A little practice with the cue without a ball is useful to familiarise a beginner with the necessary action, that is the horizontal backward and forward motion; a slow withdrawal followed by a faster forward stroke. When this is attained practice with one ball should be commenced. It is of the highest importance; for by means of it alone can the rare qualification of a true delivery of cue be acquired. And this applies not merely to beginners, but to persons who are out of practice, for the commonest of all faults, and the secret of most failures to score, is that the player’s ball is not truly struck. It may seem strange, but it is nevertheless true, that many persons who play what is held to be a fair game cannot truly strike a ball.

Let us then suppose a ball placed on the spot on the centre of the baulk circle, and that the player has assumed a suitable attitude in order to play up the table over the billiard spot. The tip of his cue should be about half an inch from the centre of the ball, and the axis of the cue should be as nearly as possible parallel with the surface of the table, and in the same vertical plane as its central line, because the path travelled by a ball truly struck in the centre is, till after impact with a cushion or with another ball, invariably a prolongation of the axis of the cue. Having aimed carefully over the spot, he should draw the cue slowly back three or four inches and then bring it forward, giving the ball a smart tap, in contradistinction to a push, in the centre; the strength of the stroke to be such that the ball shall return into baulk. If ball, table, and stroke are true, the path travelled will lie precisely over all the spots in the central line; and after impact with the top cushion the ball will return to baulk by the same route. Herein is manifest the excellence of this stroke for practice; because if the ball be struck either right or left of the centre, it will return to the right or left of the central longitudinal line of the table. The nearer the return path is to that line the better the stroke, and the further it is from it the worse; so that an infallible measure of the truth or accuracy of hitting the ball is supplied by the result. It is impossible to overstate the value of this test, and by the time that a person can play this stroke up and down the table with varying strength and fair accuracy he has gone far towards mastering the first step at billiards. To secure striking the ball in the centre, as soon as aim is taken the player should fix his eyes on the ball and try to the best of his ability to deliver the cue truly and as horizontally as possible so that the tip does not see-saw up and down. The tap on the centre of the ball should be sharp and clean, the cue being permitted to follow it for a few inches; less when the stroke is soft, and more when it is hard.

It may probably appear in course of practice that the striker has a tendency to hit the ball either right or left of the centre; he should correct this by striking on what seems to him slightly the other side. Thus, if he, whilst aiming truly, brings the ball back to baulk invariably to the right of the central line, he should strike at what seems to him slightly to the left of its centre; if by doing so he brings the ball back over the spots, he may be assured that he has found the true centre of the ball, and by continuing the practice his eye will become educated, and the tendency to strike on the side will diminish or disappear. The stroke should be repeated till it is mastered at every possible strength, or, say, hard enough to cause the ball to travel four lengths of the table. When confidence in the power to strike a ball in the centre has been acquired, further practice should be made. Place the ball on one corner spot of the , play to the centre of the top cushion immediately behind the spot, and the ball should return over the spot on the other corner. This, too, is very useful practice; it familiarises the eye with the general truth of the axiom that the angle of reflexion is equal to the angle of incidence; and variations from this stroke (which need not be defined here, as any person of ordinary intelligence can multiply them indefinitely) will prove of constant use when it is necessary to play at a ball protected by baulk.

For the sake of clearness, one other example may be cited.

Place the ball on the right corner of the , measure a point on the top cushion an equal distance from the right side cushion, that point will be precisely opposite the right corner of the ; halve the distance between that point and the left top pocket, and at the half set up a mark—a piece of chalk laid on the cushion will do. If the ball be played correctly on to the place thus indicated, it will return to the left bottom pocket. Easier strokes of the same kind can be made across the table into any pocket, and confidence, which is an important factor in the game, is thus acquired. Before leaving the subject of these exercise strokes, it is desirable to emphasise the value to a beginner of acquiring a good style and of cultivating it incessantly till it becomes natural, and then he may, without harm, indulge occasionally in a game; if he begins with games he is certain to contract bad habits, which, becoming more confirmed the longer he plays, must result in increasing his difficulties and may never be wholly cured.

As regards indicating the strength to be used in playing various strokes, the best plan is to refer to the positions of the balls when they are at rest after a stroke; but as some rough guide may save beginners many trials, it has been usual to indicate by means of numbers the approximate strength to be used. Thus Strength No. 1 is a slow, or soft stroke; No. 2 harder, and so on till No. 5 or No. 6 may be taken as the greatest possible strength. Various measures have been adopted by different authorities; for our purposes in this book it is proposed to classify them thus:

Strength 1. From softest possible to that required for one length of the table.

Strength 2. From one length to two lengths of the table.

Strength 3. From two lengths to three lengths of the table.
