Extra Notes:

1) Games where Alekhine gave the wrong score

-Flamberg improved ending
In Shakhmatny Vestnik in 1915, Alekhine gave the final moves as 36...Qb4! 37.Rc7 Ba4 38.Qf1 Bb5 39.Qd1 Qa4!. Source: Andy Soltis "Chess Lists", 2nd edition, McFarland Publishing, 2002

-Alekhine vs J H Morrison, 1923 - improved ending Chessgames has the correct game score. Alekhine annotating in La Nacion (1929) "improved" his play with 22.Be4 Nh8 23.Rxg7+ Nxg7 24.Qh7+ Kf7 25.g6+ Ke8 26.Bxd6. He repeated the line in "Auf dem Weg zur Weltmeisterschaft 1923-1927" (Berlin/Leipzig, De Gruyter, 1932) Source: Andy Soltis "Chess Lists"

-Mieses vs Alekhine, 1914 - an omission
ChessGames has the correct score. "Also at Mannheim Alekhine won a 50-move game from Jacques Mieses - but he omitted the final 15 moves in My Best Games, 1908-1923, making it seem that his quiet 35th move stunned his opponent into resignation." Source:(Andy Soltis, Alekhine's 15 "Improvements", Chess Lists)

-Reti vs Alekhine 1925 - AA's 40 move version.
Edward Winter's Chess Note 6358 points out that Reti annotated a 42 move score only two days after he played the game. The tournament book agrees with Reti giving the repetition 18 Bg2 Bh3 19 Bf3 Bg4 20 Bg2 Bh3 21 Bf3 Bg4. Reti reports that Alekhine offered a draw here, but he declined and continued 22 Bh1 h5 etc. Apparently, Alekhine could not bear to have his masterpiece marred by including what was an obvious offer to draw by repetition. He also fails to mention that he verbally offered a draw at 21...Bg4. Well, how could he? He had eliminated the move from his score entirely.

2) Bogus Games not due to Alekhine

-Alekhine vs A Muñoz, 1945 - Just an analysis of Alekhine/Frank vs Bogoljubov/Pfaffenroth, 1941 See "Mysteries at Sabadell, 1945" http://www.chesshistory.com/winter/...

-Alekhine vs Nenarokov, 1907 - This score was a fraud perpetrated by "Grigory Bogunovich" of Pittsburg, Pa who sent it in to Chess Review (September 1959, p257) along with a clearly ridiculous story about the encounter. Note that it appeared shortly after Tolush-Aronson which is the real game.

3) Games with serious questions (not proven to be frauds)

-Rodzynski Game
Questions 1) The game is dated 10 Sept 1913, but wasn't published until 1922 in La Nation Belge. Why? 2) The game is listed a an Exhibition game. "J Rodzynski" is given in Skinner & Verhoeven, game 297, page 87. He was an amateur who entered a Café de la Régence tournament in 1917. He finished 10th out of 16 (Aurbach was 1st). Why would Alekhine play an exhibition against a lesser player like Rodzynski?

-Gonssiorovsky Game
Alyehkie claimed it was one of six blindfolded in Odessa 1918. No one, however has found a record of that exhibition. If Alyehkin played Black blindfold, wouldn't it be noted somewhere? Boris Verlinsky who was in Odessa in 1918 said Alyehkin played an impressive Queen sac against Gonssiorovsky, but in 1912. Originally published by Alekhine in the booklet "Das Schachleben in Sowjet-Rußland" (1922).

-The Feldt game
Alekhine dated the game in 1918. Skinner & Verhoeven cite the original publication of the game in Moskovskiya Vedomosti on 3 December 1916 (Gregorian calendar). Supposedly, the game was played by a certain Dr. Martin Fischer, not Von Feldt. This is according to Leon Stolcenberg, a former resident of Tarnapol who moved to Detroit Michigan. He told the story in Chess Life, 5 Oct 1951. Stolcenberg was a master himself and claimed to have witnessed the blindfold exhibition. I don't know if he claimed to witness these exact moves or not. Black's obliging play, the bad date and bad opponent name add up to a very suspicious game.

-The Supico "game"
Verhoeven & Skinner cite "Chess 1941 v6 p167-168" as the earliest publication date. Alekhine's activities from mid May to late August are undocumented. Only two known games are from this period. This simul is completely unknown. The number of boards, wins etc. are unknown, probably because it never happened. In "Chess: More Miniature Games" (1953) by J. Du Mont, game 55, Du Mont gives "Alekhine-Supiko played in the U.S.S.R., 1919."
