In another thread, there was a long debate over whether Mosconi, on occasion, used a slip stroke. Without going into the somewhat tedious hair-splitting about the definition of a slip stroke, for me, it entails sliding your hand toward the butt of the cue during the final backstroke. When I tried it 50 years ago, I did it to put more juice or spin on the cue ball. My slip stroke involved sliding my grip hand 2, 3, or, at most, 4 inches back toward the butt of the cue. For me, it seemed to increase the amount of spin on the cue ball at the expense of accuracy.
Just wondered if any of you old slip strokers, or young ones for that matter, agree or disagree with the purpose of the stroke.
