($22): Bubble play, when is shorty short enough?

[xJMPx]

I’m trying to get better at exploiting my big stack on the bubble, however in this instance I was a little hesitant because I wasn’t sure if the short stack was short enough to get the other players to fold anything less than a monster hand.

There are two consecutive hands below, the second one I was concerned with the fact he would raise into me a second time, although the previous hand was the first time I had pushed with the big stack (or at least had not pushed much.)

Thoughts?
