There are the FIDE Rules for Chess. This for different types of chess. Are there also official rules for Simultaneous exhibition chess? Where can I find them?
I don't think FIDE would be involved in regulating such events because they are not rated. I found this interesting PDF with some notes, although I think they could be improved. For example, it is not clear if the player loses the game after three passes.
- The exhibitor plays the white pieces on each board.
- Do not touch any chessman until the exhibitor arrives at your board. When the exhibitor is standing in front of your board, make your move (within 5 seconds) while the exhibitor is observing. The exhibitor will make a move on your board before going on to the next board.
- Participants, but not the exhibitor, must abide by the touch move rule. The exhibitor’s move is not final until he or she touches a piece on the next board.
- Each player is allowed three passes when the exhibitor arrives at his or her board. Using a pass means that the exhibitor will skip your board, but you will need to make a move (or use another pass) when the exhibitor comes back after visiting the other boards.
- Participants may not receive assistance from other players or bystanders during their games. Exception: participants may sign up as a pair and play on one board.
- Participants must take notation.
- If the exhibitor has any other rules, those will be announced at the start of the exhibition.
