Very good attempt. Does it always have to be evens or above odds?
It is a risky strategy but I bet backwards when it comes to GG. As in, I will look at bets that are Evs and above, 4/5 at the absolute lowest and then I look at the stats and see if I think there is value.
Couple of years back I had a very hot hand and I turned £10 into over £3000. Mostly, but not exclusively GG using this same system
Typically
Odds of Evens or there or there abouts
I want half of the home teams last 6 home games to be GG/ same with away team
Away team higher in the league/better than home team
If I see something stupid like a 3/1 for a single GG the above might go out of the window but typically like to stick to this method
Obviously it is not full proof but Man Utd v Liverpool was nailed on GG with price at 4/9 and look how that turned out
