87s early in live tourney

[Airharley]

This is an older hand that I didn't post before from the Circuit event in San Diego. First event, $300 buy in, 660 or so start, we're past the first break, I think the 4th level. Blinds are 100/200

Relevent stacks.

Hero button ~7000
SB ~12,000
UTG ~7000
MP ~6000

Hero is Button with 8 [img]/images/graemlins/heart.gif[/img]7 [img]/images/graemlins/heart.gif[/img]

Reads so far, SB is new to the table, so no real reads but he seems like a thinking player since I've watched him play a few hands. UTG and MP are both weak tight players who like to limp, but have continually folded to cbets from myself and one other player. My image is probably on the aggressive side, but I've shown down some good hands, and tripled up early with pocket tens that hit a set.

Action:
UTG limps, folded to MP who limps, Hero limps, SB raises 800. UTG, MP call, so I call. (I'm a sucker for suited connectors I guess, right move to call?).

Flop: Q [img]/images/graemlins/spade.gif[/img]Q [img]/images/graemlins/heart.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]
Pot (3400)

Checked around to Hero, (reads: UTG, didn't seem to like the flop, no reads on others cause I wasn't looking at them.) Hero checks.

Turn: 3 [img]/images/graemlins/club.gif[/img] Checked around to hero again. Is this a good time to bluff at this pot? If so how much? I'm sure my 7 is better then UTG, but a little worried about a pocket pair better then 7s or slow played Q.

Comments on all streets appreciated.
