Known as one of the best coaches of our times, Mark Dvoretsky left us a valuable legacy to help chess players improve their training technique and take that much-awaited leap forward. His books are a great source of inspiration and help for every aspiring chess player. Mark Dvoretsky learned how to play chess before elementary school, but back then he was mostly interested in mathematics, so the game wasn’t given that much importance. He started to take chess seriously and began going to the district’s chess club and studying only when he was in the fifth grade.
