We know that Rook endgames are very difficult as there exist huge theory plus methods of the play sometimes are quite difficult even for grandmasters.
Great trainer, late Mark Dvoretzky, made great books on endgames – Endgames University plus Tragicomedies in the Endgames. He analyzed one my interesting game many years ago. I disagreed with him, as my way was possible, too.
Mark agreed, but his analysis went to be used in few other books and articles. Now I’ll try to make some review of thus typical endgame.
