[Slap My Jack]

Doesn't seem to matter if you have queens, jacks, or tens here. I think if you made it TT, people would fold more easily (Although you do seem to have an increased edge vs AK, but it is very tiny.)

Major tournament, sure, fold. I've folded these during the first hands of some online tournaments, and sometimes I've taken the flip (More likely for SNGs where blinds move faster).
