Second, a ChessBase article on that video everyone is talking about concerning chess ratings over time. In fact, I may as well embed the video, as everyone else has.
The article establishes who created the video in the first place. It also explains what EDO is, which some of the earlier articles on the video did NOT do. It's disappointing ChessBase didn't mention Chessmetrics, though, especially given that they used to get publish a fair number of articles from the Chessmetrics creator, Jeff Sonas. You can learn more about EDO Historical Chess Ratings at the EDO site, maintained by EDO creator Ron Edwards. It has the advantage over Chessmetrics in that it has been kept current, and I will add it to the blog roll later today. Still, the article is worth a read as Edwards explains some of the weaknesses of the approach when rating earlier players.
Finally, a problem, because why not? I don't have a source for the following problem, other than that it was submitted to the ICC ProblemBot by user Stormline.
White to move and win
