Query: Fantastic.

I'm most of the way done with another checkmate chessercises book, so I had to learn many of these mates the hard way. But even with my experience solving many types of mates in 5, this book has much more to teach me.It introduces each mate by name, gives examples of what it can look like and how it can come about, then it has about 3 games ending with that kind of mate. The games are annotated, so you get some chess strategy for free with this book.Finally, each section ends with some exercises.Do not worry about the small size of the book. That just means it is concise, so you can learn it fast instead of wading though pages and pages of paragraphs like in some other books. Get straight to exercising.
