Sosonko brings genuine delight even to the most demanding readers, from professionals to amateurs or even non-players who are simply interested in chess history as a part of general human culture.

– Garry Kasparov

Sosonko's portrait of Tal is no hagiography and is all the better for that. Beautifully written, heartfelt and moving.

– Daniel King

If you love chess history, or history in general, or if you simply want to know more about some of your chess heroes, this book is a must buy. Beautifully written and rich with amazing content. I give Sosonko's The World Champions I Knew my highest recommendation.

– Jeremy Silman, International Master,author of 'How to Reassess Your Chess'

Sosonko's reminisce of Mikhail Tal, the self-destructive, alcoholic, womanizing, half angel - half devil form the pulsing heart of his latest memoir.

– Dominic Lawson, Standpoint

A wonderful insight to the lives of the World Champions.

– Gary Lane, International Master, CHESS Magazine

Sosonko writes with uncommon grace. His free-form stories speak from the heart, and frame each subject within the context of the times. There is wisdom in his open and honest assessments, and each world champion's story has been told with unusual warmth, insight, and compassion.

– John D. Warth, This title is destined to be a classic..., Chess Club of Southern Indiana

An important addition to what we know about the lives of the world champions. This is chess literature at its very best.
