Perpetual Chess

I've recently started listening to a high-quality podcast, Perpetual Chess, which has chess improvement as one of its central themes. It's US-based and features both professional and amateur US players - including past US champions such as GM Gata Kamsky and IM Nazi Paikidze - but also has a number of international guests on it at the GM/IM level, including notables such as GM Jonathan Rowson, GM Jacob Aagaard, IM Tania Sachdev, and many more.

What drew me most to it, though, are the "Adult Improver" episodes featuring people who have been making significant progress as adults, at both the Master and Class level. Of course there are a number of other very interesting and relevant interviews at the professional level, and the episode notes give a detailed preview of the topics, which I find very helpful. There should be something useful for any chess enthusiast in the interview list.
