Daniel King's 'Power Play' series is one of ChessBase's most popular FritzTrainer course collections. Between 2007 and 2020, an impressive 28 volumes were published in the series, covering not only general topics such as tactics, attacking play and endgames, but also opening repertoires for both Black and White. Jochen Schwarz, a club player from Bremen, has known and valued the Power Play courses for many years and provides an overview of the individual volumes.
