Botvinnik's games may not exhibit the clarity of Capablanca / Fischer or the virtuosity of Tal but his thinking, in this book, is very instructive. Botvinnik's annotations demonstrate how to analyse positions and how to find a clear strategic thread in chess games - in doing so Botvinnik shows how hidden resources can be found in seemingly dubious positions e.g. Botvinnik's amazing win, despite two sets of doubled pawns, against Levenfish.

The annotations of Botvinnik are notable in their definitiveness - which contrasts, for example, with the more 'balanced' annotative style of Keres - that some might find dogmatic but which I found helpfully conclusive.
