"A two-volume work by the renowned author Mihail Marin, who is noted for his ability to clearly explain complex material. The first volume is primarily devoted to the position arising after 1.d4 f5 2.c4 Nf6 3.g3 g6 4.Bg2 Bg7 5.Nf3 0-0 6.0-0 d6 7.
Nc3 Qe8, with Black aiming to achieve .e5 - Marin explains Black's strategic aims quite well in his lengthy introduction. Should he do so the second player will often reach a very good version of the King's Indian. That the Leningrad happens to have much less theory than the K.I.D. is a bonus. Those looking for an all-purpose answer to all of White's major opening tries besides 1.
e4 will find a repertoire based on the Leningrad Dutch fits the bill. Mihail Marin's two volume series is the definitive guide." -- IM John Donaldson.
