In addition to blogging and giving lessons (please contact me if you're interested!) I also record videos for ChessLecture.com. The topics have often been diverse, but I did a series on the world champions, presenting two games by each, with an eye to showing not only the quality of their chess but also how we can learn from their games and even put their ideas to work in our practice. That series has been packaged into a series of three two-disc DVD packages. All the ChessLecture DVD offerings can be found here; if you're only interested in checking out my work here are the direct links:
