In Volume 1 Kornev's choice of arms against 1.d4 d5 2.c4 is one of the most popular openings in modern chess practice - the Slav Defence. Besides, he considers in detail how to meet opening set-ups where after 1.d4 d5 White refrains from an early c2-c4: 2.Bg5, as well as 2.Nf3 Nf6 3.Bg5 and 2.Nf3 Nf6 3.g3. Another topic is the ever growing in popularity The London System (2.Bf4 and 2.Nf3 Nf6 3.Bf4).
Kornev does not confine himself to dry variations, he also aptly explains the ideas behind them. Thus his book should serve a wide range of players - from club amateurs, up to grandmasters. The Slav-Caro-Kann connection allows Black to sidestep many opening variations. For example, after 1.d4 d5 2.Nc3 he simply goes 2...c6, avoiding the main line of the Veresov System which arise after 2...Nf6 3.Bg5. In the London System after 1.d4 d5 2.Bf4 c5 3.e3, Black could directly exchange on d4 - 3...cxd4 4.exd4, obtaining a harmless sideline of the Caro-Kann - 1.e4 c6 2.d4 d5 3.exd5 cxd5 4.Bf4.
