Villain has been loose-passive and there are about 30 people left.

Preflop: I think this steal play is kind of meh...but I figured I could at least isolate the limper if not get him to fold. People were limp-folding so much that I decided to take advantage of it this hand. After button min3bets, it's pretty easy to tell he has KK+ and will likely stack off with it. I called here what do you think?

Flop: I realize that with the money already in the pot and my hand, pushing all-in (about 5800 total) would be -EV chipwise. Also, if you account for the fact that the people in this play horribly, do you jump on this chance to triple up our stack? If I was to win this one, it would catapult me to the FT. But then again, we still have about 20BBs behind to play with if we fold.
