I just finished Every Hand Revealed by Gus Hansen and in it he is talking about a short-stacked opponent and says:
I should probably watch out so I don't give him too many perfect all-in moves before the flop. It is imperative to manipulate the size of my pre-flop raises so that [he] either has to over-commit his chip stack for a small gain or else he will simply have to see a flop.
Can someone explain the math behind this type of move and how to calculate the cut off bet between giving your short stacked opponent a perfect all-in and forcing them to over-commit?

The following example (adapted from the book) is what alerts Hansen to make the above quoted statement.
Table is 7 handed Blinds and Antes: 15/30/5 Seat 1: Gus Hansen with 4,800 BB: Villain with 450
Button opens with a raise (amount not specified) and
Villain pushes all-in. I'm assuming Hansen's concern is for when he is on the
Villain is now in
Seat 4. How much should he raise to make moving all-in a bad move for
