A hand that isn't very exciting

[edge]

Party 5/10 6-handed. Folded to me in CO with 2000 behind and 8[img]/images/graemlins/club.gif[/img]7[img]/images/graemlins/club.gif[/img] and I open for 40. So far, I'm playing very tight and aggressive preflop. SB reraises to 100 and I call. He covers me, and is a LAG.

Flop 5[img]/images/graemlins/spade.gif[/img]5[img]/images/graemlins/heart.gif[/img]3[img]/images/graemlins/spade.gif[/img] with 210 in the pot.

Checked through.

Turn 6[img]/images/graemlins/heart.gif[/img] with 210 in the pot.

SB bets 80.

Anyone 3-raise preflop with these stacks? His reraise doesn't mean a whole lot to me, especially since I opened from CO. How about the flop? If I bet and he doesn't fold, I probably have to give up. As for the turn, I just picked up some more outs, so is this one of those situations where I smoothcall to avoid being blown off my hand?
