Open fold JJ here?

[Gamblor]

18 left, live $500 tournament.

Pay structure is top-heavy, with 70% of money going to first 3 spots, only 4 more spots pay.

I'm 3rd biggest stack at the table with T33,000.

Blinds 1500-3000. I've raised 3x this orbit and stolen the blinds with marginal hands.

9 handed. I'm UTG with JJ, biggest stack in the tournament, an intelligent but slightly too loose player is in the BB. Most stacks are between 15000-25000.

Standard raise = 3x the blinds.

What's the play?
