what's Duckie system? Thanks
There is no duckie system. It is not a system at all. Its a method I use that is based on the ghost ball contact patch concept and not the contact point concept. It is not my idea, but an extension of what others before me have written, in specific, Babe Cranfield. When I was developing this idea, I received a copy of his Straight Pool Bible and in it was the Spot on the Table concept plus the Arrow to be made for training. I just added a little more to what he started. Its nothing new, nor is it mine.
Instead of contact points on the OB that some people use for aiming, I use the contact patch of the CB and try to put it on a spot on the table that is 1/2 CB from the equator of the OB and is on the same line as the OB contact point to the pocket.
The contact patch is where the CB meets the table. For any shot on the table there is only one spot on the table that will make the OB go where you want regardless of where the CB is on the table. I just try to put the CB contact patch on that spot on the table.
Then there is understanding the geometry of a shot using the ghostball concept. This is not for aiming, but to help understand the effects distance and angles have on a shot and what can and can not be done. It can be used to help determine where the spot is, but not used in getting it there.
There is only one way to learn to get the CB to that spot, practice......trail and error....nothing more and nothing less. Practice......
Then there is the Arrow by Arthur Cranfield that is a training device that can be used in practice that points to the spot on the table that makes the CB go where you want. Google it....
