Calculate Like Champions is the third book in the series The Power of Tactics. In this third volume, the authors continue to develop their ideas from the first two books — Tactics According to Smyslov and the Become a Tactical Wizard — where they explain that in chess there are four main tactical elements (check, pin, double attack and unprotected pieces).

They have added very instructive exercises revolving around mating attacks and queen sacrifices to achieve different goals and, in my opinion an extremely important element, defensive tactics.
