New In Chess has printed or reprinted the 1941 Absolute Championship won by Botvinnik. In service download websites the games are available.
The games can be found in
USSR Absolute Championship 1941
However I have doubts about the commentary written by Benzol.
I have never read anywhere including in the older English translation of the book that the winner was supposed to play Alekhine.
If I recall Botvinnik complained about the 1940 USSR Championship held in Moscow. Lilientahal and Bondarevsky tied for first place.
The Absolute 1941 was never listed as a USSR Championship.

Alekhine in 1941 was playing on the other side.
One of the problems with the PGN download of the tournament is where did the download come from. Russchess which Google has blocked never offered the 1941 download in the Archives.
Winter a few years back in Chess Archives indicated a problem or mystery of one of the games Keres played. Was f6 or f5 played? Some books have the e.p. Others do not.
The English version in the U.S. was by Dover in the 1960's, and reprinted it appears in the 1970's. Hardinge Simpole Chess Classics reprinted the book 2002. New In Chess version just came out.
The mystery of the Keres game has to be a guess of why it happened.
Possibly from transposing Algebraic or Russian notation to English descriptive.
If you are studying chess, 1941 Absolute is one way to go. Note that Botvinnik included one of the games in his 100 Games. Keres whether the Reinfeld edition, or Keres' own collection of his games also included the 1941.
