Okay -- I just watched the "Corey 76" video that Dennis Walsh kindly made available. I must be missing something. Is there now some kind of chalkless cut tip, or self-caulking tip, out there? Or does Corey Deuel just not like chalk when playing straight pool? During the course of a 76 ball run, he rarely, if ever, chalked his tip. I put it this way because while watching, I was presuming that he was chalking while off camera a couple of times. But maybe he was doing something else, such as removing chalk from his tip, whatever chalk could have been there. What was visible were a couple of occasions when he turned his cue upside down and spun the tip on the carpet, obviously, it would seem, to remove chalk (again, whatever chalk could have been there). Also, on multiple occasions he had the referee mark the position of the cue ball and then clean it. Was all of this to avoid skidding shots? Is this a routine that is not new for him (and perhaps others) depending on the equipment and conditions? I have been watching high level play (only on videos) for something less than a year, so I've seen a limited number of runs/matches, and maybe this approach doesn't surprise all you veterans, but I'm shaking my head ...
