This week’s guest on Perpetual Chess an author, an American Chess Magazine columnist, and the recently-crowned World Champion of correspondence chess, Dr. Jon Edwards. Correspondence chess historically was played by mail, without assistance. These days it is played by email, with engine assistance allowed. The current format makes for incredibly accurate games that often end in draws. So what enabled Jon to win the Championship? Did luck play a role?
Jon is an expert on how modern engines work, and what they say about various openings. We discuss the current opening battlegrounds of top engines, and discuss how correspondence chess has evolved as engines continue to get stronger. Should the rules of correspondence chess be tweaked because so many games end in draws? Among many other topics, we also discuss Jon’s massive chess book and chess stamp collections, and why Petrosian is his favorite player. Please read on for timestamps and links related to topics discussed.
