Ok this actually happens to my friend not so long ago, he is going on a boxing match and he will bet for the heavy favorite, then suddenly an unknown guy whisper to him, that the fight is going to be fixed and he supposedly heard it from the favorite to win, locker room, are you going to listen to that and bet for the underdog.
What's your take?
If I find out about such a thing my reaction will be to not bet on that particular fight and if possible I will never place a bet on the fights of those fighters ever again, there is a reason why fixing a sporting event is not only wrong but even illegal in many countries and that is because you expect that each participant has a desire to win and that they do everything they can to reach victory, once they break away from that principle then any competition becomes a joke and it is not worth watching it anymore.
