Deep in a Party $109, blind defense vs big stack?

[billyjex]

We are down to 12 out of 139.

Villian here seems decent. He has opened a decent amount of pots since we got down to the last two tables. He's not going crazy or lagging it up completely but he's stealing probably 1.5-2x an orbit.

BB is chip leader and is pretty passive, especially preflop but postflop will only bet with something good.

My image is probably pretty taggish. The only hand I have showed down was KK in a 3-way all in.

Call, push, or fold? I'm thinking folding's not an option.

BTW the payouts are 1st - 3.6k, 3rd - 1.5k, 5th - $950, and not much after that.
