The Deciding Factor
The above image displays what I like to call "The Deciding Factor". This diagram is used to determine which player strikes first in any given exchange. Translated into a readable form, the image means; High Punch & High Kick beat Mid-Punch & Mid-Kick, Mid-Punch & Mid-Kick beats Low-Punch & Low Kick and Low-Punch & Low-Kick beat High-Punch & High Kick. Think about the game rock, paper, scissors if you're confused. Rock beats Scissors, Paper beats rock, so on and so forth.
