Key Concepts of Chess Volume 1 The Hedgehog by Herman Grooten

pThis is the first volume of the new series ampquotKey Concepts of Chessampquot. The idea is to deal with middlegames in which a certain structure or essential theme becomes central. The idea of starting this series is in line with the ampquotUnderstanding before Movingampquot series because the aim is to improve the understanding of club chess players.
