Given stack sizes and blinds do I need to shove here? The bubble is coming up. What is my best play here? I am afraid I am beat and then I am just flipping. It's either all-in or fold here...is this a good place to shove under these conditions (22 players remain, 18 finish in the money). I realize ther are a lot of people behind me left to act.
