Those sorts of brash controlled moves can work, if you can close alot of distance and do it quickly. Drop stepping, for example, tends to do that pretty well.
However, you did slightly misunderstand.
My point was that trying to lunge or charge in dont work so good unless the format of competition permits it, or, as i often adore doing, if youre already in something of a medium range. Then the charge is just for momentum, and nothing else. You do plant your feet if you can, but you dont really need to in order to generate power. You just need to to generate more power. For what its worth, the thing about striking before the foot hit the ground came from the OP, not me
"
Any type of advancing footwork can be used to increase power in a strike. Be sure that when your advancing for attack that your lead foot does not land before the strike."
