I love sports, but I admit, I'm too lazy. When I study bets on just one sport, especially a popular one like football, I don't get any more motivated or inspired. I like different sports, including uncommon, exotic, or those with complex rules. Although for me, even baseball is a game with complex and strange rules. I could say the same about handball, water polo, and horse polo, but if you think about it, horse polo has a lot of its own specifics related to horse control and the inconvenience of working with the ball, because you have to do many things at once. And the rules of such sports probably reflect many of these factors.
In short, I have adopted a formula for myself that your thinking as a bettor will develop when you study different sports and compare them with each other. Do you think this development really happens? If so, how does it manifest itself?
I have a rule that applies to here. If i feel like i am good at something, or know about some subject more then others, even though i have only studied about it for a while. Then i am probably just doing all the clichés and errors of that subject.
It's actually common thing i have seen in betting. People develop some kind of system and because they have a winning streak, they are now experts of that sport. It's known as Dunning-Kruger effect, where ignorant people are too ignorant to see that they are ignorant about something. And since no one wants to admit their ignorance, they decide that they probably know more then others.
Personally i don't think that studying some new sport could you give an financial edge over pure guesswork. Because even experts aren't making profits with them in a long run and i am far from expert. And if there's a way to make money in a long run, no one would give that information away, as it's making them rich.
