This book completes the trilogy starting with "My Best Games of Chess 1908-1923" by Alexander Alekhine ISBN 0923891498 and followed by "My Best Games of Chess 1924-1937" by Alexander Alekhine ISBN 4871878260. This is a reprint of the original third book, with all of the games converted into Algebraic Figurine PGN Notation with diagrams in the back. Alekhine died in 1946, so this third volume was edited by International Master and British Chess Champion Conel Hugh O'Donel Alexander, based in part on the notes left by Alekhine to some of the games. Alexander Alexandrovich Alekhine (1892-1946) was not only one of the strongest and most original chess players who ever lived, but he was also the most controversial, second only to Bobby Fischer. Everything about his life and death was controversial and is still being written about even today, although he died in 1946, which is 64 years ago.

Fred Reinfeld found that there were many great games by Alekhine that had not been included in the standard volumes. He set about collecting and going though these games. He found 102 interesting and exciting games not found in the other volumes. So he called it "The Unknown Alekhine."
