Tournament play will use a 'dead button.'
A 'dead button' is defined as a 'dealer button' that cannot be advanced due to elimination of a player.
A 'dead button' will occur when a new player is seated between the small blind and 'dealer button' or when the dealer button is moved in front of an empty seat.
When a 'dead button' situation is present, the 'dealer button' will be moved in such a way as to allow the maximum number of players to be dealt in, provided that the existing player is still able to post a full set of blinds, prior to receiving the dealer button.
