TEchnical crap
I'm hearing people on this forum say that talking all this technical crap is USeless?
That is the dumbest thing I've ever heard. I'll tell anyone, ANYONE right now that if you don't understand these concepts you cannot play great pool.
In answer to someone's previous post about collision induced deflection, yes when a cueball strikes abother ball, the CB stays in contact with the OB and causes some deviance, what I said though is that with NO SPIN on the ball that is the desired aim point. NOT the desired contact point. If you're using parallel shift then you need to manually adjust for that, but not when you're using aim and pivot or BHE.
Let me explain why. First if there is no spin on the CB at the point of contact the amount of time that the contact takes place is negligable, therefore the deviance is also negligable.
Second, when there is spin, the spin will counteract the effect by imparting opposite spin on the OB. For instance, if you apply right hand english on a corner shot into the far left corner the CB will be spinning CC. When it makes contact with the OB it does two things. First, The CB will maintain contact longer with the OB because the spin will throw the ball to the left , second, it imparts a slight amount of closckwise spin on the OB. Yes, this longer contact would normally cut the angle shorter; however, You have to remember that the contact point is no longer the same as the aimpoint because of squirt.
This compensates for the longer duration of contact.
Now for the usefullness of this knowledge. Anyone who tries to tell me that this knowledge isn't absolutely necesary in playing excellent pool, I will tell to go pound sand.
This is why. Say you have a nineball sitting in the middle of the back rail and you are shooting on the eight in the side.
You screwed up on your shape on the eight and are dead straight in. Now if the eight was sitting right in the pocket you could cheat the pocket for your shape but if you're 12 inches out and the CB is another 12 inches from the eight you're screwed. IF you understand all of these concepts then you know that you can aim straight in and pivot to the one oclock position on the CB and if you stroke straight through not only will the eight go, but the CB will follow into the far rail and spin up toward the right corner for shape on the nine.
This is just an example but for high level play you should know exactly where that CB is going to go and to do that you have to understand all of these concepts because the contact point will be different and therefore the CB will not follow the original Tangent line. Sure you do develop a feel for it and there is really no way to get around the necesity for some type of practice and feel; but to say that learning about these concepts is useless is asinine!
I thought for THREE YEARS that this system couldn't possibly work. I didn't even try it. Efren Reyes told it to me and I still didn't believe it. I'm sorry but you're wrong you can come up with all of the excuses in the world of physics for why it shouldn't work and why it should be different on different tables and felts and cues but that doesn't change the fact that it does work.
I Taught a friend right after PHJ came out. I taught him for 6 months and he became an A- player, now he's a 9 in the apa. Don't tell me there are no shortcuts. Have you been playing for 2 years and are a 9 in the APA?
I personally don't play in leagues and could care less to start, but you can't argue with those results.
This friend had bought a predator pool cue and stated that he couldn't use the aim pivot system with that cue. he said that this was because the predator cues have less deflection. I said let me see that cue and let him play with one of my Mcdermotts while I tried this predator. The system worked just fine with the predator. I played no differently with it than with my own cue. In fact I told my friend this and challenged him to try it again but to make sure that he stroked straight through the ball. It worked for him as well.
I ended up taking the predator and he kept the McDermott, but I was just using it as a break cue.
Yes to get to that level you have to have a good visual spatial ability and a lot of practice, but to say that having that knowledge or talking about it in this thread is just thearetical is ridiculous.
I want to say something else here as well. When I started playing seriously about 12 years ago, I watched a couple videos on basics and read I think one book, beyond that and what Efren told me that one time I have learned everything I have stated here on my own. Now mind you at one point I was playing 10-15 hours a day six days a week, but I discovered squirt and throw on my OWN through years of practice. I ended up learning the terms through various people and until coming to this site I didn't know the term squirt.
The point here is that people shouldn't have to go through years of playing hours a day to figure out these concepts. We as pool players should be willing to share our knowledge with them and help to bolster the sport. Hell, I don't blame people for not making pool bigger than it has been when people are so adverse to giving out knowledge or helping the poorer players. NO most pool players just suffice it to take their money until they don't want to play any more. Maybe it's easier for me to say that since I don't play for money, but come on, this attitude is what keeps pool from being huge. I mean it's an awesome game that's inexpensive and fun to play, especially when you can get better at it. There is no better feeling than breaking and running out and not letting your opponent even step up to the table.
Understanding the concepts is the important thing, not the terminology. We use squirt and throw but what we really mean is the tendency of the cue to push the CB off line when stroking through it off center and the tendency of two balls making contact with spin throwing off the line of intersection through extended contact. The terms used to describe those definitions don't matter as long as the person understands the concepts and the ramifications of their use. To truly play the game correctly though you NEED to understand those concepts.
To say no just play the game and learn through practice is asinine, you WON'T learn to play the game that way. You WON'T know where the CB is going to go even if you are able to pocket balls. Atleast not without playing for hours and hours a day and for years and years while paying serious attention to what is happening on the table.
