Max Euwe's book Chess Master vs. Chess Amateur


I bought this book several years ago (a German edition of 1962), and I began to read it again to hear what an ex-world champion has to say about opening principles, and how to explore tactical and strategical mistakes of weak players. The book is great, the games interesting. In the second book, Euwe analyses games from stronger amateurs against experts. I guess that some or perhaps most of these games were played by Euwe, but I am not sure.
