Improve your Rook And Knight Endgames

My Rook and Knight Endgames - Strategy and Tactics (now also available in paperback format) book looks at endings with rook + knight Vs. rook + knight. This material balance occurs quite frequently in tournaments, and some classical ideas and endgames have become well-known. Nonetheless, there is some lack of discussion of this topic in chess literature. The book covers both the strategic themes, and gives the reader a chance to practice their tactical skills. Mikhail Botvinnik was well known for his great technique in this type of endings; the book includes several relatively unknown examples from his career to illustrate the typical ideas, but also games by other famous players such as Korchnoi, Morozevich and Anand are featured.
Here are some examples of positions that the reader would get a better understanding of by working through this book.

18. Bc5
A lot has been written about this move in different books. In this famous position Black suffers from weak light squares and lack of space. Petrosian found a brilliant way to consolidate his positional advantage... I mainly see the explanation in the common strategic idea of trading off bad bishop which protects good pawns. Now the pawn chain 'e5-f6-g5' becomes much more vulnerable. Also the white knight's domination over his black colleague becomes more apparent, as now the white knight can access an important 'c5' square.

With the pseudo sacrifice not only has White regained the pawn, but he also achieved a knight endgame, which is winning for him due to the dangerous 'a' pawn, and more active placement of pieces.

Chess Strategy and Tactics: Ebook about rook and knight endgames

I added a new ebook to my list of my publications, this one is called "Rook and Knight Endgames - Strategy and Tactics".

This ebook is a follow up to my ebook about endings with each side having a rook and a bishop of opposite color - Bishop endgames - Do the opposites Attract?. The idea behind these series is the approach that Nimzowitsch used to call "a radioactive method" - selecting a rather narrow topic, and by learning a lot about it, understand chess much better in general. This time I would like to look at endings with rook + knight Vs. rook + knight. This material balance is also a quite frequent guest in tournaments, and some classical ideas and endgames have become well-known. Nonetheless, there is some lack of discussion of this topic in chess literature. Mikhail Botvinnik was well known for his great technique in this type of endings, and I would strongly recommend to the reader to study two famous endgames Botvinnik-Alekhine 1938, and Botvinnik-Levenfish, 1937. Instead of these, I included several less known examples from his career. Also games by other famous players such as Korchnoi, Morozevich and Anand are featured.
