This book outlines two fundamentally different ways for White to attack the Modern Benoni Defense. The author shows that one of these, Taimanov's 7 f4 and 8 Bb5, may even be an outright refutation of the modern Benoni, especially with the follow up 8...Nfd7 9 a4!. The other system outlined, the Knight's Tour, may be used not only versus the traditional 1 d4 Nf6 2 c4 c5, but also against other move orders which are appearing ever more frequently on the chess scene, such as 1 d4 Nf6 2 c4 e6 3 Nf3 c5 and 1 d4 Nf6 2 Nf3 e6 3 c4 c5.
