Indeed, tennis odds are not attractive at all
that's why we say it's better to back the underdog.
The Mayer bet is an isolated bet, so i'm not gonna chase if lost, i 'm taking it because i'm very confident, there won't be many of that kind of bets here.
What should i recommend for you ?
I think tennis is one of the toughest sport to bet on unfortunately, the reason why i bet on it is because it's by far my favourite sport, but i won't recommend any "newbie" to bet on it. I think you should first watch matches without betting, i don't recommend you to bet on this if you are not into it, too dangerous.
Thanks for your reply anyway! What sports do you usually bet on ?
