The Queen's Gambit is one of the great classical openings. All the world champions and elite players have played this opening - most of them for both sides. In this book the highly experienced coach international master Andrew Martin explains the basic ideas behind all the different variations you can encounter after 1 d4 d5 2 c4. This includes the classical defences (such as the Orthodox, the Lasker and the Slav) as well as the weird and wonderful (such as the Albin Counter-Gambit, the Hennig-Schara Gambit and Marshall's Defence).
