There are

A w a r n i n g on this d r a w s h o t : If y o u
d o n ' t get e n o u g h d r a w o n y o u r f i r s t few
s h o t s , y o u m a y hit
t h e b a l l o n t h e far

to drive the ball
straight toward you,
making
the
shot
increasingly
difficult. A g o o d g o a l is
to drive the ball
toward pocket B. If
the ball goes along
that
line,
the
required d r a w will
remain
reasonable.
In p r a c t i c e . 1 f o u n d
this s e c o n d f o r m o f
the shot e a s i e r t h a n
the first.
In D i a g r a m 2 is an
exercise using the
cushions. The set-up
is fairly c r i t i c a l : T h e
object ball is one
d i a m o n d from the
long rail and the cue
stick p a s s e s o v e r t h e
m i d d l e of the rail
section at the diamond as shown.
You will p r o b a bly play b e t w e e n
these extremes, no
matter what your
g a m e is. T h e p l a n
this m o n t h is to
work on the closeposition
part
of
your game.
In D i a g r a m 1 are
two similar drills
to w o r k on control of both speed and
d i r e c t i o n . I n S h o t A , t h e cue ball a n d the
o b j e c t ball a l w a y s r e t u r n t o t h e s p o t s
m a r k e d — y o u m a y a s well m a r k t h e m o n
the cloth with paper reinforcement
" d o n u t s " o r c h a l k . T h e s e c o n d o b j e c t ball
T r y to d r i v e it as s t r a i g h t as p o s s i b l e
toward the pocket labeled A.
S h o t B in D i a g r a m 1 is similar, but the
o b j e c t ball starts m o r e t o w a r d y o u s o that
y o u will n e e d t o d r a w t h e c u e ball t o m a k e
c o n t a c t . T h e g o a l i s to g e t at least five (or
10) soft c o n t a c t s b e f o r e t h e s h o t b e c o m e s
t o o difficult.
If t h a t ' s t o o eas y, tr y for 10. R e m e m b e r
not t o c o u n t a n y s h o t t h a t e i t h e r d o e s n ' t
touch the second ball, or leaves it more
than a b a l l ' s d i a m e t e r f r o m t h e c u e b a l l .
It is useful to h a v e a specific g o a l for the
d i r e c t i o n y o u a r e d r i v i n g t h e s e c o n d ball.
T h e distance from
t h e c u e ball to the
o b j e c t ball is up to
y o u . If it is c l o s e r ,
t h e s h o t is e a s i e r , so
begin there. As you
develop more control, try m o v i n g t h e
c u e ball b a c k t o w a r d
the
cushion,
but
a l w a y s w i t h t h e c u e s t i c k p a s s i n g o v e r the
second diamond.
T h e g o a l h e r e is to s e n d t h e c u e b a l l in
turn to l o c a t i o n s A t h r o u g h J. S h o t A is a
plain draw shot, and this shot is very
t o u g h if t h e c l o t h is s t i c k y or t h e c u e ball
is h e a v i e r t h a n t h e object b a l l . It will a l s o
b e c o m e h a r d e r t h e farther b a c k t h e c u e
ball s t a r t s .
With practice y o u should be able to leave
the c u e b a l l w i t h i n a ball of the target at
least o n e i n t h r e e ,
but at first j u s t try to
hit the target. Shots
A and B are direct,
but C and D n e e d to
be played w i t h one
cushion.
For
the
shots u p the s e c o n d
side rail, t h e r e are
t w o w a y s to get to
t h e m — go o n e rail
and then t w o rails.
For extra c r e d i t , try
to get the c u e ball
out to the side p o c k et on y o u r s i d e of the
table. Is it p o s s i b l e ?
N e x t , see h o w the
s h o t s c h a n g e if the
c u e ball i s m o v e d

shots b e c o m e easier and which harder?

O n e o f the most a m a z i n g talents o n any

billiards and p o o l His artistic shots are the
stuff of legend, and now they are available
online.

without putting s o m e right spin on the ball.
years of practice, and probably m o r e than
one take.
Given the shot a n d m a s s e lines a n d the
right side spin, h o w d o e s the illustrated shot

line. T h e m a s s e line accelerates the cue ball
toward the first rail a n d m a k e s it curve. You
N o t e that at s o m e point in the second part
of the path — b e t w e e n the first and second
c u s h i o n s — the m a s s e spin runs out. and the
cue ball begins to roll smoothly on the cloth
without slipping. After that point, the cue
ball's path will be a straight
line.

an e x p l a n a t i o n of what you
saw.
O n c e the ball follows the

r e m a i n i n g right spin t a k e s
w h e n the ball contacts the end
c u s h i o n and t h e c u e ball
c o m e s back to the side rail for
a fourth
cushion
contact
before hitting the two object
balls. S i m p l e .
D i a g r a m 1 s h o w s the
first shot on the video; a
m a s s e shot I h a d never seen
before. At first glance it
l o o k s like it m i g h t be
impossible, but the action is
actually straightforward. It
is a four-cushion shot. If
you s h o w the position to
s o m e o n e and n a m e the hits
in o r d e r — side rail, side
rail, e n d rail, side rail, both
balls — it c o u l d be a long
time before he guesses the
path.
When
shooting
masse

direction,

achieve a particular path. For e x a m p l e , in
D i a g r a m I, the initial direction of the shot is
along the "shot line." T h e stick is elevated
and p l a y e d with right draw. This produces
b o t h right side spin and a tendency to curve.
We can assign a direction to this tendency to
curve by i m a g i n i n g (or causing) the cue ball
to run straight into an object ball, and then
seeing w h i c h w a y the c u e ball m o v e s . F o r
this shot, the " m a s s e l i n e " s h o w s which way

is s o m e right side spin, which is a necessary

can think of the m a s s e acting like gravity
with the m a s s e line saying "this w ay d o w n . "
T h e ball hits the first c u s h i o n and it
b o u n c e s , m o r e or less, straight back with the
right side spin h e l p i n g to bring the ball back
down the table. As the cue ball c o m e s off the
rail, the m a s s e line is a l m o s t u n c h a n g e d , so
the ball again w a n t s to "fall" b a c k to that
same cushion and the path curves again. In
theory, if there w e r e e n o u g h m a s s e on the
ball, it c o u l d be m a d e to return to that s a m e
long cushion. In S a y g i n e r ' s shot, there is just
e n o u g h m a s s e to bring the c u e ball to a path
that grazes the other long cushion at a fairly
shallow angle. H o w does he do that? By feel.
S a y g i n e r ' s third shot is
s h o w n in D i a g r a m 2. a n d
might be called a draw/follow
m a s s e . T h e shot line is more
or less directly into the end
cushion. T h e m a s s e line is
toward the c u s h i o n and back
toward the second object ball,
a n d there is s o m e left side
spin. T h e cue ball is shot hard
e n o u g h that it mostly slides
off the end cushion and to the
first object ball. In the video,
you can see that there are at
least t w o different paths that
will w o r k , as the different
angles w e r e shot on t w o different takes. T h e shot that
starts and e n d s the clip has the
cue ball going first to the e n d
c u s h i o n , then twice on the
long cushion before it hits the
first object bull, then three big hops on the
long cushion a n d then a straight path to a last
contact on the long cushion just before the
object ball for a total of seven cushion contacts.
T h e shot is not hard to understand, given
the shot line a n d the m a s s e line. T h e masse
will tend to k e e p the cue ball on the long
cushion between the e n d rail and the first
ball, so the aim d o e s n ' t have to be perfect.
As long as there is still s o m e m a s s e spin left
on the cue ball after it hits the first object
ball, it should return to the long cushion
s o m e more. In the shot on the video, the cue
ball h a p p e n s to be about half a ball off the
cushion w h e n it hits the first object ball so
the r e m a i n i n g h o p s are large and obvious.
D u r i n g t h o s e h o p s , t h e r e m a i n i n g left
English on the cue ball helps to b r i n g it
d o w n the table to the s e c o n d object ball. T h e
m a s s e gives out a b o u t t w o
d i a m o n d s from the second
ball, a n d the last part of
the p a t h is a straight line to
the score.
D i a g r a m 3 shows the
fifth shot Sayginer does
on the v i d e o . It's a fairly
standard shot in concept,
but the action is not standard. T h e shot line is up
the table, and the m a s s e
a c t i o n i s m o r e o r less
straight b a c k from the shot
line. I think there is a little
right English on the cue
ball. If so, the shot line
a n d m a s s e line c a n 't be directly opposite —
that is only true for p u r e m a s s e d r a w without
b e n d i n g to the side.
T h e cue ball hits the first object ball thinly
a n d travels forward along the cushion. It gets
four cu s h io n contacts as the masse'fights to
k e e p returning it to the rail and speeds it
toward the s e c o n d object ball. T h e cue ball
gets a total of 11 contacts on the long cush-
ion before hitting the end rail and c o m i n g
straight off the end rail to the second object
ball.
O n e r e m a r k a b l e feature of t h e shot is that
the second object ball is barely m o r e than a
ball off the cushion. As the cue ball passes
between it a n d the rail, there looks to be less
than a quarter-inch of clearance. T h e principle that m a k e s it possible to pass through
such a small g a p is " d y i n g b o u n c e . " Imagine
dropping a tennis ball. If the first b o u n c e is a
foot, the second m a y be half a foot a n d the
third a quarter foot, and so on. After a few
b o u n c e s , all the subsequent b o u n c e s are
quite small. T h e m a s s e spin is again acting
like gravity to cause the b o u n c e s , a n d t h e
imperfect elasticity of the c u s h i o n c a u s e s the
d y i n g out of the b o u n c e s of the cue ball.
On the shot on the v i d e o , y o u can see that
the first b o u n c e is a b o u t
the d i a m e t e r of the c u e
tip, a n d on each s u b s e quent b o u n c e the cue ball
leaves t h e c u s h i o n less
and less. Since there are
nine
bounces
before
threading the g a p , the cue
ball is g u a r a n t e e d to be
very close to the c u s h i o n
at that instant.
T h e r e is a similar shot
by t h e great J a p a n e s e pool
trick-shot artist Yoshikazu
K i m u r a in w h i c h he h a s a
line of balls near the c u s h ion, he m a s s e s the c u e ball
off an object ball, a n d the cue ball p a s s e s
b e t w e e n the line of balls and the c u s h i o n , not
touching any of t h e m . After the shot, he
demonstrates that there is less t h a n a p l a y i n g
card's thickness of m a r g i n for the c u e ball to
pass. On YouTube, search for " K i m u r a p o o l
s h o t s " to see s o m e o t h e r great shots.

The controversy has existed since the early 1900s, and continues to "vex.'
T h e r e is
a controversy in the
billiard world that has b e e n
simmering
and
sometimes
boiling over for the last hundred years. You would think
that in all that time, s o m e o n e
w o u l d h a v e been able to get to
the b o t t o m of the matter and
shut up the idiots on the other
side,
but the controversy
r e m a i n s : Is it possible to transfer sidespin from the cue ball to
the object ball?
lot like c a r o m billiards but is
p l a y e d with small balls on a 6by- 12-foot table with pockets. In
his 1923 b o o k , " H o w to Play
Billiards," Tom N e w m a n , w h o
w a s a six-time world c h a m p i o n ,
firmly staked out a practical,
middle-of-the-road position:
"[...] Last, and least, I p r o p o s e
to touch u p o n the vexed question
o f t h e t r a n s m i s s i o n o f side.
E n o u g h has been written to fill a
b o o k bigger than this, simply to
p r o v e that a side-laden cue-ball
c a n or c a n n o t transmit side to the
object-ball. I am not disposed to
argue about it, but if a n y o n e can
s h o w me h o w to transmit an
effective a m o u n t of side from the
cue-ball to the object-ball, I shall
be very m u c h indebted to h i m : it
will help me to solve m a n y little
p r o b l e m s [...] Please m a r k my
w o r d s carefully, I do not wish for
' p r o o f that side can or c a n n o t be
transmitted. I want to s e e such
m e a s u r e of effective transmission of side as m a y be of real
playing value. Until I see this, I
shall not bother about the transmission of side w h e n playing
billiards."
I t h i n k t h e continuing confusion is d u e to the fact that if the
effect exists, it is w e a k . You
can shoot the cue ball with
heavy sidespin directly into an
object ball and the cue ball will
sit a n d spin like a top, so no
o n e will deny that the cue stick
can p u t sidespin on the cue
ball. You c a n n o t , h o w e v e r ,
m a k e an object ball spin similarly. B u t can you m a k e it spin
at ail?
28
T h e earliest reference I've
found for the question is also
o n e of the easiest early billiard
b o o k s . " D a l y ' s Billiard B o o k "
w a s first published in 1913, but
is n o w widely available as a
D o v e r reprint. In it, Maurice
Daly describes a class of shots
in w h i c h an object ball is driven m o r e or less straight into a
cushion and is banked with
precision b a c k to where it started. (This is a standard shot at
simple
carom
billiards.)
M a u r i c e c o m m e n t s : "In this
shot ( a n d its variations are
n u m e r o u s in close play near
the e n d rail) o n e must pay strict
attention to the English on the
cue hall. That imparted to the driven object
ball affects t h e course of the latter on its
return from the cushion. This driven ball may
be "thrown' o n e side or the other as m u c h as
three inches."
cue ball is not, to any appreciable degree,
transferred to an object ball, not e n o u g h to
'throw' the object ball off a true angle from
the cushion. T h e writer [Harris] is convinced
he is right [...]"
Slightly later, we find t w o prop o n e n t s o f the p h e n o m e n o n
claiming to s h o w such shots.
T h e t w o authors were Walter
Lindrum and Willie Smith.
L i n d r u m w a s the best English

who
ever
played, and arguably the best c u e m a n of all

other three players a head start of about 30
percent in w e e k s - l o n g m a t c h e s and he still
won. Smith w a s twice a world c h a m p i o n .
This s e e m s like a pretty clear statement, but
the editor (W.W. Harris), had said earlier in
the book: "Mr. C . C . Curtis, of N e w York, has
m a d e many interesting experiments with billiard balls, and contends that the spin of the
It would have been helpful if the author a n d

England during the 1930s. T h e g a m e being

D i a g r a m 1 and D i a g r a m 2 are from
L i n d r u m ' s 1930 b o o k "Billiards." T h e goal is
to scratch off the black ball from behind the
line. T h e sub-goal is to control the return
point of the black ball. L i n d r u m claims that
BD • APRIL 2007
N e w m a n ' s approach is quite
reasonable: He is asking for specific e x a m p l e s that will help his
g a m e , a n d is w i t h h o l d i n g his
j u d g m e n t on the matter until
then.
in D i a g r a m 1, right E n g l i s h puts e n o u g h left
on the black ball to k e e p it on the left side of
the table. In D i a g r a m 2, he h a s c h a n g e d to
left English, w h i c h h a s w o r k e d the red w a y
over to the right side of the table.
I n d i s c u s s i n g t h e shot, L i n d r u m a l s o
laments about t h e forests wasted in printing
opinions on the matter, saying, "I have yet to
meet a m a n w h o c a n play any better for all
this spilling of ink."
He c o n t i n u e s : " B u t get away from theory,
put the balls on the table, and I will p r o v e to
you that the influence of side on the cue-ball
is transmitted to the object-ball to such an
extent that you c a n n o t play billiards without
allowing for it. [You m a y call w h a t h a p p e n s
in the d i a g r a m s whatever you want] but
please give me my point that t h e effect of the
side is transmitted to an extent, w h i c h could
scarcely be surpassed if you were putting
side on the object-ball with your cue."
T h a t 's a b o u t as clear as you can get. But do
his e x a m p l e s really s h o w that the object ball
has spin that affects its angle off the c u s h i o n ?
Smith, in his 1934 b o o k "Billiards in Easy
Stages," s h o w s the shot i n D i a g r a m 3 .
Again, the goal is to scratch off the black ball
and to control the path of the black ball off
the cushion. You can try it yourself on a pool
table with the object ball about t w o balls off
the e n d cushion and the c u e ball n e a r the side
pocket. Adjust the cue-ball position so that a
half-ball hit with follow and m e d i u m speed is
a g u a r a n t e e d scratch. Smith says about the
shot: " T h e r e is no stroke on the table w h i c h
proves so clearly that side can be transmitted.
Playing it half-ball, without side, the [black
ball] will c o m e down the centre of the table.
But, if the [other object ball] should happen
to lie in its course, it is quite an easy matter
to g u i d e the [black ball] past that ball on
either side. If you want the [black ball] on the
right-hand side of the table, use left-hand
side on the cue-ball, and vice versa to bring
the [black] ball to the left-hand side of the
table."
T h e big gun of British billiards writers,
R i s o Levi, fired against these t w o c h a m p i o n s .
To Levi, w h o h a s the distinction of having
written the most w o r d s on billiards of any
author, there w a s no such thing as transmitted side. A n y effect that w a s observed could
be explained by the normal curving of the
cue ball due to the sidespin, w h i c h is easily
d e m o n s t r a t e d and explained.
In his 1935 b o o k , "Billiards for All T i m e , "
he said: "I have written so m u c h in the past
on the question of transmitted side — I was
the first to treat the subject at all exhaustively — that I thought I h a d done with it forever. Willie Smith has, however, revived the
question in his latest book, "Billiards in E a s y
Stages," and though I h a v e a great liking for
him as a m a n and a t r e m e n d o u s admiration
for h i m as a billiards player, I feel bound to
pick up the gauntlet, which he has again
thrown down."
T h e book is only a small one, and, of its 91
pages, 32 are full-page diagrams. It is, h o w ever, a very readable little v o l u m e , but five
different ridiculous statements concerning
transmitted side m a r it.
"[...] W h e n y o u play a slow or m e d i u m p a c e stroke with side y o u give the object
ball a different line of travel from w h a t it
w o u l d take in a stroke p l a y e d w i t h o u t side,
but this is simply b e c a u s e side pulls the cue
hall out of the line of aim before contact is
m a d e with the object ball. T h e object ball is
taken t h i n n e r or fuller than w o u l d have b e e n
the c a s e with a plain-ball stroke. T h a t is all.
It is p a s s i n g strange to me that a great c u e m a n like S m i t h c a n n o t realize this, but
s o m e t i m e s w h e n a m a n gets t h o r o u g h l y
o b s e s s e d with a certain idea, he c a n n o t see
w o o d for trees."
Frankly, I d o n 't think I w o u l d h a v e liked

Let's Twist Again
Putting to rest a controversy that has existed since the early 1900s.
Last m o n t h I w e n t over s o m e ancient
history of this controversial q u e s t i o n : C a n
sidespin be transferred from the c u e ball to
the object ball? E v e n t h o u g h this p o i n t has
been d e b a t e d for m o r e t h a n 100 years, there
still s e e m s to be no general a g r e e m e n t . I
hope that 2 0 0 7 will finally e n d the d e b a t e .
First, l e t ' s look at the m e c h a n i s m that
purports to transfer sidespin from one ball
to another. In D i a g r a m 1 is a collision
b e t w e e n the c u e ball and an object ball.
D u r i n g the collision, there are t w o k i n d s of
forces. F o r c e s have to act at the c o n t a c t
point, since that is the only w a y the cue ball
can influence the object ball. T h e two
forces act in t w o separate directions.
T h e first is the usual force that acts to
p u s h t h e object ball a w a y from the cue ball.
It's called the " n o r m a l " force by p h y s i c i s t s ,
but this is not the n o r m a l " n o r m a l . " In this
case, n o r m a l m e a n s p e r p e n d i c u l a r to the
surfaces of t h e balls or along the line j o i n ing their centers at the m o m e n t of impact.
The force is quite high,
and very short — p e r h a p s
1,000 p o u n d s of force for
2 0 0 millionths of a second.
If that w e r e the only
force d u r i n g the collision,
playing pool would be
m u c h simpler than it is.
For better or w o r s e , there
m a y a l s o be a tangential
force. T h i s acts a l o n g the
tangent line b e t w e e n the
balls at the instant of c o n tact, and it's a result of the
surface of t h e cue ball r u b bing a c r o s s t h e object ball.
Since the t w o balls are not
perfectly slippery, there
will be s o m e friction a n d ,
consequently, s o m e force
at the e d g e of the object
ball.
T h e tangential force is
fairly c o m p l i c a t e d , and can
take quite a w h i l e to c o m p l e t e l y u n d e r s t a n d . In a
future article, I'll show y o u
s o m e related shots that I
only learned in the past
m o n t h , after 40 years of
p l a y i n g the g a m e .
A
28
first
complication
BD-MAY20Q7
is
h o w the surface of the
cue ball c o m e s to be
m o v i n g on t h e surface of
the object ball. If the cue
ball is not s p i n n i n g at all
but is cutting the object
ball, its surface will be
m o v i n g relative t o the
object ball at the point of
contact, and the friction
will tend to d r a g the surface of t h e object ball in
the direction t h e cue ball
e n d s up m o v i n g as it
leaves the collision.
A s e c o n d w a y to have the surface of the
cue ball m o v i n g relative to the object ball is
for the c u e ball to be s p i n n i n g . T h e r e are
several c a s e s t o r this. T h e cue ball m i g h t hit
the object bail full, but with sidespin. It
could be cutting the object ball with inside
English (left sidespin for a cut to the left),
w h i c h w o u l d increase the relative m o t i o n
c o m p a r e d t o the c a s e
a b o v e with no spin on
the c u e ball. Or, there
might
be
outside
E n g l i s h on the cue ball,
which could perfectly
cancel the friction d u e
to the m o t i o n of the c u e
ball a c r o s s the object
ball, or it m i g h t even be
e n o u g h t o r e v e r s e the
direction of the r u b on
the surface of the object
ball.
To c o m p l i c a t e things a
little m o r e , you a l s o h a v e to c o n s i d e r any
follow or d r a w that the c u e ball m i g h t have.
T h e first effect of this r u b b i n g s i d e w a y s
of the c u e ball on the object ball is throw. If
there is throw, the object ball will not travel a w a y from the collision along t h e line
j o i n i n g the centers of t h e t w o balls at the
instant of t h e collision, but i n s t e a d will
m o v e at an a n g l e of up to six
degrees for r e a s o n a b l y c o m m o n c o n d i t i o n s . (If you have
brand new, w a x e d balls, you
likely w o n ' t see that m u c h
throw, but y o u will see some.)
T h r o w is not u n e x p e c t e d if
you agree that the cue ball can
r u b s i d e w a y s on the object
ball. If t h e r e is a rub to the
right, there pretty m u c h has to
be
some
corresponding
m o t i o n to the right. In n o r m a l
collisions, the " n o r m a l " force
is m u c h larger than the r u b b i n g or tangential force, so
while there is throw, it's small
e n o u g h that the careless player m i g h t not notice it.
Conversely, if you observe
throw, there m u s t hav e b e e n
s o m e r u b to the side of the
surface of t h e c u e ball on the
object ball. T h e t w o are perfectly tied together. You cannot have one without the
other. If you see no throw,
there w a s no rub.
W h a t is not so o b v i o u s is a
p o i n t t h a t e s c a p e d m e for
a b o u t 35 y e a r s . If there is
throw, t h e r e m u s t a l s o b e

the s a m e s i d e w a y s force of the c u e ball
r u b b i n g o n the object b a l l . You c a n 't r u b
s i d e w a y s on the c u e ball and not m a k e it
spin. P h y s i c s can tell us h o w m a n y R P M of
sidespin we will hav e if there is one d e g r e e
of t h r o w (for a particular s p e e d ) , b u t that is
not as interesting as the f o l l o w i n g m e a surement.
Spot t w o object balls on the foot spot, as
s h o w n in D i a g r a m 2. P u t a third object ball
near t h e m so it forms a line with a spot
about t w o d i a m o n d s from a far c o r n e r
p o c k e t , s h o w n a s spot X . Place t h e c u e ball
a l o n g that s a m e line, so that you are shooting the third ball straight into t h e s e c o n d
ball. T h e ball on the spot will be driven to
the end rail, but not the m i d d l e of t h e end
rail. It will be t h r o w n to the right, thanks to
the s e c o n d ball r u b b i n g across its surface.
S h o o t the shot a few t i m e s until you get the
speed right to d r i v e the ball to the h e a d rail
and b a c k to the foot rail with a little
b o u n c e . Take several shots t o m e a s u r e
w h e r e the ball hits on the h e a d rail and
w h e r e it r e t u r n s to the foot rail.
W h e n 1 did the test, and c o n v e r t e d the distances to a n g l e s , it tunned out that the object
ball initially threw off the centerline by 5.1
d e g r e e s for t h e c o n d i t i o n s I h a d . T h e
r e b o u n d a n g l e off t h e far c u s h i o n w o u l d be
equal to that, but I m e a s u r e d it as 10.3
d e g r e e s . T h e angle out w a s t w i c e the angle
in! As it turns o u t , this angle c a u s e s the
b a n k e d ball to go into a c o r n e r p o c k e t at the
foot of t h e table. Spin has clearly b e e n
transferred to the object ball, but can it be
done from the cue ball?
S o m e r e a d e r s will think i t 's pointless t o
set up a test with the c u e b a l l , since the
object balls are e x p e c t e d to h a v e the s a m e
reactions with e a c h other as they do with
the c u e ball, but let's be c o m p l e t e and figure out a w a y to test w i t h the c u e ball transferring side directly to t h e object ball.
A first test h a s already b e e n d o n e . In
D e c e m b e r 2 0 0 2 , 1 p r o p o s e d a test to see if
sidespin on the cue ball c o u l d t h r o w the
object b a l l . In April 2 0 0 3 , I r e p o r t e d the
results as d o n e by you r e a d e r s . T h e largest
a m o u n t o f t h r o w r e p o r t e d w a s slightly
m o r e than five d e g r e e s . T h e test h a p p e n e d
to a l s o be set up from the spot, and the
object ball h a p p e n e d to a l s o go in the corner p o c k e t w h e n i t c a m e b a c k d o w n the
table.
But that's not s o m e t h i n g t h a t 's likely to
m a k e you m o n e y . H e r e 's a proposition shot
that m i g h t . P u t an object ball on the foot
spot a n d , with t h e cue ball in h a n d , b a n k the
object ball back to the foot p o c k e t hitting it
full and w i t h o u t side spin. Find the spot on
the h e a d rail that you h a v e to hit to m a k e
the ball. P u t a b l o c k e r ball at that exact
location, as in D i a g r a m 3. N o w , bet that
you can b a n k a ball off the s p o t , back to the
foot p o c k e t a n d land either to t h e left or the
right of the blocker ball. Of c o u r s e , the only
way this can be d o n e is by getting s o m e
sidespin on the object ball. I h o p e y o u
k n o w w h i c h side to use for each side of the
blocker.
W h y d o s o m a n y p e o p l e get this stuff
w r o n g ? I think the m a i n p r o b l e m is that the
effect of the transferred sidespin is fairly
s m a l l , and it's only really visible on b a n k
shots. M o s t p e o p l e k n o w b a n k s s o poorly
that t h e y a r e w i l l i n g to w r i t e off five
d e g r e e s of u n e x p e c t e d increase in b a n k i n g
angle to their o w n erratic stroke or a funny
rail. A n o t h e r factor is that you d o n 't a l w a y s
see that m u c h twist (that's w h a t b a n k e r s
call transferred s i d e s p i n ) . If the balls are
w o r n or dirty, you will see q u i t e a bit m o r e
t h r o w and twist than if the balls are n e w
and polished or w a x e d .
Is five d e g r e e s important in p l a y ? In the
length of the table, t h a t 's a l m o s t nine inche s , or well o v e r half a d i a m o n d . If y o u are
g o i n g to shoot long b a n k s , y o u h a v e to
c o m p e n s a t e for this effect. Shor t b a n k s t o o ,
since 4.5 inches (half of the long w a y for
the shorter travel to the p o c k e t ) is about the
width of the p o c k e t .
