Query: Simply the best

It's hard to praise this book too much. The games are exciting, the notes lucid and instructive, not weighted down with mechanically generated variations. (As Hubner's and Nunn's are, for example.) I've played through these games at least once a year since I was a B-player. As a master, I still learn a little more each time. There are some game collections which equal Alekhine's -- Botvinnik, Tal, the orginal edition Fischer -- but none surpass it.
