Welcome to another Adult Improver Edition of Perpetual Chess. My guest is Martin Justesen, who is a 34 year, Denmark-based father of 3. He works as an archivist in the Library of the Danish Parliament, but devotes a lot of his free time to chess improvement and chess-related projects. His efforts have paid off, as Martin has gained a few hundred points in the past years. Prior to the pandemic, Martin had ended a long plateau, as his Danish rating went from 1600 to 1820. During the covid shutdown, he has seen continued improvement, his Lichess classical rating is now up to 2200! In our interview, Martin reveals what he thinks to be the key contributors to his improvement success. Martin is also a blogger,  and has recently released a great new book called, Blindfold Endgame Visualization: 50 Chess Positions. We also discuss how Martin decided to take on this project and why we think that it’s an important study tool.
