This is a great little book. As with all pre-computer age books, some of the analysis is a little off, but since the lessons are positional in nature, that doesn't matter and it really stands the test of time. The games and positions are very instructive and the writing is humorous and easy-going. The translation is, again, a product of it's age. Some of the wording seems slightly off, but nothing that detracts from the lessons.
I read this book by transcribing the games, positions and key elements of the text into a modern database, and people really should not think that the descriptive notation is a problem if you are really studying a book. If you are going over every move and every position and every comment, the notation is irrelevant.
I have to say that I ignored Reinfeld's problems stuck on at the end, so as far as I'm concerned, the book is 90 pages long with some silly problems added by an editor.
The book would be even more marketable if someone re-edited it, cleaned up the translation and transcribed it into algebraic - but it would not be more instructive.
Books like this and "Simple Chess" by Stean are models of concise instruction on positional chess. I can highly recommend them to any improving player.
