Why most of the great chess players are jews?

Maybe that is something worth investigating? Is it any coincidence that Jews have the highest IQ on average yet have all of these accomplishments? Film and banking at the turn of the century were considered crass by the WASP elite, so Jews naturally went into these fields as they were socially looked down on and had no problem with such fields (why would they? Film and banking aren't objectively wrong in and of themselves)
So many Jews passed elite college entrance exams that Harvard, Princeton, and Yale started having subjective criteria such as "character" (read: arbitrary qualities relating to upper class whites) to deal with their so-called "Jewish problem".
The Jewish community overthrew the white shoe boys' stranglehold over the legal profession.
Israel, only founded in 1948 and roughly the size of New Jersey, has so many accomplishments such as net gain in trees, great pharmaceutical, medical, and computer tech advancements, the only liberal democracy in the area, and even builds schools and hospitals for the Palestinians.

Question: What is common among Kasparov, Fischer, Tal, Polgar, Botvinnik, Lasker, Korchnoi,Smyslov, Aronian and Gelfand?
Answer: They are either jew or half jew.
Is there any relationship between genes and chess talent?
Well, I am not a jew.

Fischer was not a jew.

Fischer was not a jew.
Both of his parents had Jewish descent.
So religion is in the genes and not subject of free choice?
Also naming 10 players and then concluding that's "most of the great chess players" is kinda gimmicky. I'd guess the list of non-jewish "great chess players" would probably exceed this by far.

Hmm this is the first I see about this.

Except for banking.

So what about Alekhine, Carlson, Karpov, Capablanca, Morphy, Kramnik, Anand, Spassky, Botvinnik, Steinitz, and dozens of other non-Jewish great chess players throughout history?

You are confused. You can be of jewish descent, and also an atheist, buddhist, muslim, or whatever. You can even be an antisemite, like Fischer was.
I am confused because you confused me! ^^
I assumed the point of your previous post was to confirm he was because his parents where but now it sounds quite the opposite.

Chess is a heliolithic game and the Jewish culture is heliolithic thus chess appeals to people who were brought up in the Jewish culture. But, of course, there are many great chess players who are not Jewish at all. Also many people who are labelled as "Jews," while being of Jewish descent do not believe in Judaism, Many are atheists, Christians, Buddhists and so foth. Many people who we think of as "Jews" are not descended from the original tribes of Israel. At one time Jews proselytized and many people who call themselves "Jews" are actually of European descent.

And it's not true that 'most of the GMs are Jews, as by their religion and/or ancestry', but it would be more interesting to ask why so many Jews became Nobel prize laureates, if they just represent a tiny fraction of the entire world population. Jews seem to be, on average, pretty bright people.

Well, i find this an interesting question. My answer is that there are a number of factors that contribute, but my answer is not scientifically supported :
1) jews were discriminated by all other religions and were never allowed to own property in europe or become members of a guild like butchers or leatherworkers. Christianity did not allow lending and neither did islam, so jews were the natural community to take up this activity, which became over time the biggest success in history. So they were office workers and naturally inclined to play games that the average butcher did not play.
2) they are studious and are called : the people of the books. They like to develop thinking systems and play with them. Like the kabalah.. Chess is such a system.
3) they are a tight community and chess is very much a community game
4) they are highly competitive and like intellectual challenges
5) they are smart and people like einstein are proof of this.
0.2% of the world population being Jewish it is interesting that not only the World Champion has been Jewish most of the time, but also that many of the strongest players not to win the title have been at least partly Jewish, like Rubinstein, Tarrasch, Zukertort, Bronstein, Reshevsky, Najdorf, Nimzowitsch, Spielmann, Fine, Korchnoi, Gelfand, Aronian, etc.
