A hybrid of the Queen's Gambit and the Nimzo-Indian Defence, the Ragozin featured in a famous book by Soviet theoretician Lipnitsky in the 1950s. Bobby Fischer decided to learn Russian to be able to read that work and immediately afterwards started playing the Ragozin.In recent years the Ragozin has had a tremendous revival and is now being used at top level by players like Vladimir Kramnik, Levon Aronian and Vasily Ivanchuk. In this book, the first monograph on this important system, acclaimed chess author Vladimir Barsky provides a comprehensive coverage of themes and variations, both for Black and for White.For the first time in history, amateur players can acquaint themselves with the important Ragozin System and start playing this flexible opening with confidence.
