This and essentially throwing the cue through the ball. I use to do this 20 years ago as part of my arsenal. No longer need too. I can draw perfectly fine now.
At what point in his stroke did the slip occur?
I couldn't get the hang of it - you know less than a 1000 hours to work it out, so I approached the power draw by traditional techniques. I did manage to get the ball action I was looking for a couple times - burn rubber and then hook up like a rocket but still no available 1000 hours.
Ko made a very good point though. The cue in free flight won't be influenced by extraneous forces. ie bad stroke; whatever...
Even if you don't use the slip on draws...drawing the ball normally you want to keep your wrist loose. You don't want a "fundamentally sound grip" to power draw.
What I started on was instead of mindlessly following through, I took a bit from the Ray Martin book - shoot like the cueball isn't there or words to that effect. Instead of staring down the CB with the evil eye, I lightened up and shot about one ball past the CB. This made all the difference.
Specifically? I don't know. I just always thought his stroke looked so smooth.
That is a slip stroke. I think the OP is talking about a "stroke slip". To some people, these are very, very different kinds of stroke.
If a player doesn't already know what that is and how to cue it, I wouldn't recommend attempting to incorporate it into your stroke. Rabbit holes.
I agree with you for the vast majority. I was lucky enough to watch him play when I was a teen… Jimmy was friend of my father. When the Color of Money was released one of the local movie theaters set him up with a pool table (trick shots) in the lobby to promote the movie. I’ve looked at Jimmy’s slip stoke on different videos probably a hundred times. It seems like he used his slip stroke when he wanted to put some level of juice on the ball as he didn’t use it on every shot. Also when he used the slip stroke it seems a though he didn’t want his back hand to follow through or that‘s how he insured that cue ball contact was at the mid point of his backhand pendulum. Thats my observation and guess. It was definitely second nature to him.
