English Tennis is the second most popular sport in the betting business. Tennis betting margins are generally lower (for the player) than those for less liquid sports. An exception is matches involving at least one famous tennis player. In this case, one of the shoulders or middles of the surebets may be overpriced, giving the player ample opportunity to play with this bias and win.
It is not possible to go into an analysis of the causes behind the appearance of surebets, but it is enough to note that when there are a large number of tennis matches, especially if Grand Slam tournament matches are taking place, the probability of good bets appearing increases dramatically, which should be used by a professional bettor.
It is even possible to make money from tennis.
