Actually I've used pressure points in my matches and even in real life situations. I remember watching this show and I was so impressed with the way she jabs with her fingers and half-clinched knuckles, because some points are buried deep in the muscles and a simple punch will rock it but it won't affect it. A jab pushes that smaller point in hitting that nerve or artery and it will hurt a lot.

Will a few jabs knock someone out? They can, but like Braeden has said, the person can resist and that lessens the force of your strike. So yes, it is possible, but it really depends on the situation of the fight.

Yes its possible hard an very pointless but possible its a wing chun exclusive tai chi would practice it too i imagine

There pressure point attacks...it is possible to do if there not resisting but if there fighting back its VERY unlikely to work

Basicially that she does is gives a couple of quick jabs to either incapacitate or knock her opponents unconscious. Is this possible?
