Calculate like Champions is the final book in the Power of tactics trilogy by GM Adrian Mikhalchishin and IM Tadej Sakelsek.

"In this book, the authors continue to develop their idea from the first two volumes where they explored the most important feature of chess through the eyes of a great Champion, Vassily Smyslov. The book is built systematically and includes numerous different ‘test your tactics’ elements, such as simple solutions, win the material, tactics according to Smyslov, make a choice, unexpected opportunity, answer the question, play better than the champions, complicated calculation and practical exercises.
I can heartily recommend this book to all players even up to and including Grandmaster level. You will find joy while solving the puzzles and improving your calculation." - GM Georg Mohr
