Genna Sosonko, in his book
Russian Silhouettes, echoes the thoughts of some grandmasters who knew him, and they speak of a man of integrity and independence, who never complained about his difficult living conditions.
Boris Spassky encountered him in a Moscow subway, just days before his death. Levenfish, who had a wretched look, was clutching a handkerchief to his mouth and declared that he had just had six teeth extracted.
Vasily Smyslov recounts the time that Levenfish visited him, towards the end of his life, armed with a huge pile of papers. It turned out to be a manuscript detailing his lifetime work on rook
endgames. He asked Smyslov to check for errors, and some minor corrections later, the book was published (1957) bearing both names, under the title
Teoriya ladeynykh okonchaniy ("The theory of rook endings"), later published in English in 1971 under the title
Rook Endings. Smyslov freely admits that all of the hard work was carried out by his co-author. In his time, Levenfish also wrote books for beginners and edited a collaborative effort on
chess openings, titled
Sovremenny debyut ("Modern openings"). His posthumously published autobiography,
Izbrannye partii i vospominaniya (1967), contained 79 annotated games. Regarding his playing abilities, Sosonko points to his deep understanding of the game and a keen eye for brilliantly imaginative moves. He was also an
opening theorist; the
Levenfish Attack, a variation of the
Sicilian Defence, is named after him. == Playing style ==
