English Negative middles in betting are a strategy in which the player bets on opposing outcomes of the same event, with the possibility that both bets can win simultaneously under certain conditions. In general, these middles mean that both outcomes cover different possibilities of the same event, but the probabilities do not fully overlap. When the event result falls within the middle, both bets are successful.
Example of a negative middle
Imagine a football match in which you have two betting options on the total number of goals:
- Over 2,5 goals at odds of 2,0
- Under 3,5 goals at odds of 1,8
For example, your betting budget is 100 dollars. You place 50 dollars on the first bet at odds of 2,0 and 50 dollars on the second bet at odds of 1,8.
Possible betting results after the match:
- If exactly 3 goals are scored, both bets win, and you receive the payout from both: 2,0×50+1,8×50 = 175 dollars.
- If 4 or more goals are scored, only the first bet wins with a payout of 2,0×50 = 100 dollars. The second bet loses, resulting in a net balance of 0 dollars.
- If 0, 1 or 2 goals are scored, only the second bet wins with a payout of 1,8×50 = 75 dollars. The first bet loses, and the final result is negative: -25 dollars (hence the name "negative middle").
Characteristics and risks
- Potential gain: If the event result falls within the "middle" (in this example, exactly 3 goals), both bets win, resulting in an increased profit.
- Risk of loss: Unlike surebets, where any combination of results generates a profit, some results in negative middles may be unprofitable.
