Thanks to all for reply and suggestions.
I know that all betting strategy is risky, but question is how much is it risky.
Like this strategy (+3 goals for your favorite), if you strong believe that your favorite team will not loss with 3 or more goals than you bet on your team it's very simple.
For me it's nonsense to AC Milan loss with 3 goal different from Atalanta and on that match they give 1.05 odd (that is 5%) for me that is very good odd for that tip. Or Anderlecht to loss with 3 goal different, and odd for that 1.03 (3%).
It's little hard to find on working days good match but on weekend is a bigger offer and one ticket can have over 1.10 odd (10%).
In any case we will see how will strategy work, today I will bet first ticket and share here after ended matches.
