This. And to be more specific, you have be aware that when you are moving into the shot, you are not aiming at anything. That is a very foreign concept, you'll only begin to understand after going through the motions.
That's the part that makes no sense at all. I see the two lines, no problem but then I put my bridge hand down somewhere. How can you put it down in the proper spot if you aren't aiming at something somehow? If it's not in the correct spot then after pivoting the cue tip will also not propel the cue ball in the exact proper direction to pocket the ball center pocket. You must be aiming at something, to do this or you will never put your bridge down in the correct spot. I understand your tip is placed down a half tip one way or the other but at what angle? None of this makes even a tiny bit of sense and I have now watched the video at my table and tried to do what it says but this one detail seems to be left up to something other than science. Isn't that how I aim now using ghost ball and fractions? By guessing where to start?
