A comprehensive book from the Swedish International Master Thomas Engqvist for understanding the most important tactical chess positions in the opening of a game, the middle game and the endgame. It covers other important facets of tactical play, including calculation (how to calculate with the help of stepping stones), attacking play such as defence and counter attack, and even psychological tactics. Each numbered position can be seen as a test-yourself quiz (with answers given below the diagrams) to help cement tactical understanding. IM Thomas Engqvist has been a coach for 30 years.
