i'm reading the rules on racking/breaking. really interesting. not sure if they revised/added some rules.
RACKING BALLS:
A plastic rack sheet will be used for racking of balls to make perfect racking and save the time for racking by a referee. Players are not permitted to touch the balls once racked.
BREAK-SHOT RULES:
The following rules are to be an addition to the WPA 9-Ball rules. At least three (3) object balls must either be pocketed or pass the head string as a result of a break in order for it to be legal. Any combination of the above (i.e. 1 object ball pocketed and 2 object balls passing the head string, or 2 object balls pocketed and 1 object ball passing the head string) is also legal. Regardless of whether any balls are pocketed if a player fails to earn the required rules, it will be considered an illegal break (this is not the same as a foul break as defined in the WPA Rules)
After an illegal break:
1) Opponent has the option either to accept the table as it is, or hand it back to the player that performedthe break.
2) In case the opponent accepts the table as it is, the player will not be allowed to perform a push-out.
3) If the table is handed back to the player that performed the break, the player is allowed to perform a push-out.
4) If 9-ball is pocketed in a legal break, the player wins the game. If in case of an illegal break, 9-ball is re-spotted before play is continued, then opponent has an option.
