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 don't actually bet on yellow or red cards but I have friends that do bet on that and they told me the reason why they bet on cards is not necessarily because of the referee but rather because of the club that are playing each other and if you check very well there are teams that like playing rough and there is no way, you will bet on them that they will not give you close or exactly what you play them but even as that I still don't know how to check it and I think the reason is because I'm not interested or I don't like the option because every sports gambler have there favorite option(s) they do play. And yes sometimes referee is also one of the reason some people play this option because there are some referee that don't tolerate, any slight mistake they will give card.
