I looked out for sports I wasn't conversant with the athletes and didn't know who was better at the sports and did a random prediction on the outcome of the game. I did it for swimming competition and some random boxing yesterday and out of up to 7 predictions I made, almost 6 went the way I predicted it.
Alot of gamblers today haven't had any experience in sports, neither do they know the capability of each teams in different leagues; It takes an active viewer to understand why, how and when a team is on form ... Why have casinos improvised over the years with options like head-to-head, winning probability scale, performance on last meeting etc?? That alone should tell you that they don't wanna have you guessing who's better, especially as a newbie.
I have not tried this in real games that involves using money but would want to know if anyone has ever tried it before.
I've tried it severally times.... It was almost part of our jobs - especially to old customers that had anyone behind the counter as a friend.. what I didn't get involved with was casino gambling.
