bobIf he lines up off-center but then hits the ball in the center to get the return to the tip, he is swerving his stroke. That will have to be different for changes in speed and stroke length. If he has to jack up, it's even more complicated.
I think it easier to play without a swerve in your stroke.
its interesting that you say this
so why did you not straighten out your stroke?
i recognize you did quite well the way you did it
