overpair vs TAG

[teamdonkey]

villain is 16/6/3.5 over a large number of hands and is fairly decent. He's not shy about re-raising preflop, but
being in the small blind here might stop him from repopping some of those hands, my read isn't that specific.

he's aggressive enough postflop that i think i'm still ahead of his range after his flop raise. how to proceed?

$1/$2 NL 5 handed

button ($245.55 in chips)
Villain (SB) ($194.45 in chips)
bb ($147.48 in chips)
utg ($68.28 in chips)
Hero (CO) ($437 in chips)

dealt to hero: J[img]/images/graemlins/spade.gif[/img]J[img]/images/graemlins/club.gif[/img]

UTG limps, hero raises to $10, 1 fold, villain calls $9, 2 folds

Flop ($24) - 5[img]/images/graemlins/diamond.gif[/img]8[img]/images/graemlins/club.gif[/img]8[img]/images/graemlins/spade.gif[/img]

villain checks, hero bets $20, villain raises to $50, hero... ?
