$12/180man SNG - Another easy push?

[bruno_pro]

I've been trying to work on my pushing ranges lately and this should be an easy push, as I think it is... what I really wanted to ask is: Does the presence of the big stack on BB lead us towards folding more hands on this spot? What should be my pushing range here? I really don't know the answer, but my instincts tell me that pretty much any two cards will do it.. is that right?
