2nd nut gapstraight vs fishy limper - go broke here?

Villain is considered as fishy, no real history or hands but stack, action etc:

PokerStars No-Limit Hold'em, $4 BB (6 handed) by Hand Converter CG

UTG ($308.50)
MP ($489.50)
CO ($212.40)
<font color="#C00000">Button ($280.55)</font>
SB ($444.90)
<font color="#C00000">Hero ($561.40)</font>

Preflop: Hero is BB with 8[img]/images/graemlins/spade.gif[/img], T[img]/images/graemlins/club.gif[/img].
UTG calls $4, MP folds, CO folds, Button calls $4, SB completes, Hero checks.

Flop: ($16) J[img]/images/graemlins/diamond.gif[/img], Q[img]/images/graemlins/club.gif[/img], 9[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, <font color="#CC3333">Hero bets $12</font>, UTG folds, <font color="#CC3333">Button raises to $24</font>, SB folds, <font color="#CC3333">Hero raises to $68</font>, <font color="#CC3333">Button raises to $276.55</font>,

The small 3bet was because I wasnt really sure if I will stack down here vs this guy, who could possible have TK. If I reraise larger Im def. calling.

Thoughts please.

snap call not close, bbv etc

Pot flop, 3bet bigger, find the best way to get it all in, never fold. Second nuts against a fishy but relatively unknown opponent? You are way way way ahead a ridiculous amount of the time here. Get the money in before the ten on the turn makes you puke.
