A tough 55 Party hand

[adanthar]

The flop gave me two ways to play this hand. I don't really want to say which way I picked yet, so one of the choices has been modified a little from the way the hand went down.
What do you do in either situation?

Villain in this hand is a bit loose. He's limped K9s in EP with 700 chips left in level 3, raised a minimum bet from the blind to 100 on a KT2 flop, then called the all in (for another 500 chips) and doubled up when the BB's T2 was counterfeited. On level 4, he CC'd a 300 all in and call in front with 9's and doubled up again when he hit a set. That's about the extent of the action thus far.

Again, I'm not saying which one of these is the real hand or what the BB had yet. What would you do here?

(2.5: In variant 1, assume you both have another 2000 chips apiece, you call the CR, the king hits the turn and BB goes all in. Do you call? In hand 2, assume you call, a blank hits the river and BB goes all in. Do you call?)
