Baseline and Line
EUROPEAN HANDICAPP Example
European handicap is a 3-way bet, similar to a 1X2 match result bet. That is why it is also found as “Single handicap” or “3-way handicap”. In any match with a significant difference in strength between the two teams, a handicap is placed on the outsider, to make it harder for the favorite to win the bet.
Here is a simple example for explanation:
* Handicap (-2) - You will win if your team wins the match with a goal difference of three or more.
* Tie (-2) - You will win if the team with (-2) Handicap wins the match by exactly 2 goals.
* Handicap (+2) - You will win if your team loses / draws / wins by 1 goal.
The Line in the code will tell you what the goal advantage is
The Baseline is used to indicate which team is getting the goal advantage (Home or Away)
Example:
Tottenham [HOME] (favorite) Vs. Eintracht[AWAY] (underdog)
