Johnnies b4 the flop

in a tournament where you are have 3100 chips vs an opponent with 1400 chips you are dealt JJ and raise before the flop, the flop comes K 6 3 rainbow.
1) SHould you automatically raise?
2) if you do, should you call an all-in reraise by the villain?

you suck at posting, let me help you out. you need to post the blind sizes, any antes, your position, you opponents position, how much you raised before the flop, how your opponent plays, any previous history between you two, and how the table was playing in general, and if this hand occured in or near the payout spots and what they are. i probably forgot somethings. also, this forum, heads up/shorthanded deals exclusively with limit holdem, not no limit. try posting in the multitable tournament forum or the single table tournament forum. good luck.
