It depends. On a lot of things.

How has button been playing, loose? tight? stealing a lot? is this his first steal of your BB? is he capable of folding to a big reraise? what does he think of the way I'm playing? is he even thinking about that now?

Im probably leaving out a few things, but in order to figure out your own pushing range, you need to put your opponent on a range first. These kind of plays are typically a feel thing for me.

"is calling an option?" - I typically push or fold here, although some people might think a stop and go might be better.
