Instructional Archived Material

Reader Tom Chivers of the blog http://streathambrixtonchess.blogspot.com/ points out where you can find a free pdf file file (110 pages!) discussing a series of secret training games by Botvinnik.

The pdf file is one of countless archived articles at ChessCafe. You can spend hours and hours perusing these archives. Here are some samples:

• Developing Beginner's Board Vision
  
• 400 Points in 400 Days - Part 1 and Part 2
  
• Olympic Mating Patterns
  
• Opposition Clockwise - nice coverage of King & Pawn endings - Part 1 and Part 2
  

When you have a few minutes (or a few hours), take a look!

And take a look at Tom Chivers' blog, noted above. He's got a lot of good material.
