Recent Analytical Finds Purchases from our chess shop help keep ChessCafe.com freely The third edition of my Endgame Manual is now available. The new text accessible: contains a number of clarifications and additions based on recent analytical finds. This month I would like to tell you about some of the most interesting changes.

Of course, it is reflected in the new edition of my Manual, but, as Karsten Müller already wrote about it in his February 2011 column, there's no point in reproducing the same analyses Mark Dvoretsky Endgame Manual CD again in this article. by Mark Dvoretsky In exactly the same way I'll just mention the recently-discovered mistakes in the classic ending with opposite-colored bishops from the game Euwe- Yanofsky (Groningen, 1946) – Müller talked about these in his August 2010 Translate this page column. I like endgame positions with an unapparent and only solution. They can be used as exercises in coaching work. The strong aesthetic impression they make on students helps them to more deeply understand the plans, evaluations, and technical methods that are hidden behind the variations and remember them more confidently.
