Bubble hand...I know he's calling...Push or Fold?

[ZBTHorton]

44 players remaining, 40 places pay. Naturally all the money is at the final table.

Blinds are 300/600. Ante(75 I think) I'm sitting at T3000. In 40/44. To my left are three average stacks around 12-15K.

The table has been playing very tight as we approach the bubble. BUT, the player two to my left has called me on semi-steals everytime I've tried on this table and out flopped me each time. The appearance of the table is that although tight, the 'bigger' stacks have been calling the small stacks all-ins and blind steals almost everytime.

I am in CO with AJos. It's folded to me. Do I push here knowing he's going to call with anything decent? I have 7 hands before I am back in the blinds.
