Boris Gulko is one of the most distinguished Grandmasters in the chess world. He's a former Soviet Champion and has also won the U.S. Championship twice since his immigration in 1986, making him the only chess player ever to have held both the American and Soviet championship titles. Dr. Joel R. Sneed is a professor of psychology at Queens College of the City University of New York, an amateur chess enthusiast and a student of Boris Gulko's.
Lessons with a Grandmaster III is an excellent resource to gain the insight of a grandmaster. GM Gulko and Dr. Sneed explore high-level strategic ideas in a way that is understandable to the average chess player. Treating each game as a series of exercises makes the book more interactive than most game collections, which I think is the ideal way to learn. -- Vanessa West Chess Life
