Money cannot be added to or taken from the table, a seat cannot be changed, a player cannot be substituted for another, no other change which would affect the conditions of the contest shall be permitted once the play of the hand has begun. If a player is aware of a procedural error, or aware that the action has passed his position in error and he has not acted, it is his obligation to protect the game and his right to act by objecting immediately. If a player waits until it is to his advantage to object to an error, then the error shall have deemed to have never taken place, and further that player shall forfeit all interest in the pot. However only action made prior to the discovery of an error will be used to determine substantial action. In the event of dispute as to whether action was prior to or subsequent to discovery, there shall be a rebuttable presumption that the action was subsequent and therefore does not constitute part of substantial action.
Dead hands are all hands that are no longer eligible to win the pot.
A player who throws his cards facedown with a forward motion has surrendered his hand and his interest in the pot, and his hand is dead if either the hand touches the muck or another player has acted behind him. That said, in the floorperson's discretion the hand may be ruled live if it is clearly retrievable and such decision serves the best interests of the game. Retrieving a dead hand shall be discouraged, however, and shall only be permitted in extreme circumstances where fairness is clearly served. If a player discards his hand but no player has acted behind him, then the hand may be retrieved at the player's request. Cards which have touched the muck cannot be retrieved.
