The Nimzo and Bogo-Indian Revisited

Most of the lines are positional, not tactical in character. While playing Black, you have to accept that occasionally you will not equalize, or get surprised or out-prepared. Learning the material from this book should sharply limit the extent of such instances, thus improving your overall results. Finally, I have an important piece of advice: remember about color strategy! The Bogo-Indian is mainly based on dark-squared control, while the Nimzo-Indian does so on the light squares. In case you forget what to do, this may prove a very useful guideline when choosing a move.
