$4/180 77 - M=11,5 after raise and call

[Parvex]

THis is prolly pretty basic, but I'm a cashgame player trying to add some MTTs to my schedule so I'm not that schooled with low stack situation and I want to make sure, I don't fall in the habit of doing some major mistakes.

I was palying very tight at the beginning starting to loosining up over the last few orbits and stealing a little more blinds. I also made a pot odds call after my steal raise with T9s was pushed over.
But the two villains are in their second hand at the table, so they should have no idea about that.

How good is a push in this spot?
