It really depends on a lot of factors. How many blinds I have, how was the action before me, how many players are left to play, how deep in the tournament. Depending on the situation I'm not confident even with QQ.
It really depends on the current stack size. When short-stacked you can not wait for 99+. With less than 10 - 5 BB you have probably shove with any pair. Sometimes I do not feel comfortable shoving with JJ because bigstacks probably call with Ax, Kx or even Qx.
