Yes, I may have assumed that all other variables are held constant, which is usually not the case. Although on your other point, I feel as though your argument sounds more like the 10,000 Hour rule popularised by Malcom Gladwell which I don't 100% agree with.

There is definitely the aspect of talent. I've seen (and arbitrated) players who began at an early age, had the most effective training and became completely average or even stagnated. And I've also interacted with those who heightened their chess skills in a really short time and are among the highest rated players.

I've always thought of chess being more about talent rather than the measure of IQ but it also depends on what one's definition of "smart" really is.

Corrected. Thanks.
