I don't really think of a raise with 60 big blinds behind with T9s from the button to be stealing. It's simply a combination of fold
equity and showdown equity which make a preflop raise profitable. If they call more and 3 bet less from the blinds when I raise, then I open raise quite wide. If they 3 bet more and call less, then I tighten up preflop a bit from my default ranges.
With shorter stacks, I raise less often, but when I do raise then I'm shoving at <18 big blinds. The shorter my stack is, the more often I shove.
