"Alekhine is a poet who creates a work of art out of something that would hardly inspire another man to send home a picture post card." - Max Euwe
"Oh! this opponent, this collaborator against his will, whose notion of Beauty always differs from yours and whose means (strength, imagination, technique) are often too limited to help you effectively! What torment, to have your thinking and your phantasy tied down by another person!" - Alexander Alekhine
"The openings consist of Alekhine's games with a few variations." – Source Unknown
"Alekhine is a player I've never really understood; yet, strangely, if you've seen one Alekhine game you've seen them all. He always wanted a superior center; he maneuvered his pieces towards the King's-side, and around the twenty-fifth move began to mate his opponent." – Robert Fischer
"While he was hospitalized (during WW I) after being wounded (a contusion of the spine), he became the strongest blindfold chess player in the world. That's how great this guy was. I mean, when normal people go to the hospital, they are totally sad and in pain. Instead, he devoted himself to blindfold chess and became the best in the world in an extremely short period of time. You have to love this guy." – Terry Crandall (on Alekhine)
