Applying english on the ball is like applying oil on the table. When english is applied at the side where the cue ball will naturally ricochet to, the cue ball will travel far enough even with just a little effort from the Executioner. Oiling the table is easiest especially on wide angles. At this point, I have to mention two important tools regarding angles on the table. The first tool is bank knowledge.
Some players draw an imaginary bisector as their reference point.
You can go on and on through the different rails giving and getting the same angles as long as the cue ball keeps on rolling. If you plot the ongoing lines, you will find out that they will be parallel, if not aligned with the lines that run through the dots on the table. This is what they call the diamond system. All the angles in a diamond are the same. Without the side pockets, as in carom tables, one can make a perfect diamond.
