That may be true, but it doesn't change the fact that it's just an inside english shot with aim corrected for squirt.with a slight inside strike you won't have anything resembling english on the cueball for more than a few rotations before the cloth straightens it out and if any "is" left at contact the contact induced spin negates it...
If he miss-hits the cue ball, even if he's purposely trying to hit a little offcenter, he can miss the shot just as badly as with a centerball attempt.Basically what he is doing is hedging to make sure he can never under cut the ball... At worst he makes it where he aimed....
This shot is just as sensitive to speed as any similar sidespin shot - if you hit it too fast it can squirt to far; if you hit it too slow it can swerve too far.This technique also takes speed sensitivity and tosses it out the window. You can misjudge speed and the ball still finds the pocket.
Believe it or not, I've actually hit a few centerball and offcenter shots. The only thing that makes this shot seem unusual is the way it's described.You should actually try something before dismissing it
