The Ultimate Chess Puzzle Book, by John Emms (2001)

This book provides a wealth of puzzle positions to test just about every facet of your tactical skills. The puzzles in this book have been selected by analysing games new and old in search of original puzzle positions. It is very unlikely that even seasoned solvers will recognise many of these positions. Emms, by allying his skills with those of powerful computers, has also made every effort to ensure that the solutions are sound, and that there are no unmentioned alternative solutions. The book begins with 100 relatively easy positions suitable for novices, and ends with 100 extremely tough puzzles, which provide a mind-bending challenge even for top-class players. There are 1001 puzzles in all.
