Hans Böhm & Yochanan Afek – The Royal Chess Couple in Action. ISBN 9789492510570. 384 pages.
The Royal Chess Couple is a combined attempt to introduce the various traits of the most significant piece with the most powerful piece on the chessboard. Following a short historic review of the development and metamorphoses of each piece over time, the reader is offered 240 positions (480 in total) from tournament practice as well as from the magic world of chess composition. In each position a royal piece plays either a crucial offensive or defensive role. These positions are subdivided into 60 themes, four positions per theme, arranged by their increasing difficulty. The reader may use the positions as training challenges to improve his understanding and playing skills or just to enjoy playing through them. In either case he will learn to appreciate the characteristic qualities of each piece alone and in collaboration with other pieces.
