It is not required to read top or any other book to understand the basics of such a move. It should be intuitively sensed that if you bet, an opponent may fold, and that in doing so it is preferred to have a drawing hand.
That's all there is to semi-bluffing, take a hand that has a chance of improvement, bet hard against an opponent you suspect to be drawing, have a weak holding, or will fold to such a bet.

hope this helps cause that is a way out there question
