While playing billiards or snooker, stance is one of the most important points. Everybody has its own posture or stance, but you need to know certain things about it before hand and outright.
Equilibrium - A body in state of equilibrium poses balance and restricts body movement thoroughly, baring the arms, which move to give a swing to cue stick. You can keep your body in equilibrium by spreading the feet so that your body weight is evenly distributed on both your feet. Now you move your left foot in the front, if you are right handed and vice versa. Next, make your arm position at 90 degrees to the table surface. In this position you can hit the cue ball with smooth movement and besides, the stroke will be straight.
In order to give free swing to your arm, make your body angle at an acute 30 degrees to the cue stick. Ensure that you do not touch or friction with your hip when you take it back. Make your body at ease. Lastly, level the cue stick to the maximum by lowering the body trunk in alignment with the cue stick. Well, all this also largely depends on your tallness too. You know guys; it is all the tactics about how to play billiards.
When you ask yourself as to how to play snooker, the only thing that comes into mind is positioning. When you plan the shot, your head lies in sync with the aim line, and the cue stick lays at center of head or down right the dominant eye. Keep your head angled at 90 degrees and rest comes automatic.
