I'm still trying to figure this out myself, but of course I've got theories and (of course) I'm prepared to ramble on (and on) about them.

There seem to be 3 main categories of bank shots. One is a nearly natural shot where you hit the object ball close to head on. Another type requires a very thin hit. The third category is made up of shots needing a nearly half-ball hit.

The first category can usually be seen pretty well. The second category is usually the realm of one-pocket players and I'm not very good at them. The third category is the one that's freaking me out.

In one of Burt's tapes he keeps saying "Cue tip, thru the center of the cue-ball, to the outside edge of the object ball." Translated into regular speech patterns this becomes "No English and a half-ball hit."

After watching Burt make 100 or so bank shots, all the while repeating his mantra "Cue tip, thru the center of the cue-ball, to the outside edge of the object ball" I went downstairs and hit some banks. Anything that looked like it would require a nearly half-ball hit I just shot with no english and exactly a half-ball hit. The damn balls just kept banking in. It almost looked like I knew what I was doing. I remember telling myself that I wish I could bank like this in real life.

I think what's happening is that by taking contact point and english out of the list of variables you're only left with shot speed. Of course shot speed plays a very big part in determining the angle the OB takes off the rail, so you've still got a lot of potential paths for the OB to take off that rail. Eliminating the options for english and contact point does not have to stop the shot from going - as long as the "proper" contact is somewhere near a half-ball hit, then an actual half-ball hit, with the proper speed, can still make the shot.

The voodoo part, for me, is how effortless my banks have become. I put the OB on the footspot, the cue-ball on the head spot, and whack a half-ball hit at the right side of the OB. The OB banks back up into the left corner. I set up the same shot, but with the cue-ball two feet to the right this time, and a half-ball hit still puts the damn OB into the same corner. Obviously I'm varying my speed a lot between these two shots, since the english and the contact points are constant, but I'm completely unaware of making this adjustment.

A shot I've always had trouble with is this: Put the OB near the side rail, down-table a bit from the side pocket, and put the CB near the head spot. Try to cross over the OB and bank it into the opposite corner. I was about 25% on these shots until I started hitting them half-ball with no english. I'm probably about 70% on them now. I'm starting to look like a one-pocket player or something. Damndest thing I ever saw.

I know that a half-ball hit can produce the most throw, and that the collision speed also effects the amount of throw. Balls hit hard into a rail rebound at a greater angle than balls hit softly into a rail. So a softer half-ball hit will throw a lot, resulting in an apparent fuller hit, and open up the rebound angle, while a harder hit will result in an apparent thinner hit and a more closed rebound angle. You get an awful lot of leeway on a half-ball hit just by varying the speed.

Burt said himself that he didn't know why it worked as well as it did. I sure don't know either but it allows me to bank shots that I've never been comfortable with before. In the words of C.J. Wiley - "Hey, it works for me." And in the words of someone else - "If it ain't broke, don't fix it."
