Three keys to unarmed combat

There are 3 fundamaentals that need to be considered to sell unarmed combat.

1. The Reality - what is being done, the action/reaction/response
2. The Trick, the artificial aspect that is added to the above to make it appear real to the audience. this is how you sell the illusion to the audience, the knap, vocal sound of pain/impact/injury,  misdirection  etc.
3. The Angle, the way  that you stage the action to the audience, so they see the "reality" to its beast effect and at he same time how you hide or mask the tricks from the audience.
