English: Billiards: red winning hazards and cannons. Suppose the red ball is over the right-hand middle pocket at H. The proper professional play would be to put the ball in the pocket, and then run up the table towards L, and try and get into position for the spot, but the ordinary amateur, who, when he gets into position for the spot, can only make one hazard and then breaks down, had better not play for the spot at all. In the position given in the diagram, it would be better play to put the red ball in the pocket, and try and leave your own ball at H1; then there is a certain losing hazard next time off the red into the left-hand top pocket. Again, suppose the balls are left in the position W (the white ball), and X (the red ball), many beginners would play for the six stroke, but it would be very bad play, as the red ball would be on the spot, and the striker in hand. The proper play is to put the red ball in the pocket and leave your own ball in the jaws of the pocket, thus leaving a certain losing hazard—in off the red into the opposite top pocket—next time; a stroke, too, in which it is always easy to leave the red ball over the middle pocket in the stroke following...(Cannons) Suppose the red ball is on the spot S, the white ball at B, and the player in hand. There is, of course, an easy cannon left, but how ought he to play it so as to leave an easy score next time? The game here is to leave the balls together at the end of the stroke. The striker spots his ball at A in baulk, so as to strike B the ordinary half-ball stroke. The stroke should be played slowly, so that the white ball rebounds off the left-hand upper side cushion at C, and travels towards D. The player's own ball hits the red gently, and all three balls are left close together, near the top of the table, one of the best positions possible.
