no longer does nage simply accept whatever the uke dishes out.
取方不再只是接受受方的出招。
since it is nage who determines when he is crossing the ma-ai point and arriving at 「critical distance」 he has no 「reaction time」 because he knows when uke must commit.
if nage closes the ma-ai (space) with uke, he will hit a point at which uke must either commit to his attack or back up.
如果取方靠近受方,他必需打击一个位置,使得受方必需反击或是防守。
the main thought of parallel ken is to control uke's central line all the time. one must create the situation that uke can only move backward.
平行剑首重中心线压制。务必要在角度及时机上做到让对方只能往后退。
the difference between this stage and the last is that in the last stage the nage allowed uke to initiate and then he led the 「attention」 of the uke via his own movement.
