Your game plan as always should be to stay away from places where trouble is a regular occurrence if possible.
Get away from a potential situation if possible by being switched on and seeing the signs before trouble kicks off.
Then if that has failed look to control the situation by using dissuasion, talking it down be careful with your choice of words your tone of voice and body language.
Everyone has an invisible space that they consider there own space so try to control that space with your hands again not giving the game away.
Control the adrenaline, look for tell tale signs that trouble is immanent use an action trigger. A good one is ask a question then its also a brain disengagement.
Then if you need to hit them so hard there ancestors feel it.
If you haven’t finished it with the first shot fitness mindset and impact are the key ingredients!
Keep it simple!
