As a bettor, we usually combine our predictions with our gut feeling. Because sometimes the predictions we make do not give satisfactory results but our hunches can actually give the right results. But it still does not guarantee long term victory.
There is no battle that do not do this. It is always our gut feeling plus our prediction mixed with some hope that it will turn out to be a win. When it is a win, it makes us want to follow our hunch the more.
