betting is a form of betting on football in which teams are handicapped according to their form so that a stronger team must win by more goals for a punter betting on them to win.
The system originated in Indonesia and has gained popularity in the early 21st century. It is a form of spread betting. Handicaps typically range from one-quarter goal to several goals, in increments of half- or even quarter-goals.
Most importantly, Asian handicap betting reduces the possible number of outcomes from three (in traditional 1X2 wagering) to two by eliminating the draw outcome. This simplification delivers two betting options that each have a near 50% chance of success.
Asian handicaps are both good and bad for bookmakers. On one hand, they help bookmakers minimize risk by facilitating trading with parity or balancing the amount of wagering on each side of the match.
This enables bookmakers to take larger positions on major matches. On the other hand, Asian handicap markets are typically low margin offerings that do not contribute as significantly to the gross win as higher vigorish betting options like 1X2.
