The (Modified) Corner Banking System
Here’s a very handy system to memorize. I can’t tell you the number of times I’ve used this method to either make a tough bank or kick myself out of a good safe. All you have to do is memorize the numbers down the rail: .33 .85 1.35 1.75 2.25 2.75 3.25 4.0 4.5 5.0 6.0. These numbers tell you where to aim using the diamonds on the long rail opposite from where you are standing. Ignore the opposite cushions and focus only on the diamonds. I call this the “modified” system because these numbers differ from most systems in publication. Why are my numbers different? I don’t know. These are emperical numbers taken from many practice sessions and they just seem to work for me. If you have trouble memorizing them, don’t fret, just get them tattooed on the inside of your left arm. For a more detailed discussion of this system, see my post on February 6, 2011.
Standard Banking System
This is the system I use for almost all of my banking needs. I can’t remember if I learned this system from Robert Byrne or Bob Jewett, but regardless, it’s very useful. At first you may need to use your cue stick to help visualize the lines, but after a good deal of practice, you’ll be able to see the lines in your head. Here’s how it works. First, draw a line from the object ball to the opposite rail (black line). From that point on the rail, draw a line to the pocket into which you want to sink the object ball (blue line). Draw another line (black line) from the object ball to the opposite pocket. At the intersection point of these two lines, draw a line to the opposite rail (red line). THAT point on the rail is where you want to send the object ball. Just hit with normal speed, and you will bank the ball successfully. Of course, this does require some practice.
