live HU match (so no converter). Villain has shown a tendency to fold too often OOP after calling preflop. Also, based on the few showdowns I've seen so far, he's willing to call preflop with pretty much anything suited and/or connected if he feels I'm weak. Beside those leaks, he's pretty strong unfortunately.

Blinds 10/20.
Hero t1055
Villain t 945

Hero is SB with 3 [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/heart.gif[/img].
Hero raises to 80. Villain Calls.

Flop: 4 [img]/images/graemlins/heart.gif[/img]2 [img]/images/graemlins/heart.gif[/img]2 [img]/images/graemlins/spade.gif[/img]. (pot = 160)
Villain checks. Hero bets 120. Villain thinks, pushes for 745 more. Hero...

1. call or fold?
2. what range would you put villain on?
3. critique preflop raise and bet.

I'll post my thoughts later on.
