This happened on the very first hand of the tournament. I knew my jacks were way behind hence the fold. I kick myself for not calling now but I think I made the right move. Any thoughts???

You did the right thing. I know a lot of people who push with jacks, because they seem to be so vulnerable. Two all-ins after your raise told you just were you were. Good move. Leave it to online poker to give you such a strong hand, yet still be third preflop. Only three hands have you beat, and two are on the table.

definitely a good fold here! But, with all do respect, why get so aggressive with this hand in the first place, on the FIRST hand of the tournie? I think a simple call here is just fine and a fold is definitely the right thing to do if repopped. I usually don't get too aggressive with this hand til later in the tournie, just not worth it so early in a tournie. 

would have been hard to toss that hand, but i agree, i usually play slow up front till a few are out, then come in aggressive.
