for one, to play chess, it does not take much financial resources to start. just a cheap chess set and board are fine. That is unlike sports such as golf. and you do not need a team of players to play, like football or soccer.
why distinctly, there have been a preponderance of top notch Jewish chess players relative to the number of Jews is beyond me.
However "Chosen people" has nothing to do with Jews having special rights or talents over others. Rabbis will tell you that Jews were chosen to live by the laws of Torah to be "a light among the nations".
Jews highly value education. Traditional Jews will not move to areas where there are no schools. Chess, as an intellectual game will be encouraged.
That said, you should not automatically assume any Jew wearing a skullcap is an angel. There are bad apples among Jews, as there are with every other group of people.
There have been several recent forum topics about nationality. For example, "Why are Russians so good at chess?" And "India will provide 30-40% of world's top chess players in next ten years" which is about a prediction made by CEO and Founder of Chessbase Software Frederick Friedel. There has also been a thread along gender categories titled "Men are better than Women at Chess."
For the observations and hypotheses of the above linked posts and threads, a number of reasonable reasons are proffered: Numerical Advantage and/or Culture.
Now with regards to the numbers of GMs, Elite GMs, and World Champions, there seem to be a large number of players who are either Jewish or of Jewish descent. The most prominent names being Bobby Fischer who's mother is Jewish and Garry Kasparov whose father is Jewish. Other famous Jewish Chessplaying GMs and World Champions are Botvinnik, David Bronstein, Reuben Fine, Viktor Korchnoi, Emmanuel Lasker, Susan, Szofia, and Judit Polgar, Sammy Reshevsky, Akiba Rubenstein, Wilhelm Steinitz, Mikhail Tal, and many others.
Now these players of Jewish descent do not have the numbers, or a high numerical population pool like Russia, China, India, etc.... YET they vastly outperform their population numbers. By far.
Is it culture? If so, what specifically is it about Jewish culture that is so helpful for attaining GM excellence in chess?
Are folks of Jewish descent smarter than other ethnicities, generally speaking? For example, if you look at Nobel Prize winners, many of them are also of Jewish descent.
In the Bible, or the Old Testament, or the Torah, the Hebrews or Israelites or Jewish people are said to be God's Chosen People. Might this partially account for their excellence in Chess?
FWIW, I'm not of Jewish descent. I'm a goy. A Gentile. But I'm making an observation that there is considerable number of Super GMs and World Champions who are Jewish or of Jewish descent that is much, much greater than their population. And I was wondering what might account for this phenomenon. Thoughts?
