Okay so I find my self short stacked through no fault of my own, it seems I always tighten up subconsciously as I approach the bubble.
I make it to the final table which is incidentally where the bubble is burst. (This is only a small stakes tourney, $3 90 player, but I'm a beginner so go easy.)
I'm short stacked, barr one player, at the table.
I'm in early/mid position with

I raise 3x BB which is 2/5 of my stack.
Seat 5 insta calls and then Seat 6 shoves.
I decide to shove with my J's...but was this the right move?
Seat 5 insta calls again the shove from the other player.
I end up 8th as my J's didn't hold up. what would you do here?
and any guesses on the other players hands...
Thanks.
