Betting on matches where the referee has an influence on the outcome is a factor that cannot be ignored. Referees can have a big influence on the outcome of a match through decisions on cards, penalties or other controversial situations. Referees tend to favor a certain team or often make controversial decisions in big matches. Bettors need to keep track of information about referees and their working style to make accurate betting decisions. Keywords such as "referee betting", "referee decision betting", or "controversial situation betting" will be useful.
