B&M dilemma

[ZootMurph]

I'm playing 1-3 max $300 buying NL at the local casino. I'm BB. SB is very loose and aggressive. If he's in a hand, he's betting big or raising.

Folded to SB, who raises to $6. I call with 88. Flop is 8[img]/images/graemlins/diamond.gif[/img]Q[img]/images/graemlins/diamond.gif[/img]5[img]/images/graemlins/heart.gif[/img]. SB bets $20, I smooth call. Turn is 9[img]/images/graemlins/heart.gif[/img]. SB bets $60. I have SB covered by about $350 for him to $450 for me, before his $60 bet. I put him on a Queen or diamond draw. The pot is now $108 (after rake). I make it $150 to go. He goes into the tank, and finally calls. I have a tell on him and I'm SURE he is Hollywooding a big hand. I'm pretty sure he has JT. The river is K[img]/images/graemlins/diamond.gif[/img]. He checks. I'm pretty sure I'm beat and the only way to take down this large pot is with an allin bluff. Should I do it?
