  Any player who has joined the match will automatically receive events indicating changes made to the match. These events happen when a player joins the match, leaves it or posts a move.
  
  These events must be processed by each player prior to issuing additional commands. To do so, there is a parameter, called `lastEventId` that is required on some resources and must be set to the ID of the last event from the match.
