to call or not to call? That is my question....

[ThaSaltCracka]

NLHE freeze out tourney last weekend. We were down to 30 players after a start of 40, My tournament was going pretty well until my pocket kings lost to my buddies AK, oh well at least it was a friend. Anyways after moving to 3 tables I had about 675, out of 1000 left. I was dealt KTo, UTG+2, blinds were 50/100. UTG calls, so do I, everyone folds to Button who calls, SB calls.

flop was Jx 9x 8x, suits aren't relevant, runner runner for any possible flush.

SB & BB both check and UTG goes all in for 475

what would you guys do here? am I short stacked enough to call this? I am at the point stack wise, where I should definelty be trying to double up.
