the first time i got a rib broken during a fight was by someone with a much higher Dan than me 
i can remember switching between alpha and delta before kicking his shit in and winning gold
something about the look that i shot the guy made him very anxious must've looked to him like i actually wanted to murder him
gpt
the switch between delta and alpha can be defined by eye contact 
alpha for looking at the bridge of their nose to feign eye contact and mark up your target in the visual aquity and reflex phase then when you know you've got an opening you switch to delta and give them the i'll fucking eat your corpse eyes 
scares the absolute shit out of them with the subconscious tell from a predator switching to attack mode 

the reptilian brain is a fascinating thing
