70 Intriguing Retrograde Puzzles for the Chess Detective
Written by local St. Louis author, William Murden
Put your detective skills to the test in this original collection of retrograde chess problems. Unlike a typical game, you won't be trying to predict the future, but rather, deducing the past.
Join Sherlock Holmes and Dr. Watson as they investigate 70 unique chess puzzles. Each puzzle challenges you to figure out what must have happened, from the last move played to whether a player can still castle. The problems get progressively more complex, introducing unusual rules and ambiguous board states.
Perfect for anyone with a basic knowledge of chess, this book is for fans of chess, logic puzzles, or Sherlock Holmes.
