The Ragozin Complex
A Guide for White and Black
The Ragozin Complex is a flexible and versatile chess opening system that, despite its popularity, rarely has been a subject of serious study in chess literature. 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.
