99 in CO facing re-raise from SB. What's my play?

[JoshNjuice]

This is a Party $50+5 freeze-out. 538 entered, we're down to about 40.

My table image should be pretty tight/solid. Since I moved to this table on the bubble, there have been multiple people to several flops, lots of re-raising, etc. I have tightened up and haven't been stealing, etc.

Reads: All three of the players to my left have been very loose, alternating between passive and aggressive. They've shown down some mediocre hands and often cold-call pre-flop raises. That being said, I've only seen a few instances where they've thrown in a re-raise.

What's my play here?

Blinds are at 1K/2K-75

Thanks

I think stacks are too small for set value, and I think this is something other than QQ+ like 1/100 times.
