I am not into chess, but The Queen’s Gambit revealed its interesting world, and something got stuck into my mind.
As shown by this article the movie had to make compromises, especially when depicting the tournaments which have quite strict rules, thus making them very boring for the commercial movie consumers.
The last match was so long that it required an overnight break. During this break, the players consulted with their teams and the movie suggests that Beth winning was partially influenced by this help. Is this possible in real-life tournaments?
I tried finding an answer, but only got this Quora discussion which suggests that long (overnight) breaks during tournaments are something very rare today.
