When watching people break ( 8 ball) I see them place the cue ball left side, center, right side and center close to the back rail. As a new player where should I be placing the cue ball to get the best break? Has there been any studies done using physics which spot will give you the most force against the rack if the cue ball is placed in these different spots and an equal force is used on the cue ball from each of these spots?
