Shoot Pool, not people
The answer to the OP's original question is Practice, Practice, Practice!
Some people just never get it. I think some people are just not 'wired' to see the relationship(s) of colliding spheres.
I'll say one thing for Geno. I been working on alignment.
Glad to see you are starting to see the light. Like Rodney Morris wrote in my lessons notebook. """ I saw the light. 6/9/2009. Signed Rodney " The Rocket" Morris.
When giving a lesson I sometimes use this method when nothing else seems to work. Stand in the preshot and be in your starting position with your body turned to 2:00 if your right handed. Move your head over so you are lined up in the preshot. Doing this will kinda get the body where it needs to be and will help get the eyes there naturally. Come down on the shot looking at the object ball, keeping the cue ball in your line of sight. Once down you can look at the cue ball and get the cue where it needs to be exactly. If you kept your head still the shot will still look as good as it did when you first got down.Not to be a dick about this but I'm still on my cue ball last method and double vision sighting. The hard part is zeroing out the center ball, 180 degree straight line. For instance I can usually shoot a dead cue ball but not exactly straight at the object ball. The inverse where I nail the 180 degree angle but the ball has some spin on it also comes up. Finding that spot so far has been like learning to ice skate - I can't at all. Still plugging away. Incidentally, cue ball last is working and has improved considerably with the 180 degree drills. I modified my PSR to arrive at correct cue placement before getting down and now just get down "around" where the cue already is. It's very accurate.
Apologies to da Rocket.
You seem to assume that only a Champion or one who has won several tournaments can teach...Some of the best Football coaches in history were not great or champion players....Same with Basketball and Baseball, great managers and coaches but were never great or champions them selves...Some can play like a champion but they can't seem to teach the game...Some don't play as good but are great teachers.....Well Genomachino came to AZB years ago, hyping his "Perfect Aiming System" & DVD by the same name.
Hawking his $80.00 CD. If the man was some World Class player he would be a sponsored player. Non of the places like Pool Dawg, Muellers, Seberts, etc, have his "Perfect Aiming DVD" in their inventory for sale. Wonder why if it the holly grail?
Like I said before I have actually view the DVD, returned it to it owner, Fast Larry of Lawrenceville, GA. Say nothing that personally excited me.
Aiming or perfect aiming is only one small part of a person arsenal of tools to play pool. If you can not hit a ball straight down the length of a 9 foot table, and get it to roll back in a straight line, you got problems, and there are a lot of other, if's that are all skills one must master to become a better player.
Genomachino is a pretty good salesman, I expect he could make a good living selling Jewelery, Cars, or Hime Improvements. JMHO
