I am working through a book that had been collecting dust on my shelf for a few years. Nikolay Minev, A Practical Guide to Rook Endgames (2004) offers an informative discussion of tactical elements and strategic elements in the first chapter, which comprises half of the book. The tactical elements listed are skewer, double attacks, pinning, deflection, far-advanced pawns, and stalemate. He describes each of these elements in simple terms and then with reference to rook endings from actual play.
This position is the last one in the section on skewer. It occurred in Vasiukov -- Dzindzichashvili, Soviet Championship 1972.
Scholastic players and parents: The label "Problem of the Week" links to posts that contain my "lesson of the week." These blog posts serve to reinforce what is presented in my after school and in-school chess clubs.
I am available for one-on-one lessons in person or online. Use the contact form below if interested.
