The American Association (APA) was founded in 1981 by professional pool players Terry Bell and Larry Hubbart, although with roots dating back to the National Pool League (NPL), founded in 1979. The APA conducts a system of franchised-based local amateur leagues of pool (pocket billiards) competition, including both eight-ball and nine-ball, with a unified APA ruleset. The organization, which has affiliates in Canada and Japan, hosts regional tournaments the winners of which qualify for the annual APA international tournament played in Las Vegas, Nevada. The organization claims to be the world's largest pool league, and cites an individual membership roster of approximately 265,000 players. The APA employs a handicapping system called "the Equalizer" that allows players of all ability to compete on an equal basis. These systems are explained below for both nine-ball and eight-ball. The normal APA team consist of 5 -format competitions (similar to matches in the USA Pool League, and very different from the format used by the BCA Pool League and VNEA). However, APA organizers at the local level often set up non-team tournaments, play, and other formats, and the annual championships feature both individual and team play. == Nine-ball Equalizer == In APA nine-ball, two players compete until one person reaches a score determined by their respective skill level. The scoring is recorded by awarding a single point for potting the balls numbered 1 through 8 and two points for the 9 ball. For example, if Player A breaks and makes two balls on the break (not including the 9 ball), that player would have 2 points for the rack and continue shooting. If the player "runs the table" (makes all the balls without missing), they score 10 points for the rack (the maximum) as they would have scored 8 points for the balls 1 through 8 and then 2 for the 9 ball. The match ends when a player reaches the number required for their respective skill level. The table below lists the number of balls needed for a player of each skill level to win their match. Note: APA nine-ball is not a traditional style that is typically played by billiard enthusiasts. Even though it does follow traditional rotation characteristics, it resembles more of a straight pool (14.1) tradition by opponents racing to a specific number of balls pocketed. The lowest skill level in APA nine-ball is a "1" while the highest skill level is a "9". Using the table above, you can see that if Player A is rated a "2" and plays Player B who is rated a "6", then Player A wins if he scores 19 points before Player B scores 46 points. Conversely, for Player B to win the match, he must score 46 points before Player A scores 19 points. As APA nine-ball is based on points and not games won (for example BCA League nine-ball is based on games won, where the winner of each game is the player potting the 9 ball), a match can end before all the balls of a given rack have been potted. Using the previous Player A (Skill Level 2) vs. Player B (Skill Level 6) example, let's say that the Player B is breaking a new rack leading 44–16. In this case, Player A needs 3 points to win and Player B needs 2 points to win. The match ends when either player earns the needed points to win regardless of the number of balls remaining on the table. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「American Poolplayers Association」の詳細全文を読む スポンサード リンク
