You are not alone and I have made that mistake too. At that time I wanted to bet on a serie A match, without realizing it I bet on a women serie A match.  I even made an all in bet on a dice game when I hadn't changed the winning percentage.

Sometimes we are just not careful when placing bets or we are not focused when we feel sleepy. Since making that mistake, I have become more careful before placing a bet, always checking whether I am betting on the right choice.
