How can someone shape their entire game around a submission?
Easy, the kimura is much more than a submission, it is a position. There is a common misconception with the kimura that it is solely a submission, the kimura can be used from bottom to sweep, from top to pass, from bottom to recover, from top to advance, as a transition between submissions and more.
The possibilities with this grip are virtually endless. Harry has sepnt hours doing the research for you. He has discovered the kimura from places people would never think to, he has unique finishing tactics from this position that make it nearly impossible to stop once the grip is achieved.
You see, when someone as talented as Harry has a goal to shape their style around one thing, they start to see things others don't. Harry knows that he can use the kimura grip from bottom or top and that he can link a multitude of other submissions from it.
