$11 PP Push or Fold?

Played the first few hands of the tourney and won one pot, then my internet connection went out for about 20 minutes, then it came back on when the blinds were 50/100 so I have no reads on these people, so push or fold?

Without any reads and the BB still to act I'd fold, but that's me.

i'd fold, your M is close to the limit but with a4 i would say you would want to be first in and not calling

EZ fold. A4 isn't that good calling and you want as much fold equity as you can get for future hands.
