First, I’m a passionate Judoka and it reminds me of this sport.
In Judo, you want to throw your opponent on the back and for this, you need to do your technique at 100%. The whole movement, with speed, strength and control until the end.
Even for a feint. A feint is only effective when the opponent believes in it, when you really want to take him down with the first move, when do it All The Way.
