Exactly

, that is why you should never bet matches like these if you dont have any info that might swing the odds either way.
I have a bet for all of you, Its called arbitrage betting.
This is 100% legal just so you know.
It works like this.
There are over a thousand bookie services over the internet providing odds for matches and they determine those odds by themselves. Sometimes some of the bookies mess up though and set extremely high odds compared to other bookie services, so good even that you could bet on both teams on different bookies and you would make money. This only applys to sports where there cant be a draw.
But for this to work and to be profitable, you have to have "arbs" being sent to you by e-mail constantly(there are numeral services for this) and have atleast 10 different bookieservices together with at least 2 grand (2000 dollar) on each and every one of them.
A friend of mine has been doing this for years, but he is highstakes and it takes up all of his time so i wouldnt recommend it for anyone, but he is earning though.
I personally just use his arbs to see which bookies have screwed up on setting the odds so that when i bet im sure ive got the highest odds for that match.
