of three players in a tournament being reduced to the two-player showdown, any leftover blinds from other rules are "written off" and the Simplified method is used, with the player "on the button" paying the small blind. Moving button: As in Simplified, the button moves to the left to the next active player, and the blinds move to the next two active players. However, any "missed blinds" are paid by the player whom they skipped as if they were due for the upcoming hand, with one blind paid per player, per hand, biggest blind first. Any blind a player misses on a given hand because a bigger blind was due will be paid by the player in the following hand. This is the most complex ruleset to implement, especially if multiple players leave, but it is the fairest method overall in terms of paying all due blinds and rotating last action. Dead button: Spots vacated by leaving players who would pay the small blind or get the button during the next hand remain open for the purposes of shifting blinds and button. Thus, the small blind may not be paid in the subsequent hand if the player due to pay the small blind has vacated the spot and, therefore, is considered "dead". However, there is always a big blind even if the spot is vacated by the player who is due to pay the big blind; in such case, the player seated to the left of the vacated spot pays the big blind. When the dealer button moves to an empty seat, it also is considered "dead", and the last active player before the empty seat retains the "privilege of last action" by default. While simple in tournament formats and the most equitable in terms of paying blinds as due and when normally expected, it can result in inequitable strategic situations regarding last action, and becomes harder to track if the table is "open" (players can come and go) as in a casino. In tournaments, the dead button and moving button rules are common (replacement players are generally not a part of tournaments). Online cash games generally use the simplified moving button as other methods are more difficult to codify and can be abused by players constantly entering and leaving. Casino card rooms where players can come and go can use any of the three rulesets, though moving button is
