I enjoy and learn things from watching the pro's playing. I also believe some of them use a bit of negative psych on their opponent. I'm ok with that as it is a "big boy" game at that level. Johnny Archer, what a talent and he seems like a real gentlemen that loves the game. Is every table he plays on dirty, he constantly picks at the felt. Alex Pagulyan, the perennial crowd favorite, he starts and stops and walks around the table and then repeats. Dennis Orcolo is similar with the down on the shot a few times then back up. Earl Strickland, probably the best 9 ball player ever, those tantrums, wow! Maybe he can't help it. SVB and his attention to the rack. The pointing to where the cue ball should of went when things went wrong is common now. I think much of this is designed to put stress on their opponent, or it relieves some of their own stress. Maybe I'm wrong. Pool is one of the few games where the show of emotion is usually subdued, so they have to let stress out some where.
