Theory of aiming in billiards
Billiards (billard, from the French bille - ball or fr. Billette, billart - stick) - the collective name of several board games with different rules, as well as a special table on which the game takes place.
A characteristic feature of all billiard games is the movement of balls with the help of a cue.
The room, specially equipped for playing billiards, - Billiard room.
Homeland of the billiard game is considered to be India or China.
Theory of sight
When carrying out strikes against the aim balls, it is necessary to choose the so-called true point of the sight.
Imagine a line passing through the middle of the pocket A to the center of the ball being played (see the figure). Point M (marked in red), located on the side of this ball, facing in the opposite direction from the pocket, and is the true aiming point, because it is in it that the contact of both balls is necessary in order for the object ball to be in the pocket. To facilitate the finding of this point, you can estimate the cue, that is, to kiss one ball in the pocket, and then to aim your "own" at the point found. But this is usually what novice players do. Experienced athletes at a glance unmistakably determine the aiming point and deliver accurate shots.
But for the correct playing of the ball to determine the point of sight is not enough. You still need to be able to correctly hit the ball. To do this, it is necessary to fully concentrate on the impending blow, trying to grasp the imaginary trajectories of the movement of "one's own" and "someone else's" and, after making 2-4 aiming strokes, confidently hit the cue at the appropriate point. Sometimes beginning players aim long, making up to 5-6 or more strokes with a cue, as a result, the blow is "wrong", the ball does not fall into the pocket. This is because the culmination moment before the impact are those short few seconds during which the player strains to maximum attention, and if the aiming time is tightened, then even before the impact comes the regular relaxation of the muscles, the sight and the impact is not effective.
First of all, we determine the intended path of the aiming ball into the pocket. Then determine the point of sight.
For this it is necessary:
- know (or measure) the diameter of the ball. (Standard balls in Russian billiards have a diameter of 60 and 68 mm., In American - 57 mm.);
- lay along the line of the intended path of the sighting ball 1/2 diameter in the direction opposite to the ordered pocket. This will be the point of sight.
All you have to do is aim at this point and hit the cue ball ...
Now let's look at all this in terms of practice.
In the aiming system, the most important thing is the choice of the strike line and the location of the cue ball. The accuracy of the stroke depends on the ability to see the blow line well. To practice this skill, there are many exercises, but the main thing is the exercise of the mirror. Another necessary exercise is to drive the cue ball into the pocket from different points on the table.
But first you need to learn how to look properly.
Eye work. Of the many ways of aiming and working the eyes (someone at the time of impact looks at the sighting ball, someone - at the point of hit, someone - in the cue ball), I propose the one that helps me to make an accurate blow.
At the beginning, before taking the counter, I see the place where the cue ball comes from above. To do this, in front of the aim ball, I mentally put an "imaginary" ball, which, together with the sight, would be strictly on the line passing through the middle of the pocket. This is not easy to learn at once, but if you specially train your eyes, then in time you will easily represent this auxiliary ball.
Then I imagine the corridor from the cue ball to the "imaginary" ball and in the middle of this corridor I mentally draw the line of impact. Vision of the corridor from the cue ball to the point of hit is especially helpful in carrying out strikes with various cuts (see next paragraph), and also when the cue ball is clogged, when it is necessary to present the corridor along which the cue ball bounces off from the sight ball into the pocket. After I have determined the hit point and the strike line, I stand in the rack and start to expose the cue on this line. In doing so, I do not move the cue forward and back, but just right-left to place the cue exactly along the line of impact.
After that I start to drive back and forth with one weight of cue, watching only the tip, which allows me to see if its movements coincide with the strike line.
I do 3-6 swings, then I stop the cue near the cue ball, I take a short pause and, without raising my head, let alone my shoulders, I look at the cue ball, trying to concentrate so that nothing distracts me. Then smoothly I take my hand back, I pause and smoothly "let go" cue his weight forward, as if imitating the movement of the sea wave that runs up to the pier.
In this case, I imagine in my mind that the cue will "reach" the sighting ball, and the cue ball does not seem to exist - at the moment of impact one should not lose concentration of sight at the place of hit.
Cutting. In this reception, the most important thing is the ability to see the cue ball and the line of impact. This helps the "imaginary" ball, mentally attached to the sighting. If it is difficult to imagine an "imaginary" ball, another method can be used: to divide the sighting ball by an imaginary line in the vertical direction to determine how much it needs to be cut off. Then mentally draw a corridor from the cue ball to the sighting ball so that the corridor line, for example, on the left, coincides with your vertical line on the target ball (when the aiming ball is cornered to the left).
The ability to see the corridor helps to determine the location of the cue ball.
Imagine that the task is not to hammer the sighting ball, but to direct the cue ball as if you were hammering it into the pocket. When such concentration of attention becomes a habit, your results will begin to improve.
It is necessary to make two pauses. One - at the moment of stopping the cue before the cue, after you are convinced that the cue is moving along one line, and the second - at the end of the swing before striking.
These pauses can be very short, almost invisible, but the "deeper" they are, the more controllable, I would even say, the blow is deliberate.
After the first pause, slide the cue back gently, as if you are pulling a string of bow. The body remains motionless. The right shoulder does not go up: if you involuntarily rise before the last swing, as a result you can lose the stroke line and deal an inaccurate blow.
At the moment of the second pause at the end of the last swing, try to make sure that the right shoulder is left in place. Shift of the shoulder is an inconspicuous but harmful error, because in this case the blow is not applied to the specified stroke line.
Learn to smoothly start the cue after the second pause, so that the movement starts from the brush, and not from the shoulder.
I want to draw your attention to the fact that when the second pause turns deep (1-2 seconds in duration), you will feel how you stand: in a calm state you stand firm and motionless. You need to be able to relieve tension, then you will quickly learn to make an accurate blow.
