Here's how I've always understood Bob Jewett's "two times fuller" method - works every time from every location (hit with some follow at medium speed).

i had forgotten the off angle correction

i corrected my original post
if the frozen balls were perpendicular to the rail it would have been correct
here is bob jewett explaining the two ball fuller system

I can't tell for sure, but you might not quite get it yet, Larry (correct me if I'm wrong).pj

When the cue ball and frozen ball point near the actual object ball (within 20-30 degrees?), bisecting the angle is close enough....
I don't believe the correct aim line ever bisects the angle (geometrically impossible)....

Bisecting the right angle line (not the angle) is the method whether or not the frozen balls are pointed directly at the rail next to the target pocket - that just makes the measurement easier (because the right angle line is the rail).

the balls are frozenCool shot, but can you shoot it without getting called for a foul? I doubt it.
Most people now play that as a legal shot if the cue ball is frozen to the object ball. There may be some leagues and tournaments that require you to do something nonsensical, like jack up 45 degrees, if you shoot it, but you can still shoot it.Cool shot, but can you shoot it without getting called for a foul? I doubt it.
Shooting at the upper left corner illustrates a couple of things about the Two Times Fuller method:...if the nine ball was in the upper left corner, there is no way to form a 90 degree angle between the frozen ball and the rail.
Shooting at the upper left corner illustrates a couple of things about the Two Times Fuller method:
1. Like Bob says, the smaller the angle the closer the midpoint of the right angle line gets to bisecting the angle.
2. Sometimes you have to visualize the right angle line out in space beyond the table's edge (so bisecting the angle might be easier).

over the years I have greatly benefited from the book"99Critical shots"
George Fels book was also helpful to me,as is Tom Wirth's book on one pocket.
Technically speaking it never quite splits the angle, but it comes very close on the smaller angles, as you can see.Excellent post. One can see that it splits the angle on 20-30 degree shots.
Only know what I've seen here, but there are lots of instances of pros thinking unrealistically (Mike Sigel famously didn't believe throw exists). Don't believe their "science" just because they're pros - check it out yourself.Thanks! Now if you know the book, can you think of other mistakes?
I think you must have set it up a little wrong. I tried it several times and always hit the long rail almost a half diamond above the pocket (where Bob's system predicts).I just got through making this shot the way he showed
I made it three times
i tried it at a bigger angle and missed
figrued it was me
