It would be useful to know the buy in and prize structure.

Unless this was a life changing tournament (e.g. top nine qualify for the WSOP) or where the 9th place was really WORTH winning I would not be folding here.

JJ is a top 5 hand - you do not win tournaments by folding these hands - I assume you are in it to win and not just finish 9th?

Firstly there is a raise from the big stack - I doubt he has a hand and is most likely trying to bully everyone else on the bubble to obtain a bigger stack that he can use to win the tournament with.

What do you know about the big stack? - good player? lots of standard pf raises? use this information to help your decision.

I am assuming that he has raised at least 3xBB = 6k making a pot of about 10K.

If you win it you will have 33k and be in a good position.

You have to use the information available about the player you are up against - but if this smells like a steal I push all in - and he will probably fold giving you the pot.

Even if he has a hand - only 3 hands are favourite against you and I doubt he has one of these - you are slight favourite against AQ, AK and 70% against AJ and lower, and 80% v lower PPs.

SO IMO - PUSH

A more conseravative play may be call - hope the flop comes low and then push - but the problem here is that you do not know where you stand if an overcards comes.
Folding premium hands may leave you close to bubble pushing hands like Ax - so take your chance now.
