When I watched Keith play at Hard Times Costa Mesa in 1976 or so, he was beating everyone at every game. Bar box, 9 ball, short rack snooker and even starting to get good at one pocket. The thing was that at that time he played with a scary intensity and precision and he shot quickly and with immense self confidence, selecting outrageous shots that no one else would attempt, and for big money. Of course he had his entourage and backers which made it even more intimidating for those trying to match up with him. When I saw vids of him playing later he had a very relaxed style and holding the cue at the very end. In Costa Mesa he held the cue way up almost past the grip winding and with that wild intensity that I guess he outgrew later.
At his best, Little Keith played like God Himself, utterly perfect. I have never seen anyone else get to the level of Keith in the late 70's. The closest you will see to his mastery of the cue is to watch videos of Ronnie O'sullivan. Both are right brain geniuses whose talent can never be equaled by practice alone. Mozart in music, Clark or Senna driving an F1 car, Jordan in the last minute of the NBA finals, Tiger a few years ago. Genius easier admired than explained. Keith was in this rare class.
