Every gambler knows what works for them but you shouldn't be bringing an idea that won't work for majority of the players to the public as you'll be tempting others to try it and when they do, they'll fail. I prefer betting on the favorite team and win small than risking it for the underdog.
Betting on the favorite team is surely safer and you can accumulate your profit after few matches, but if the odds as low as @1.10, I wouldn't bet because it need ten time of bets to double your money. But you can increase your odds by parlay bets, just pick favorite team and you can earn more money.
I think it's better than put on an underdog where the possibility to win is lower.
