So SeniorTom posted a question the other day about what constituted a foul. I was recently in a similar situation: An object ball was frozen to a rail. I lightly hit the object ball with the cue ball causing the object ball to roll a few inches out onto the table without contacting another rail. The cue ball, after contacting the frozen object ball, contacted the rail that the now dislodged object ball had been frozen to without going to any other rail. I claimed this was a legal shot but the other guy claimed it was a foul. He said that either the object ball or cue ball must contact a rail other than the one the object ball was frozen to. I relented but now kind of regret it. After Bob was kind enough to post a link to the WPA Rules in the other thread, I read the ones that seem to apply (6.3 and 8.4). Under 6.3, the cue ball contacted the object ball (albeit frozen to the rail, but the rule doesn’t say it can’t be). After that contact, the cue ball was driven to a rail, which 6.3 explicitly allows for. Rule 8.4 says ”A ball is said to be driven to a rail if it is not touching that rail and then touches that rail.” It doesn’t say that the ball driven to the rail must be an object ball and not the cue ball. The cue ball under 8.4, was not touching that rail, and then touched it. Am I missing something or is there another Rule that touches on the issue? The Rules follow just for convenience.
Rule 6.3: If no ball is pocketed on a shot, the cue ball must contact an object ball, and after that contact at least one ball (cue ball or any object ball) must be driven to a rail, or the shot is a foul. (See 8.4 Driven to a Rail.)
Rule 8.4: A ball is said to be driven to a rail if it is not touching that rail and then touches that rail. A ball touching a rail at the start of a shot (said to be “frozen” to the rail) is not considered driven to that rail unless it leaves the rail and returns. A ball that is pocketed or driven off the table is also considered to have been driven to a rail. A ball is assumed not to be frozen to any rail unless it is declared frozen by the referee, the shooter, or the opponent. See also Regulation 29, Calling Frozen Balls.
