In a previous post, we have speculated that two players, Yaakov and Aryeh Zilbershats, had used the Maccabiah merely as a way to get out of Europe in 1935, while being no more than amateur players. Yaakov's grandson, Boaz Zilbershats (his preferred English spelling of the original Polish Zylberszac) had confirmed that this was in fact the case -- and that, in fact, the 1st and 2nd Maccabiahs were notorious for such "cheating". He provided us with much information; inter alia his grandfather's membership in the Maccabi World Union (above), his visa certificate to Palestine, etc.
The Wikipedia article, in Hebrew, notes that those who remained in Palestine as illegal emigrants after the 1935 Maccabiah included, inter alia, the entire Bulgarian brass band, which played in the opening and closing ceremonies... Mr. Zilbershats adds that, while never claiming to be more than amateurs, the two brothers were long-time chess fans, and that there is even a chess team in the Israeli league named after Yaakov Zilbershats, where he (Boaz), as well as his father (Yaakov's son), and two of his own children play.
We are in the process of compiling information on Jewish players who used chess to escape Europe to Palestine in the 1930s. Many have tried, and some failed, as can be seen here.
