Im not as experienced, but #2 PUSH looks bad.

1. You have pretty much zero FE. The guy raised more than 1/3 of his stack in early position. 550 chips is low at this point and hes probably gonna wanna gamble.

2. In a cash game, this could be +EV as someone suggested, but its different in a tourney.

a) you push and WIN, go from 1000 -> 1500 chips, not THAT big a difference.

b) you push and LOSE, go from 1000-> 500 chips, a HUGE difference because your now in terrible condition. You have just lost a huge amount of FE.

I would fold, but the stop and go sure looks tempting =).
