Speaking of Chess.....There is a "very good" chess player out there named Josh Waitzkins. Google him, go to Amazon, and by his book, the "Art of Learning". I encourage all my BJJ students to read this book at the blue belt level.
Josh gets it 100%. What it takes to win in high level sport and in life.
Ironically Josh left chess behind after "mastering" it, and moved on to Shan Shou and Tai Chi. And guess what...now he is working with Marcelo Garcia in BJJ up in New York!
It is more than saying "hey hold on a minute, how do you do that!". It requires development of a completely different way and methods of training that most folks don't have the time or conviction (heart) to do.
...buy the book and read it, it sums up very succinctly everything we are discussing here.
My Teacher was a very good chess player too. I mean very good, he used to play twenty at a time in charity events. He drew once with chess master at the time from cuba. That was his level he reached and it had taken over his life to such an extent it ended up chess or his wife. The wife won.
That's probably why I mentioned it for listening to him explain all about the why's and wherefores over the years I think I have heard enough.
Please no more! ARghhhhhhhh......
