No, they are different types of arbitrage. The surebet strategy means that a player bets with different bookmakers and receives a profit.
For example, the bets for a Zenit vs. CSKA football match according to Total Goals are as follows:
- The first bookmaker offers over 2,5 total goals at odds of 1,91.
- The second bookmaker offers under 2,5 total goals at odds of 2,25.
Regardless of the outcome of the game, the player will receive a profit of 3,3 %.
A middle betting strategy offers the opportunity to win both bets at the same time. Each middle has a certain width.
For example, the bets for a Los Angeles Lakers vs Phoenix Suns match are as follows:
- The first bookmaker offers over 159,5 total goals at odds of 1,96.
- The second bookmaker offers under 161,5 total goals at odds of 1,96.
The width of the middle is 2 points; that is, with a total of 160 and 161 goals, the player betting on the middle wins both bets. In any other case, the player will receive a profit from one of the bets, with 2% less the bankroll amount.
