PS $5.50s - Two JJ hands

[ronbo1964]

First hand, this has been a fairly tight table, with no one but the short stack playing poorly ... I am fairly certain I should be +$EV isolating the all-in from the short stack ... If I just call, I've put over a third of my stack in, so I think pushing pre-flop ir correct ... Opinions ???

Second hand, again a fairly tight table ... Opinions on calling the re-raise with Jacks, or should I lay this down and look for a better spot with still over 1000 in chips ???

Evaluating these hands after the fact, I feel my first hand was played correctly, but I should have folded to the raise in the second ...
