De ai? I suppose you could call it such, I call it timing, but see what you mean. Ma ai does not mean back up so I fail to see that.
I can watch a boxer keeping ma ai and in the end get a warning for not fighting. Boxers are very good at keeping ma ai and most times in a circular fashion. All sensible martial artists use it and enter when the 'opening' presents itself or they cause one to.
The opposite of ma ai is not standing your ground so you lose me there also.
What do you do with a swordsman? Depends how good you are at keeping ma ai doesn't it?
Need I say there is physical ma ai, mental ma ai and spiritual ma ai? .
You are implying that your methods can handle a boxer?
Someone skilled in sword?
Is this what you are saying?
Can we get a simply yes or no from you?
