English Tennis is the second most popular sport in the bookmaker business. The margin on tennis bets is usually lower (for the player) than on less liquid sports. The exception is matches involving well-known tennis players, even just one of them. In this case, one leg of the surebet or middle may prove to be overvalued, giving the player ample opportunity to exploit this imbalance and earn.
There is no need to delve into an analysis of the reasons why a surebet arises; it is enough simply to take into account that when a large number of tennis matches are being played, especially if Grand Slam tournament matches are taking place, the probability of good surebets appearing increases sharply, which a professional sports bettor should take advantage of.
It is quite possible to earn from tennis.
