[SnG Strategy] - Stealing and Blind Steals

[Aequitas58]

Here's the scenario:
A random $6+.50 SnG on Stars, 4-5 players left. Although "turbo," the usual rules apply, as 3 places are paid. We should assume, for the sake of argument, the SnG was initially filled w/ 3-5 fish, 2-3 competant players, and 1-2 good SnG players. (Hopefully, I'm one of the better players ... LOL.)

Obviously, we need to make blind steals. When we're down to 4-5 players, the blinds can easily be up to 75/150 (or more) so we have to find some way to build chips w/out showing down.

Chip Counts:
Of the remaining 5 players, the chip leader is sitting comfortably w/ 4-5k. The guy in second place is doing well, w/ ~3500. The remaining players (including yourself) are just about even. I find that this is a common situation... two people are ahead and three seem to be battling....

Specific Situation:
Sandwiched between the chip leader (BB) and the guy in second place (Button), I hold KJs in the SB.

Action:
Folded to the button, who bets 3.5x. Smells like a steal, right? Although KJs is not premium, I feel like it's strong in this spot. (DO YOU?) I reraise all-in. First of all, I want to raise (DON'T YOU?). Second, I can't raise anything substantial b/c of my stack. Doubling the raise is more than half my stack, so I pushed. I don't know if this was bad or not.

BB folds, Button insta-calls, flipping QQ.

I'm out.

What general criteria do you use to pop someone back? Keep in mind the situation ... everyone is stealing! (At least it seems...) So, was this a terrible move w/ KJ?
