A tangent line in pool, is described as the line that indicates direction to the cue ball after it impinges the object ball. This helps you to strengthen your positioning of the cue ball for playing the next short and getting away with all those scratches. Besides, cue ball and object ball, there is a ghost ball that gives you the position of your cue ball after it contacts the object ball. The perfect idea to ascertain the tangent line is to imagine it in the form of a cross (+). Next, you draw a line that passes exactly from the center of ghost ball, object ball and to center of pocket. Draw another line from the line drawn earlier in cross shape and make it pass through the center of the ghost ball and finally end it at the rail. This will be the path traversed by the cue ball via the center English, after it impinges object ball. Tangent line can only be changed by the high or low English points. I would personally advice you to start playing the game after practicing different English and speed. In course of time, you shall become comfortable in using the exact English to use to get position on the cue ball. For all the novice players, I would say that they should practice playing the same shot, using center English. This will give them a better idea about tangent line.
Shaping your tip is an important part that comes above in pool instructions. You have very fair chances of miscuing, if you apply English with a mushroomed flat tip. You can practice with different types of tip shapers, viz, nickel, dime etc. It is important to know here that placing a particular tip behind top of the tip, your tip will become like that. There are tip checkers such as the grove one, which helps you to ascertain, whether tip needs any shape. The practice is that you try fixing the tip checker by placing it on top of the tip. If it fits aptly then your tip is in shape, otherwise, it requires shaping. Furthermore, as the part of these pool instructions, if you find that tip is in a perfect shape and you are still miscuing frequently, then there is a possibility of a layered tip of glue. The best way out in such a condition would be that you reshape the tip until the layer of glue is removed.
To play pool is an art to master. Many people have problem in tackling the Straight in shots. Keep in mind that when you shoot high on the cue ball, it will hit the object ball hard and direct it straight into the pocket. And if you shoot the cue ball low, then either you have the chances that cue ball stops after a while or it reverses the direction. The shooting center works well, only if object ball and cue ball are close to each other. If the shooting center is at a distance, then it might result in cue ball drifting in forward direction and there is possibility of encountering the scratches. Remember, speed has an important role, when you play the shots. Therefore, it is necessary that you practice straight in shots repeatedly, using different speeds and techniques. There is a famous ism… Practice makes man perfect.
