The Queen's Gambit Accepted (1 d4 d5 2 c4 dxc4) has a long history and has always been popular at all levels of play. However, in the past few years it has undergone an explosion of interest, thanks to many new discoveries of possibilities for very dynamic play from Black. One of these is the line 1 d4 d5 2 c4 dxc4 3 e4 b5!?. This was previously thought to be a very poor line for Black but numerous recent games and investigations have completely changed this assessment. This is now almost the main line of the Queen's Gambit Accepted and there is currently very little theoretical material on it. Nicolas Yap analyses this line in forensic detail and also investigates other popular, counterattacking lines such as 3 e3 e5!?. The book is rounded off with suggestions to meet other White systems that involve 1 d4 but not 2 c4 (such as the London, Colle etc.) This makes the book a complete repertoire to face 1 d4. A complete repertoire for Black to counter 1 d4. The question and answer approach provides an excellent study method.
