Sure they can. Knowing the mirror system and any good diamond system simplifies banking and kicking tremendously. As well CTE banking is the nuts if you are dedicated enough to learn CTE properly.
Jimmy Reid has been mentioned and he taught me the mirror system for one rail kicks. I modified it slightly to make it more comfortable for me to sight it from behind the cueball instead of having to walk around and sight from the object ball backwards to the CB.
That simplified one-rail kicks to the point where knowing it has made me money hundreds of times in hundreds of matches.
I even took it a step farther and figured out how to use it to calculate safeties and as a result my safety play went up a few balls because I started putting the object ball or cue ball exactly where it needed to be rather than guessing and under and over-hitting the ball to sell out.
Precision Aiming in Safety Play
Well, here is my point of view, John.
These systems are a 'rule of thumb'.....and damn good ones....
..that's why I applaud coaches and teachers....I worked for a golf pro when I was a kid....
....and became a fair golfer at a young age because of my boss.
But your game has to move on from those rules of thumb.
If you can make a bank or a kick in Oklahoma City....it won't be the same in New Orleans.
A long time ago, I was playing snooker on an Anniversary 5x10....in the spring....
...it was wet as hell and the table was playing very short...
...about the 4th game, I missed an easy snooker..... (long)...and I started laughing....
...my buddy, who had a piece of my action, asked me what the hell I was laughing at...
...I told him I had been adjusting on every shot for the extra short rails...but now I didn't
have to.....I had adjusted to the table, so now my FIRST aiming point was correct.
He said " That's why I like hanging around with you."
