The vast majority of Kata Bunkai out there, simply will not work in a real fight.
It will work great in the Dojo, with a static “Karate Punching” opponent of course.
However, Bunkai MUST work in a real fight, or it is not Bunkai.
This is a VERY basic example of correct Bunaki.
Take the ideas and principles and extrapolate them out to begin to understand what your Kata / Patterns / Forms etc actually mean!
