I have seen some players bank better than they cut and in those players, this appears to be some kind of talent.
Now banking is something I am working on. I am no natural at it and it is certainly one of the weakest parts of my game. I do not lose any sleep over it, just do some banks each time I practice.
At first I was way off, then I got closer to making them, then got so the banks went in ocassionally. I do not want to clutter my head with systems either. My husband initially wanted me to learn the diamond system and I refused.
With practice, I look at the angle, try to decide if a little english is needed or not and just keep plugging away at it. Then, sometimes, the bank seems to have missed where it would have potted with a softer or harder hit, so just file that away to be practiced later.
The knowlege I have heard is: soft hits go wider,hard hits narrow the angle, ie narrows the angle, oe widens the angle. So with that, it is to the table and practice, practice.
If there is a 'woowoo' secret to this that will work with everyone I am not aware of it. I suspect the cure is the same as for the rest of pool: time on the table .
