There is a concept that has been discussed in this thread that I have a bit of trouble understanding.

It is that one of the reasons to push is that you dont want to make a mistake if an overcard comes on the flop. Is this reasonable because you expect AQ type hands to fold? Do you think any of the villains in this hand hold AQ and will fold? Will they call holding AK?

I would just like this line of reasoning explained. Thanks.
