and  make very good points - and some of the unfortunate replies just strengthen their case. As the article stands right now, it is almost OK, in that it mentions "ethnicity" only at a moment in which it becomes relevant (WWII). At the same time, we should (as usual) remembered that what was relevant then was not how people lived, or how they perceived themselves, but rather how they were classified by others. It is good to make clear that Polish players from all origins had good reasons to stay in Argentina, and did stay. At the same time, a category such as "Gentile" (or "Jew" as opposed to "Gentile", as here) does not belong outside quotation marks - just as the more relevant categories of "Jew" and "Aryan" don't. (Also: if I remember correctly, Tartakower actually was a former Austro-Hungarian officer with a Christian  upbringing; he was at risk because (a) he was a Polish citizen, (b) his parents had been converts, thereby making him a Jew *in Nazi eyes*.) It would be better to say: "Najdorf decided to stay in Argentina (as did many players  particularly those in the Polish team, whether or not they had, like him, Jewish origins)" or simply "Najdorf decided to stay in Argentina (as did many players, both "Aryan" and "non-Aryan")". The page already gives (in footnote 1) his full given names as given on his passport, so it is not as if one of the reasons he would have been a conspicious target is being hidden.
