Let's see the research studies that you're citing.
As I posted earlier, the top chess players have prodigious memories, which helps them to excel at the game. The following research is consistent with what I posted:

The Specificity of Experts’ Superior Memory
The most influential research of experts’ memories focussed initially on chess experts. In their pioneering studies Chase and Simon (1973) showed superior memory for chess positions by chess experts. Chess players ranging from beginners to international masters were shown a position from an actual chess game (such as the one illustrated in panel A of Figure 1) for a brief time (normally 5 seconds) and then asked to recall the location of all the chess pieces. The ability to recall increased as a function of chess skill. Beginners at chess were able to recall the correct location of about four pieces, whereas international-level players recalled virtually all of the more than twenty pieces.
To rule out that the superior memory of chess experts reflects a general superior ability to store any kind of visual information, Chase and Simon (1973) had chess players recall chessboards with randomly placed pieces (as illustrated in Panel B of Figure 1). With briefly presented random chessboards, players at all levels of skill had the same poor recall performance and were able to recall the correct location of only about four pieces—a performance comparable with that of chess beginners for actual positions from chess games. Further, Chase and Simon (1973) showed that when an actual chess position was shown using an unfamiliar notation (see Panel C in Figure 1), the chess expert was able to display a similar level of superior memory performance after a brief period of adjustment. This result implies that the superior memory of experts is not photographic and requires arrangements of chess pieces that can be encoded using associations to the experts’ extensive knowledge of chess. Since Chase and Simon’s classic study, investigators have shown that level of expertise is related to superior memory performance for representative stimuli in the associated domain, such as computer programming,, basketball, and dance, and that this superiority is mediated by increased knowledge and domain-specific skills (for a recent review, see Ericsson, Patel & Kintsch, 2000).
And what you highlighted in red and the other observations prove exactly what I said. Namely skill, in this case recall, improves with practice.
And as I said when chess players learn chess they learn the language of chess. Same as speaking english, you do it because you learned that arranging the letters in a particular way means something. Take those same 26 letters and make a new language that doesn't conform to the rules you use and you will be completely lost trying to communicate using words.
We learn the language of pool and even we can't perform a certain task consistently we can see a layout and know what to do whereas a beginner does not.
So then what is "talent"?
Hand-eye coordination?
Faster synapses?
Empathy?
Cognition?
Calmness under pressure? (Earl then is not talented at all)
I mean I can certainly accept that some brains are "wired" differently. What else explains autistic savants? What else explains retardation? If a person has a learning disability then another one can have a learning ability. But it's neurological and not specific to any particular field.
The thing is that you can NEVER know how great someone might have been in some other field because to BE great in one field requires quite a lot of energy and focus. And also the circumstances for each are different.
Until you have a world where humans are grown in lab environments and experimented on with every conceivable control you simply have to accept that each and every one of us is unique. We all grow up in different circumstances, with different influences, different opportunities.
And we can barely measure what effect any of those variables had on us and our resulting performances. So to those of you who think that you are either born with it or not I feel sorry for you. Most people who are very successful resent being classified as a freak of nature and prefer to be thought of as someone who was willing to work harder than everyone else to get where they wanted to be. You find that over and over and over in biographies of highly successful people.
The common denominator among them all?
Drive.
Determination.
Never quitting, always pushing the envelope, what top athletes and the scientists who train them call threshhold training. What makes people better is simply pushing farther each time. Going just beyond the limit of where you went before. I could give you examples of this in my own business but they would be completely wasted on you. But the end result is that I have taken a couple people with ZERO experience in leather tooling and made them very good inside six months by pushing them to think and grow each time they put the tool to the leather.
I would hope you would be offended if I told you that your chess prowess came from natural talent and not from intense study of chess.
If you start to look around you find plenty of stories of people taking up something later in life and becoming the best or among the elite at it.
I think that in MOST cases people do have the ability to improve dramatically. What's that old saw about us only using ten percent of our brains....... what will the world look like when we figure out how to use the other 90%.
Imagine that world.
