With tennis matches, the most common betting option is betting on either player to win on the money line. You can also take advantage of the games spread here. Other common options include betting the over/under on the total number of games played in a match.
There are many different tennis betting strategies, but the best for us is to bet on favorites in Grand Slam events, as this has proven to be a profitable strategy over the years.
When a free bet wins, your sportsbook will only give you the profit from the wager and not the stake. This is known in the industry as a Stake Not Returned (SNR) free bet.
It's best to place a free bet at high odds due to the free bet stake not being returned, and this will allow you to maximise your profit. Bear in mind that the higher the odds, the larger your lay bet liability will be.
