Sports betting is an area of gaming in which the player is not in direct competition with the house. In most of casino games (such as craps, keno, slot machines, baccarat, black jack and roulette), the house has a statistical advantage. In sports betting, however, players can gain an advantage on the house when they can identify the events where the offered odds do not accurately reflect the true odds for the events’ outcome. The punter needs to realize that the offered odds are not an odds compiler’s prediction of event’s outcome. Rather, the odds are designed so that equal money would be bet among all outcomes.
Bookmakers make their money at the expense of the people who bet impulsively. For most punters, the main thing about betting is to add little extra excitement to the sporting event. Therefore, it is vital for a bookmaker to create odds such that the distribution of betting volume is in balance. If the betting volume is evenly distributed, the bookmakers will always get their in-built percentage. Thus, the odds are not always the appropriate measures of the teams’ relative strengths. If a punter is capable of predicting the outcome correctly, there are chances for profitable betting. The main rule for the punter is to be selective. Only bet if the odds are on your side. If Brazil is expected to beat Poland 19 times out of 20, then the odds 1/9 (which says that Brazil wins 18 times out of 20) are a good value. This strategy is called value betting.
