We all like to see a flop with KJ. Calling the raise was OK. Calling the all-in would be a marginal play at best. You are almost surely an underdog. Do you expect anything less than Ax or pocket pair?
But you aren't just calling a short stack all-in. There is another caller. You are no doubt a huge underdog against 2 opponents.
Then, after the flop, you just fell in love with TPGK. Board reads J66 and he checkraises your big bet. What did you put him on? Here's your biggest mistake... you played your hand and didn't put him on a hand! He likely has trip 6s, set of Js, AA, KK, QQ or AJ. And of these you can still only beat AJ and QQ if a K hits the turn or river.
The only thing you have beat is Jx (worse kicker), flush draw, pocket pair T or less. Unless you read him as a terrible player, these hands are highly unlikely. Would he have called the all-in PF or check raised the flop with these marginal hands?
To summarize:
1) KJ is a big underdog against an all-in and a call.
2) TPGK probably isn't good enough after getting check raised.
3) Now he comes out with a big bet on the turn.... run away fast!

It looks like you were doing well in this tourney. You can't throw it all away, falling in love with this hand. Eliminate these types of mistakes and you will improve greatly.
