"Python Strategy is undoubtedly the new standard work on the 'defensive artist' Petrosian. Even 31 years after his death and in the era of engines, Petrosian's games, analysis and verbal explanations provide valuable advice for every chessplayer."
Alexander Hilverda, SCHACH "What is it about the book that I loved so much? The annotations by Petrosian were usually done immediately ... Read moreafter his game had ended for magazines or newspapers. This meant that his annotations were mainly word based with the inclusion of deep variations only when required. Such kind of annotations may not be perfect (like computer analysis) but they teach you a lot about the game. It's like getting to peek into the mind of a great player… This book helps you to not only know about one of the greatest legends of the game but in doing so you will unknowing experience a sudden rise in your positional understanding."
IM Sagar Shah  "Five recent offerings from Quality Chess confirm that it is the unquestioned leader when it comes to consistently publishing chess books of the highest quality… Python Strategy, which contains numerous interviews of Petrosian, has over 100 deeply annotated games… Those looking for insights into the mind one of the most original World Champions of all time will find Python Strategy a fitting tribute and an excellent value."
IM John Donaldson, Chess Today "This book contains a significant amount of explanation of the thought process of the author, his game analytical skills, his profound thinking of the game… The author has made it a point to include some experience or narration necessary before each chapter. This gives the readers clear insights into what the 9th world champion thought at that time… This is such a wonderful book, that I recommend it to everyone."
Chessarticle blog "Python Strategy is a collection of narrative and entertaining content on the life and games of tenth world champion Tigran Petrosian… This work is recommended for the chess friend who likes to see well-commented games for entertainment as well as to improve his playing strength, as well as for those who would like to learn more about the former world champion."
Uwe Bekemann "It is beyond doubt that Tigran Vartanovich Petrosian (1929-1984) belongs to the very greatest part of chess history… The title Python Strategy is not a literal translation of the Russian title, but is based on a comment by Euwe that many opponents of Petrosian's chess must have felt like the strangled victims of the python."
