I like this thread, and I think this point here is very useful as I used to try to aim to contact point and visualize the round edge of the CB hitting it. What I've been doing recently since getting back into the game, and I got this mostly from Dr. Dave and his colleague (Mr. Jewett, I think), is to use ghost ball analysis and translate it into a fractional aim point. I consider myself a beginner but see the value of doing this, and I've been improving in my shot making. I've also read Poolology and see value there... just need to put more time into that.
Here's how I do it: Stand with my eyes on the line directly behind the OB pointing to the desired pocket/target) and place my cue tip on the table pointing at the target at a point 1 1/8 inches behind COB. Then, with tip still on the table and cue suspended from under the butt end with one finger, walk the cue shaft to a point directly over the CCB. Now, the center of the cue tip is pointing directly at the OB under the aim point. I identify the fraction (1/2, 3/4, 7/8, 3/8, etc., or visualize somewhere in between), which is easy, then step away from the table and do the pre-shot routine with this knowledge in mind. When I step into the shot I know where the CCB needs to hit the OB.
I've noticed that when OB is near the rail, I need to subtract about a 1/4 fraction to avoid cut induced throw from sending the OB into the rail. Also is this okay etiquette to do in a match (I play at home for fun only).
Does anyone see anything wrong with my approach or can anyone add any pointers to what I'm doing?
Thanks!
Good approach. And you can even catch pro level players occasionally lining their cue up with the tip planted behind the ob. I wouldn't think anything of it if U were playing someone that did this in every shot.
