One of the things I hate the most when playing a match, is when I leave the cueball on the rail when I didn't have to. Either overhitting or underhitting the cueball will do this. Of course we all know that the cueball frozen on the rail (or close to frozen) limits your options to play position, and for most players, lessens their chances of making the shot. I really hate that feeling when I am staring at an easy rack, my confidence is soaring, and the cueball comes to a halt on the rail. Suddenly the rack becomes alot more tough, my confidence drops, and frustration sets in. There are two things that I have been practicing this week that have actually been helping me stay away from the rail, unless it's necessary. First, of course, I have been practicing all kinds of shots from the rail, which is probably the most important thing to do on this type of subject. Secondly, I have found that leaving yourself on the rail is usually attributed to a mental lapse, which comes from laziness for the most part. This mental lapse can be caused by playing alot of 9-ball...because 9-ball requires general area shape, people have a tendency to play only general area shape. For the majority of shots made, they don't try to visualize the exact path the cueball is going to be taking, and the exact spot it's going to hit on the rail, etc. I have found that actually taking an extra two or three seconds to visualize the cueball's path on an imaginary line, going into the rail (if that's the path you're taking), coming off, and then coming to a stop where I want it. By visualizing this, it's actually similar to programming your shooting arm to slightly adjust the speed you will strike the cueball with. When you really try to focus on this, and you practice like this, it really does help, or at least it does help for me.
