This is a system I've used a lot and that has never failed. The strategy I'm using is a betting method created for odd or even number of goals bets. You can use any league you want but I recommend Spain, England, Germany and France.
You need to wait until the 3rd match of the season and then choose a team that have finished all their matches with an odd number of goals in the first 3 matches. You bet even on that team. If the game doesn't end even you raise your stakes by 2.2 for the next game and bet even again. If this doesn't work, raise it to 4.84 and so on. I guarantee you that you'll be dining in caviar after this
[Editor's remark: although Bill guarantees caviar, we always warn our users - don't use progression systems - they sound good, but at some point you lose some bets in a row and that destroys your betting bank]
