Fred Reinfeld's tenth contribution to the annals of chess playing is decidedly geared for the teenager and/or young adult who knows what it's all about. Seventy three provocatives games are pictured here along with accompanying notes that explain the techniques used in completing a full game in twenty moves or less. If the reader's interest is limited to relishing beautiful moves, the left hand page with its layout of the game will suffice. But if he is curious about the underlying ""philosophy"", a careful study of the notes will be amply rewarding. The opening paragraph tells a little about each game and the expert closely affiliated with it. A definite challenge here for the aficionado.
