Black Tiger Steals Heart - 7 Star

[ursa major]

I have been intrigued by this method, "Black Tiger Steals the Heart" since I first heard about it. As far as I am aware it is specific to 7 Star but I am no authority on this.

I may have been practicing this method for several years without knowing it as I was not taught to associate this classic name with any given form, method or technique.

I would very much appreciate it if someone could enlighten me on what it is ? Does anyone know what it is or in which forms it shows up in ?

Also, what are "8 Forbidden Strikes" ? Is Black Tiger Steals the Heart one of them ?

Also, do we know how Black Tiger system got into 7 Star (or PM in general ?) and what is the distinctive characteristic of Black Tiger ? I am aware that there is a "Black Tiger" system, is this where it came from ?

thx in advance,
UM.
