I started this book months ago, read various other books in the meantime and came back to this one. The book has 50 checkmate patterns, each one with multiple variations. I study each one to make sure I understand it, before I go on to the next one. So, it’s slow going. (I’m up to number 41 now.)

At the end, there’s a test with 36 puzzles. You’re supposed to find a way to get checkmate (or take major pieces of your opponent’s) without referring back to the patterns in the main section of the book. I’m not sure how well I’ll do.
