English No, there are different types of arbitrage situations. The surebet betting strategy involves the bettor placing bets with different bookmakers on opposing outcomes for one and the same event in order to win.
For example, let us take the bets for a Zenit - CSKA Moscow football match on Total Goals.
- Bookmaker №1 offers odds on Total over 2,5 - 1,91
- Bookmaker №2 offers odds on Total under 2.5 - 2.25
Regardless of the score, the player will receive a profit of 3,3% of the bankroll.
The middle is a strategy that assumes the possibility of winning both bets simultaneously. Each middle has its own width.
For example, let us take the bets on a Los Angeles Lakers - Phoenix Suns basketball match
- Bookmaker N°1 offers odds on Total over 159.5 - 1.96
- Bookmaker №2 offers odds on Total under 161,5 - 1,96
The middle's width is 2 points. With a Total of 160 and 161, the person who places bets on this middle will win both bets. In all other cases, the player will win one of the bets and have a general "negative" of 2% of the bankroll.
