I would like this question to be Community Wiki because I hope to collect several answers.
Can you name famous games where part of the fame comes from the circumstances surrounding the game? I hope it is clear that this is not really a subjective question. Which games are selected will depend on people's preference, but for each answer it will be clear cut whether the game has a famous story or not.
To get the ball rolling, let me mention the following (if this question is liked, I will edit it to list all answers with (if possible) a link to the game:
- Tal - Benko, Belgrad 1959: Benko wore sunglasses to "avoid being hypnotized" by Tal.
- J. Polgar - W. Browne?: Polgar used to bring a teddy bear to the chess table. In this game, Browne (I think) took a toy cannon, aimed it at the bear, and started the game... which he won.
- Steinitz - Bardeleben, Hastings 1895: Steinitz's last move reached a position in which he had a forced mate in 10. Bardeleben left the tournament hall without finishing the game. Legend has it tat he did not want to allow Steinitz the pleasure of reaching the mate, but it seems that he left because of noise and did let Steinitz know.
