I would be extremely tempted to call...mainly thinking most remaining are "card dead" anyway and I'd have the "Best Starting Hand"...however, if the situation is a card dead situation, and another player has QQ,KK,AA....those Jacks aint looking good at all, and with the way you explained this situation, if JJ doesn't "hold up"...its the end of your tourney life...so after this very quick evaluation I would have, being put in the same situation, I would FOLD the hand, there's still more time left, and more hands to come.....not a "do or die" situation. And that's my take.
