would Beth's behaviour be acceptable in 1966?
I didn't start playing competitive chess until 1970 but then I often played club opponents who smoked and blew smoke in my direction. Beth's behaviour would be perfectly acceptable in 1966. Of course today smoking is not allowed in the playing area full stop. It is not only disturbing for non-smokers it is injurious to their health. What Beth was doing was insignificant by comparison
There are two issues you raise.
- "Whenever she made her move, she would wander around the hotel, looking at the game from far away"
This is what the FIDE Laws of Chess have to say:
11.2.1 The ‘playing venue’ is defined as the ‘playing area’, rest rooms, toilets, refreshment area, area set aside for smoking and other places as designated by the arbiter.
11.2.2 The playing area is defined as the place where the games of a competition are played.
11.2.3 Only with the permission of the arbiter can:
188.8.131.52 a player leave the playing venue,
184.108.40.206 the player having the move be allowed to leave the playing area.
If she can see the game then not only is she in the playing venue, as required by the Laws, she is actually in the playing area. Not only is her behaviour here within the rules but would also be within the rules if it was her turn to move. There is absolutely no requirement to stay glued to the seat.
- She would also sit on the side, fixing Georgi and even tapping her feet.
Staring at your opponent is perfectly acceptable. Tapping your feet or other nervous habits are more subjective but in general as an arbiter I give the benefit of the doubt to the nervous player and only act if the behaviour seems both deliberate and disturbing. Doing what she was doing from a distance doesn't qualify.
Some years ago I arbited a tournament where one of the young players appeared to have a nervous affliction which meant that his body, arms and head, were continually twitching in a way which was distracting to me as the arbiter, let alone the other players. However it seemed completely involuntary and none of the other players complained so I did my best to ignore it.
Every now and then I play somebody with a "nervous leg". It bounces up and down underneath the table. I try not to allow it to distract me and concentrate on my game as long as the movement doesn't disturb the table and the board. As an arbiter I know that I could complain to the arbiter but that would probably disturb my concentration more than the behaviour so I don't waste my time on mind games.
