Okay, I have JJ and I'm first to act (UTG) Preflop.  I find this to be a dangerous hand and I know it's one of the top ten, but to have this UTG is an ackward decision considering that I'm either facing AA or maybe 88 in a later position.  Do I 4BB, 5BB, 3BB, call and whatever decision is made, what percentage of my stack can or should I risk? I know I don't want to end my tourny with this hand and lets say I'm average stacked (Comfortable)  I'm just curious to how people play this hand preflop.
