If in a real life Chess tournament between grandmasters, a person in the crowd shouted a winning move to one of the players, and the player had not realized they could make that move and then proceeded to win thanks to the advice, what would happen?
FIDE Laws of Chess
https://handbook.fide.com/chapter/E012018 :
11.3.1 During play the players are forbidden to use any notes, sources of information
or advice, or analyse any game on another chessboard. [italics mine]
12.7 ... Players in other games must not to speak about or otherwise interfere in a game. Spectators are not allowed to interfere in a game. The arbiter may expel offenders from the playing venue.
12.9 Options available to the arbiter concerning penalties:
...
12.9.6 declaring the game to be lost by the offending player...
So if it's an egregious case where the player contravenes rule 11.3.1 by using advice shouted out by a spectator, and it's that exact advice wihch directly leads to the win, it would be reasonable for the arbiter to give the win to the other player instead.
