6.50 turbo, wait 1 hand or push

I have pushed successfully several times now. The two bigger stacks don't impress me with their play. I know I beat a lot of hands, but I am worried about getting called. What is the standard play here? I only have to wait one more for shorty to be all in by blinds.
