The same answer in any situation - it depends.

In a tournament, JJ vs a likely calling range of KQ, AK AQ - only has 60% equity - barely better than a coin flip.

Your equity vs a range of QQ - AA is only 10% - and with those premium hands included - your total equity VS his calling range is only about 32%! So unless it's a multiway pot where your being given 2-1 pot odds for your shove - it's a losing play in the longrun to shove your jacks. When your called your most often dominated or a marginal favorite!

I rarely 3bet my jacks- preferring to call. They are a good hand, and having to fold them preflop to a 4bet is a disaster - yet alone a light 4bet with 9s-10s.

Risking my tournament standing even as a 60 - 40 favorite is stupid IMO - there are way better spots to get your money in.
