What martial arts style is based around using the weak points on the opponent’s body when the opponent is attacking, moving, or defending? I’m not talking about pressure points, but using the opponent’s movement against them? Lets say the opponent were to take steps with the right foot facing forward and you attack a specific point on the body to harm the opponent or make the advisory immobile? Also the style uses the environment to his/her advantage and uses specific attacks pending on the opponent’s size, weight, and body type against them; during specific times of the day, week, or year?
I was thinking Tai-Chi, but I wasn’t sure.
