Longest weapon the closest target
This is a combat concept.
It means what it says:
Use your low lead kick to hit the opponent's leg as he steps into range.
Use your lead jab to his face, or eye jab to the eye as he moves in.
Lin Sil Die Dar
This is a combat concept.
It means similtanous block and strike.
We have various ways of practicing this.
It's harder to do, but more effective than "block then punch".
That "coffee table" moment
This is a combat concept.
You have all had that experience where you've "barked" your shin on the coffee table when crossing the room in a hurry. It makes you forget what you were originally rushing to do and focusses all your attention on the site of the pain.
In combat we strike kokutsu, the shinbone, with a hard kick, to give him that "coffee table moment". It makes him forget all about attacking us.
Buffalo eyebrow
This is a combat concept.
One of our primary concepts is that we defend angles of attack rather than worry about specific weapons or what style the attacker trains in.
The strike that comes in to the left side of your head is angle #1. You defend it with the appropriate block.
It doesn't matter if the attacker is:
a "street fighter" throwing a haymaker
a boxer throwing a hook
a karate stylist throwing a shuto
another stylist throwing a ridge hand
throwing a crane beak
throwing a "buffalo eyebrow"
or anything else
"Buffalo eyebrow" is of course made up. It's not a real technique (as far as we know!)
It provokes laughter when we cover this concept in class and that helps you remember it.
