I have argued this on a thread before and not quite long, but maybe I am wrong. If you are not betting on sport like football, do not bother to choose either yes or no.
Since I have been betting, I have not thought of this before. Is the referee the reason you bet on yellow or red cards?
I love sports betting, especially soccer. On soccer, I bet on win/loss, corners, goals, and/or cards. But I have placed bets only on yellow cards. I have never placed bet on a red card as far as I can remember. And when I place bet on white card in maximum time I became winer and it make me a good profit.
There was some many years ago a referee called "the English idiot" where he was being the referee in Uefa Champions League final and he did a lot of mistakes. People got mad at him because for the slightest foul he would immediately show a yellow card and he even showed red card during that game. Even people in Uk as the referee was from Uk didn't like him at all but for people betting he was the best referee ever. People made a lot of money betting on over cards during the games he was being the referee in the Premier League. He was even gifted from UEFA as the best referee for something I don't remember now. So bottom line when you know the referee is like the one I describe here you are sure as hell you are going to bet on cards.
