Edge aiming
- Thread starter LAMas
- Start date
Edge aiming or fractional overlap aiming as most would call it is probably the 2nd most common way of aiming on snooker, first would be ghost ball. It was how I was taught as a kid, just the basics or 1/4, 1/2, 3/4 and full ball contacts.
Rather than lining up the edge of the cue ball and parallel shifting to centre, users generally recognize the angle of the shot. For example, you recognize that the shot is a 3/4 ball overlap. Instead of lining the inside edge of the cue ball to the inside 1/4 on the object ball, players recognize that for a 3/4 ball overlap, centre cue ball is aiming at the outer 1/4 on the object ball. 1/2 ball you aim at the outside edge, 1/4 ball you aim 1/4 of a ball outside the outer edge and so on. After a while you stop needing to establish the overlap, and from memory know where to point your cue to make the shot. The same goes for all the overlaps in between the major 7 or 8 fractional overlaps. You recognize the angle roughly, so you think this looks like a 1/2 ball hit and as you get down you make minor adjustments to compensate.

Lamas... out of curiosity, would you mind explaining the steps in shooting a particular overlap? Lets say 3/4 overlap as an example.
Start with sighting and end with cb address.

I concur, but the parallel shift is the nut and can be a degree or so off and affect the presumed shot.
Hi Dave,
I would use stick/cue aiming and while standing, I stretch my cue with my elbow at my side and aim the tip from the edge of the CB to the fractions on the OB.
That could be 72" (assuming a 58" cue and a 14" forarm) from the tip of the cue to the elbow and one side of an isoseles triangle. The worst case would be the 90 degree cut where the cue would arc from the elbow from the edge of the CB to its center or 1.125".
The other leg of the isoseles triangle would be when the cue is pointed to the center of the CB creating side A of 72", side B of 72" and side C of 1.125" or the included angel between sides A and B would be .895 degrees or less than 1 degree.
Unfortunately, this is not quite the desired parallel shift and as the CB travels down table the .895 degree will send the CB far enough away from the edge of the OB and barely miss contacting it. One could move his stance and cue butt 1.125" to the side toward the center of the CB where the tip and bridge are now aimed, adjust the bridge back to center, to decrease the .895 degree error.
Now drop down on the shot and shoot the center ball hit on the CB and compensate for the CIT.:smile:
The thicker cuts will require a smaller than 1.125" arc or shift and the straight in shot requires 0 inches or no arc or shift.
Thanks for your question and be well.:smile:
Thanks and be well.
That certainly sounds a lot simpler than CTE/Pro One.
I'm not sure why At Large doesn't chime in and explain how a 1 degree difference would cause you to miss those shots. As simple as all that sounded, I can't see how it could put you off by as much as a degree.That certainly sounds a lot simpler than CTE/Pro One.
The hard part is associating the visual or perceived angle with the edge of the CB aimed at the various fractions on the OB. What I like is that on thin cuts the edge of the CB is always lined up with some fraction on the CB, while aiming with the center of the CB will be off of the edge of the OB somewhere on the cloth or rail.
I also use GB, DD and CP to CP aiming to double check the final location to see if it looks correct.
WIth time at the table, one can master the CB edge to fractions on the OB aiming for all cut angles for himself for we all see things or stroke a little differently.
Be well.
With all the protractors, calculators and alternative double check systems you employ, it must take about an hour for you to run a rack of 9 ball. LOL

How do we even make a 90 degree cut ...sometimes.
That one degree ends up being 1.5" when the separation between the CB and OB is 8 feet apart...big deal. It works OK when the CB and OB are close to each other but when they are far apart, I try to acheive the parallel shift with the butt of the cue.
With time at the table and shooting the 90 degree cut a million times, one can adjust for that .895 degree.:smile:

Sounds like a really faulty aiming system to me. Lots of perception, lots of subjectivity, parallel shifts, acute angles ... wow. And I thought other aiming systems were so simple. Shame on me.
Edge aiming would be very cool if the OB didn't appear smaller then the CB.....but it does....which complicates it - since you can't just imagine a perpendicular line, on the 2D CB image, going from its edge to the desired fraction, it has to be an angled line.....how do you use the edge aiming then????
That is the real question.
That is the real question.
Not fair, not nice.
Funny how the CTE/Pro One users can heap shit on other system users, but if we dare to make a single negative observation about CTE they cry foul and we are characterized as "Haters".
Arrogant comments like these are the reason why I basically stopped contributing to the forums here and mostly just lurk like I used to. Just ain't worth the mental aggravation.
Carry on with your CTE forum (s'posed ta be an "Aiming Discussion" forum). I won't be back to reply.

Can't take a dose of your own medicine huh? I could care less about Las Mas edge aiming system. Just giving him back what he so often does to CTE/Pro One. And predictably, I get your post. My next post was going to be for him to post the math proofs for all the aiming steps with his edge aiming.
Dish it out but can't take it. Thanks for being so predictable.
I have a friend who is a really good shot maker who does something similar. For cuts up to half ball hits, he aims the center of the cue ball at the contact point. If it is more than a half ball hit, he aims the inside edge of the cue ball at the contact point.
I think if you aim center CB at the contact point you would under cut the ball. Your friend would be making some adjustment from the line.

Yes, or either the friend isn't picking out the correct contact point. A lot of players struggle seeing a contact point without standing behind the OB and pocket, so through trial and error have engrained the wrong contact point in their memory so they can aim the centre of the cue ball at it and still make the shot.
Is it possible that he is only aiming the center of the cue ball at what he perceives as the contact point and not actually trying to hit the contact point with the center of the cue ball?
Yes, that's what I meant by my post. I'm sure if you asked this player where to aim a half ball shot he would say the outer edge of the OB, but the outer edge is not the contact point. He may have a different meaning of contact point, by that I mean he may think the centre of the cue ball contacts where he is aiming, but it isn't the case.
I use the edge of the cue ball on shots that are a half ball hit or thinner. A pro friend showed me this several years ago. It puts a slight over cut on the object ball.
As far as contact point aiming, I compensate for the under cut with a simple reverse double the distance aiming method using the edge of the cue ball. It too, slightly overcuts the object ball. I use it on thicker shots less than a half ball.
Best,
Mike
