Handicap betting is where a points/stat margin is applied to the favored team/player to create more level odds for each outcome.
The following example shows how the following handicap market can be resulted as winning options:
Team A +1.5 = two winning options:
1. Team A needs to win the game by any margin
2. Team A needs to lose by 1 point.
TEAM B -1.5 = one winning option:
1. Team B needs to win the game by more than 2 points.
