not exactly sure how it works but i remember before a tourney starts being able to choose your seat by standing up and resitting down this should not be allowed as people can stand up and resit down to possibly gain positional advantage on another player before it starts if the ohter player does not move. people should be seated randomly and not allowed to move also people down the road could collude by doing this if the tournaments got big enough and people worked together and choose their tables and seating etc
