All these strokes should be played medium strength, say No. 1 or 2; in practice it will be found that the angle of reflexion varies somewhat with the strength, and in a less degree with the table.
As great accuracy is of the highest importance in playing winning hazards, it is evident that, when either ball has a considerable distance to travel, the stroke should not be played too slowly; for in a very slow stroke imperfections of ball or table tell more than when greater strength is used. Also, before leaving the subject, it is desirable to impress the reader strongly with the importance of the remarks on pages [145]–6 respecting play into a more or less blind pocket. Attention to them is essential to good spot play and also to what is called play at the top of the table. Clearing the dangerous shoulder of the pocket is the secret of success.
We now proceed to losing hazards, which with most amateurs form the mainstay of the game; partly because being easier than winning hazards, they are usually taught first, but mainly because they are possible with a slovenly style and inaccurate striking which effectually prevent success with winners. In reality, however, they will repay care and accuracy as much as any other stroke, because, unless ball 2 be struck in the proper place, it will not travel in the desired path, and the result of a poor stroke may be success as regards the hazard, coupled with leaving ball 2 hopelessly safe. When played with intelligence and with due regard to the position of ball 2 after the stroke, they form most excellent practice. Following the usual custom, these strokes may be divided into short and long losers, and each will be separately treated; at present, of course, plain strokes only being considered. It is convenient to take the half-ball hazard as the standard or typical stroke; it is the easiest for the reason given at p. [133], because aim is taken at the edge of ball 2, a well-defined mark, instead of at an indefinite point on the ball’s surface. Moreover, on billiard-tables certain positions are recognised as affording half-ball losers, and these are most valuable to a player as supplying the means, during play, of testing and correcting his strokes or his judgment of angles. It often happens from many causes that a man’s eye or nerve partially fails, which failure destroys confidence and begets still worse play; he probably before long gets a stroke from one of the many positions which should be played half-ball. The mere effort to recognise the situation tends to arrest demoralisation, whilst the success which follows correct recognition goes far to restore equanimity and confidence. That is one reason against wantonly altering the positions of the spots on the table, the size of the D and such matters; though, no doubt, if the game can thereby be certainly improved, the alteration is justified, and in time players will learn similar positions under the altered circumstances. Hitherto such changes have been made rather with the view of cramping the play of one or two men, and so placing others less able or less diligent on a par with them, than with the object of making an undeniable improvement in the game. Such modifications under the pretext of reform are much to be deprecated.
Taking the billiard, pyramid, and centre spots as fixed points on the table, Diagram III. shows with sufficient accuracy the lines of half-ball strokes to the top pockets. Let the billiard spot be considered first. From either top pocket there is a half-ball stroke to the opposite one; also from either middle pocket there is similarly a half-ball hazard into the opposite top pocket. Next, from a ball placed on the pyramid spot there are half-ball hazards from either corner of the D into the top pockets; and, lastly, from a ball on the centre spot, half-ball strokes to either top pocket may be made from positions about 7½ in. to the right and left of the centre spot of baulk. Precise accuracy in definition of these strokes is not attempted; tables and balls vary, whilst no two men strike exactly alike; hence each must work out for himself the exact position for a half-ball stroke; it will in every case be reasonably near the lines indicated.
Diagram IV. illustrates several losing hazards, all good for practice. For the group marked A, place ball 1 on an imaginary line from the centre of the red spot to the upper edge of the shoulder of the left middle pocket about half-way between them, where it can be conveniently reached by the player; it is then in position for a gentle half-ball stroke to the right top pocket. When correctly played, impact with ball 2 takes place on the central longitudinal line of the table, and consequently 2 travels to the top cushion on that line, and returns on the same path a shorter or greater distance according to the strength of stroke. A very gentle one will bring ball 2 back to the spot; a medium stroke will result in leaving it near the pyramid spot, and it can be brought further down the table if desired; but for practice at this stage endeavour should be made to leave ball 2 between the red and pyramid spots on the centre line. If this is effected, ball 2 has been truly struck; should it return to the right of the line it has been struck too full, and if it rests to the left of the line too fine. So that here again we have an index which points out error and shows what is required for its correction. The hazard is so easy that after a little practice it will seldom be missed, and for that reason it should be worked at till it becomes what is called a certainty.
Diagram III.
Then from A lay off, in the direction of the right middle pocket, a series of positions marked A′ A″ A‴ A⁗, each about 1¾ in. from the other, and from each of these play the hazard. The point of impact should be the same in every case, therefore the point of aim will vary slightly with the change of position; but the chief variation in the stroke lies in the strength employed.
For the position A′ the strength is about No. 2, and ball 2 should be left on the central line L L between the centre spot and the bottom cushion. For A″ the same stroke a little stronger, ball 2 returning from the bottom cushion towards the centre spot: and so on. It is seldom necessary to practise beyond A‴ in dealing with plain strokes. The strength required for this stroke is considerable approaching No. 4, and ball 2 should travel beyond twice the length of the table. In all these strokes endeavour should be made to keep ball 2 travelling on the line L L; this will be found not quite an easy matter, and sometimes divergence may not be from any fault of striking, for an imperfection in the ball which might account for an error of half an inch or less in 6 ft. would produce a perceptible deviation during a journey of 24 to 30 ft. Nevertheless, the prime source of failure is to be looked for in a faulty method on the part of the player, who, if he cannot easily remedy what is wrong, should without hesitation revert to the practice previously prescribed. After some work at this he will probably find that ball 1 was not being truly struck, and will amend the fault. These strokes should then be transferred to the other side of the table, making the hazards into the left top pocket. They are very conveniently played with the left hand, and the player who can use both hands almost indifferently has a great advantage over a purely one-handed performer. It is entirely, we think, a matter of resolution and of practice. At any rate, these strokes should be played from both sides of the table till they can be made without difficulty.
