This is an extremely hard to find chess instruction book. It is titled Checkmate University: The Book of Chess Exercises 1: For K-6 Children. This is absolutely the best chess instruction/learning/practice guide I have ever come by. It is intended for children K-6 but for serious chess players. This is not a teach you what the pieces are and how they’re allowed to move book. This is to teach and practice strategies, capturing, checkmating, seeing tactics and playing tactics. The book is in solid condition with noticeable wear from storage and handling. There is some light staining at the top of the book from what appears to be maybe a coffee spill or something along those lines. The book is 100% solid, usable and legible. There is no mold or moisture present. Please reference the photos for exact condition and feel free to message me with any questions.
