I see dead balls
I can't find the video, but in a Challenge of Champions pool tournament, the rule was that you had to call the nine. Efren forgot to call a hanger and lost a game. It's not supposed to be about that sort of thing and avoiding bullcrap like that is important to preserve the fairness and structure of the game.Yes I agree they are. However, they would.be better if they were call shot. Chinese 8 ball used to be call shot, with a strict rule on the 8 where you had to call the shot even it was obvious. They changed it, in their words to "increase the luck'. I'm yet to see an instance of this change having a positive impact on a match.
Taking out call shot also removes the possibility of the opponent either misunderstanding your call or maliciously pretending not to have heard you call it or to not have seen you point the cue or whatever you did to call it. I've had people do both of those things to me. Strickland had an incident where he accidentally called the wrong ball, even though it was obvious which ball he was shooting. It's better to just avoid this whole problem all together.
