Book excerpt: The Leningrad System of the Dutch Defence is an interesting hybrid of the Dutch and the King's Indian. For many years, it was viewed with some suspicion in view of the slight positional weaknesses created in Black's position. However, in the 1980s dynamic new approaches were introduced by such players as Sergei Dolmatov, Evgeny Bareev, Mikhail Gurevich and especially Vladimir Malaniuk. These players showed how an active approach could compensate for these defects, and offer Black excellent winning chances. Since then, the Leningrad has been a popular and effective opening choice for players of all levels.
