JJ level 1 play

[TheAmp]

Hi all,
You are delt JJ in level 1 Sng (50+5 on party), and raise pre flop 5X BB .level 1 can be dangerous because usually there is no read.
what do you do if :

1) one player pushes all-in? how often do you call?
(assuming no reads on the player)

2) one caller ahead of you (he called the completed your raise). flop has one overcard (lets say KT6 rainbow). he bets into you. raise or fold? what do you want to do in this position?

3)one caller ahead of you? not more than one overcard. how often do you bet? (and how much). what do you want to do in this position?
