This book is an easier version of Combination Challenge!, also by Lou Hays. It contains 535 one- two- and three-move combinations to solve and teaches a study method for learning to play combinative chess. This is the quickest and easiest way to improve your chess rapidly.
Great if you happen to have this little book handy and are looking for intermediate puzzles in a paper back form. But sometimes its solutions are not always the only solutions or even the best ones. Nowadays there are better versions of such a book.
This is a great book in spite of itself. Its flaws:
-a few of the solutions given are actually not the strongest possible moves (I checked) -the "study method" is pretty laughable. It amounts to "go over this book until you hit a point where you solved each of the problems at least three times" -some of the solutions are longer than "3 move" solutions -the division into themes at times seems more confusing that anything. Some of the themes provide a meaningful hint (e.g.: "knight forks", "back rank"), but others don't seem very helpful. A given problem could easily be in the "overloading" or "deflection" section, for example, and this because there is a "double attack" going on -some of the problems are repeats from the author's more advanced "Combination Challenge!" I have no problem with this, but some people will complain about paying twice for the same material -the title really is a test of the reader's dignity. :) Hays says that the rationale behind the title is that: "It is priced with the junior chessplayer in mind."
Still, 4 stars. This is the only book that I've found that provides a good number of problems aimed at weak-intermediary players. If you're comfortable with basic mating themes and want a book with which to drill, I can't really think of a better bang for your buck.
I bought this in the non-specific charity shop by Well Street market that may not even be a charity shop for 50p as part of my new regime of chess training. I do a page or two of puzzles a day (6-12) and they vary between easyish to really fucking hard. They're all forced checkmates or a win of material rather than positional. The 'Junior' in the title might put people off but it's a great great book. If you can find it, get it.
