When you place a handicap bet ("+" or "-"), the team/player you bet on will have an advantage/disadvantage from the start, depending on the type of handicap chosen. In order for the bet to be a winning bet, the team/player must score more goals/points in order to get the desired result with the chosen advantage or disadvantage.
Here is an example: "Manchester United -1" means that the team starts with a handicap of one goal. For the bet to win, Manchester United must win by a two-goal margin. Basically, the handicap is added to the score at the end of the match and the final result must be in favor of the team you bet on.
On the other hand, if you bet on "Manchester United +1", the handicap works in their favor and they start the match with a one goal advantage. For your bet to be a winner, Manchester United can either win the match outright or draw as the handicap gives them an extra goal on the scoreboard.
The purpose of the handicap market is to level the playing field, especially when there is a clear discrepancy between the two teams or players. This creates a more balanced betting opportunity, providing better odds for favorites who win convincingly and incentivizing bets on those who don't have an extra edge.
In conclusion, the sports betting handicap market introduces an interesting twist, as it takes into account the advantage or disadvantage, a team or player has before the match begins.
By understanding the implications of the given handicap, you can make informed decisions and potentially enjoy greater success in your betting.
