The losing hazard may be easily made as shown from either side of ball 2. Take first that from the left side. Play ball 1 one-quarter right, medium No. 1 strength, so as just to pass ball 2 to the left without touching; ball 1 will return from within the shoulder, strike ball 2, and fall into the pocket. For the hazard from the right of ball 2, ball 1 is played one-quarter left, to pass the right of ball 2.

Example C is precisely the same stroke into a corner pocket.

Example D may occasionally be of use, though generally a miss would be the proper game under the circumstances. Ball 1 is supposed to be in hand, ball 3 having stopped near ball 2 on the spot, but not sufficiently straight above it to warrant playing for the kiss cannon. In this case the knowledge acquired by playing an old fancy stroke—to make the losing hazard off ball 2 from baulk by playing bricole—is utilised. In that stroke an approximate guide as to the point of aim on the side cushion was obtained by aligning the cue so as to pass over the left bottom pocket, and the left corner of the : the prolongation of that line indicated the point. Hence, by aiming a little above the point thus found, ball 2 is struck on the right side, and the cannon is possible. Place ball 1 on the left corner of the , play a free No. 1 strength at the side cushion, aiming as directed. One or two trials will determine the correct point of aim with a given strength; if the strength is altered, the angle of reflexion will also alter.

Example E, on the other hand, is perfectly simple and most useful. Measurements are unnecessary. Play ball 1 to the cushion with slight right side; ball 2 will be pocketed, and ball 1 will rest in a good position for a losing hazard from spot into the right top pocket.

Example F.—Ball 1 in hand, balls 2 and 3 as shown about the diameter of a ball or a little more from the side cushion, so placed that the fine cannon from 2 to 3 would be very difficult. By placing ball 1 on the baulk-line as shown, and by playing with a little right side behind ball 2, ball 1 will, after impact, run down the cushion and make the cannon. When the eye is trained, ball 2 may be a considerable distance—say six or eight inches—from the cushion, and the stroke may be made with a reasonable chance of success, whereas played in any other way the result would almost certainly be failure.

Plants (see definition in Chapter III.) are perhaps more connected with pyramids and pool than with billiards; nevertheless, they may be occasionally used, and, therefore, must be briefly considered. The simplest form is when the centres of balls 2 and 3 are on a straight line which leads to the centre of a pocket. (See Diagram XII.)
