"Jewish" style was supposed to focus merely on exploiting the opponents' mistakes. He also praised rival chessplayer Capablanca for taking the world title from "the Jew Lasker". He is reported to have expressed similar views in an interview to the Czech media Svět in 1942. Almost immediately after the liberation of Paris (and before World War II ended), Alekhine publicly stated that "he had to write two chess articles for the Pariser Zeitung before the Germans granted him his exit visa ... Articles which Alekhine claims were purely scientific were rewritten by the Germans, published and made to treat chess from a racial viewpoint." He wrote at least two further disavowals, in an open letter to the organizer of the 1946 London tournament (W. Hatton-Ward) and in his posthumous book ¡Legado!. These three denials are phrased differently. Extensive investigations by Ken Whyld have not yielded conclusive evidence of the authenticity of the articles. Chess writer Jacques Le Monnier claimed in a 1986 issue of Europe Échecs that in 1958 he saw some of Alekhine's notebooks and found, in Alekhine's own handwriting, the exact text of the first antisemitic article, which appeared in Pariser Zeitung on March 18, 1941. In his 1973 book 75 parties d'Alekhine ("75 of Alekhine's games"), however, Le Monnier had written "It will never be known whether Alekhine was behind these articles or whether they were manipulated by the editor of the Pariser Zeitung." British chess historian Edward G. Winter notes that the articles in the Pariser Zeitung misspelled the names of several famous chess masters, which could be interpreted as evidence of forgery or as attempts by Alekhine to signal that he was being forced to write things that he did not believe; but these could simply have been typesetting errors, as Alekhine's handwriting was not easy to read. The articles contained (probably) incorrect claims that Lionel Kieseritzky (Kieseritsky in English, Kizierycki in Polish) was a Polish Jew, although Kieseritzky was neither Polish nor Jewish. Winter concludes: "Although, as things stand, it is difficult to construct much of a defence for Alekhine, only the discovery of the articles in his own handwriting will settle the matter beyond all doubt." Under French copyright law, Alekhine's notebooks did not enter the public domain until January 1, 2017. There is evidence that Alekhine was not antisemitic in his personal or chess relationships with Jews. In June 1919, he was
