good gawd. Fischer was a prodigy. It had nothing to do with culture,"mommy and daddy" nothing to do with practice initially. He had an interest of course like any virtuoso and he took that innate ability all the way to the world championship.
Have you seen the movie "In Search of Bobby Fischer? the kid has talent and interest.
The parents recognize and channel it thru the Marshall Chess club guy.
You are trying to say it's not innate talent-it's simply practice. That is not true.
Many a person dedicated their time to chess and never got past the club level.
You have to be able to"see" the board, and the clearer you can, the better able you are to play.
That's all chess computers do - they number crunch.
But humans have an innate ability to reject unsound combinations -and that is where talent comes into play
Well, I am not sure why you'd focus too much on Fischer, a bit of an anomaly, to understand the variation within populations. But of course, he was also exposed to chess at an early age and played a lot.
Oh I see, you have missed the point or don't understand statistics. Of course, there is an innate component in the individual chess player. But, we are looking for what explains the variations within populations. More than anything that is due to cultural influences that determine participation rates and practice hours.
