Steve, I have often wondered of late as to what just was the motive of Grady presenting the Grady alternative rule. Being a hustler, I am sure he was always looking for an advantage. And could it be that the down table game did not suit him, and he wanted to have he and his opponent to stay in the trenches. Was stack play his suit, it sure favors the more knowledgeable and experienced player. I would think. We seen this happen with Scott vs. Orcollo, for on the final day Scott played to keep it stack play and caught up quite a bit.
Also why 4 balls, what is so magical about it? I know when we were discussing express OP, you offered up 2 balls down table and then a ball spots.
I once brought up that only 1 ball can be sent down table consecutively by each player, and on the next shot by the player who originally sent the first ball down table, it then is not allowed to send another ball down table. In other words; "stop the down table play before it gets out of hand". This idea does not favor the first player to send a ball down table.
I guess the Grady Rule does speed up the game, I really do not know! Whitey
