Beginner or expert, this remarkable book of exercises can help you learn chess tactics--the bread and butter of successful play. I own this book in hard copy--a massive boat anchor--and as soon as I found it in Kindle format. The convenience is incredible--the print form sits on my shelf of chess books, unused, but this is getting full use.
Do understand that it's a perfect book for the beginner, since the "mate in 1" problems will help the novice to understand both simple and quite sophisticated piece moves. Learn the piece moves, and immediately begin to see and solve fundamental chess problems...a fun and practical way for the beginner to learn the essentials of piece placement, critical squares, and the full range of tactical moves for success. The more difficult problems will challenge club, expert, and even master-level players, so you can benefit from this book at whatever level you achieve. At $3, this is indispensible.
