The fence

will be crushed and you attacked as a consequence.
It is important with the conscious fence to create a gap about
5 feet would be good -between you and the assailant. You
can do this by stepping back (or pushing him back if you
can't step back for some reason) away from the attacker,
whilst simultaneously using your lead hand to shove the
attacker so that he also goes back. You can also create a gap
by using a slap and step back, a two handed shove or a Thai
leg kick. Any approach will do, as long as after the contact
you create a gap between you and he.
