You don't want to drive him out, you just want to give him the wrong price to chase his draw but hope he chases anyway. When you bet so big that you force your opponent to fold his draw, all you've done is help your opponent make the right decision.

Instead, you want to figure out the maximum to bet that will still get called by villain. Of course, villain won't always be on a draw here, but if villain is on a draw, you don't want him to fold.
