This week's episode of the New In Chess Podcast features a narration from "The Essential Sosonko", a collection of chess portraits based on personal stories authored by chess grandmaster Genna Sosonko. The subject of this week's episode is Latvian chess master and trainer Alexander Koblenz.

A four-time Latvian national champion, Alexander Koblenz (1916-1993) is best known as the coach of another, more famous Latvian: the eighth World Chess Champion, Mikhail Tal. Born into a prosperous Jewish family, Koblenz discovered at an early age that his profession would deviate from the well-trodden path laid out for him by his parents. At the age of nineteen, he began writing his first chess book, a hobby he would maintain for the rest of his life. There was also tremendous hardship: his mother and sister perished in World War II, and the annexation of Latvia by the Soviet Union brought its own set of challenges.
