It’s all about the rack. In the game of billiards, one of the first most important things is racking the balls. Players want to receive a properly racked set for a game against their opponent. This usually means the balls are racked tightly together with no spaces in between. A good rack not only has no spaces in between the lead balls but also no spaces in between the back corner balls. When a rack is tight most of the energy from the break transfers to the rack; however, when a rack is loose, some of that energy is lost. For the breaker to get the best spread it is recommended the balls in the rack be touching.
At the amateur level, although not all racks will come out perfect if a breaker is dissatisfied with a rack, they can request a re-rack. Is there a limit to the amount of requests they can make? Technically not; however, several re-rack attempts can be made but what if the breaker still continues to be dissatisfied? Is there a fine line for repeated requests to be considered poor sportsmanship or even sharking? The racking player may also recommend the opponent rack their own set of balls if the breaker is seemingly crossing that line. Don’t allow an opponent to hang their rack in your brain. Most importantly, have fun while being competitive.
