Spectators are not permitted in the playing hall while games are being played. Players must exit the playing hall after finishing their games and reporting their scores.

When the first round is paired, parents are encouraged to accompany their players as they find their boards and listen to morning announcements. You may remain for the first five minutes of the first round only to observe your player and take a photo. After the first five minutes, we will ask you to return to the waiting area.

For rounds 2-5 parents who wish to escort their players into the playing hall may do so, but must then return to the waiting area. Since we need to keep the playing hall quiet, please, NO talking while finding your child's board.

Thank you for your understanding.
