In sports betting, a double result bet is offered on the score of a game at both halftime and at the end of the game. This has become an increasingly popular betting option as opposed to simply betting on a team to win outright, which is a bet that can often have short odds.
Now, you think that the Bucks will control this game from beginning to end, but you are nervous about laying 10 points in case the Hornets get a back-door cover. Instead of taking Bucks -10, you can bet a double result that the Bucks win both the first half and the second half.
