It's way beyond that. The difference between the top 50 or so players and more importantly, the top 10 is focus/concentration
.- I think you are watching too much Shaolin Kung Fu movies
While I'm not a first class player (yet), I'm close friends with some of them.
(I'm very lucky to live very nearby to two 3-C U.S. "Meccas": Doral Billiards and New Wave Billiards, both in Miami, FL)
I'm close friends to Carlos Hallon, a player once only surpassed by Sang Lee (his cousin, Frank, also an very good player, is my mentor). I've known and, of course, talked to players the size of Ramon Rodriguez (# 14 UMB)
When I ask them how can I improve my game, they all invariably gives the same advices:
1.- Learn how to make and practice the shots (specially the hard ones) several times till you can make each it at least 10 times consecutively and then do do that every day of your life.
2.- Work on your "essentials" (Stance, Stroke, Follow through, etc) till you
makes 'em BY REFLEX, automatically (that's it without even thinking about it, let alone concentrate)
3.- Learn and practice to death the several Mathematical Systems.
Yes, concentration is important in billiards, as is important in a lot of human activities.
But to a point.
And that certain quantity of concentration you need only practice will give.
Blomdahl, Caudron, etc they all have some things in common:
They all started to play at a very early age ( Sayginer at 14, Blomdahl at 5!!) and they all practice several hours a day every day of their lives (Dani Sanchez (# 2 UMB) once said that he played
at least 4 hours daily)
When they stop practicing, their game goes down.
3-C Billiards is a game of skills and logic, in which practice and, mainly
Know-how is more important than anything else.
And Tiger Woods?
I bet you I can mop the floor with him in a 3 cushions game, even with his "superhuman" concentration abilities.
Unless, of course he knows how to make caroms better than me.
