The Complete Manual of Positional Chess

This book contains a whole lot of positional concepts as well as tactics to master in the middle game.

The book is a little bit miss-titled, some of the chapters are on tactics, it's also basically an encyclopedia on positional concepts but it is more fun. It is not as dry as an encyclopedia.
