Non-attacking chess pieces (PDF, 14 MB) - sixth edition, 795 pages, over 500 formulas, many tables, published Feb 02 2013 (minor update Mar 29 2016). A book is devoted to the question of the number of arrangements of non-attacking chess pieces of the same kind on chessboards of various sizes and types. The best-known example is the n-Queens problem, but this publication has a much wider range and includes other chess pieces (kings, rooks, bishops, knights) and many fairy pieces. Even though the book is about chess and each problem can be placed among chess-mathematical problems, it will be more readily understandable by mathematicians than by chess players or composers. A partial knowledge of linear algebra, difference equations, generating functions and power series is necessary.
