Passage: 5... b5 6. Bb3 Nxd4 7. Nxd4 exd4 8. Qxd4??Alexander Alekhine recommended this move in the tournament book for New York 1924 as a means for White to draw, but it is a mistake that loses material. White should instead play 8.Bd5 or try a gambit with 8.c3.

Question: Who suggested a move to White, only to later understand that it is fallacious?
Alexander Alekhine
