As long as you bet at least the amount that makes it incorrect for her call and less than the amount for which she will fold, then your bet is good. The highest you can get this amount is the best bet you can make here. If you KNOW precisely what draw she holds, then you also KNOW not to pay her off on the river. That kills her implied odds. Since this is most often not the case, you will need to aim for the high end of the bet size in order to attempt to kill implied odds.

EDIT: Perhaps your subject is throwing people off, as it isn't very descriptive.
