Part 3 offers a compact repertoire against other first moves by White except for 1.e4, including the mainstream Réti and English Openings, and less-common openings such as Bird’s and Larsen’s Openings, and even the Grob (1.g4)! Here, Prusikin offers suggestions that complement the rest of the repertoire, and this means using 1…d5 whenever possible, except for against 1.b4, where he recommends 1…e5. Part 2 covers the detailed theory of the Queen’s Gambit Declined, including the Catalan, and this part complements the general discussion in Part 1. The Tartakower is a very solid variation that was a particular favorite of former world champions Spassky and Karpov, and it is still used by top players. The first part discusses the key ideas and pawn structures of the Exchange Variation and the Tartakower Variation (3.Nc3 Be7 4.Nf3 5.Bg5 h6). Credit: Chess training – Michael Prusikin
