Proper shooting posture, imagining the shot paths and points of contact and aiming the billiard shot with your dominant eye are the three important aspects of billiard techniques. Mastering these skills will help you to have a great game, not just once but with amazing consistency.
Admittedly, continuously practicing fundamentals cannot be too much fun for anyone, whether an advanced player or a learner. Remember however, that without the proper grip, bridge and stance even a professional almost certainly face an uphill struggle against consistency, no matter how much you learn about the game.
Tip- If you take the time to establish a strong foundation; when you find yourself in a slump you can always retrace your steps back to your fundamentals and you'll soon get your groove back.
Using your dominant eye
It is important that you use your dominant eye for lining up and aiming the balls. Develop a technique for positioning your body in such a way that that your dominant eye and the intended shot are perfectly aligned. To achieve this alignment sometimes requires that you practically rest your chin on the cue. Some of the most brilliant pool players have mastered this billiards technique resulting in some spellbinding game play.
Making the Shot Weigh the pros and cons prior to taking every shot, then make a decision based on your analysis and aim the shot accurately. The best way to do this is to draw a straight imaginary line from the object ball and let this line touch the centre of the opening to the pocket. Next, extend this line in such a way that it passes through the object ball to the side opposite the pocket. The point of intersection between this imaginary line and the edge of the object ball is the perfect place to hit the ball. This ensures that the ball will go to the intended or desired direction.
Visualizing the Shot
The next step in honing your pool technique is determining the exact point on the cue ball that will match up with the point identified on the object ball. At first glance, this may seem unattainable for the simple reason that you are absolutely standing behind the cue ball. However, this hurdle can be removed by visual means, which implies that you use your imagination to project where the object ball will be it comes in contact with the cue ball and ensure that both balls are aligned towards the pocket.
Getting a Good Grip
While producing astounding shots using unorthodox grips make for great drama, for starters you are better off employing the simple, consistent grip, which is neither too tight nor too loose. Holding the cue too tightly means your wrists cannot be released smoothly and quickly enough to produce a fluid stroke. On the other hand, you will find you are unable to take precise and powerful shots if you hold the cue very loosely. An ideal grip is one in which the cue is held mainly in the fingers and not the palm of the hand, leaving the wrist flat in the plane that is formed between the lower and upper arm. As with any other game of skill, practice is key to mastering the right billiards technique.
