We are a bunch of seniors who are so grateful for BBO during the pandemic. We play casual bridge and switch seats (partners) after 8 hands. When we make this switch, the host then resets the score and requests a redeal. This is because the players have seen the hands dealt to their previous seats. Sometimes redeal is not permitted. More often it is allowed and the players have to agree. Does anyone know what prompts the redeal not permitted situation?
