I enjoyed going through it; fabricated or not!
French Defense: Grigoriev Variation

"Alekhine himself gave this game in his book MY BEST GAMES, in fact, although it was originally really only an annotation by him to his game with Grigoriev in 1915 (Alekhine was Black) showing the variation that he *would* *have* played (as Black) if White had played 11. gxh4 instead of 11. O-O-O. 11 castling in fact also led Grigoriev into a lost game with resignation on move 26."
ASM Dickins & H Ebert, "100 Classics of the Chessboard"
I came across this attacking game of Alekhine V/s NN where he had 3 Queens to crush the Opponent's King. As the opponent also had 2 Queens, both the King's were lucky to play with them.
This must be the only game on record which has 5 Queens fiercely covering ground on board.
