Martial practice=position, position, position
It's very easy to forget in competition your innate resources.
It's very easy to configure your options based on context alone.
If another person has a dominant or controlling position over you, your options, based off of that context, shrink.
Your limited resources are time and energy.
In a lousy position, if you can remember how much you trained to have energy resources, you explode and use them.
The psychology of your position matter.
You may not be flattened out by anything other than your own forgetfulness.
Train to remember.
Train to not flinch.
Train to not lose consciousness.
Train to remember on what you rely.
Train to stay connected to what's really important, under pressure.
