[2+2 Junkie]

grunching.
I 3-bet here, even if someone else has a K, which is unlikely, our kicker may not ever come into play, du to a pair on the board, or overs to the other guys K come out. The raise could be a flush draw, the original raiser could have QQ, AA, JJ, and thinks that since there are two kings out that you don't have one. I vote 3-bet here.
