Perpetual Chess Podcast

Our guest this week is one of the world’s leading experts on chess ratings. Mark Glickman is a senior lecturer on Statistics at Harvard University, from which he completed a Ph.D. in statistics. Mark has been researching and sharing ideas about ratings for decades, and has been the chairman of the US Chess Ratings committee since 1992. He is the inventor of the Glicko and Glicko2 rating systems, versions of which are used on liChess and Chess.com. He is also a USCF Master, and has written and co-written several papers on ratings. In our conversation, we review the history of chess ratings, the efficacy of the “Elo rating system,” rating deflation and other potential issues with the current online and OTB systems. This was a fascinating conversation during which I learned a great deal! More info and shownotes below.  0:00- We begin by discussing how Mark became interested in ratings, and a bit about the history of chess ratings.  Mentioned: Arpad Elo, Kenneth Harkness Bradley-Terry Model, Ernst Zermelo 15:1
