He should have been an excellent International Master by now.' Persitz studied economics and became a well-known financial analyst and had several long-standing fights with the Israeli Chess Association's administration. He once sent a letter to the ICA which began, "Dear honorable gangsters, ...".
He was known not only for his natural talent, but for his for his excellent written analysis anf was a long time contributor to the British Chess Magazine's 'The Student Corner'. In addition he authored three chess books in Hebrew.
