If you had played 10 dollar nine ball with Kenny , be glad you didn't play. {Unless you played like Rempe, Buddy, Marino speed.} Even then it probably wouldn't have been worth the torture.
He didn't play as good for big money but what working man does?
If you never got a chance to watch him play you missed something pretty special, he plays with all kinds of spin and moves the cueball around more than any good player I know , but he used to get out from everywhere.
The only thing I think he knows about systems is "Thunk it a little on this side, {his exact words}.
I noticed in the 1960s that he always addressed the cue ball at about 3 oclock which explains why he always got so much english on the ball ,{backhand english}, he said he did it so he could aim better.
