How does the author use symbolism in the novel, The Yiddish Policemen’s Union?

The author uses the game of chess to symbolize the obstacles—both external and self-imposed—that one must face in life. Chess is often framed as an analog for characters’ respective experiences of life. For example, Landsman’s neurotic father is described as having always played chess with a highly neurotic and pained air. Another example would be the impossible chess problem that Mendel places on his table in the Zamenhof before he dies, signifying the idea that Mendel has no beneficial or advantageous moves left in his life.
