This book provides a repertoire for Black with the ever-popular Queen's Gambit Declined. Opening expert John Cox covers not one but two key options for Black. The Tartakower Variation is a sophisticated defence used successfully by world champions such as Kasparov, Karpov and Kramnik. The Lasker Variation is an easy-to-learn and reliable option devised by one of the legends of the game. Cox also demonstrates how to play against White's other tries, including the Exchange Variation and Bf4 lines. He explains in detail the typical plans and tactics adopted by both sides, whilst also tackling the tricky subject of move-order possibilities. *A repertoire for Black against the Queen's Gambit *Provides answers to all of White's main options *Ideal for improvers, club players and tournament players.
