I know that I have mentioned GM Nigel Davies website "The Chess Improver" at least in passing on this blog, but I wanted to specifically encourage Readers to stop by and enjoy the varied and always informative content that he has assembled. Recently video clips from the BBC program The Master Game have been posted: interesting, top-level chess with comments by the players themselves. Great stuff!
I have also enjoyed Davies' books, and this link will take you to a number of reviews.
(One last thing: "The Chess Improver" contains a link to this blog; but, of course...)
