Interesting QQ overpair hand - play along

[FreakDaddy]

I've only been at the table for one orbit.

Reads: (UTG+1) So far I have a slight read on UTG+1. He's VERY loose. I think at that point he'd played every pot, and I saw him stack some guys over pair a couple of hands ago by playing T4o OOP to a raise and turning two pair. After a few more orbits, I have a MUCH better read on this guy, but I didn't know all of that when this hand was played so I'm refraiing from adding more.

Reads: (BB) I have a little bit of past experience with BB. He's not very good, but not completely unreasonable. He plays way too passively after the flop, so it's always hard to know if you're ahead or behind. He plays some hands OOP that he shouldn't (his VP$IP is 25%).

Not sure what the f*#$ the flop check-mini raise is here. It could mean anything. It is very plausable he has a 7 though, but he seems bad enough to do this kind of chip spewing with anything.

BB checks, UTG+1 checks, Hero??

Ok, stop and go - what do we do here? I have to stick it in or check. I'm either Way ahead or way behind and I have no freaking clue what BB has. Let me know what you're doing and why. [img]/images/graemlins/smile.gif[/img]

After some responses, I'll add what I did and explain why.
