In volume 2 Dutch International Master Herman Grooten provides the full coverage of the Queen's Gambit Structures. As usual his instructive material is impressive, explaining in detail all possible plans for White and Black, making this book indispensable if you want to understand these typical structures or play this opening. The concept is extremely attractive to amateur players: whatever your strength, it carries the promise of learning or revising some general strategic knowledge in an easy way.
