Take your tablet !
A new multimedia application for iPad ( and perhaps, Androïd later ) will arrive in october.
It purpose a lot of interactive possibilities:

• diagrams
• 3D views
• videos with multiple angles of view
• explanation and description about the shoot to play

This application is realized by Daniel Zimmermann

With it, we can improve our training level on a billiard table.
Look at this demonstration (source CAROMBOOKS.COM):

To make a shot, with a good direction of the played ball on the billiard table, U can apply some parameters before to play the shot



On the website of Laurent GUENET, I find a series of questions/answers usefull to do this
 

QUESTIONS

A – How do we get a natural shot of 45° ?
B – For a natural shot how do you adjust the speed of the player ball ?
C – For a one cushion natural shot what is the parameter steering the ball 1 ?
D – With a direct backspin dropshot, opened angle, what is the parameter steering the ball 1 ?
E – With a backspin, acute angle, what is the use of the quantity of ball ?
F – With a backspin one cushion what is the use of english ?
G –With a backspin, acute angle, what is the parameter influencing the speed of the ball 1 ?
H –On a natural follow through what is the parameter steering the ball 1 ?
I - On a one cushion follow through what is the parameter influencing the speed of the ball 1 ?
J – On a direct right angle what is the use of the quantity of ball ?
K – On the compensation point, one for two, what is the use of english ?
L – On the compensation point, one for two, what is the use of the height of attack ?
M – On the compensation point, one for two, when the ball 2 is on the good way, the ball 1 get a good way too buy does not come as far as the ball 3, how do you manage to correct the shot ?
N – With a piqué, what is the parameter influencing the distance covered by the ball 2 ?
O – With a piqué, what parameters are influencing the backspin of the ball 1 ?
P – On the backspin, acute angle, what parameters are influencing the distance of the backspin of ball 1 ?

ANSWERS

A - half ball (+ or -) and heading shot in the ball

B - with the quantity of ball
by taking less than half a ball the ball is rolling faster and further and is less deflected on the side
by taking more than half a ball  the ball is rolling slower and not as far and is less deflected on the side

C - the english
The amount of english could be 1 to 2,5 to obtain a deflection of 1 to 2,5 spaces between two spots (on the side of the table), this for a one cushion shot in the width.

D - the height of the attack
A drop shot is obtained by taking full ball, it is the height of the attack which is steering the ball 1

E - it manages the direction of ball 1

F - it manages the direction of ball 1

G - the height of the attack

H - the quantity

I - the height of the attack

J - to the speed of ball 1

K -  to the speed of ball 1

L - to the direction of ball 1

M - you need to vary the speed of ball 1, therefore you must modify the english and the height of the attack to adjust the direction of ball 1

N - the tilt of the cue
More vertical, less is the distance running by ball 2
Less vertical, more distance runned by ball 2

O - the height of the attack and the strength of the shot
Lowering the attack and/or higher stength is resulting in more backspin for ball 1  

P - the height of the attack and the strength
Lowering the attack and/or higher stength is resulting in more backspin for ball 1

Here is a video of free game level National 1 played at Dijon-France and recorded by JdBillard
U can watch GOUGELIN vs FERREIRA (300 pts in five innings )

Watch the big serie of 268 pts made after the 17th minute

I find on TouTube this interesting video where Paul COUESPELL teaches with pedagogy how to play the rail nurse serie:

• the typical points and their realisation
• the traps to avoid

In this animation you could see :

• that we hit the object ball twice as big as the aimed quantity
• where is the hiting point compared with the aim

To change animation's parameters :

• aiming : click, move and click the little gray circle
• distance between balls 1 and 2 : move the cursor key

The red ball will be propeled according to the axis connecting its center to the center of ball 1 before the hit.

The more the balls are close, the more the touched quantity of the red ball will be important, independently of the aim.


On those two sketches, with a distance of 2 centimeters between balls, we see that aiming 1/2 or 3/4 of ball 2 don't change the positions of the 2 balls after the hit.

• Aiming a quantity of 1/2 ball

• Aiming a quantity of 3/4 ball

To make easier the shot it is better to reduce the aimed quantity of ball 2

Emile WAFFLARD was world champion at balkline 71/2 and as won 10 europeans title ( balkline 71/2, 47/1, 47/2 and cushion )

He teach billiard at Frédéric Caudron, Eddy Leppens and Peter De Backer.

On this YouTube link, there are some videos where he explains the balkline conception.
